An experiment was conducted in the field to evaluate comparative efficacy of four insecticides viz. Dursban (Chloropyriphos 20 EC), Rogar (Dimethoate 30 EC), Curacron (Profenophos), and Tracer (Spinosad) along with untreated check against Pod borer (Helicoverpa armigera) on Lentil (Masoor) crop. The crop was sprayed with insecticides at Pod formation stage. Highly significant differences were observed among insecticides which has a varying degree of control in respect of decreased larval pest population and pod damage, whereas seed yield increased. Tracer was the most effective insecticide in reducing the population of Pod borer and decreasing maximum pod damage, followed by Dursban and Rogar. Curacron was found to be the least effective insecticide under this study. The maximum increase in seed yield per hectare was obtained with Tracer, whereas Rogar resulted minimum increase in seed yield over control.
