WEED CONTROL IN WINTER CROPS 2018 | 1

Several new herbicides have been registered in the past 12 months, or that have new approved use patterns for winter crops for the 2018 season.

Aptitude® (375 g/kg metribuzin [Group C] and 90 g/kg carfentrazone-eythl [Group G]) herbicide is an early post-emergence herbicide to control certain broadleaf weeds in winter cereals. Aptitude® herbicide is a fast acting contact herbicide and controls weeds through a process of membrane disruption and inhibiting photosynthesis at photosystem II.

Butisan® (500 g/L metazachlor) (Group K) is a pre-emergent herbicide to control annual ryegrass, wild oats and wireweed in canola from BASF. Butisan® has a number of key features:

Higher levels of weed control than propyzamide, trifluralin and atrazine, even in paddocks where resistance is not a major factor.

Suitable for use in all canola production systems; triazine tolerant, Roundup Ready®, Clearfield® and conventional varieties.

Activated in low moisture conditions, and moves back into the furrow providing superior in-furrow weed control compared with commercial standards.

Greater pre-emergent control, reducing the number of panicles produced and weed seed set.

Residual control period of 9–12 weeks depending on soil moisture and rainfall conditions, with the potential to reduce pressure on in-season sprays.

Complemented well by over the top applications of atrazine, glyphosate, Intervix® and Group A herbicides in well-managed weed control programs.

Picoflex® (240 g/L picloram) is a new herbicide from Adama that offers improved levels of control on problem weeds in cereals such as climbing buckwheat when added to MCPA or 2,4-D products. In addition, the product can be used in fallow situations to improve the control of hard to kill weeds such as camel and prickly paddy melon as well as sowthistle.

Pixxaro™ herbicide with Arylex™ active (250 g/L fluroxypyr methyl ester + 16.2  g/L halauxifen methyl ester) is a new product from Dow AgroSciences for broadleaf weed control in both cereals and fallow. The addition of the proven Arylex molecule to fluroxypyr (Starane®) broadens the weed spectrum of Starane® as well as making Pixxaro™ more robust on Starane®-susceptible weeds. Pixxaro™ is a non-ALS option for broadleaf weed control in both cereals and fallow with a wide crop stage application window

(3 leaf [Z13] to flag leaf [Z39]) in cereals. Some of the weeds controlled with Pixxaro™ are marshmallow, milk thistle/sowthistle, prickly lettuce, Mexican poppy, deadnettle, fumitory and red pigweed.

Sharpen® WG (700 g/kg saflufenacil), the herbicide use pattern has changed and has been registered for pre-harvest use in wheat, barley (feed and malt) and triticale. It is registered for wild radish seed set reduction and it can be applied from Z71 (milky dough) to Z83 (soft dough). Apply at least 14 days before harvest.

Sakura® 850 WG (850 g/kg pyroxasulfone) herbicide has had additional crop types added to the label, which now includes chickpea, field pea, lentil and lupin at the rate of 118 g/ha. See label for a list of weeds controlled or suppressed.

Talinor® (37.5 g/L bicyclopyrone + 175 g/L bromoxynil + 9.4 g/L cloquintocet-mexyl) is a new post-emergent broadleaf selective herbicide for use in wheat and barley from Syngenta. It contains two herbicide modes of action, bicyclopyrone (Group H) and bromoxynil (Group C) for resistance management and robust weed control. It has excellent activity on wild radish and Indian hedge mustard, including phenoxy-resistant biotypes. Strong activity on a range of tough to kill broadleaved weeds and has good compatibility with MCPA and Lontrel®. It has a flexible crop application window (Z12–32). The built-in crop safener provides good crop safety in wheat and barley crops. Application to small weeds early in the crop enables cereals to obtain maximum yield. The plantback is four months for summer crops and pastures and nine months for winter crops and pastures.

Terrain™500 WG (500 g/L flumioxazin), a Group G herbicide from Nufarm, has an updated use pattern and the previous 30g/ha tank mix rate, it is now also registered for pre-emergent (IBS, knife point and presswheel only) use in wheat at 120 g/ha (not durum wheat) and 180 g/ha in faba bean, chickpea, field pea. For weeds supressed please refer to the label.

Wipe-Out® Pro (540 g/L glyphosate) is a new, unique fully loaded glyphosate knockdown formulation from Adama. The product, being fully loaded, requires no additional surfactants and with its monoethanolamine salt carrier offers improved compatibility with 2,4-D and other tank mix partners. In addition to this improved compatibility the product is also low foaming and is easy to pour and pump in cold conditions. Registered for both pre-plant applications and as an in-crop harvest aid.

Effective weed control in winter crops is a vital part of successful and profitable crop production. Yield losses from weeds can vary enormously from being almost negligible to a complete loss.

Weeds lower crop yields by competing for soil moisture, nutrients, space and light and can carry diseases that attack crops. This competition reduces grain yield and quality, and can impede harvesting.

Some weeds can restrict cropping options as herbicides for control are sometimes limited. Thoroughly investigate which weed species are likely to germinate in a paddock before sowing crops with limited herbicide control options.

Weed control is a numbers game. Growers should aim to reduce numbers and keep them low with an ongoing program. An integrated weed management system, combining all the available methods, is the key to successful weed control.

Crop rotation A well-managed rotation in each paddock, which alternates pastures, broadleaf and cereal crops, is a very useful technique for controlling weeds. For example, grass weeds are more easily and cheaply controlled chemically in broadleaf crops, whereas broadleaf weeds are much easier to control in cereal crops. In parts of northern NSW, alternating summer and winter crops is a time-honoured strategy for weed control. Good crop rotations can substantially reduce the cost of chemical weed control.

Haymaking or silage-making in crops and pastures can effectively reduce the weed burden.

Pasture management techniques such as pasture topping by mowing or using herbicides, spray grazing, strategic heavy grazing or burning can all be part of your weed control program. Cleaning grasses out of legume pastures in winter is a common practice, which involves spraying grasses such as barley grass and vulpia out of pastures in winter to stop seed set, improve nitrogen build-up and reduce root diseases in the following cereal crops.

Good agronomic practices such as using weed-free seed, sowing on time with optimal plant populations and adequate nutrition all contribute to good weed control management. Be extremely vigilant with new weed incursions, not allowing them to set seed. Some crops and varieties are more competitive against weeds than others. All weeds growing in a field should be controlled before the crop emerges. Large weeds that have not been controlled before, or by, sowing prove most difficult and often impossible to manage with in-crop herbicides.

Timely cultivation is a valuable method for killing weeds and preparing seedbeds. Some growers use varying combinations of mechanical and chemical weed control to manage their fallows or stubbles.

Harvest weed-seed management is now considered imperative in both delaying and dealing with herbicide-resistant weed populations. See the Grains Research and Development Corporation (http://www.grdc.com.au/) website for further information.

In-crop weed control A wide range of pre-emergent and early post-emergent herbicides are available. Weeds should be removed from crops as early as possible and no later than six weeks after sowing to minimise yield losses. Yield responses will depend on weed species, weed and crop density and seasonal conditions. The growth stages of both weed and crop, as well as the effects of environmental conditions on plant stress and herbicide efficacy must be considered before spraying. Tolerance to herbicides varies between cereals and between the varieties of each cereal. Read herbicide labels carefully for these details and information on the best conditions for spraying. See Sensitivity to herbicides in winter crop varieties on page 100.

Herbicide resistance in weeds is an increasing problem in NSW and one to which growers must remain alert. It is one of the biggest agronomic threats to cropping sustainability. However, good crop and pasture rotation, rotating herbicide groups and combining chemical and non-chemical weed control methods can help manage the problem. Each table throughout this guide lists the mode of action group for each herbicide (see Herbicide resistance management on page 59).

Useful resourcesThe Cotton Field Awareness Map is an industry initiative which has been designed to highlight the location of cotton fields. The service is provided free of charge with the purpose of minimising off-target damage from downwind pesticide application, particularly during fallow spraying.

Farmers, farm managers, resellers, consultants, agronomists, applicators and contractors are encouraged to input their cotton field(s). Users can also access the Cotton Map to check the location of the paddock(s) they may be planning to spray to assess the proximity of the nearest cotton crop.

The map is a collaboration between Cotton Australia, Cotton Research and Development Corporation (CRDC), Grains Research and Development Corporation (GRDC) and Nufarm Australia Limited, developed to meet industry needs. Go to www.cottonmap.com.au

A decimal scale describing cereal crop growth stages is now widely used.

This scale, called the Zadoks decimal code, describes the principal growth stages, labelled 0 to 9:

0 Germination1 Seedling growth2 Tillering3 Stem elongation4 Booting5 Ear emergence6 Flowering7 Milk development8 Dough development9 RipeningEach primary growth stage is further subdivided into secondary stages extending the scale from 00 to 99.

