Efficacy of novel insecticides against pod borer, Etiella zinckenella (Treitschke) in vegetable pea.

A field experiment was conducted to determine the comparative efficacy of insecticides i. e. lambda cyhalothrin 5 EC @ 500 ml/ha, carbosulfan 25 EC @ 1000 ml/ ha, indoxacarb 14.5 SC @ 500 ml/ha, bifenthrin 20 EC @ 500 ml/ha, novaluron 10 EC @ 750 ml/ha, flubendiamide 39.35 EC @ 75 ml/ha, spinosad 45 SC @ 500 ml/ha and endosulfan 35 EC @ 1250 ml/ha biopesticide viz., Bt @ 1.5 kg/ha and botanical viz., Neemarin 1500 ppm @ 2500 ml/ha, were sprayed on vegetable pea variety arkel against pod borer, Etiella zinckenella (Treitschke) during rabi 2009-10 and 2010-11. The effect of these applications was also recorded on the yield attributes. All the treatments had the comparable lower number of larvae as well as pod and seed infestation than untreated control. Flubendiamide was best with lowest pod and seed infestation of 11.37 and 12.98%, respectively and 95.84 q/ha yield followed by indoxacarb, spinosad, novaluron, carbosulfan, bifenthrin, lambda cyhalothrin, endosulfan, neemarin and Bt, which gave 93.56, 91.63, 89.74, 83.22, 81.52, 79.42, 75.97, 72.78 and 68.99 q/ha yield, respectively.
