DIRECTIONS FOR USEIMPORTANT: This information is approved as part of the Product Label. All instructions within thissection must be read carefully in order to obtain safe and successful use of this product.

WARNINGSEXTREME CARE SHOULD BE TAKEN TO AVOID SPRAY DRIFT AS THIS CAN SEVERLYDAMAGE OR DESTROY NEIGHBOURING CROPS AND PLANTS.

DO NOT MIX, STORE OR APPLY PITCH IN GALVANISED OR UNLINED STEEL CONTAINERSOR SPRAY TANKS.

DO NOT leave spray mixtures in tank for long periods and make sure tanks are WELL VENTED.

RESTRICTIONSA period of at least six hours and preferably 24 hours rainfree must follow spraying.

DO NOT spray onto weeds which are naturally senescent, or where growth is impaired bydrought, high temperatures, a covering of dust, flooding or frost at, or immediately afterapplication, otherwise poor control may result.

DO NOT spray in windy conditions as drift onto desired crops or vegetation could severelydamage or destroy them.

As PITCH takes a few days to fully translocate throughout a weed, applications of lime, fertiliser,farmyard manure and pesticides should be made five days or more AFTER application of thisproduct.

After application, large concentrations of decaying foliage, stolons, roots or rhizomes should bedispersed or buried by thorough cultivation before crop drilling.

WEEDS CONTROLLEDPITCH is a foliar acting herbicide which controls annual and perennial grasses and mostbroadleaved weeds when used as directed. It is translocated from treated vegetative growth tounderground roots, rhizomes or stolons.

It is important that all weeds are at the correct growth stage when treated, otherwise some re-growth may occur and this will need re-treatment.

Annual grasses and broadleaved weeds should have at least 5 cm of leaf, or two expanded trueleaves, respectively.

PERENNIAL GRASS WEEDS MUST HAVE A FULL EMERGENCE OF HEALTHY, GREEN LEAFWHICH IS GROWING ACTIVELY AT THE TIME OF APPLICATION. COMMON COUCHREACHES THE SUSCEPTIBLE STAGE OF GROWTH WHEN TILLERING AND NEW RHIZOMEGROWTH COMMENCE WHICH USUALLY OCCURS WHEN PLANTS HAVE FOUR TO FIVELEAVES EACH WITH 10–15 CM OF NEW GROWTH.

THE MAJORITY OF PERENNIAL BROADLEAVED WEEDS ARE MOST SUSCEPTIBLE IFTREATED WHEN THEY ARE GROWING ACTIVELY AND AT, OR NEAR, FLOWERING STAGE.

ANNUAL WEEDS SHOULD BE GROWING ACTIVELY, WITH GRASSES HAVING AT LEAST 5 CM OF LEAF AND BROADLEAVED WEEDS AT LEAST TWO EXPANDED TRUE LEAVES WHEN SPRAYED.

IN SET-ASIDE, annual grasses are best treated at full ear emergence, or before stemelongation. Application during stem extension phase of annual grasses e.g. Blackgrass andBrome species on set-aside between the end April and end May may result in poor control andrequire re-treatment.

BRACKEN should be treated after frond tips are unfurled, but pre-senescence.

This product will not give an acceptable level of control of Horsetails (Equisetum arvense) –repeat treatment will be necessary.

Weeds become less susceptible to PITCH when their growth is restricted by natural senescenceor by drought, frost, high temperature, a covering of dust or flooding. Reduced control willresult if such conditions occur at, or immediately after, spraying.

BREAKDOWN AND FOLLOWING CROPSUpon soil adsorption the herbicidal properties of PITCH are lost permitting the drilling of crops48 hours after application.

Occasionally, a slight check to crop growth may occur, particularly after direct drilling, whencrop seeds germinate amongst a mass of decaying foliage, stolons, rhizomes or roots.Thorough cultivations are necessary to disperse or bury the decaying organic matter.Consolidate loose soils and ensure crops are adequately fertilized and appropriate measuresare taken to prevent insect and fungus damage to the following crop, especially wherefollowing grassland.

Planting of trees and shrubs etc. may take place seven days after application. Grass seed maybe sown from five days after treatment; see ‘Recommendation Tables’ for specific instructionson direct drilled crops.

Weed resistance strategyThere is low risk for the development of weed resistance to PITCH.

Growers are encouraged to implement a weed resistance strategy based on (a) GoodAgricultural Practices and (b) Good Plant Protection Practices by:

• Following label recommendations

• The adoption of complimentary weed control practices

• Minimising the risk of spreading weed infestations

• The implementation of good spraying practice to maintain effective weed control

• Using the correct nozzles to maximise coverage

• Application only under appropriate weather conditions

• Monitoring performance and reporting any unexpected results to Nufarm UK Limited.