The first number represents the growth stage and the second the numbers of plant parts, e. g. Z12 indicates a young plant with only two leaves fully unfolded, commonly referred to as the 2-leaf stage.

A series of pairs of numbers can be used to further describe the growth stage. For example Z14/21 indicates the main tiller with four fully unfolded leaves, commonly referred to as the 4-leaf stage, but this plant has one more tiller. Note that additional tillers are counted separately from the main tiller.

The main stages of interest to cereal producers applying herbicides are:

1. Seedling growth2. Tillering3. Stem elongation4. BootingThe Zadoks scale is based on the individual plant, not the general appearance of a crop. Therefore, to use the scale, a representative selection of plants should be examined from a paddock.

Growth terms used elsewhere in this guide, extracted from registered labels, and their Zadoks equivalents are:

3-leaf: Three fully unfolded leaves on main shoot only. Zadoks 13.

5-leaf: Five fully unfolded leaves on main shoot only. Zadoks 15.

Tillering – Tiller formation period.

Plants past seedling stage and before stem elongation. Zadoks 21 to Z29.

Jointing: Crop becoming erect or booting up to the stage when the flag leaf is just visible. Zadoks 31 to Z37.

Boot: Head plainly felt in stem before head emergence. Zadoks 40 to Z45.

Crop growth stage2 leaf stage

Two leaves (L) have unfolded; third leaf present, yet to fully expand.

Start of tillering

First tiller (T1) appears from between a lower leaf and the main shoot. Usually 3 or 4 leaves are on the main tiller.

Tillering

Tillers come from the base where leaves join the stem and continue forming, usually until there are 5 leaves on the main shoot. Secondary roots developing.

Fully tillered

Usually no more tillers form after the very young head starts forming in the main tiller.Tillering completed when first node detected at base of main stem.

Start of jointing

Jointing or node formation starts at the end of tillering. Small swellings – joints – form at the bottom of the main tiller. Heads continue developing and can be seen by dissecting a stem.

Early to mid booting

The last leaf to form – the flag leaf – appears on top of the extended stem. The developing head can be felt as a swelling in the stem.

Using the growth stages of cereal crops to time herbicide applications The recommended timing for applying each herbicide is indicated in the chemical control tables in this guide.

The terms ‘early tillering’ and ‘late tillering’ are not definitive and are commonly used in a very general sense. The number of fully emerged main shoot or stem

leaves, together with the number of tillers when there is more than one, is the only accurate measure of the growth stage of a cereal plant. See the diagrams, and Cereal growth stages – Zadoks on page 4.

Recommended and preferred timingLess preferred timing

The recommended application timing has been determined after significant research by the marketing company, aiming to minimise crop damage and maximise yield. Pay attention to two vital stages of crop development: at 3–5‑leaf stage or when tillering starts; and at the start of jointing.

In many cereal crops:• 3 leaf (on main stem) stage is before tillering.• 5 leaf (on main stem) stage coincides with early tillering.• 6–7 leaf (on main stem) stage coincides with mid to fully tillered stage.• Jointing or node formation indicates the start of the reproductive phase in the crop, and tillering can be said to be complete, i.e. fully tillered.

Annual weeds typically compete most with cereals and broadleaf crops when the crops are in their earlier growth stages e.g. tillering in cereals. Weeds should be removed no later than six weeks after sowing to minimise losses, however, only rarely are selective herbicides completely non-toxic to the crop. See the Sensitivity to herbicides in winter crop varieties on page 100 for guidance. Early post-emergence control nearly always results in higher yields than treatments applied after tillering in cereals or branching in broadleaf crops.

Points to remember for successfully using herbicides:

• Plan the operation: check paddock sizes, tank capacities, water availability and supply.

• Carefully check crop and weed growth stages before deciding upon a specific post-emergent herbicide. Use the diagrams in Cereal growth stages – the Zadoks scale on page 4. Read the label: check to make sure the chemical will do the job; note any mixing instructions, especially when tank mixing two chemicals. This document is a guide ; it cannot tell you all the information you need to know.

• Follow the recommendations on the label.• Conditions inhibiting plant cell growth, e.g. stress

from drought, waterlogging, poor nutrition, high or low temperatures, low light intensity and disease or insect attack can inhibit good herbicide uptake and movement.

• Use good quality water, preferably from a rainwater tank. Bore, hard, dirty or muddy water needs special additives or conditioners to improve results with

certain herbicides. See Water quality for herbicide application on page 15.

• Use good equipment checked frequently for performance and output – see Boomspray calibration on page 20.

• Check boom height with spray pattern operation for full target coverage.

• Check accuracy of boom width marking equipment.• Check wind speed:

ū a light breeze helps herbicide penetration into crops. ū Do not spray in strong wind; there could be spray drift onto sensitive crops and pastures, roadways, dams, trees, watercourses or public places. Note: All chemicals can drift – see Reducing herbicide spray drift on page 25.

• Do not spray if rain is imminent or when heavy dew or frost is present. See Rainfastness – stock withholding periods – harvest withholding periods on page 12 for rainfast periods.

• Calculate the amount of herbicide required for each paddock and tank load. Add surfactant where recommended. See Boomspray calibration on page 20.

• Select the appropriate nozzle type for the application, see Nozzle selection for post-emergent herbicides and fungicides on page 26. Beware of compromising nozzle types when tank mixing herbicides with fungicides or insecticides.

• Keep a record of each spray operation How to complete your Pesticide Application Record Sheet on page 23. Poison warnings on herbicide labels

The Poisons StandardHerbicides are classified into four categories (schedules) in the Poisons Standard based on the herbicide’s acute health hazard to the user. Each schedule has a corresponding signal heading, which appears in large contrasting lettering on the label of the herbicide product.

The Safety Directions specify what personal protective equipment should be worn, and what safety precautions should be taken, e.g. do not inhale spray mist. The First Aid instructions specify what action should be taken in the event of a poisoning. Safety Directions and First Aid Instructions may be different for different formulations of the same pesticide.

Before opening and using any farm chemical, consult the label and Safety Data Sheet (SDS) for specific Safety Directions. The hazardous chemicals section of the Work Health and Safety Regulation requires resellers to provide end users with an SDS. If you suspect a poisoning, contact the Poisons Information Centre emergency phone (24 hour) 131 126.

Identifying cereal seedlingsIt is extremely important to accurately identify cereal plants before applying a herbicide for weed control. Cereal seedlings are identified by looking at four important characteristics. This involves taking a close look at the junction of the leaf blade and the leaf sheath (a hand lens is useful).

KEY: hr = hours, d = days, w = weeks, mo = months

q For pH 8.6 and above tolerance of crops (grown through to maturity) should be determined on a small scale, in the previous season, before sowing into larger areas.

w When applied to dry soils at least 15 mm of rain must fall prior to the commencement of the plantback period.

e Express® is broken down in soil, primarily by chemical hydrolysis, but to a lesser degree by microbial degradation. Breakdown is fastest in warm, wet acid soils and slower in cold alkaline soils. For these summer crops, if minimum soil temperatures at planting depth are less than or equal to 15 °C for three consecutive days, then plantback intervals should be extended to 21 days.

r Black cracking clays. During drought conditions the plantback period may be significantly longer.

u Plantback refers to rapeseed not canola.

i Soil pH determined by 1:5 soil:water suspension method.o Do not plant susceptible crops until 9 months after application of Eclipse®.

Susceptible crops include canola or other brassica crops, field peas, beans, medics, lucerne and sub‑clover.

a Minimum recropping periods are influenced by numerous factors. See label for further information.

s Goal® herbicide at up to 75 mL/ha may be safely applied 1 day before planting wheat, barley, oats, triticale, canola, lupins, faba beans, field peas, lucerne, clover, medics, ryegrass, phalaris and cocksfoot and 7 days minimum before planting cotton or soybeans, provided minimum tillage planting equipment is used with minimal soil disturbance.

g Minimum recropping periods are influenced by numerous factors. See label for further information.

The following plantback periods are a guide only based on label recommendations. The time indicated between application and safe crop rotation intervals will depend on a range of factors including rainfall (amount and intensity), soil type (pH, soil biological activity and organic carbon),

soil type variability within a paddock, and temperature and herbicide rate. Some crops are more sensitive to various herbicide groups than others. Always take a conservative approach to plantback periods, especially with sensitive or high input crops.

