Florasulam 6.25g/L + 2,4-D Ester LV 300g/L

Post-em cereal broadleaf herbicide

Will control all Conclude* labelled weeds plus more

Vortex® Overview

3Available in 20L only

Parameter Florasulam 2,4-D Ester LVConcentration (g/L) 6.25 300

HRAC Group B I

MOAInhibitor of acetolactate synthase (ALS

inhibition)Disruption of plant cell growth

Plant uptake Foliar, shoots, roots Foliar

Activity Systemic (xylem and phloem) Systemic

Translocation Extensive Extensive

Site of action Apical meristem Shoot and shoot meristems

Soil residualShort soil residual. Dependant on rate and

rainfall. Not strongly influenced by pH.No

Visual symptoms

Plants will appear stunted and chlorotic,

will often have necrotic (brown) leaf

margins, and will exhibit gradual death

Twisting/distortion of stems and leaves

followed by wilting, necrosis and death.

First symptoms 7-14 days 2-4 days

Spray to control

interval28 - 42 days 28 days

Vortex® Modes of Action

4

Strong fit across all key cereal growing regions

Strong mid – late season broadleaf option.

Very broad spectrum

Flexible application from mid tillering to booting

Controls hard to kill BLW weeds

Double Mode of Action aids in spectrum and resistance management

Vortex® Positioning

5

Flexible application window

Z32Z15 Z37

Vic, Tas, SA, WA = 5 leaf stage to booting (Z15 – Z37)

Qld, NSW = 5 leaf stage to 2nd node (Z15 – Z32)

Best results will be achieved where weeds are targeted early.

Application Window

6

Robust rates and multiple groups of herbicides are important to prevent the

onset of resistance and preserve useful chemistry.

With resistance not present…dual mode like Vortex is a good preventative

strategy

With low level resistance…dual mode gives good chance of control

With developed resistance…rotation and mixtures of Vortex with products

such as Velocity reduces reliance on still effective MOA such as HPPD

Great weed spectrum in all key growing regions. Vol legumes, Turnip, Radish,

Bindweed, Thistles, Spiny Emex (Doublegee), Vol Canola,

Ideal for where Conclude and other group B + phenoxy tank mixtures are used

Low residual group B giving plant back flexibility.

Flexible application, fits early but can go later and highly compatible

Excellent value when compared to other premium broadleaf options

Features & Benefits

Features Benefits

Unique combination of actives with dual

modes of action

Increased efficacy on difficult to control broadleaf

weeds with a wide spectrum of activity

Stops weeds growing almost

immediatelyImproved yields from reduced competition

Short grazing withholdingGreater flexibility to graze or cut crops in mixed

farming enterprises

Flexible application window Makes it easier to work around weather events

and apply early or late

Short residual group B component.Allows versatility in crop sequencing and

paddock rotation

Terbutrex®

550 mL/Ha

SC 500 g/L terbutryn Adama Not compatible. Significant phyto occurred in

field trials and there is a risk of significant crop

injury when Terbutrex® is used with oil.

What is the best timing to use Vortex?

Crops are most vulnerable to weeds at the critical establishment phase and

this is typically when the greatest yield losses occur from weed competition.

Vortex will give the best results when used early in the crop

establishment phase. Early applications within the recommended

application window can start at the 5 leaf stage (Z15).

In situations where an early timing has not been practical through

excessive wet weather or for other reasons Vortex is an excellent mid-late

season option giving superior control of larger weeds, especially when tank

mixed with another broadleaf herbicide. Late applications can be applied

right up to booting (Z37) or 2nd Node (Z32) if in Qld, WA or NSW.

Frequently Asked Questions

42

If I use Vortex on Climbing Buckwheat will it be good enough alone or will

I need to tank mix with another Climbing Buckwheat product?

Vortex is registered for the suppression of Climbing Buckwheat when used

alone at 820mL and in trials the solo rate has shown control levels as high as

80%, especially where weeds have been sprayed small.

When tank mixed with another Climbing Buckwheat product like Enforcer 242

or Hotshot the level of weed control seen in trials has been as high as 95%

Adama recommend a solo application may be the most economically viable

option where Climbing Buckwheat pressure is low and the weeds small and

actively growing, while the preferred treatment for higher pressure situations or

where weeds are larger or not as actively growing will be a tank mix.


43

Can I use Vortex on Oats?

No, Vortex is not registered for use in Oats. Whilst Vortex has shown adequate crop

safety against Oats in some trials in others it was shown to be too damaging and not

worth the risk. Hence Adama have taken the decision not to include Oats in the

registration.


44

Will Vortex work on resistant weeds like Wild Radish?

Whilst there is widespread resistance to group B herbicides, resistance to group I’s

are much less common and using dual mode of action products like Vortex which

include both groups will give a greater likelihood of control where resistance is

present. Also what is not well know is the level of cross resistance between the sub

groups of the group B chemistry class, it cant always be assumed that weeds

resistant to the SU’s (sulfonylureas) will be resistant to the sulphonamides like

florasulam.

If group B resistance is suspected and especially if group B and group I resistance is

suspected Adama recommend that alternative herbicide groups be used (such as in

Triathlon) or that Vortex be tank mixed with an alternative herbicide group such

Velocity.


Very broad spectrum weed control including Wild Radish, Climbing

Buckwheat, Thistles, Spiny Emex (Double Gee) and Vol Pulses,

Ideal for where Conclude had a proven fit

Low residual group B giving plant back flexibility.

Flexible application, fits early but can go later and is highly compatible

Excellent value when compared to other premium broadleaf options
