An experiment on chickpea was conducted to determine the “Field efficacy of certain insecticides against pod borer, Helicoverpa armigera (Hubner) feeding on chick pea in Prayagraj” during rabi season of 2019-2020 at the Central Research Field, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. Efficacy of seven insecticides viz., Flubendiamide 20% WG @ 0.3g/lit, Spinosad 45% SC @ 0.5ml/lit, Indoxacarb 14.5% SC @ 1 ml/lit, Nisco sixer plus @ 2 ml/lit, Novaluron 10% EC @ 1.5 ml/lit, Nisco sixer plus + Novaluron 10% EC @ 1+ 0.75 ml/lit and Chlorantraniliprole 18.5 % SC @ 0.5 ml/lit were evaluated against the pest. Observations on gram pod borer population were recorded from fifteen randomly selected plants in each plot before spray and after 3, 7 and 14 days of spraying. The results revealed that all treatments are significantly superior over control. Among all the treatments Spinosad 45% SC was found best with maximum percent reduction of (78.23 %) followed by Chlorantraniliprole 18.5% SC (73.08 %). Flubendiamide 20% WG (64.96 %), Nisco sixer plus (59.18 %), Novaluron 10% EC (58.01 %), Nisco sixer plus+ Novaluron 10% EC (54.21 %), Indoxacarb 14.5% SC (51.33 %) was found to be least effective among all insecticides.
