ENVIRONMENTAL FATE
Fluazifop-p-butyl breaks down rapidly in moist soils. Its half- life in moist conditions is generally less than a week. The major degradation product of fluazifop-p-butyl will also break down fairly rapidly. Its half-life is around three weeks.
Fluazifop-p-butyl is actively taken up by plants and translocated throughout the plant. The compound accumulates in the actively growing regions of the plant (shoots, root rhizomes, stolons of grass) where it interferes with the plant cell's ability to produce energy. In plants, fluazifop-p-butyl is rapidly broken down in the presence of water to fluazifop-p.
Usage: 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 CropScience). Manufacturers: Bayer CropScience; Sharda; Sundat; Tide. Fatty acid synthesis inhibition in grasses, by inhibition of acetyl CoA carboxylase (ACCase).
Application: 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.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.