Table 3. Guidelines for crop rotations – In-crop herbicides

KEY: d = days, w = weeks, mo = months

q For pH 8.6 and above tolerance of crops (grown through to maturity) should be determined on a small scale, in the previous season, before sowing into larger areas.

w When applied to dry soils, at least 15 mm of rain must fall before plantback period starts.

e Additional rainfall/soil moisture requirements need to be observed – see label.r Rainfall of less than 250 mm following Atlantis® OD use will result in extended

re‑cropping intervals for winter crops sown the following season. Patchy rain with extended dry periods may also extend this period. Rainfall of less than 500 mm may result in extended re‑cropping periods for summer crops in the following year. Use in soil above pH 8.5 is not recommnded.

t pH < 8.0 (under conditions of good seasonal rainfall) = 9 months, pH > 8.0 = 21 months.

y Prolonged dry periods or cold conditions may result in extended re‑cropping intervals, even if rainfall exceeds the required amount. Use on soils with pH less than 7.0 may

result in extend recropping intervals. Cultivation is recommended before recropping. u 100 mm minimum rainfall total between herbicide application and planting subsequent

crop.i 250 mm minimum rainfall total between herbicide application and planting subsequent

crop.o 350 mm minimum rainfall total between herbicide application and planting subsequent

crop.a 500 mm minimum rainfall total between herbicide application and planting subsequent

Table 4. Rainfastness – stock withholding periods – harvest withholding periodsThis table lists:• Rainfastness. The time interval required between

herbicide application and rainfall. Avoid applying herbicide when rain is imminent. However, certain herbicides may not be affected by some rain during or after spraying. The table suggests the time needed between spraying and rainfall for each herbicide to be effective.

• Stock grazing or fodder production withholding periods. This is the number of days you must wait after spraying before allowing stock to graze the area, to ensure the animal produce is free of pesticide residues. Check latest MRL data with individual companies for produce to be sold on export market.

WARNING — When spraying use extreme caution and carefully consider the possibility of spray drift onto susceptible plants – e.g. cotton, canola, lucerne, grapevines, horticultural crops, belah and kurrajong trees.

IMPORTANT NOTE: Before using these products for this use check registration.

Harvest aid or salvage spraying winter crops

Salvage spraying or pre-harvest desiccation is required in some years to desiccate weeds and assist timely harvesting of winter crops. Situations do arise due to late establishing weeds combined with wet and prolonged springs or harvest periods, where salvage spraying may be necessary.

Weeds such as skeleton weed, bindweed, melons, sowthistle, prickly lettuce, fat hen and New Zealand spinach can interfere with harvesting whilst weed seeds such as saffron thistle, rough poppy, Mexican poppy and black/field bindweed can contaminate grain.

Water quality for herbicide application

Good quality water is important when mixing and spraying herbicides. It should be clean and of good irrigation quality. Poor quality water can reduce the effectiveness of some herbicides and damage spray equipment. Some poor results with herbicides could possibly be due to water quality problems.

Effects of water qualityWater quality depends on the source of the water (rain-fed tank, dam, river, bore or aquifer) and the season (e.g. heavy rain, drought). There are several characteristics of water quality which affect chemical performance.

Dirt: Dirty water has very small soil particles (clay and silt) suspended in it. These soil particles can absorb and bind the chemical’s active ingredient and reduce its effectiveness. This applies especially to glyphosate, paraquat and diquat.

Dirt can also block nozzles, lines and filters and reduce the sprayer’s overall performance and life. As a guide, water is considered dirty when it is difficult to see a 10¢ coin in the bottom of a household bucket of water.

Water hardness: Water is termed hard when it has a high percentage of dissolved minerals such as calcium, manganese or magnesium. Hard water won’t lather with soap and can cause some chemicals to precipitate. Susceptible chemicals often have agents added to overcome this problem.

Formulations of 2,4-DB are particularly sensitive to hard water (>400 ppm CaCO3 equivalent). Other herbicides such as glyphosate, 2,4-D amine and MCPA amine, Lontrel™ Advanced and Tigrex® can also be affected.

Hard water can affect chemicals in the following ways:

• Causes some chemicals to precipitate.• Can affect the wetting, emulsification and

dispersion properties of some surfactants.Water pH: pH is a measure of acidity and alkalinity that ranges between 1 and 14. A pH of 7 is neutral, less than 7 acid and more than 7 alkaline. Most natural waters have a pH of 6.5–8.

In highly alkaline water (pH >8) many chemicals undergo a process called alkaline hydrolysis. This process causes the active ingredient to break down into other compounds that can reduce the pesticide’s effectiveness over time. This is one reason why spray mixes should not be left in spray tanks overnight.

Very acid water can also affect the stability and physical properties of some chemical formulations.

Dissolved salts: The total amount of mineral salts dissolved in water is usually measured by the water’s electrical conductivity (EC).

The EC of bores and dams depends largely on the salt levels in the rock and soil that surrounds them. During a drought, water salinity increases.

Very salty water can cause blockages in equipment and is more resistant to pH changes.

Organic matter: Water containing a lot of organic matter, such as leaves or algae, can block nozzles, lines and filters. Algae can also react with some chemicals, reducing their effectiveness.

Temperature: Very hot or cold water can affect the performance of some chemicals.

Improving water qualityWater needs to be tested to see whether it will affect chemical performance. There are commercial products available to reduce pH (e.g. Primabuff®, and LI 700 and Hotup®), soften hard water and clear dirty water. To reduce the effects of very salty water, you may need to mix water from several sources.

Using adjuvants, surfactants and oils with herbicides

Herbicides often need help to spread across the leaf and penetrate the leaf surface of weed targets to give the best results.

Some herbicides have sufficient adjuvant and require no additional surfactants to perform well. However, some do and this is usually detailed on the herbicide label. Always read the herbicide label before opening the container and heed the information printed there.

An adjuvant is any additive to a herbicide that is intended to improve the effectiveness of the herbicide. There are many products that have been developed to help herbicides to contact the weed target, then remain and penetrate the weed leaf.

The APVMA classes adjuvants into two categories:

1. adjuvants that enhance product efficacy2. adjuvants that improve the ease of application.

Adjuvants that enhance product efficacyWetters/spreaders (enhance adhesion to, and spray droplet spreading on, target surfaces by reducing the surface tension of the pesticide formulation and improving coverage) such as:

• non-ionic surfactants – non-reactive, i.e. they do not have a negative charge or a positive charge; they remain on the leaf once dry and allow rewetting after rain, permitting additional pesticide uptake

• anionic surfactants – negative charge• cationic surfactants – positive charge• amphoteric surfactants• organo-silicate surfactants• acidified surfactants.Stickers (increase pesticide adhesion to target surfaces) could be:

• latex-based• terpene/pinolene• pyrrolidone-based.Penetrants (improve active ingredient transfer from the target surface to interior tissues), which might include:

• mineral oil• vegetable oil• esterified vegetable oil• organo-silicate surfactants• acidified surfactants.Extenders (enhance the amount of time the active ingredient remains toxic by increasing resistance to environmental degradation), which might be:

• ammonium sulfate• menthene-based.

Humectants (increases the density/drying time of an aqueous spray deposit), which could be:

• glycerol• propylene glycol• diethyl glycol.

Adjuvants that make application easierAcidifying/buffering agents (adjust the pH of alkaline or acidic water to minimise the pesticide decomposing through alkaline hydrolysis).

Anti-foaming/de-foaming agents (reduces or suppresses foam formation in the spray tank to prevent overflow): dimethopolysiloxane.

Compatibility agents (permits different agrochemicals to be mixed by preventing antagonism between different ingredients in the spray solution) such as: ammonium sulfate.

Drift control agents (alter the viscoelastic properties of the spray solution yielding a coarser spray with greater mean droplet sizes):

• polyacrylamides• polysaccharides.Dyes (commonly used for spot or boom spraying herbicides to detect missed spots or to avoid duplication.

Water conditioners (prevents a reaction between hard water ions in spray solutions and suppresses precipitate or salt formation): ammonium sulfate.

Factors affecting adjuvant use include:1. Crop safety – adding an adjuvant can reduce

herbicide selectivity and thereby increase crop damage. This is not an issue for fallow and pre-emergent herbicides.

2. Effectiveness or activity – adjuvants are usually added to increase the effectiveness of herbicides. However, using the wrong type or rate can reduce effectiveness, such as decreasing herbicide retention on leaves.

3. Water hardness – hard water can lead to poor mixing with the chemical. This particularly occurs with emulsifiable concentrates. High levels of calcium and magnesium ions bind with amine formulations causing them to be less soluble and therefore less effective.

4. Water temperature – low water temperature can lead to gelling in the tank. High concentration herbicides might not mix and surfactants could perform poorly.

Table 7 on page 17 lists some of the available adjuvants.

