An experiment was conducted during kharif, 2015 to evaluate the efficacy of seven insecticides viz., fipronil 5% SC @ 500 g a.i ha -1 , spinosad 45% SC @ 125 g a.i ha -1 , chlorantraniliprole 20% SC @ 30 g a.i ha -1 , profenophos 50% EC @ 400 g a.i ha -1 , lambda cyhalothrin 5% SC @ 15.63 g a.i ha -1 , imidacloprid + beta cyfluthrin 300% OD @ 30 g a.i ha -1 and dimethoate 30 % EC @ 300 g a.i ha -1 against chilli thrips. The dissipation pattern of dimethoate 30 % EC @ 300 g a.i ha -1 was studied collecting samples at regular intervals i.e. 0, 1, 3, 5, 7, 10 and 15 days after last spray and analyzed. The initial deposits of 3.86 mg kg -1 dimethoate recorded at 2 hours after last spray dissipated to 2.66, 2.28, 1.06, 0.22 and 0.08 mg kg -1 at 1, 3, 5, 7 and 10 days, after last spray respectively and below determination level (BDL) by 15 th day.
