| Mode of Action |
Cell division inhibitor. It is reported that chloroacetamides inhibit synthesis of very long chain fatty acids (J. Schmalfuss et al., Abstr. Meeting WSSA, Toronto, 2000, 40, 117–118; P. Böger, Abstr. III Int. Weed Control Congr., Brazil, 2000). Maize tolerance of chloroacetamides is attributed to rapid detoxification by glutathione S-transferases. Selective herbicide, absorbed predominantly by the hypocotyls and shoots. Inhibits germination. |
| Uses |
Control of annual grasses (Echinochloa, Digitaria, Setaria, Brachiaria, Panicum and Cyperus spp.) and some broad-leaved ****s (Amaranthus, Capsella and Portulaca spp.) 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 0.6–1.6 kg/ha. Often used in combination with broad-leaved herbicides, to extend the spectrum of activity. |