Tips for tankmixing herbicidesTank-mixing herbicides is a common practice to improve weed control and broaden the target weed spectrum. There could also be some advantages that help to avoid herbicide resistance problems.

Many tank-mixes are included on registered herbicide labels.

Generally, provided herbicides are registered for a particular use, they may be tank-mixed if they are compatible and label mixing instructions are followed.

Note that some herbicides, although being physically compatible, can be antagonistic to weed control. This information is usually outlined on herbicide labels under compatibility. Ratios for tank-mixing, crop safety, herbicide efficacy and special use of adjuvants, also need to be considered.

The order in which herbicides are mixed is also important – the following mixing sequence is usually followed:

1. Water conditioning agents (if required – e.g. LI 700, Liase® or Primabuff®).

2. Water dispersible granules (WG)/dry flowable products (including those in water-soluble bags first).

3. Wettable powders (WP).4. Flowables or suspension concentrates (e.g.

atrazine–simazine liquids).5. Emulsifiable concentrates (EC) (e.g. Trifluralin,

Topik®, Kamba®, Bromoxynil).6. Water-soluble concentrates (e.g. glyphosate,

Amicide® Advance 700, Spray.Seed® 250, Gramoxone® 360 Pro).

7. Surfactants and oils (e.g. BS1000®, Hasten™, D-C-Trate®).

8. Soluble fertilisers.

Cleaning and decontaminating boomsprays

Cleaning and decontaminating spray equipment for herbicide application is essential. Many crops and pastures have been severely damaged or destroyed by failing to ensure that spray equipment was thoroughly cleaned before use.

With the advent of crops such as canola and pulse crops in the rotation, and with more emphasis on legume-based pastures, decontaminating spray units must be carried out to ensure that there is no possibility of crop or pasture damage.

Product labels usually detail decontamination and cleaning procedures for each product.

( ) × 3.6( ) = ............... km/hr

‘3.6’ in the calculation is a conversion factor to convert metres to kilometres (metres ÷ 1000) and seconds to hours(seconds ÷ 3600): D/1000 ÷ S/3600 = D/1000 × 3600/S = D/S × 3600/100 = D/S × 3.6.* To calculate your actual ground speed:• Measure a set distance, for example 100 metres.• Make sure that the spraying conditions are like those in the area that you will be spraying.• Record how long it takes using the appropriate gears and revs. Now you can calculate the water application rate, how much chemical you will need to mix in each tank and how many tank loads you will need to do the whole job. Follow the steps below:1. Copy the answers you worked out on the previous page into the boxes below. You will need these numbers to do

the calculations on this page. (The numbers in black circles (e.g. ) tell you the step where the answer is on the

previous page.

2. Work out the water application rate by using the numbers you have recorded above. Put these numbers in the correct place in the calculation below.

Water application rate

‘600’ in the calculation is a conversion factor to convert litres per minute to litres per hour (minutes × 60), and kilometres to metres (km × 1000), then square metres (m × km × 1000 = m2) to hectares (m2 ÷ 10000):60 ÷ 1000/10000 = 60 ÷ 1/10 = 60 × 10 = 600.

Does this water application rate meet the chemical label requirements? (See Part B above) Yes No

If not, how could you change this rate to meet this requirement?

3. Now that you know the water application rate you can calculate how much chemical you need to mix in each tank.

Managing your legal responsibilities in applying pesticides

Pesticides ActThe Pesticides Act 1999 is the primary legislative instrument controlling the use of pesticides in NSW and is administered by the Environment Protection Authority (EPA). The underlying principle of the Pesticides Act is that pesticides must only be used for the purpose described on the product label and all the instructions on the label must be followed. Consequently, all label directions must be read by, or explained to, the user before each use of the pesticide.

All pesticide users should take reasonable care to protect their own health and the health of others when using a pesticide. They should also make every reasonable attempt to prevent damage occurring from the use of a pesticide, such as off-target drift onto sensitive areas or harm to endangered or protected species.

A Regulation was gazetted in 2009 renewing the requirement for all commercial pesticide users, i.e. all farmers and spray contractors, to keep records of their pesticide application.

While no set form has to be used, records must include:• the full product name• a description of the crop or situation• the rate of application and quantity applied• a description of the equipment used• the address of the property, identification of the

area treated and order of paddocks treated• the date and time of the application (including start

and finish)• the name, address, and contact details of the

applicator and of the employer or owner if an employee or contractor is the applicator

• the estimated wind speed and direction (including any significant changes during application)

• other weather conditions specified on label as being relevant (e.g. temperature, rainfall, relative humidity).

A form that captures all the information required by the Regulation, together with notes on how to fill it in, is included in this guide.

A self-carboning record book is available from DPI. Call 1800 138 351 to order your copy of the SMARTtrain spray record book ($10.00). Other websites, including Spraywise, have record forms or you can download an app from Farming with apps (www.farmingwithapps.com/). More information on your spray record responsibilities is available on the Environment Protection Authority website (epa.nsw.gov.au/pesticides/pestrecords.htm). The EPA also has a spray record form (epa.nsw.gov.au/resources/pesticides/130814PestFmEg.pdf) you can download and use.

Records must be made within 24 hours of application, be made in legible English, and kept for three years.

The 2009 Regulation requires all commercial pesticide users to be trained in pesticide application.

Trained aerial applicators, pest control operators and fumigators are recognised as satisfying the requirements of the Regulation. Apart from these groups, all commercial users must have a prescribed qualification. Only domestic use, such as home gardens, is excluded, provided the pesticide is a specific domestic/home garden product. Covered by the Regulation is pest control by/on:• public authorities, e.g. State Rail• golf courses, sporting fields and bowling greens• agricultural, horticultural, aquacultural and forestry

operations• businesses, educational institutions, and hospitals.The minimum prescribed training qualification is the AQF2 unit of competency, ‘Apply chemicals under supervision’, although owner-applicators are encouraged to train and be assessed in the two higher AQF3 competencies, ‘Prepare and apply chemicals’ and ‘Transport, handle and store chemicals’.

Growers are recommended to undertake the SMARTtrain course, Chemical Application, or the standard ChemCert course, both of which cover the higher AQF3 competencies. For growers with literacy and/or numeracy problems, the lower level AQF2 competency will provide a minimum qualification that satisfies the Regulation.

Hazardous Chemicals legislationMany registered pesticides are classified as hazardous chemicals. Even those that are not classified as hazardous pose some risk to the health of those who use them or are exposed to them.

The Work Health and Safety Act 2011 (WHS), and the Hazardous Chemical section of the Work Health and Safety Regulation 2011, detail legal requirements of suppliers, workers and persons conducting businesses or undertakings in the workplace for hazardous chemicals management. The Act and accompanying Regulation are intended to protect workers from both the short- and long-term health effects of exposure to hazardous chemicals and to improve current health and safety practices by:• providing health and safety information to

workers (including a list or register of all hazardous chemicals and an SDS (Safety Data Sheet) for each hazardous chemical)

• consultation with, and training, workers• minimising the risks from hazardous chemicals

• health surveillance (if warranted by the risk assessment in respect of organophosphates).

Both storage and use are covered by the WHS legislation.

Storage limits have changed. Premises storing large quantities require both the storage shed and the entrances to the premises to display placards. If very large quantities are stored – which would be rare on-farm – a manifest, site plan and written emergency plan are required. Consult your local WorkCover office for advice.

WorkCover NSW’s Code of Practice for safely using and storing chemicals (including pesticides and herbicides) in agriculture is an approved industry code of practice and provides practical guidance for farm chemical users to comply with this legislation.

How to complete your Pesticide Application Record SheetThe application record form includes more than the Pesticide Regulation requires, so compulsory information is in italics below each heading.

Property/holding:Attaching a property map or line drawing, showing adjoining sensitive areas, with paddocks and other features clearly identified can be helpful.

Fill in the residential address.

Applicator details:The person applying the pesticide must fill in their contact details. If the applicator is not the owner, e.g. a contractor or employee, then the owner’s details must also be completed. In the case of a contractor, one copy of the record should be kept by the applicator and another given to the owner.

Sensitive area identification:If there are sensitive areas, either on the property or on land adjoining, these should be identified in advance, and marked on the sensitive areas diagram, together with any precautions or special instructions. When using a contractor or giving the job to an employee, this section should be filled in and given to the person doing the application BEFORE the job starts. The property map with sensitive areas marked should be shown to them, and the job fully discussed.

Paddock identification:Identify the paddocks/blocks and order of treatment (if there is more than one) in the ‘paddock’ row of the form. This should be filled in before starting application, along with the residential address. If using a contractor or employee, this information should also be given to them BEFORE they start the job. Applicators using GPS systems could include a GPS reading as well as the paddock number/name.

