Acetochlor Chemical Properties,Uses,Production
Description
Acetochlor is a member of the chloroacetanilide compounds. It is used as herbicide to control against grasses and broadleaf weeds in corn, soya beans, sorghum and peanuts grown in high organic content. It is applied to the soil as a pre- and post-emergence treatment. It is mainly absorbed by the roots and leaves, inhibiting protein synthesis in shoot meristems and root tips.

Uses
Herbicide.
Definition
ChEBI: A monocarboxylic acid amide that is N-phenylacetamide carrying an ethyl and a methyl group at positions 2 and 6 respectively on the benzene ring while one of the methyl hydrogens as well as the hydrogen attached to the nitrogen atom have been replaced by a chloro and an ethoxymethyl group respectively.
Production Methods
Acetochlor is commercially produced through a two-step chemical synthesis starting from 2-ethyl-6-methylaniline. In the first step, this compound reacts with chloroacetyl chloride to form an anilide intermediate. This intermediate is then treated with chloromethyl ethyl ether in the presence of sodium hydroxide, resulting in the formation of acetochlor.
Agricultural Uses
Herbicide: A U.S. EPA restricted Use Pesticide (RUP). Approval pending in the EU. A pre-emergence herbicide for control of annual grasses and broadleaf weeds. It is used on cabbage, citrus cops, coffee, all types of corn, cotton, green peas, maize, onion, peanuts, potatoes, vineyards, sugar cane, and sugar beets, among others. It is compatible with most other pesticides.

Mechanism of action
Selective, absorbed mainly by shoots and roots of germinating weeds. Inhibition of very long chain fatty acids (VLCFA, inhibition of cell division)
Metabolic pathway
The initial metabolism of acetochlor is investigated to delineate the detoxification pathway using tolerant corn and soybean seedlings. Acetochlor is rapidly absorbed and metabolized by etiolated corn seedlings to the glutathione conjugate and is also rapidly metabolized by etiolated soybean seedlings. However, the initial metabolite by soybean seedlings is the homoglutathione conjugate, not the glutathione conjugate.
