| Questions And Answer | Back Directory | [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.

| Hazard Information | Back Directory | [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been replaced by a chloro and an ethoxymethyl group respectively.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. | [Trade name]

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. | [storage]
