Pyraclofos Chemical Properties,Uses,Production
Uses
Pyraclofos is used to control Lepidoptera, Coleoptera, mites and nematodes in fruit, vegetables, ornamentals and forestry. It has also been used in a human health application to control filarial worms.
Metabolic pathway
Pyraclofos is apparently subjected in insects to a metabolic activation to yield a more active acetylcholinesterase inhibitor which is possibly a thiooxidized metabolite. The compound is very rapidly degraded in mammals to inactive metabolites via P-O-aryl, P-O-alkyl and P-S-alkyl cleavage which explains its favourable selective toxicity. In both mammals and plants the principal degradative route is via P-O-aryl cleavage to give 1-(4-chlorophenyl)-4-hydroxypyrazolwe hich is rapidly conjugated.
Metabolism
Pyraclofos is metabolized to an active AChE inhibitor, probably by the oxidation of the sulfur atom in the phosphorothiolate linkage. The half-life in soil is 3–38 d, depending on soil type.
