IUPAC

2-chloro-6′-ethyl-N-isopropoxymethylacet-o-toluidide

CAS

2-chloro-N-(2-ethyl-6-methylphenyl)-N-[(1-methylethoxy)methyl]acetamide

CAS No.

86763-47-5

Molecular Formula

Molecular Structure

General Product Information

Category

Herbicides > Anilide herbicides
Herbicides > Amide herbicides

Activity

Herbicide.
The product is absorbed by the shoots of germinating plants and inhibits protein synthesis in susceptible plants. Field trials conducted between 1995-98 at the Institute of Plant Protection in Poland on winter wheat, winter barley, sugarbeet, pea, potato and maize showed effective control of Apera spica-venti and Echinochloa crus-galli and improved crop yield.

CropUse

Crop uses:
Apples, beans, cotton, lupins, maize, onions, peanuts, peas, potatoes, rice, soybeans, sugar beet, sunflowers, vines

1,000-2,000 g ai/ha

Premix
