M.p.: 89-91 ºC. V.p.: 5.3x10-4 mPa (20 ºC). KOW: logP = 4.58. Henry: 2.74x10-4 Pa m3 mol-1 (calc.) S.g./density: 1.3 (20 °C). Solubility: In water 0.7 mg/l (pH 5.8, 20 ºC). In acetone 200, toluene 200, ethyl acetate >200, ethanol c. 24 (all in g/l, 20 ºC). Stability: Fenoxaprop-P-ethyl is stable for 90 d at 50 ºC. Not sensitive to light.

M.p.: 155-161 °C; V.p.: 1.8x10-1 mPa (20 °C). KOW: logP = 1.83-0.24 (pH 5 - pH 9). S.g./density: c. 1.5 (20 °C) Solubility: In water 0.27 (pH 5.1), 61 (pH 7.0) (both in g/l, 20 °C). In acetone 80, toluene 0.5, ethyl acetate 36, methanol 34 (all in g/l, 20 °C). 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.
