6 GENERAL DESCRIPTION:A post emergence, selective, foliar absorbed, translocated agricultural herbicide. It is used for control of a range of weeds in established turf and cotton.
7 APPLICATION METHODS AND TIPS:Best results on young actively growing plants in moist soil.
Ensure thorough coverage.
For turf, avoid mowing for a few days before and after spraying.
Keep the spray mix agitated.
Avoid drift off the target area as sensitive plants are susceptible to very low rates. Downwind buffers of 30 m to native vegetation and 10 m to water bodies apply.
8 WEATHER:Rainfast in 3 hours. Do not apply if heavy rain is forecast as runoff into waterways may occur.
Wind: Apply when wind is between 3 and 10km/hr.
Inversions: Avoid application during low level inversions as excessive drift may occur.
Temperature: Do not apply to cotton under cool overcast conditions.
Delta T and relative humidity: Avoid application when Delta T is greater than
9 ADJUVANTS:Wetting agents: Use a non ionic surfactant at 0.25-0.5% of spray mix for most applications.
10 WATER QUALITY:Hard water:
pH: Use a buffering agent if the pH is less than 5.5.
Tank life: Tends to settle and can be difficult to redisperse. Avoid leaving in the tank overnight.
11 COMPATIBILITY:Trace elements.
See HerbiGuide Compatibilities button.
12 EQUIPMENT:Boom sprays:
Carrier volume: 100-800 L/ha recommended on label. Lower rates are OK if finer sprays are used to ensure adequate coverage.
Nozzles: Flat fan.
Pressure: 150-400 kPa.
Droplet size: Use medium to course droplets with VMD of 250-400 microns.
Aerial application:Carrier volume: Not recommended for aerial application.
Other:Not recommended for application through irrigation.
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 (eg 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.
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 (eg 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.
14 HERBICIDE RESISTANCE:Tolerant plants are expected to occur and may dominate the weed population after repeated applications.
