Acetochlor Usage And Synthesis

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on the benzene ring while one of the methyl hydrogens as well as the hydrogen attached to the nitrogen atom have been replaced by a chloro and an ethoxymethyl group respectively.

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.

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.
