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

Temperature:

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:

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 allow to stand 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.
