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.  

Usage: Fenoxaprop-P-Ethyl was introduced by Hoechst AG (now Bayer CropScience). It is a post-emergence herbicide used to control annual and perennial grasses.

Application: 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.
