Field efficacy of different insecticides against ear head caterpillar (Helicoverpa armigera Hub.) infesting finger millet

Abstract

A field experiment was conducted to determine the efficacy of Emamectin benzoate 5 SG, Chlorantraniliprole 18.5 SC, Spinosad 45 SC, Lambda cyhalothrin 5 EC, Beta cyfluthrin + Imidacloprid 19.81+8.49 W/W, Profenofos 50 EC, Chlorpyriphos 20 EC and NSE 5% against the surviving larval population of finger millet ear head caterpillar Helicoverpa armigera (Hub.) on finger millet in the experimental research area of farmers field in Beedshed village, Dist- Kolhapur during Kharif season of 2015. In newer insecticides lowest number of survival population of larvae was recorded in treatment Spinosad 45 SC @ 75 g a.i./ha 0.61 number of larvae per ear head followed by Chlorantraniliprole 18.5 SC @ 10 g a.i./ha 0.62, Emamectin benzoate 5 SG @ 9.5 g a.i./ha 0.64.
