The bio efficacy of Flubendiamide 90 + Deltamethrin 60 – 150 SC against the pod borer in chick pea was evaluated using four dosages of Flubendiamide 90 +  Deltamethrin 60 – 150 SC at the rate of 167, 200 and 250 ml/ha, along with conventional insecticides such as Deltamethrin 100 EC at 150 ml, Flubendiamide 480 SC at 47 and 100 ml, Quinalphos 25 EC at 1000 ml and Novaluron 10 EC at 750 ml/ha. The treatment Flubendiamide 90 + Deltamethrin 60 – 150 SC @ 250 ml/ha was found significantly superior to all treatments and caused highest reduction in the larval population of pod borer followed by Flubendiamide 480 SC at 100 ml and Flubendiamide 90 + Deltamethrin 60 and 150 SC at 200 ml/ha. Both these treatments were at par to each other and were next in order of effectiveness. Flubendiamide 90 + Deltamethrin 60 - 150 SC @ 250 ml/ha exhibited the lowest pod damage with a mean of 5.30 and 4.72 per cent as against 36.10 and 38.64 per cent in control that was followed by Flubendiamide 480 SC @ 100 ml/ha and Flubendiamide 90 + Deltamethrin 60 – 150 SC @ 200 ml/ha which exhibited 6.94 and 7.50; 9.49 and 10.86 percent pod damage during rab 2011-12 and 2012-13, respectively. Flubendiamide 90 + Deltamethrin 60 – 150 SC @ 250 ml/ha recorded significantly highest seed yield of 18.06 and 17.90 q/ha followed by Flubendiamide 480 SC @ 100 ml/ha and Flubendiamide 90 + Deltamethrin 60 – 150 SC @ 200 ml/ha, which yield 16.85 and 17.20 q/ha; 15.50 and 15.96 q/ha as against 10.53 and 11.40 q/ha in untreated control during rab 2011-12 and 2012-13, respectively.
