5 - Aryloxy Acids

Abstract

2 ,4-D and 2, 4-DP are the first compounds that are discussed among aryloxy acids. These are used as herbicides. Diclofop methyl is a selective herbicide used in the control of Alopecurus myosuroides (black-grass, slender foxtail), a major annual grass weed in winter cereal crops in Western Europe. Diclofop methyl is hydrolyzed to the corresponding propionic acid that undergoes further degradation to give polar metabolites. The amounts of the metabolites depend on the metabolism activity of the individual biotypes. Fenaxoprop ethyl is a herbicide used to control a selective herbicide: control of Alopecurus myosuroides (black-grass, slender foxtail), a major annual grass weed in winter cereal crops in Western Europe. Fluazipop butyl is a herbicide that is a potent inhibitor of plasticidic enzyme acetyl-coenzyme A carboxylase. Haloxyfop methyl is an experimental post-emergent herbicide and controls annual and perennial grasses in a variety of broad-leaved crops. Trichlopyr is a post-emergent herbicide controlling a wide range of broad-leaved and woody weeds, use for forestry and right-of-way clearance.
