Efficacy of novel insecticides against POD borer,Helicoverpa Armigera(HUBNER) in Chickpea

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 cypermethrin 25 EC @ 1250 ml/ha biopesticide viz., B t @ 1.5 kg/ha and botanical viz., Neemarin 1500 ppm @ 3000 ml/ha, which were sprayed on chickpea variety surya against pod borer, Helicoverpa armigera (Hubner) during rabi 2011–12 and 2012–13. 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 infestation than untreated control. Flubendiamide was best with lowest pod infestation of 10.73 and 12.59%, respectively and 16.84 q/ha yield followed by indoxacarb, spinosad, novaluron, carbosulfan, bifenthrin, lambda cyhalothrin, cypermethrin, neemarin and Bt.
