Description

Esfenvalerate is one of the four isomers of the pyrethroid insecticide fenvalerate[1].

In Vivo

Esfenvalerate (0.1, 1, 7.5 or 15 mg/kg/day; gavage; from gestation day (GD) 13 to 19) shows clinical signs of neurotoxicity with 15 mg/kg/day[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
