WebThe major route of cypermethrin biodegradation begins with ester hydrolysis (Roberts TR and Standen ME, Pest Management Science, 8:305-319, 1977), a common initial step in pyrethroid metabolism, to produce the carboxylate, 3- (2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylate. WebMajor metabolic reactions ( Fig. 58.5) are ester hydrolysis and hydroxylation at the alcohol moiety. The metabolic fates of the alcohol moiety, α-cyano-3-phenoxybenzyl alcohol, was the same as those of pyrethroid insecticides having the same alcohol moiety such as fenvalerate, cypermethrin, and deltamethrin. how is the british economy doing after brexit
