S-Metolachlor | |||
Molecular formula |
| ||
Chemical name | A mixture of (S)-2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl)acetamide and (R)-2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl)acetamide in the proportion 80-100% to 20-0% | ||
Classification | Herbicide / Agrochemical | ||
Biochemistry | Cell division inhibitor; more recent research suggests chloroacetamides may inhibit synthesis of very long chain fatty acids. Maize tolerance of chloroacetamides is attributed to rapid detoxification by glutathione S-transferases. | ||
Mode of action | Selective herbicide, absorbed predominantly by the hypocotyls and shoots; inhibits germination. | ||
Usage | 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. | ||
Phytotoxicity | Tolerated by most broad-leaved crops, maize, sorghum (when safened wth fluxofenim or oxabetrinil). | ||
Mammalian Toxicology | Oral: Acute oral LD50 for rats 2672 mg/kg. Skin and eye: Acute dermal LD50 for rabbits >2000 mg/kg; non-irritant to skin and eyes (rabbits); may cause sensitisation by skin contact (guinea pigs). Inhalation: LC50 (4 h) for rats >2910 mg/m3. | ||
