COMMERCIALISATION |
History The herbicidal enantiomer of fenoxaprop was reported by H. P. Huff et al. (Proc. Br. Crop Prot. Conf. - Weeds, 1989, 2, 717). Introduced by Hoechst AG (now Bayer AG) in 1988. |

APPLICATIONS |
fenoxaprop-P-ethyl |
Biochemistry Fatty acid synthesis inhibition in grasses, by inhibition of acetyl CoA carboxylase (ACCase). Rapidly hydrolysed in plants to the acid, which is still herbicidally active. 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. Applied at 40–90 g/ha in cereals (max. 83 g/ha in EU) and at 30–140 g/ha in broad-leaved crops. Phytotoxicity Non-phytotoxic to broad-leaved crops. |
