Dissipation kinetics of flubendiamide on chili and soil.

Average initial deposits of flubendiamide on chili were found to be 1.06 and 2.00 mg kg(-1), respectively, following two applications of flubendiamide 480SC at 60 and 120 g a.i. ha(-1) at 10 days interval. More than 80% of flubendiamide residues dissipated just after 3 days of the last application at both the dosages. Residues of flubendiamide dissipated below detectable level of 0.01 mg kg(-1) in 7 and 10 days at single and double dosages, respectively. Half-life (t(1/2)) of flubendiamide on chili was observed to be 0.96 and 0.91 days, respectively, at single and double dosages. Desiodo flubendiamide was not detected at 0.01 mg kg(-1) level in chili samples collected at different time intervals. Red chili and soil samples collected after 20 days did not reveal the presence of flubendiamide or its metabolite desiodo flubendiamide.
