ABSTRACT
An experiment was conducted during kharif, 2015-16 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. From the bio efficacy trail samples were collected at 0, 1, 3, 5, 7, 10 and 15 days after third spray during kharif 2015-16. Samples were analyzed at All India Network Project on Pesticide Residues, Rajendranagar, Hyderabad. The dissipation pattern of lambda cyhalothrin 5% SC @ 15.63 g a.i ha-1 was studied collecting samples at regular intervals i.e. 0, 1, 3, 5, 7, 10 and 15days after last spray. The initial deposits of 1.20 mg kg-1 lambda cyhalothrin recorded at 2 hours after last spray and dissipated to 0.78, 0.36 and 0.09 mg kg-1 at 1, 3 and 5 days after last spray respectively and below determination level (BDL) by 7th day.
Key words: Insecticides, Thrips, Initial deposit, Efficacy, Dissipation, Below Determination Level.
