6 GENERAL DESCRIPTION:A post emergence, mainly foliar absorbed, selective herbicide for control of broad leaved weeds in cereals and grasses.
7 APPLICATION METHODS AND TIPS:Best results on young actively growing weeds in fine weather with rain a day or two after spraying.
Minimize drift as low concentrations can cause symptoms on sensitive crops.
Don't spray in inversion conditions.
Allow a 1 km buffer on the upwind side of sensitive species and use a coarse spray when the wind is between 3 and 20 kph. A 10 m buffer is sufficient on the down wind side of sensitive plants.
8 WEATHER:Rainfast in 1 hour.
Frost effects: Poorer weed control in frosty conditions
Wind: Ensure wind is away from sensitive crops.
Inversions: Don't apply in inversion conditions
Delta T and relative humidity: Avoid application when Delta T is greater than
9 ADJUVANTS:Wetting agents: Use a wetting agent when spraying hard to wet weeds.
Spray oils: Compatible with spray oils. These are usually only added when a companion product in a tank mix requires them.
10 WATER QUALITY:Hard water:
11 COMPATIBILITY:Trace elements.
See HerbiGuide Compatibilities button.
12 EQUIPMENT:Boom spray:
Flat fan nozzles at 150-400 kPa.
Carrier is usually water.
Water volume; at least 80 L/ha is recommended on the label with a medium (ASAE S572) spray quality. Rates down to 30 L/ha can be used providing the droplet density is maintained at more than 50 droplets per square centimetre.
Hand spray:Label recommends coarse to very coarse (ASAE S572) spray using number 6-8 tips at 700-1500 kPa and applying 3000 L/ha water.
Rates of 500-1000 L/ha using finer nozzles pressures of 400-600 kPa are adequate.
13 SPRAYER DECONTAMINATION:Clean Up:
Remove filters and nozzles and manually clean separately. Rinse with soapy water or water plus wetting agent and run through boom. Rinse with water.
Decontamination:Remove filters and nozzles and manually clean then soak in 500 mL household ammonia in 10 L water for 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. Fill with 1% solution of ammonia and leave for several hours. Triple rinse with water. Or use a commercial spray tank and equipment cleaner.
Rinse nozzles and filters in water and replace.
Don't use chlorine based cleaners.
14 HERBICIDE RESISTANCE:None reported.
Plant populations resistant to group I herbicides will probably be tolerant to Hotshot. Repeated application may lead to the development of resistant populations of weeds.