Strains of some annual weeds (e.g. Blackgrass, Wild oats and Italian ryegrass) have developedresistance to herbicides which may lead to poor control. A strategy for preventing andmanaging such resistance should be adopted. This should include integrating herbicides with a programme of cultural control measures. Guidelines have been produced by the WeedResistance Action Group and copies are available from the HGCA, CPA, your distributor, cropadviser or product manufacturer (Nufarm).

Sprayer hygieneIt is essential to thoroughly clean-out spray tanks, pumps and pipelines and nozzle or discassemblies, with a recommended detergent cleaner, between applying this product and otherpesticides to avoid contamination from pesticide residues. Traces of PITCH left in theequipment may seriously damage or destroy crops sprayed later.

Application and timing guidance

Cereals Apply, when the moisture content of the youngest crop grains is below 30%, not less thanseven days before harvest. Wheat crops, wheat volunteers and broadleaved weeds may requireup to 14 days before harvest

Use high clearance tractors with narrow wheels and crop dividers.

DO NOT TREAT CROPS GROWN FOR SEED.

Straw may be used for all purposes except as a horticultural mulch.

After harvest chop/incorporate, or remove straw as required.

Normal cultivations may be made after straw removal.

Effects on brewing and baking have not been tested. Consult grain merchant or processorbefore use.

NOTE: If dull weather persists after application, allow up to 14 days before harvest – particularly onbroadleaved weeds.

Annual nettle, Volunteer potato, Rosebay willowherb and Polygonum weeds will not be susceptibleat harvest management rates.

Oilseed rape and mustardsApply when crop seeds have less than 30% moisture content.

Apply to standing crops at these intervals before harvest: oilseed rape 14–21 days mustards 8–10 days

Use high clearance narrow wheeled tractors using wide booms and crop dividers.


For effective combining:

DO NOT treat crops with significant levels of secondary regrowth.

DO NOT treat late maturing areas of crops caused by pigeon damage, poor drainage, etc.

Crops suffering from stress, disease, extreme heat or drought may not mature evenly followingtreatment.

After harvest, chop/incorporate, or remove straw as required.

Normal cultivations may follow after straw removal.

Peas for combine harvesting and field beansApply when crop seeds have less than 30% moisture content.

Apply seven days or more before harvest.

This treatment cannot be used as a crop desiccant.

Use high clearance tractors with narrow wheels and crop dividers.

MIXING AND SPRAYING

Tractor mounted applicatorsConventional hydraulic sprayersSprayer and nozzle selectionAll machines should be capable of applying accurately 80–250 l/ha, as a MEDIUM or COARSEquality spray (BCPC definition) within a pressure range of 1.5–2.5 bars using 80 or 110 degreenozzles. For application pre-harvest of crops it is essential to use a sprayer whose boom may be raised to the correct height.

Water volumeFor general use 200–250 l/ha is the preferred volume range. For specific uses, volumes may be reduced to 80–120 l/ha by selecting low volume hydraulic nozzles, and adjusting pressure of application and tractor forward speed.

Spray pressurePressures must be related to tractor forward speed, desired water volume and nozzle type. A range of 1.5–2.5 bars must be used to ensure optimum results with minimum risk of drift.

Tractor forward speedSpeed of travel must be related to nozzle output characteristics. The typical range is from 4–9 kph. The slower speeds should be selected for applications pre-harvest of crops andwhere soil conditions could cause excessive boom bounce and yaw at faster speeds.

Recommended nozzle type, pressure, volumes and tractor speeds for the application of 80–120 l/ha80 or 110 degree nozzles able to apply the required volume at pressures between 1.5–2.5 barsat between 4–9 kph are recommended.

Filling the sprayerHalf fill the spray tank with water and start agitation. Add recommended quantity of PITCHherbicide, top-up tank with water to required level. To avoid foaming do not use top tankagitation. Use of a defoamer may be necessary.

CalibrationBefore using a sprayer and, especially, after nozzles have been changed, it is essential tocalibrate the sprayer by checking the output of at least one nozzle for each separate boomsection of the sprayer.

Operation in the fieldCheck the following before starting to spray:• The nozzles are aligned evenly at the correct angle to the direction of travel.• The boom is level over its width.• The boom height permits the correct pattern of spray overlap on the target weeds.

Product sold in bulk (1000 litre) containers must only be transferred from the top of thecontainer using the correct dry-break coupling system. The container must only be opened as

instructed. The concentrate must be sufficiently agitated and recirculated to ensurehomogeneity before use.

Rotary atomisersSprayer selectionThe following rotary atomiser applicators may be used to apply this product:

Cleanacres Dual-Option Sprayer CDA Boom and CDA Lightweight

Horstine Farmery Microdrop Lely Hydraspin

Tecnoma Girojet

Stir the correct amount of PITCH to control the target species into the sprayer bottle filled withclean water. Top up with water, close the top and shake gently to ensure good mixing. Do nottank-mix.

Droplet size and water volumeSet the spray droplet Volume Median Diameter to within the range 200–300µm for eachmachine – this corresponds to a MEDIUM or COARSE quality spray (BCPC definition) and thevolume of application to 40 l/ha.

