Esfenvalerate

 ˳ʽ

Introduction: Esfenvalerate has replaced the compound fenvalerate for use in the United States. Much of the data for esfenvalerate is closely applicable to the pesticide fenvalerate because the two compounds contain the same components. The only difference in the two products is the relative proportions of the four separate constituents (isomers). Esfenvalerate has become the principal compound of the two because it results in lower application rates than fenvalerate, is less chronically toxic, and is a more powerful insecticide. The compound contains a much higher percentage of the one insecticidally active isomer (84% for esfenvalerate and 22% for fenvalerate). Esfenvalerate is a synthetic pyrethroid insecticide which is used on a wide range of pests such as moths, flies, beetles, and other insects. It is used on vegetable crops, tree fruits, and nut crops. It may be mixed with a wide variety of other types of pesticides such as carbamate compounds or organophosphates.

ENVIRONMENTAL FATE

Animals Rapid metabolism and elimination occurs in rats and other animals. Primary metabolism involves hydroxylation of 2'- and 4'- hydroxyl moieties, ester cleavage, hydroxylation and oxidation of the alcohol derivatives, oxidation of the cyano moiety and conjugation of the acidic metabolites with sulfate, glycine and glucuronic acid. Plants The major metabolite was decarboxylated fenvalerate. Ester cleavage, hydration of the cyano group to carboxamide and carboxylic acid, hydroxylation of the 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, also occur. Soil/Environment In sand (0.38% o.m.), Kd (25 ºC) 4.4; in sandy loam (pH 7.3, 1.1% o.m.), Kd (25 ºC) 6.4, DT50 88 d; in silty loam (pH 5.3, 2.0% o.m.), Kd (25 ºC) 71, DT50 114 d; in clay loam (pH 5.7, 0.2% o.m.), DT50 287 d; in clay loam (pH 6.4, 1.5% o.m.), Kd (25 ºC) 105.
