Abstract
The present investigation entitled “Field efficacy of certain insecticides against Maize stem borer [Chilo partellus (Swinhoe)]” was conducted at the Central Research Field, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, U.P. during Kharif 2018. Among all the treatments studied, lowest per cent infestation of stem borer was recorded in Carbofuran (7.98), followed by Spinosad (9.71), Chlorpyriphos + Cypermethrin (11.10), Chlorpyriphos (11.45), Fipronil (12.14), Imidacloprid (12.84) and Dimethoate (14.92). The treatment Dimethoate (14.92) was least effective among all the treatments. The best and most economical treatment was T4 Carbofuran 3%G (1:1.96) followed by T3 Spinosad (1:1.80), T1 Chlorpyriphos 50%EC+ Cypermethrin 5%EC (1:1.68), T2 Fipronil 0.3% Gr (1:1.59), T5 Imidacloprid 17.8 %SL (1:1.59), T6 chlorpyriphos 20% EC (1:1.52), T7 Dimethoate 30% EC (1:1.32) as compared to T8 Control (1:1.21). All the treatments were found significantly superior to untreated control in reducing the maize stem borer infestation.