Crop/animal identification:The left hand side of the Crop/situation section of the table is for crops, pastures and plants (non-crop, e.g.

bushland and fallow), the right hand side for animals. As a minimum, identify the host (crop/situation) and the weed. It would be helpful to provide as much detail about the weed as possible, e.g. 4 leaf. Additional details such as crop variety and growth stage are often important for quality assurance schemes, but could also be necessary to positively identify the area treated as required by the Regulation.

Product details:Transcribe the product name and rate or dose from the label, including all products and additives included in tank mixes. If the use pattern is on a permit, include the permit number, expiry date and label details. A permit rate or dose might vary from the label. Water rate might come from the label, or from your standard practice or calibration. The total litres (L) or kilograms (kg) can be calculated when the application is finished.

Withholding periods: (WHP)Labels often have a number of different withholding periods. They may be different harvest WHP for different crops, grazing WHP or Export Slaughter Interval (ESI). All WHP’s are the minimum number of days after treatment before harvest, grazing or livestock slaughter for export markets can take place.

Equipment details:As a minimum, you have to fill in what equipment you used. Specifying the setting used for the application can help positive identification, e.g. nozzle type and angle; pressure. The nozzle type will usually include the angle. With pressure, the reading should be as close to the nozzle as possible. Other details e.g. date of calibration and water quality, are useful as a reminder for future use, or as a check on your set-up should you have a treatment failure. Water quality is important for herbicide efficacy. At the most basic level, water quality can be described in terms of its source, e.g. rainwater, dam water, bore water.

Weather:As a minimum, you have to record wind speed and direction. It is better to measure with instruments than estimate. Record any changes during application.

You must also record the time of day when you started, and the time when you finished.

You will need to record weather information for all equipment that distributes pesticide through the air.

Rainfall should be recorded for the 24 hours before and the 24 hours after application, unless a different figure is given in the restraints or critical comments sections of the label. Rainfall before or after application can affect efficacy.

Temperature and relative humidity should also be recorded, particularly if either or both are referred to in the restraints or critical comments sections of the label. Temperature and relative humidity can affect efficacy, increase the risk of off-target drift or could damage the host (e.g. phytotoxicity) or a combination of all three.

Reducing herbicide spray driftSpraying during the night and early morning is common, especially for reaching the target and to minimise the amount reaching off-target areas. This results in:

• maximum pesticide effectiveness• reduced damage and/or contamination to off-

target crops and areas.In areas where a range of agricultural enterprises co-exist, conflicts can arise, particularly from pesticide use. All pesticides are capable of drift.

People have a moral and legal responsibility to prevent pesticides from drifting and contaminating or damaging neighbours’ crops and sensitive areas.

Some labels now carry spray drift management instructions including buffer zones. Read and follow all label instructions.

How to minimise spray drift problems

Before spraying• Always check for susceptible crops in the area,

e.g. broad leaf crops such as grape vines, cotton, oilseeds or pulse crops if using a broadleaf herbicide, and sensitive areas such as houses, schools and riparian areas.

• Notify neighbours of your spraying intentions.• Under the Records Regulation of the Pesticides

Act it is essential that weather and relevant spray details are recorded. Forms are available from the DPI website (www.dpi.nsw.gov.au/agriculture/farm/chemicals/general/records).

During spraying• Always monitor meteorological conditions carefully

and understand their effect on drift hazard.• Do not spray if conditions are not suitable, and

stop spraying if conditions change and become unsuitable.

• Record weather conditions (especially temperature and relative humidity), wind speed and direction, herbicide and water rates, and operating details for each paddock.

• Supervise all spraying, even when a contractor is employed. Provide a map marking the areas to be sprayed, buffers to be observed, sensitive crops and areas.

• Spray when temperature is less than 28 °C.• Minimise spray release height. (Lowest possible

boom height).• Use the largest droplets that will give adequate

spray coverage. Where droplet size is mentioned on

the label, follow the label instructions.• Always use the least-volatile formulation of

herbicide available.• Maintain a down-wind buffer that could be in-crop,

e.g. keep a boom width from the downwind edge of the field. Where buffer zones are mentioned on the label, follow label instructions.

• If sensitive crops are in the area, use the least damaging herbicide.

How many types of drift are there?Sprayed herbicides can drift as droplets, as vapours or as particles.

Droplet drift is the easiest to control because, under good spraying conditions, droplets are carried down by air turbulence and gravity to collect on plant surfaces. Droplet drift is the most common cause of off-target damage from herbicide application. For example, spraying fallows with glyphosate under the wrong conditions often leads to severe damage to nearby establishing crops.

Particle drift occurs when water and other herbicide carriers evaporate quickly from the droplet leaving tiny particles of concentrated herbicide. This can occur with herbicide formulations other than esters. Instances of this form of drift have damaged susceptible crops up to 30 km from the source.

Vapour drift is confined to volatile herbicides such as 2,4-D ester. Vapours can arise directly from the spray or evaporation from the herbicide-sprayed surfaces. Use of 2,4-D ester in summer can lead to vapour drift damage of highly susceptible crops such as tomatoes, sunflowers, soybeans, cotton and grapes. This can occur hours after the herbicide has been applied.

Vapours and minute particles float in the airstream and are poorly collected on catching surfaces. They can be carried for many kilometres in thermal updraughts before being deposited.

Sensitive crops may be up to 10,000 times more sensitive than the crop being sprayed. Even small quantities of drifting herbicide can cause severe damage to highly sensitive plants.

What factors affect the risk of herbicide spray drift?Any herbicide can drift. The drift hazard, or off-target potential of a herbicide in a particular situation depends on the following factors:

• Volatility of the formulation applied. Volatility refers to the likelihood that the herbicide will evaporate

Page 32: Weed control in winter crops 2018 - riverina.lls.nsw.gov.au · 5 Using the growth stages of cereal crops to time herbicide applications 6 Using herbicides successfully 6 The Poisons

26 | Greg Brooke and Colin McMaster

and become a gas. Esters volatilise (evaporate) more readily than amine formulations.

• Proximity of crops susceptible to the particular herbicide being applied, and their growth stage. For example, cotton is most sensitive to Group I herbicides in the seedling stage.

• Method of application and equipment used. Aerial application releases spray at ~3 m above the target and uses relatively low application volumes, while ground rigs have lower release heights and generally higher application volumes, and a range of nozzle types. Misters produce large numbers of very fine droplets that use wind to carry them to their target.

• Amount of active ingredient (herbicide) applied – the more herbicide applied per hectare the greater amount available to drift or volatilise.

• Efficiency of droplet capture – bare soil does not have anything to catch drifting droplets compared with crops, erect pasture species and standing stubbles.

• Weather conditions during and shortly after application.

Use a low volatile formulationMany ester formulations are highly volatile when compared with the non-volatile amine, sodium salt and acid formulations. Some low volatile ester formulations could have a proportion of high volatile esters present, so caution should be exercised when using these products.

The compromise between minimising drift and achieving ideal coverageA significant part of minimising spray drift is equipment selected to reduce the number of small droplets produced. However, this in turn can affect target coverage, and therefore the possible effectiveness of the pesticide application.

This aspect of spraying needs to be carefully considered when planning to spray.

As the number of smaller droplets decreases, so does the coverage of the spray. The water rate might need to be increased to compensate for coverage.

Reduce spray release height• Operate the boom at the minimum practical height.

Drift hazard doubles as nozzle height doubles. If possible, angle nozzles forward 30° to allow a lower boom height with double overlap. Lower heights however, can lead to more striping, as the boom sways and dips below the optimum height.

• 110° nozzles produce a higher percentage of fine droplets than 80° nozzles. However, they allow a lower boom height while maintaining the required double overlap.

• Operate within the pressure range recommended by the nozzle manufacturer. Driftable fine droplet

production increases as the operating pressure is increased. Lower volumes such as 30–40 L/ha produce a higher percentage of fine droplets than higher spray volumes at the same pressure and nozzle design.

Aircraft application has an inherently greater risk than ground rig application due to a number of factors, including lower volume application, small droplet sizes, height of application, and turning and wing-tip vortices. An aircraft should not be used to apply herbicide in areas where highly susceptible crops are growing nearby.

Size of the area treatedWhen large areas are treated, relatively large amounts of active herbicide is applied and off-target risks increase due to the length of time taken to apply the herbicide. Conditions such as temperature, humidity and wind direction can fluctuate during spraying.

Applying volatile formulations to large areas increases the chances of vapour drift damage to susceptible crops and pastures.

What is your ‘capture surface’?Targets vary in their ability to collect or capture spray droplets. Well grown, leafy crops are efficient droplet collectors. Turbulent airflow normally carries spray droplets down into the crop within a very short distance of the nozzle.

