6 GENERAL DESCRIPTION:

A post emergent, selective, translocated, foliar absorbed herbicide for the control of many grasses in many broad leaved crops and pastures.

7 APPLICATION METHODS AND TIPS:

8 WEATHER:

Rainfast in 1 hours.
Frost effects: Avoid application to frost stressed plants. Frost 1 day after application usually tolerated.
Wind:
Inversions: Avoid application during low level inversions as excessive drift may occur.
Temperature:
Delta T and relative humidity: Avoid application when Delta T is greater than

9 ADJUVANTS:

Wetting agents: Use a nonionic wetting agent if spray volume exceeds 150 L/ha.
Spray oils: Uptake at 500 mL per 100 L spray solution is recommended in most situations. Use other oils at 1 L/100 L spray solution e.g. Ampol DC-Trate, BP Ulvapron Caltex Spray Plus, Tregspray, DC-Tron, Hasten and Synertrol are compatible.
Use wetting agent rather than oil if spraying peas or canola and downy mildew is present.
Use a wetting agent rather than oil if mixing with borad-leaved herbicides other than Lontrel (clopyralid).

10 WATER QUALITY:

Hard water: Tolerates the normal range of hard water.
Salty water: Tolerates reasonably salty water. (Stock drinking quality or better)
Colloids: Relatively tolerant of caly and colloids in water. If a coin can't be seen at the bottom of a 10 litre bucket then the water whould be cleared before use.
pH:
Tank life: 1 week.

11 COMPATIBILITY:

Trace elements.
Compatible with magnesium sulphate, zinc sulphate
Not compatible with products that aer highly alkaline or acidic or have high ion contents.
See HerbiGuide Compatibilities button.

12 EQUIPMENT:

Boom sprays:

Carrier volume: 50-150 L/ha recommended on label. 30-1000 L/ha is OK. Use higher volumes on dense stands. Use finer droplets if using low water volumes or spraying small weeds.
Nozzles: 110⁰ Flat fan preferred.
Pressure: 150-400 kPa.
Droplet size: 200-300 micron VMD. 110⁰ fan. Best results with fine droplets.

Aerial application:

Carrier volume: 30 L/ha minimum.

13 SPRAYER DECONTAMINATION:

Clean Up:
Clean soon after spraying to reduce the risk of forming dried deposits that may be difficult to remove.
Remove filters and clean separately. Triple rinse with water or water plus 0.25% wetting agent and run through boom.
Decontamination:
Remove filters and clean separately.
Rinse with water and drain.
Quarter fill the tank with an alkali detergent (eg 500 mL or g of Drive, Dynamo, Omo, or Surf per 100 L water) and circulate for at least 15 minutes then run through boom. Rinse twice with water.
Chlorine based cleaners are NOT recommended.

14 HERBICIDE RESISTANCE:

Tolerant plants are expected to occur and may dominate the weed population after repeated applications.
There are many populations of Annual Ryegrass that are resistant to haloxyfop and other group A hebicides. Do a resistance test.

17 RE-ENTRY PERIOD:

Wear protective clothing if in contact with the crop before the spray has dried.

18 PROTECTIVE CLOTHING:

Overalls, boots and washable hat. Use gloves and face shield when handling the concentrate.

19 SOIL:

Soil texture: Generally haloxyfop is more efficacious in lighter soils.
Soil pH: Little effect.
Soil organic matter: Little effect.
Soil moisture at application: Best results when soil is moist. Extremes of soil moisture (too wet or too dry) that affect plant growth should be avoided.

20 MODE OF ACTION:

Post-emergent. Group A, acetyl CoA carboxylase inhibitor.

Uptake and translocation:

Absorbed by foliage and to a lesser extent by roots. Translocated to to actively growing meristematic tissues where growth is inhibited.

Physiological effects:

The product is hydrolysed to haloxyfop which is then translocated
Tolerant plants break haloxyfop down.

Residual Life and Breakdown:

Slight residual activity occasionally provides some useful control of later germinating grasses.

21 SELECTIVITY:

Crop tolerance:

In general, do not apply after the crops have commenced flowering.
Don't tankmix with Blazer or Basagran for applications on Cowpeas.

Varietal sensitivities:

Effect on Clover Species:

Little effect.

Effect on Medic Species:

Little effect.

Effect on Lucerne:

Little effect.

Effect on Native Plants:

Little effect on broad leaved native species. May affect some native grasses and Geranaiceae.

22 DISEASE AND INSECT EFFECTS:

Oil should NOT be added to haloxyfop when it is applied to canola or field peas as it susceptibility to Downy Mildew.

23 PLANT SYMPTOMS:

Yellow or black spotting of leaves follwed by yellowing or reddening then death from the tips.

SECONDARY EFFECTS:
