Abstract

The present experiment was conducted during Kharif season of 2022 at Central Research Farm (CRF) of Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. Total of two sprays were applied using eight treatments with three replications using Randomized Block Design (RBD), to evaluate the per cent infestation of shoot and fruit borer on brinjal. The results revealed that all the treatments were superior over the control against the infestation of brinjal shoot and fruit borer on third, seventh and fourteenth days after spraying. Among all the treatments, Chlorantraniliprole 18.5% SC @ 0.4ml/L was found to be the most effective treatment with (8.26%) infestation in shoot and (7.69%) infestation in fruit, followed by Emamectin benzoate 5% SG @ 0.4gm/L (14.19%) and (12.55%). The next best treatments were found to be Indoxacarb 14.5% SC @ 1ml/L (14.39%) and (13.67%), Chlorpyriphos 20 EC @ 0.25ml/L (17.42%) and (14.40%), Metarhizium anisopliae @ 2×108 CFU (18.16%) and (14.64%), Beauveria bassiana @ 2×108 CFU (19.40%) and (15.46%). Neem oil 2% @ 20ml/L (21.88%) and (16.41%) was found to be least effective. The highest yield and cost benefit ratio was recorded in Chlorantraniliprole 18.5% SC (210.6 q/ha) and (1:7.48) followed by Emamectin benzoate 5% SG (187.5 q/ha) and (1:6.88), Indoxacarb 14.5% SC (163.5 q/ha) and (1:5.87), Chlorpyriphos 20% EC (131.9 q/ha) and (1:4.82), Metarhizium anisopliae (121.5 q/ha) and (1:4.28), Beauveria bassiana (116.3 q/ha) and (1:4.13) and Neem oil 2% (104.2 q/ha) and (1:2.67).
