Applications

fenoxaprop-P-ethyl

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.

Uses: 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; EW; SE.

Mammalian toxicology

fenoxaprop-P-ethyl

Oral: Acute oral LD50 for rats 3150-4000, mice >5000 mg/kg.

Skin and eye: Acute percutaneous LD50 for rats >2000 mg/kg.

Inhalation: LC50 (4 h) for rats >1.224 mg/l air.

NOEL: (90 d) for rats 0.75 mg/kg b.w. daily (10 ppm), mice 1.4 mg/kg b.w. daily (10 ppm), dogs 15.9 mg/kg b.w. daily (400 ppm).

Ecotoxicology

fenoxaprop-P-ethyl

Birds: Acute oral LD50 for bobwhite quail >2000 mg/kg.

Fish: LC50 (96 h) for bluegill sunfish 0.58, rainbow trout 0.46 mg/l.

Daphnia: LC50 (48 h) 0.56 (pH 8.0-8.4), 2.7 (pH 7.7-7.8) (both mg/l).

Algae: LC50 (72 h) for Scenedesmus subspicatus 0.51 mg/l.

Bees: LC50 (contact) >300 ug/bee; (feed) >1000 ug/bee.

Worms: LC50 (14 d) for Eisenia foetida >1000 mg/kg soil.

Environmental fate

Plants: In plants, fenoxaprop-ethyl is metabolised via fenoxaprop to 6-chloro-2, 3-dihydrobenzoxazol-2-one.

Soil/Environment: In soil, fenoxaprop-ethyl is rapidly hydrolysed to fenoxaprop; DT50 1-10 d.
