Uses:
Selective, systemic, growth-regulator herbicide absorbed by leaves and translocated readily throughout the plant in the phloem. Post-emergence control of many annual broad-leaved weeds, particularly black bindweed, common chickweed, cleavers and charlock in oilseed rape. In combination with other herbicides, used for control of a wider range of broad-leaved weeds in oilseed rape, cereals, grassland, clover, alfalfa and flax.
Toxicity
Rats' acute oral LD50 > 30 mg/kg, rabbit acute percutaneous LD50 > 2000 mg/kg. For skin and eyes have mild stimulation. The fish is no residual toxicity, toxicity.
Application
Used for winter road, rapeseed field weeds effectively control galium tricorne, numerous wisps, and cattle breeding wisp, tongue, big nest food, shepherd's purse, and grey dish of annual broad-leaved weeds.
