Field Efficacy of Different Insecticides Against Brinjal Shoot and Fruit Borer, Leucinodes orbonalis (Guenee)

Abstract

The experiment was carried out at the research plot of the Department of Agricultural Entomology and Central Research Farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, during Kharif from July to November 2022 in Randomized Block Design (RBD) with three replications. Eight treatments were evaluated against, Leucinodes orbonalis i.e., Spinosad 45% SC (0.5ml/L), Chlorantraniliprole 18.5% SC (0.5ml/L), Flubendiamide 480 SC (0.4ml/L), Emamectin benzoate 5 SG (0.4gm/L), Indoxacarb 14.5% SC (0.25ml/L), Neem oil 5% (50ml/L), Beauveria bassiana (1X108 CFU/gm) 1.15 % WP (2.5gm/L), Control in RBD with three replications. The data on the percent infestation of shoot and fruit borer on brinjal 3rd, 7th, and 14th day after first and second spray reveal that all the chemical treatments were significantly superior over control. The lowest infestation was recorded in Chlorantraniliprole 18.5% SC (12.45) (9.78), Spinosad 45% SC (13.56) (10.43), Emamectin benzoate 5 SG (14.68) (11.39),
 Indoxacarb 14.5% Sc (15.34) (12.38), Flubendiamide 480 SC (16.26) (13.30), Beauveria bassiana
 (1X108 CFU/gm) 1.15% WP (16.84) (14.56), Neem oil 5% (19.46) (15.52). The best yield and most economical treatment was Chlorantraniliprole 18.5% SC (220.5q/ha) (1:8.3) which was par with Spinosad 45% SC (195.30q/ha) (1:7.7) followed by Emamectin benzoate 5 SG (172.50q/ha) (1:6.8), Indoxacarb 14.5 SC (165.35q/ha) (1:6.5), Flubendiamide 480SC (142.33q/ha) (1:5.3), Beauveria bassiana (1X108 CFU/gm) 1.15 % WP (130.40q/ha) (1:5.2) and Neem oil 5% (125.50q/ha) (1:5.04) as compared to control (90.00q/ha) (1:3.72). The yields among the treatment were significant.
