Fenvalerate

Use

Soil. Fenvalerate is moderately persistent in soil. The percentage of the initial dosage (1 ppm) remaining after 8 weeks of incubation in an organic and mineral soil were 58 and 12%, respectively, while in sterilized controls 100 and 91% remained, respectively (Chapman et al., 1981).In a sugarcane runoff plot, fenvalerate was applied at a rate of 0.22 kg/ha 4 times each year in 1980 and 1981. Runoff losses in 1980 and 1981 were 0.08 and 0.56 of the applied amount, respectively (Smith et al., 1983).Plant. Dislodgable residues of fenvalerate on cotton leaf 0, 24, 48, 72 and 96 hours after application (0.22 kg/ha) were 0.85, 0.36, 0.38, 0.28 and 0.28 μg/m2, respectively (Buck et al., 1980).Surface Water. In an estuary, the half-life of fenvalerate was 27–42 days (Schimmel et al., 1983).Chemical/Physical. Undergoes hydrolysis at the ester bond (Hartley and Kidd, 1987). Decomposes gradually at 150–300°C (Windholz et al., 1983) probably releasing toxic fumes of nitrogen and chlorine.