Fallow paddocks or seedling crops are poor catching surfaces. Drift hazard is far greater when applying herbicide in these situations or adjacent to these poor capture surfaces.

When assessing drift hazard the type of catching surface between the sprayed area and susceptible crops should always be considered in conjunction with the characteristics of the target area.

Nozzle selection for post-emergent herbicides and fungicides

Overview

Nozzle selection for applying post-emergent herbicides and fungicides to cereals should primarily focus on reducing the risk of spray drift without compromising efficacy. Drift or loss is a significant issue facing the industry and spray applicators not only have a moral but a legal obligation to adopt drift management best practice.Applying fungicides and herbicides in late season requires consideration for coverage and penetration issues that are usually not required for pre-emergent or summer/fallow applications.

Fungi typically target specific plant parts such as stems, leaves, and heads or pods. These locations must be adequately covered by droplets for the fungicide to work, and this requires special approaches regarding what nozzle to use. Likewise,

Page 33: Weed control in winter crops 2018 - riverina.lls.nsw.gov.au · 5 Using the growth stages of cereal crops to time herbicide applications 6 Using herbicides successfully 6 The Poisons

WEED CONTROL IN WINTER CROPS 2018 | 27

some weeds might need to be selectively targeted within the crop canopy, potentially a far trickier proposition than knockdown applications.

For many years the standard maxim was to spray these products with fine droplets because they were assumed to give the best coverage. But after many years of spray application research around the world, the current recommendation is to avoid fine droplets in preference to a coarse, directed spray applied at higher water volumes than what might be considered ‘normal’ application rates.

The problem with fine drops

In principle, fine drops should mean greater coverage, that is if they actually land on the target and don’t blow away or evaporate. However, small droplets travel slowly and have little inertia/momentum so are easily displaced by wind and turbulence.

Incidentally, the logic of increasing the spray pressure to force fine drops into the canopy is wrong. The acceleration of small droplets lasts only milliseconds and has no impact on the overall travel time of the droplet to the target. Spraying at high pressure not only increases the wear rate of nozzles, it also produces finer sprays with a corresponding increase in drift potential.

Coarse droplets are the go

Coarser spray provide just as much coverage as long as water volume is sufficient (>80 L/ha). In terms of coverage, the droplet density (or number of drops/cm) is more important than droplet size, and adequate densities (efficacy) can be achieved with nozzles that produce coarse spray qualities.

Coarser droplets also maintain their original direction of travel for longer and, in the case of TwinJets (or double outlet nozzles), can cover the forward and backward sides of the target more effectively.

What nozzle?

TeeJet recommends 110° TwinJets (or dual pattern nozzles) for both post-emergent herbicides and fungicides. Choices include the Turbo TwinJet (TTJ), the Air Induction Turbo TwinJet (AITTJ) or the Air Induction Dual Pattern AI3070, a nozzle specifically designed for fungicide application in cereal crops. Double outlet nozzle bodies and caps are also available for growers who might want to mount two conventional nozzles on the one nozzle body.

Double outlet nozzle body or cap• If using Turbo TeeJets (TT),

60°, 90° or 120° included angle • Drift Control, drop size,

pressure range – varies

The final choice will depend on the product being applied, travel speeds (or application volume), crop density and the applicator’s pre-spray drift risk assessment (weather conditions, location of susceptible crops etc.).

Conclusions• Use high application volumes

unless the label specifically recommends against it. Higher volumes improve both coverage and spray penetration – the single most important variable for post-emergent herbicides and fungicides.

• Avoid very fine sprays as they can lead to excessive spray drift and evaporation.

• Use TwinJets that produce coarser droplets that maintain their original direction of travel for longer and therefore cover the leading and trailing sides of the target more effectively.

• Always try to select and operate a nozzle around its mid pressure range (e.g. AITTJ60 at 3–4 bar)

As always, any application requirements on the product label must be adhered to. Source: Peter Alexander, TeeJet Australasia Pty Ltd.

Weather conditions to watch out forMidday turbulence• Updraughts during the heat of the day cause rapidly

shifting wind directions. Spraying should usually stop by 11.00 am during the summer months.

High temperatures• Avoid spraying when temperatures exceed 28 °C.

Humidity• Avoid spraying under low relative humidity conditions

i.e. when Delta T (the difference between wet and dry thermometers) exceeds 10 °C. Spraying when Delta T is between 8–10 °C is considered high risk.

• High humidity extends droplet life and can greatly increase the drift hazard from fine droplets under inversion conditions. This results from an increased life of droplets smaller than 100 microns.

Wind• Avoid spraying under calm conditions.• Ideal safe wind speed is 7–10 km an hour. Leaves

and twigs are in constant motion – a light breeze.• 11–14 kph (moderate breeze) is suitable for spraying if

using low drift nozzles or higher volumes application (80–120 L/ha). Small branches move, dust is raised and loose paper moving – a moderate breeze.

Surface inversionsWhat are surface inversions?Surface inversions are layers of the atmosphere at the earth’s surface in which temperature increases with height. This is the opposite (inverse) of the normal temperature decrease with height.

Hazards of surface inversionsSurface inversions strongly suppress airborne pesticide (and similar) dispersion. Surface inversions can cause airborne pesticides to:• remain at high concentrations for long periods over

and close to the target• travel close to the surface for many kilometres in

light breezes• move downslope and concentrate into low-lying

regions• be transported often in unpredictable directions.

Radiation inversions – the most hazardousSurface inversions usually begin to occur near sunset after heat energy through infrared radiation upward into space causes the ground to cool. That radiation passes through clear air with little effect. As the ground cools, the air in contact with the ground begins to cool directly through conduction leading to the lowest layer of air being cooler than higher layers. This is referred to as radiation cooling.

Inversions caused by radiation cooling – called radiation inversions – are the most hazardous to pesticide applications because they are the most likely to severely restrict dispersion and promote transport (drift) at high concentrations of the airborne pesticides.

Radiation inversions occur most nights. Only when winds are strong enough to completely mix the lowest layers of the atmosphere and/or cloud cover severely restricts surface heating and cooling is there a chance that surface radiation inversions won’t form overnight.

Radiation inversions also form over sloping terrain when air in contact with the ground is cooled by terrestrial radiation. The cooled layer remains quite shallow over the slope and is typically only 2 –10 m deep, because gravity continually pulls it downward causing

drainage winds. Drainage-wind advection (horizontal convection) of cool air away from the slope and over or into lower lying regions can initiate a drainage inversion or intensify an existing radiation inversion. Drainage inversions, once formed, have similar attributes to radiation inversions. Drainage winds can transport airborne pesticides long distances downhill, over flat terrain toward the lowest lying regions and into valleys.

Radiation and drainage inversions have caused substantial damage in the northern river valleys to cotton crops and to vineyards in the Murray Valley.

Radiation and drainage inversions typically begin in the evening at about sunset as the ground surface cools and the air in contact with the surface loses sufficient heat by conduction to become colder than the air immediately above. With continued overnight cooling, inversions usually intensify and deepen up to the time of the overnight minimum temperature.

How to anticipate and recognise radiation inversionsThe potential for inversions to occur and to adversely hold high concentrations of airborne pesticides near the surface should always be anticipated between sunset and up to an hour or two after sunrise; unless one or more of the following conditions occur: • There is continuous overcast, low and heavy cloud. • There is continuous rain.• Wind speed remains above 11 km/hr for the whole

period between sunset and sunrise. Be mindful that established inversions can sometimes still occur when winds are in excess of 11 km/hr.

Where to find helpful meteorological informationReal time data needs to be collected in the paddock at the time of spraying. This can be done with:

» Handheld units that measure temperature, Delta T and wind speed

» on-farm weather stations – some can now be accessed by mobile phone.

Hourly data• Forecasts are available from a number of websites

for Delta T, wind speed etc. usually in three-hour blocks.

Hourly data from the Bureau of Meteorology (BOM) weather stations including temperature, Delta T, wind speed and direction is available for the previous 72 hours from BOM. This data can help in planning spray activities and is useful for developing an understanding of the current daily patterns of meteorological conditions.

Meteograms™ Meteograms™ provide seven-day forecasts of:

• Temperature• relative humidity• Delta T• Rainfall• wind speed• wind direction.Meteograms™ are very helpful in planning spray programs for periods of lowest drift risk and highest pesticide efficacy.

Meteograms™ are mostly available by subscription. Some examples can be found at Weatherwise (http://www.weatherzone.com.au/models/meteogramdrill.jsp), or Spraywise (www.spraywisedecisions.com.au).

