A post emergent, selective, foliar absorbed, translocated, short residual herbicide for the control of a wide range of broad leaved weeds in grass crops.
7 APPLICATION METHODS AND TIPS:
Best results on young actively growing plants.
Use a spray oil at 0.5-1%.
8 WEATHER:
Rainfast in 3 hours.
Frost effects: Poorer results in frosty weather and on frost affected plants.
Wind: Apply when wind speed is between 2 and 20 kph. Allow at least 100 m buffer on the upwind side of sensitive crops and use coarse droplets when spraying at higher wind speeds.
Inversions: Don't apply in inversion conditions. Drift may affect susceptible plants.
Temperature:
Delta T and relative humidity: Avoid application when Delta T is greater than
Soil moisture at application:
9 ADJUVANTS:
Wetting agents: Use wetting agent when tank mixing with products like metsulfuron.
Spray oils: Use a spray oil at 0.5-1%. Uptake is recommended on the label.

11 COMPATIBILITY:
Trace elements.
See HerbiGuide Compatibilities button.
12 EQUIPMENT:
Boom sprays:
Carrier volume: 50-100 L/ha recommended on the label. Use finer nozzles and ensure good coverage if lower rates are used.
Nozzles: Flat fan. Medium droplet size recommended on the label to reduce drift.
Pressure: 150-400 kPa.
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. 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. Rinse with water.
Decontamination:
Remove filters and 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:
Tolerant plants are expected to occur and may dominate the weed population after repeated applications.
Torpedo may not control group B and/or group I resistant weeds.

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:
No particular effect of soil type.
20 MODE OF ACTION:
Clopyralid disrupts plant cell growth. Florasulam is an ALS inhibitor
Uptake and translocation:
Mainly absorbed through the foliage. Some root absorption. Translocated throughout the plant.
Physiological effects:
Clopyralid causes distortion of new growth.
