6 GENERAL DESCRIPTION:

A post emergence, leaf absorbed, non-residual, contact herbicide applied as spray in water and usually mixed with a companion product.

7 APPLICATION METHODS AND TIPS:

Ensure thorough coverage.
DO NOT apply if runoff is expected within 3 days.
DO NOT sow or cultivate for 1 hour after spraying.
Don't use disk sowing systems or ones that allow treated soil to contact seed of broad leaved crops.

8 WEATHER:

Rainfast in 1 hour .
Frost effects:
Wind: less than 3 or more than 20 kilometres per hour recommended on label to reduce the risk of drift.
Inversions: Do not apply during temperature inversions.
Temperature:
Delta T and relative humidity:

9 ADJUVANTS:

Wetting agents: Usually improve performance.
Spray oils: Usually improve performance.

10 WATER QUALITY:

Hard water:
Salty water:
Colloids:
pH:
Tank life: Half life of 3-6 days.

11 COMPATIBILITY:

Trace elements.
See HerbiGuide Compatibilities button.

12 EQUIPMENT:

Boom sprays:

Carrier volume: 75-150 L water /ha
Nozzles: Flat fan.
Pressure: 150-400 kPa.
Droplet size: Coarse recommended on label to reduce risk of drift.

Aerial application:

Not registered for aerial application.
Carrier volume: 30 L/ha

13 SPRAYER DECONTAMINATION:

Clean up:
Clean soon after spraying to reduce the risk of forming dried deposits that may be difficult to remove.
Remove nozzles and filters and clean separately. Triple rinse with soapy water (e.g. 500 mL or g of Drive, Dynamo, Omo or Surf per 100 L water) or water plus 0.25% wetting agent and run through boom. This procedure is sufficient for spraying in other cereals or non selective applications.
Decontamination:
Remove the nozzles and filters and clean separately and allow to soak in a mixture of 500 mL chlorine bleach (4%) per 10 L water for at least 30 minutes.
Rinse sprayer with soapy water (e.g. 500 mL or g of Drive, Dynamo, Omo or Surf per 100 L water) or water plus 0.25% wetting agent and run through boom. Drain tank and flush with clean water for a minimum of 10 minutes to remove all traces of liquid fertilisers or adjuvants containing ammonia, such as ammonium sulphate or ammonium nitrate, before adding chlorine bleach, because bleach and ammonia will react to release a toxic gas.
Fill tank with clean water and add 300 mL household chlorine (4%) bleach per 100 L water, flush through hoses and boom then stand for 15 minutes with agitation engaged, repeat. Rinse tank, hoses and boom thoroughly with clean water to remove traces of bleach.
Rinse filters and nozzles in water and replace then rinse the whole system with water again.