Night sprayingSpraying during the night and early morning is common, especially during the warmer summer months where controlling fallow weeds is an important agronomic practice. Spraying at night increased with the introduction of GPS guidance. The main reason for night spraying is because, in many cases, Delta T conditions less than 8–10 are more common at night or in the early part of the morning, and the risk of physical drift from high wind is lower.

However, the risk of inversions is nearly always greater at night or in the early morning. Spraying during inversion conditions has resulted in large off-target damage in recent seasons, particularly to sensitive crops such as cotton and grapes.

Important considerations when spraying at night• As a result of the APVMA’s spray drift initiative,

labels will increasingly include the restraint, ‘DO NOT apply during surface temperature inversions conditions at the application site.’ Any restraint is an absolute prohibition. Since surface inversion conditions are prevalent at night, night spraying should be avoided unless the applicator can demonstrate an inversion was not present.

• Plan ahead by checking local forecast conditions and meteograms.

• Continuously check for inversions before and during spraying. If they are present DO NOT spray. Observe dust habits behind ground rigs and/or use smoke generators to help identify inversion conditions.

• Only spray with nozzles that produce coarse or very coarse droplets. This may mean spraying slower rather than faster. Coarse droplets will still provide effective control when spraying summer weeds.

• Use adjuvants that minimise fine droplets.• Ensure boom height is not operated higher than

necessary.• Be aware of local off target risks, such as sensitive

crops etc.Night spraying therefore carries some inherently high risks that spray applicators should be continuously monitoring and managing.

• Unique pre-plant incorporated by sowing (IBS) use patterns in imidazolinone herbicide tolerant barley, wheat (single gene) and canola

• Pre-plant (IBS) application resulting in earlier weed control reducing crop competition at emergence and maximising yield potential

• Compatible with key pre-emergent and knockdown herbicides

• Also registered for post-emergent use in imidazolinone tolerant canola and single gene wheat

• Registered for post-emergent application to imidazolinone herbicide tolerant barley and canola

• Offers unsurpassed foliar uptake on key grass and broadleaf weeds and greater flexibility with future cropping

WEED CONTROL IN WINTER CROPS 2018 | 59

Herbicide resistance management

Defining herbicide resistanceHerbicide resistance is the inherent ability of a weed to survive a herbicide rate that would normally control it. This is not the same phenomena as poor herbicide performance.

Why it is a problem?

If herbicide resistance develops, herbicides from different chemical ‘groups’ or different control methods will have to be used to control the weed. These options may be more expensive or less effective. Once developed, herbicide resistance will persist for many years.

Understanding herbicides

Herbicides act by interfering with specific processes in plants. This is known as the herbicides ‘mode of action’ (MOA).

Watch your paddocks• Keep accurate records.• Monitor weed populations and record results of

herbicides used.• If herbicide resistance is suspected, prevent weed

seed set.• If a herbicide does not work, find out why.• Check that weed survival is not due to spraying

error.• Conduct your own paddock tests to confirm

herbicide failure and what herbicides are still effective.

• Have a herbicide resistance test carried out on seed from suspected plants testing for resistance to other herbicide (MOA) groups.

• Do not introduce or spread resistant weeds in contaminated grain or hay.

• Resistance can develop from fence lines and irrigation channels. Closely monitor and test for resistance in these areas.

Herbicide resistance testing

The best investment a grain grower can make is to test any weedy outbreak that is suspected of having herbicide resistance. It provides valuable information about the herbicides that don’t work, but more importantly the herbicides that are effective. An approximate cost of a broad spectrum test is $600 to $700. This would include at least 6–7 herbicides. This cost is insignificant compared with a widespread spray failure over 200 hectares that costs $30/ha in herbicides; totalling $6,000 in wasted herbicide, not including crop yield losses and the blow out in weed seed for future years.

There are two types of tests available; a quick test and a seed test. The quick test involves live seedlings being sent away for re-potting and spraying. Once the plants have fully recovered they are sprayed with herbicides of your choice. Results are usually reported between four and eight weeks after arrival at the testing facility. This is usually too late to enable re-treatment of the ‘suspect’ patches, but does provide early knowledge about the nature of the problem and what is likely to work in the future. One disadvantage of the quick test is it cannot test for pre-emergence herbicides, as the plants are already emerged.

A seed test requires seed to be sent and often involves breaking seed dormancy upon arrival. It is a useful test if you require herbicide resistance testing of pre-emergence herbicides. The turnover time is approximately four months and results are usually sent to clients in April (if seed was sent in December). This will allow ample time to decide what herbicides to use for the next crop.

Which herbicides should I test?

Ideally test any and every herbicide that you might wish to use in the future for the target weed species (there are a few exceptions – read on). Any application of herbicide that results in survivors setting seed will classify as some selection pressure for resistance. Be sure to include some herbicides that you have not yet used.

There are two reasons for this; firstly you may have developed cross resistance, i.e. confirmed resistance without a history of it being used, or new crop rotations in the future will allow the use of new herbicide groups. A good mixture of ‘fop’ and ‘dim’ herbicides is recommended and if you intend to use Axial® (‘den’ herbicide) include it. If ARG (annual ryegrass) is your key weed and you grow wheat, pulse or a Clearfield crop it is worthwhile including a sulfonylurea herbicide (e.g. Tackle or Associate®) and an imidazolinone herbicide (e.g. Spinnaker®, Raptor®). Testing for trifluralin or Avadex® resistance would only be required if you have a history of using them for at least 10 applications in that paddock of concern.

Lastly, never under-estimate the number of glyphosate applications these weeds could have received. As a cautious measure, including glyphosate as a test herbicide is a wise choice, especially for ARG.

There are many cases of glyphosate resistant ARG in NSW. Although there is a chance of discovering glyphosate resistant weeds, resistance testing may discover concerning or low levels of survival following glyphosate application. If this occurs, it maybe the precursor for the development of glyphosate resistance.

Rotate herbicide groups • Avoid spraying dense weed infestations

Aim to:• Reduce weed numbers by preventing seed set.• Avoid spraying dense weed infestations and begin a

cropping phase with low weed numbers.• Use as many different control options (chemical and

non-chemical) as possible in both crop and pasture phases.

When using herbicides:• Rotate herbicides from different groups.• Reduce reliance on high-risk herbicides (Groups A and B).• Make every herbicide application count – use the rate

that kills.• The ‘double knock’ herbicide option; before sowing –

glyphosate followed by paraquat + diquat.

Surveys for herbicide resistant grass weeds in southern Australia

Key points• Herbicide resistance is common in annual ryegrass

in most cropping regions of southern Australia• Trifluralin and Clethodim resistance are increasing• Resistance to herbicides is also present in wild oats

and brome grass• Glyphosate resistance occurs where there is

intensive use of glyphosate and few or no other weed control tactics

• Some alternatives to glyphosate will control glyphosate-resistant annual ryegrass on fence lines.

Random surveys of weed populations across southern Australia have identified considerable levels of herbicide resistance in annual ryegrass across southern Australia. There are variations across regions, with trifluralin beginning to emerge as an issue (Table 1). These regional differences reflect differences in cropping practices and hence herbicide use patterns. Of particular concern is the increase in

clethodim (Select) resistance and was reported in 13% of samples (Table 3). More emphasis should be aimed at crop competition andHR annual ryegrass weed seed capture/destruction at harvest to maintain or extend the life of clethodim and other effective post-emergence herbicides.

The incidence of multiple resistance within annual ryegrass is concerning. Approximatley 70% of samples tested had resistance to at least 2 herbicide mode of actions. In some rare cases resistance to 4 herbicide groups has developed in 2013 (Table 2).

Wild oats management previously relied on post-emergence herbicides. Consequently there is a high frequency of resistance to ‘fops’, ‘dims’, and ‘den’ chemistry (Table 4). More pre-emergence herbicides are being use in NSW cropping systems to combat these issues with wild oats. Effective crop competition in combination with effective pre- and post-emergence herbicide should prolong the effective life of these herbicides.

Glyphosate resistance in annual ryegrassThere are now 678 confirmed sites with glyphosate resistant annual ryegrass in Australia. These come from four states and a variety of situations (Table 5). Glyphosate resistant annual ryegrass occurs when populations are treated intensively with glyphosate, where no other herbicides are applied and where there is little or no tillage. Relying solely on glyphosate for weed control is the greatest risk factor for glyphosate resistant weeds.

Herbicide resistance in winter broad-leaf species is steadily increasing. In 2013, a population of wild radish was confirmed resistant to 2,4-D amine (Group I) in central NSW. There are other populations of this weed resistant to Group B in southern NSW. Fleabane is glyphosate resistant and is located over all of NSW due to its wind-borne seed (see Table 6). Another weed spread by wind, sowthistle, has been reported as glyphosate resistant in 2014 and is currently confined to northern NSW. However, Group B resistance is present in this species. Two brassica species, Indian hedge mustard and charlock are reported to have Group B resistance in NSW.

Pulse crop growth stagesAll pulse species have the same basic structure based on a main stem, which can be divided into basic units known as nodes. Two scale leaves appear first and the nodes, where they occur, are not counted as

true nodes. A node is made up of a petiole that has stipules where it joins the stem, and leaflets along its length. In some species it terminates in a simple or more complex tendril.

Stipule• in pairs• each side of the leaf axis where it

joins the stem• smaller than leaflets• size varies slightly with variety

top of plant• shape varies with variety

Table 34. Herbicides for weed control for field pea – Early post-emergence (continued, page 2 of 2)

i Add 125–150 mL Agility®. g May delay crop maturity. Apply early post‑emergence after the 3rd node

stage and before the start of flowering. Weeds 4–6 leaf stage.h Apply only on varieties Alma, Banzer, Dun, Dundale, Glenroy, Laura and

Wirrega. Add BS1000® or equivalent at 250 mL/100 L water. Small weeds. See Table 2 on page 8 for plantback requirements.

j Do not add any spray additives. May cause yellowing, reduced height and delayed flowering.

k Do not tank mix with other herbicides for field pea. Check label for suitable rate and influence of variety and disease. Best results with moist soil surface. Two sunny days before spraying improves crop tolerance. See label.

l Not on Wirrega field pea post‑emergent. Use higher rate on larger weeds.; Apply before crop canopy obscures weeds. Caution on alkaline soils.(S) Suppression only.

Sensitivity to herbicides in winter crop varieties

Some winter crop varieties are more susceptible to damage than others from certain herbicides. Small yield reductions in sensitive varieties caused by herbicide damage might not be easily detected, but over large areas can be costly.

Symptoms of crop damage from herbicides do not always lead to loss of yield but it is still important to recognise these signs to try to prevent future problems occurring.

For descriptions and pictures of herbicide injury see Field crop herbicide injury: the Ute Guide available from the GRDC Bookshop (https://grdc.com.au/resources-and-publications/all-publications/link.aspx).

In NSW, winter crop varieties are tested for herbicide tolerance at the Wagga Wagga Agricultural Institute. Testing is supported by the Grains Research and Development Corporation and is part of a National Herbicide Tolerance Program.

Results from the NSW program and other states are available from the National Variety Trials website (www.nvtonline.com.au).

Tolerance testing methodologyTrial sites are chosen and managed to ensure:

• Minimal weed competition so that herbicide responses are due to varietal sensitivity to herbicides rather from weed competition.

• Representative and uniform soil types within each Australian region.

• Trial assessments include:• Visual observations two to three weeks after

herbicide application and again (2–3 weeks later) or as appropriate.

• Normalised Difference Vegetative Index (NDVI) measurements using a Greenseeker™ approximately 21–30 days after treatment.

• Grain yield and climatic data.

Preliminary evaluation (PE) trialsWheat and barley lines continuing beyond the first year of National Variety Trials (NVT) are automatically eligible for inclusion in the first stage of cultivar tolerance evaluation, namely Preliminary Evaluation (PE) Trials. Within these trials, commonly used and often damaging herbicides/ tank mixes are applied at high rates in order to highlight cultivar sensitivities.

Within PE trials:• treatments are evaluated within very small plot or

single row experiments• herbicides/tank mixes are selected according to the

Herbicide Selection Protocol• each cultivar × herbicide combination is evaluated

across two seasons, unless the cultivar is discarded by the breeder after year one

• any herbicide/cultivar combination that incurs a significant yield penalty in at least one year of trial is progressed to Advanced Evaluation (AE) trials

• if a herbicide/cultivar combination does not incur yield loss in either of the two seasons of PE testing it is given a safe rating.

Advanced evaluation (AE) trialsThis second stage of evaluation aims to validate and supplement results from PE trials with data on tolerance and safety margins gathered from more detailed experiments.

Within AE trials:• Treatments are evaluated within replicated, large

plot, split strip plot designed experiments.• Only those herbicide/cultivar combinations which

were found damaging within PE trials are evaluated.• Herbicides are applied at the recommended rate

and higher to obtain data on both tolerance at label rates, and safety margin.

• All treatments (cultivar and herbicide) are evaluated across a minimum of two seasons to account for seasonal variations in cultivar response.

Note: Within the pulse, oat and triticale species only AE trials are implemented. Within these trials cultivar selection is based on collaboration with breeders, and herbicide selection is based on discussions with regional agronomists, farmers and herbicide manufacturers.

Herbicide selection protocolIn making the choice of herbicides used in trials, consideration is given to:• existing and widely used herbicides/tank mixtures

with known variation in crop/cultivar safety• new or previously untested herbicides. New

chemistry trials allow for evaluation of a group of commonly grown varieties, to be tested against new or upcoming herbicides. If a new herbicide is found to be damaging AND there is expected to be significant farmer use, the herbicide is progressed to preliminary evaluation trials.

Table 47. Winter crop herbicide/insecticide/fungicide compatibilities (page 1 of 4)This chart is a guide only. Read both product labels if using a mixture.

C = Compatible. N = Not compatible. Where there is a blank compatibility is not known, contact the manufacturer. Compatibility is dependent upon use pattern (both crop and weeds), rate, surfactant/compatibility agent and temperature. Water quality also affects compatibility. Mixtures generally require greater agitation. Mixing more than two chemicals affects compatibility and is not recommended. Read the compatibility and crop safety sections of both labels before mixing. Mixing chemicals is at the user’s own risk.* WG formulations also available; check labels for compatibilities. ** Other formulations also available; check labels for compatibilities. *** DO NOT mix with selective grass herbicides. **** Check label for compatible mixing rates and effect on weeds.

C = Compatible. N = Not compatible. Where there is a blank compatibility is not known, contact the manufacturer. Compatibility is dependent upon use pattern (both crop and weeds), rate, surfactant/compatibility agent and temperature. Water quality also affects compatibility. Mixtures generally require greater agitation. Mixing more than two chemicals affects compatibility and is not recommended. Read the compatibility and crop safety sections of both labels before mixing. Mixing chemicals is at the user’s own risk.* WG formulations also available; check labels for compatibilities. ** Other formulations also available; check labels for compatibilities. *** DO NOT mix with selective grass herbicides. **** Check label for compatible mixing rates and effect on weeds.

Physically compatible. The addition of Prosaro® to Associate® increased crop effects although effects were generally transient and crops recovered. This was done with the addition of Hasten™ adjuvant. The use of a non‑ionic surfactant should improve crop safety although the rate required (0.25%) is higher than usually recommended for use with Associate®.

Physically compatible. Limited data but good crop safety indicated. Use Hasten™ 1% or an alternative crop oil that is recommended for use with both products. –

Where there is a blank compatibility is not known, contact the manufacturer. Compatibility is dependent upon use pattern, rates, surfactants, compatibility agents, temperature and water quality. Mixtures generally require constant agitation. Mixing more than two products is not recommended. This chart only indicates which chemicals are compatible in mixtures at the time of compilation March 2012. Read the compatibility and crop safety sections of all labels before mixing. Mixing chemicals is at the user’s own risk. See Tips for tankmixing herbicides on page 18.Three‑way mixes can cause compatibility problems in some instances. Important to read critical comments on technical sheets and labels as some rates can cause an adverse crop effect. Product compatibility is sourced from technical notes and labels of the fungicide maufacturer. Both products and companies should be consulted prior to undertaking a tank mix. This chart is for wheat, however individual wheat varieties will need to be checked for suitability for use with any particular herbicide or fungicide listed here.*Tordon 75‑D" has been superseded by "FallowBoss Tordon" 300 g/L 2, 4‑D (present as triisopropanolamine salt) + 75 g/L picloram (present as triisopropanolamine salt) + 7.5 g/L aminopyralid (present as triisopropanolamine salt) ‑ Dow AgroSciences. Compatibilities should be similar to Tordon 75‑D.

In many cases it is useful to mix a herbicide and fungicide together to save on further application passes within a paddock. This has been more common in recent years with less varietal resistance to stripe rust. Mixing herbicides and fungicides whilst practical, can be risky. Many products may be Physically compatible, however interactions may occur between the herbicide and the fungicide which may reduce the efficacy of either or both products. Crop damage may also be greater when mixing herbicides and fungicides. An adjuvant recommended for one product in a tank mix may have an adverse effect on the other product. The same is true of water quality where solubility for one product might be quite different for the other.Whilst this table provides the best available information regarding common herbicide and fungicide mixtures, always consult with your advisor and product manufacturers before tankmixing herbicides with fungicides, and check for any updated technical information on such mixes.
