    APPLICATIONGS
    Cell division inhibitor; 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. Böger, Abstr. III Int. Weed Control Congr., Brazil 2000). Maize tolerance of chloroacetamides is attributed to rapid detoxification by glutathione S-transferases. Biochemistry
    Selective herbicide, absorbed predominantly by the hypocotyls and shoots; inhibits germination Mode of action
    Control of annual grasses (Echinochloa, Digitaria, Setaria, Brachiaria, Panicum, and Cyperus) and some broad-leaved weeds (Amaranthus, Capsella, Portulaca) in maize, sorghum, cotton, sugar beet, fodder beet, sugar cane, potatoes, soya beans, peanuts, sunflowers, various vegetables, and pulse crops. Applied pre-plant incorporated, pre-emergence or early post-emergence, at 0.8-1.6 kg/ha. Often used in combination with broad-leaved herbicides, to extend spectrum of activity. Uses
