A field experiment was conducted during kharif 2017 at SHUATS, Allahabad (U.P.) to compare the efficacy of selected insecticides against maize stem borer [(Chilo partellus (Swinhoe)] of maize. The experiment was conducted in a Randomized Block Design with seven treatments; (T¹) Fipronil 5EC, (T²) Carbofuran 3G, (T³) Lamda cyhalothrin 5EC, (T⁴) Novaluron 10EC, (T⁵) Flubendiamide 480SC, (T⁶) Quinalphos 25EC, (T⁷) Chloropyriphos 20EC and (T⁸) Control each of which was three replications. Among all the treatments lowest per cent infestation of dead hearts was recorded in Carbofuran 3G (8.79%), then followed by Fipronil 5EC (9.04%), Novaluron 10EC (9.19%), Flubendiamide 480SC (12.87%), Lamda cyhalothrin 5EC (20.01%), Chloropyriphos 20EC (21.08%), Quinalphos 25EC (22.62%) and is least effective among all treatments. The cost benefit ratio (CBR) showed that the application of Chloropyriphos 20EC was economically most viable treatment (1:1.68) followed by Fipronil (1:1.61).
