Toxicity | LD50 orally in rats: 1160 mg/kg (Upchurch) |
2.6 monoethyl monochloroacetoaniline was obtained from the reaction of 2,6 monoethyl aniline with chloroacetic acid and phosphorus trichloride. Ethanol reacts with Polyoxymethylene in the presence of hydrochloric acid to produce chloromethyl ethyl ether. Acetochlor is then formed from the condensation of 2,6 monoethyl monochloroacetoaniline with chloromethyl ethyl ether.
amide selective pre-emergence herbicide, can be used for corn, cotton, soybean, peanut, rape, potato, sugarcane, sesame, sunflower, orchard and legume, Cruciferae, Solanaceae, asteraceae and Umbelliferae and other vegetable fields, control of annual grass weeds, a fertilizer can control the entire growth period of crops, no weed harm. Ineffective against perennial weeds.
rat oral LD50 1160mg/kg; Rainbow trout LC50 0.5mg/L(96H).
