Application
|
Biochemistry Inhibits cell division by blocking protein synthesis; more recent research suggests chloroacetamides may inhibit
synthesis of very long chain fatty acids (J. Schmalfuss et al., Abstr. Meeting WSSA, Toronto, 40, 117-118, 2000; P. B鰃er, Abstr. III Int. Weed Control Congr., Brazil 2000). Mode of action Selective systemic herbicide, absorbed primarily by the germinating shoots, and secondarily by the roots, with translocation throughout the plant, giving higher concentrations in vegetative parts than in reproductive parts. Uses Used pre-emergence for the control of annual grasses and certain broad-leaved weeds in rice, both seeded and transplanted. It shows selectivity in barley, cotton, peanuts, sugar beet, wheat and several brassica crops. Effective rates range from 1.0-4.5 kg/ha. Activity is dependent on water availability such as rainfall following treatment, overhead irrigation or applications to standing water as in rice culture. Phytotoxicity Non-phytotoxic to rice, cotton, barley, wheat, peanuts, sugar beet, and some brassicas. Formulation types EC; GR.
