CropUse

Over 150 crops for control of annual and perennial weeds, woody brush, and trees. Use postdirected in tree and plantation crops, postemergence over soybeans, and postharvest in fallow periods and noncropland. Control of annual and perennial grasses and broad-leaved weeds, pre-harvest, post-planting/pre-emergence and in stubble, in cereals, peas, beans, oilseed rape, flax and mustard, at c. 1.5-2 kg/ha; as a directed spray in vines and olives, at c.4.3 kg/ha; in orchards, pasture, forestry and industrial weed control, at c. 4.3 kg/ha. As an aquatic herbicide, at c. 2 kg/ha.
