Bio-efficacy of new chemicals against shoot and fruit borer of brinjal

Abstract

Field experiment was conducted to evaluate the bio-efficacy of various new chemicals against shoot and fruit borer of brinjal during kharif season of 2010-11. The experiment was conducted in Randomised Block Design with eight insecticidal treatments replicated thrice. The variety, Muktakeshi was used for experimental trial. The experiment was conducted at Sabour Agricultural College farm with plot size 5.25 x 4.50 m2. The different insecticidal treatments were Spinosad [email protected] ml/lit., Indoxacarb 14.5 [email protected]/lit, Emamectin benzoate 25 WG @ 0.4 gm/lit, Rynaxypr 18.5 [email protected] ml/lit. Flubendamide 39.35 [email protected] ml/lit, Deltamethrin 5 [email protected]/lit+Triazophos 35 [email protected]/lit, Endosulphan 35 EC@1ml/lit and untreated control. Among the different insecticidal treatments, by application of Emamectin benzoate 25 [email protected]/lit recorded lowest fruit damage of 6.95% with highest yield of 351.46 qt/ha. However, it was at par with Spinosad 45 [email protected] ml/lit with fruit damage of 8.06% and yield of 341.75 q/ha.
