Fenoxaprop-p-ethyl CAS:71283-80-2 CAS NO.71283-80-2

Active ingredient

Fenoxaprop-p-ethyl

Chemical name

(R)-2-[4-[(6-chloro-2-benzoxazolyl)oxy]phenoxy]propanoate

Classification

Herbicide / Agrochemical

Formulation

6.9%EW, 12%EC

Biochemistry

Fatty acid synthesis inhibition in grasses, by inhibition of acetyl CoA carboxylase (ACCase).

Mode of action

Fenoxaprop-P-ethyl is a selective herbicide with contact and systemic action, absorbed principally by the leaves, with
translocation both acropetally and basipetally to the roots or rhizomes.

Usage

Post-emergence control of annual and perennial grass weeds in potatoes, beans, soya beans, beets, vegetables, peanuts, flax,
oilseed rape, and cotton; and (when applied with the herbicide safener mefenpyr-diethyl) annual and perennial grass weeds and wild
oats in wheat, rye, triticale and, depending on ratio, in some varieties of barley. Phytotoxicity Non-phytotoxic to broad-leaved
crops. Formulation types EC
