抄録

Metabolic fate of fenvalerate [α-cyano-3-phenoxybenzyl-2-(4-chlorophenyl) isovalerate] and the [S]-acid ester isomer in bean plants was studied under laboratory conditions. When fenvalerate and the [S]-acid isomer were each applied to the leaf surface of bean plants at a rate of 10μg per leaf, both compounds similarly disappeared from the treated leaves with half-lives of approximately 14 days. On and/or in the plants, fenvalerate and the [S]-acid isomer underwent decarboxylation, ester cleavage, hydrolysis of the CN group to CONH2 and COOH groups, hydroxylation at 2′- and 4′-phenoxy positions, conversion of the alcohol moiety to 3-phenoxybenzyl alcohol and 3-phenoxybenzoic acid, and conjugation of the resulting carboxylic acids and alcohols with sugars. Very little of 14C was transferred to other parts of the bean plants. When bean plant seedlings were planted for 30 days in Kodaira light clay and Katano sandy loam soils treated with 1.0ppm of 14C-fenvalerate, roots retained fairly large amounts of 14C, shoots, pods and seeds contained very little 14C. No parent compound was detected in shoots.
