Application

Diuron is a systemic herbicide, absorbed principally by the roots, with translocation acropetally in the xylem.

Used to total control of weeds and mosses on non-crop areas at 10-30 kg a.i./ha. Selective control of germinating grass and broad-leaved weeds in many crops, including asparagus, tree fruit, bush fruit, citrus fruit, vines, olives, pineapples, bananas, sugar cane, cotton, peppermint, alfalfa, forage legumes, cereals, maize, sorghum, and perennial grass-seed crops at 0.6-4.8 kg/ha. Phytotoxic residues in soil disappear within 1 season at these lower rates.