Operation in the fieldApply at 4–9 kph having calibrated the sprayer accurately. Ensure that sprayer bouts arematched by using markers.

Hand-held applicatorsOverall, non-selective applications – spot or directed applicationKnapsack applicatorThese may be used in orchards and non-crop areas. Normal water volume is 200–300 l/ha butby fitting low volume nozzles it can be reduced to 100–150 l/ha. All applications to be as aMEDIUM or COARSE quality spray (BCPC definition).

Example of useWhen used at a walking speed of one metre/second to apply a swath of one metre width, mostknapsack sprayers fitted with a Lurmark AN 2.0 or similar nozzle deliver approximately 200 l/haspray volume (or 10 l per 500 m2). To apply 2.67 l/ha of PITCH, therefore, use 26 ml of productfor each two litres of spray liquid required. Similarly, knapsack sprayers fitted with low volumenozzles such as Lurmark AN 1.0 typically deliver approximately 100 l/ha spray volume. To apply2.67 l/ha PITCH in this case, use 52 ml of product for each two litres of spray liquid required.

Tractor-mounted wipersTreatment of sugar beet bolters, weed beet and other weedsFor use in arable crops and grassland areas. Ensure there is at least 5 cm between the top ofthe tallest desired vegetation and the impregnated wiper. Weeds should be a minimum of 10 cm taller than the desired vegetation for safe application. Two passes in opposite directionswill be needed where weeds are dense and successive applications will be required to controlweeds that were below the original wiping level. Treat before weed seeds have matured toreduce to a minimum seed return to the soil, Bolting beet should be treated by a series of threeapplications during early July to early August with two weeks between treatments.

WEEDS MUST BE GROWING ACTIVELY TO BE SUSCEPTIBLE.

DO NOT USE WIPER TECHNIQUES IN SOFT FRUIT CROPS.

For advice on appropriate weed wiper applicators, consult Nufarm.

For best results with all wiper applicators– Operate at speeds below 5 kph.

– Treat when weeds reach 10 cm above the desired vegetation.

– Keep wiping surfaces wet but prevent dripping.

– Clean ropes several times a day to maintain optimum flow rate.

CAUTIONKeep stock out of treated areas for seven days to allow the herbicide to become fully effective.

TREATED POISONOUS PLANT SPECIES MUST BE REMOVED BEFORE REGRAZING ORCONSERVING.

COMPATIBILITYPlease contact your Nufarm distributor for a full list of compatible mixtures.

Do not tank-mix this product with other pesticides or fertilisers, EXCEPT when directed byNufarm, as a reduced level of weed control may result.

COMPANY ADVISORY INFORMATIONThis section is not part of the Product Label under the Control of Pesticides Regulations 1986(or Plant Protection Products Regulations 1995) and provides additional advice on the product.

GeneralPITCH herbicide is an advanced formulation containing the isopropylamine and potassium saltsof glyphosate. PITCH is taken up by foliage and translocated to underground roots, rhizomesand stolons, providing control of both annual and perennial grasses and broadleaved weeds.PITCH is rapidly adsorbed onto particulate matter in soils and water and is quickly degraded bythe micro-organisms present in soil and aquatic bottom sediments. Until degraded, the activeingredient in PITCH, glyphosate, is practically immobile in soils and is, therefore, unlikely tocontaminate groundwater.

To maximise the safety of PITCH to the operator, consumer and environment, the labelrecommendations and the DEFRA/HSE/DETR publication ‘Code of Practice for the Safe Use ofPesticides on Farms and Holdings’ (Green Code) should be adhered to.


Symptoms on the weedsSymptoms of treatment are generally first seen 7–10 days, or longer (if growth is slow), afterspraying. These take the form of leaf reddening followed by yellowing and are usually quickerto appear on grasses than on broadleaved weeds. Reaction of nettles is slow.

Sprayer maintenanceEnsure that the sprayer is in good working order by paying particular attention to the conditionof the pump, hoses, nozzles or disc assemblies and pressure gauge. Replace damaged, worn ormalfunctioning parts. If extra filtration or pressure damp valves have been fitted for low volumework at 80–120 l/ha make certain this equipment is clean and functioning correctly. Carry outmaintenance according to the instructions of the sprayer manufacturer. This is of utmostimportance when using low volume nozzles.

Hygiene when using all sprayersIt is essential to thoroughly clean-out sprayer tanks, pumps and pipelines and nozzle or discassemblies, with a recommended detergent cleaner, between applying this product and otherpesticides to avoid contamination from pesticide residues. For example, after spraying thisproduct pre-harvest in cereals the equipment MUST be cleaned completely before it is used toapply a potato blight fungicide, particularly in seed crops.

DisposalFollow the guidance on the disposal of surplus spray solution, tank washings, concentrate andcontainers as given in the DEFRA/HSC/NAW publication ‘Code of Practice for Using PlantProtection Products’ of January 2006.
