Abstract:

An experiment was conducted during kharif, 2015 to evaluate the efficacy of eight insecticides viz., fipronil 5% SC, flubendamide 480% SC, chlorantraniliprole 20% SC, bifenthrin 10% EC, profenophos 50% EC, lambda cyhalothrin 5% SC, imidacloprid 17.8 % SL and beta cyfluthrin + imidacloprid 300 OD were studied byspraying thrice replicated thrice in randomized block design on field bean @ 500 g a.i ha-1, 60 g a.i ha-1, 30 g a.i ha-1, 812 g a.i ha-1, 400 g a.i ha-1, 15.63g a.i ha-1, 25 g a.i ha-1and 30 g a.i ha-1, respectively. Against major insect pests of field bean. The dissipation pattern of profenophos 50 EC (400 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 and analyzed. The initial deposits of 3.23 mg kg-1profenophos recorded at 2 hours after last spray dissipated to 1.68, 0.94, 0.58 and 0.19 mg kg-1 at 1, 3, 5 and 7 days, after last spray respectively and below determination level (BDL) by 10th day.


Keywords: Insecticides, thrips, initial deposit, efficacy and dissipation.
