Efficacy of Novel Insecticides for the Management of Brinjal Shoot and Fruit Borer (Leucinodes orbonalis L.)

Abstract

The investigation was conducted at the field experiment farm of R.B.S. College, Bichpuri, Agra, during the Kharif season of 2022-23, selected for its historical prevalence of Leucinodes orbonalis infestations in brinjal crops. The study utilized the brinjal variety Golden Gem. A selection of novel insecticides was tested, including Insecticide T1 (Cypermethrin 25% EC 2 ml/lit), T2 (Spinosad 45% SC 0.20 ml/lit), T3 (Flubendiamide 20% WG 0.75 ml/lit), T4 (Azadirectin 0.03% EC 5 ml/lit), T5 (Emamectinbenzoate 5% EC 0.5 ml/lit), T6 (Lambdacyhalothrin 2.5% EC 1 ml/lit), T7 (Chlorantranilipole 18.5% SC 0.4 ml/lit) and T8 (Control). Thus, all eight treatment combinations were compared in a randomized block design (RBD) with three replications. Results indicated that Flubendiamide achieved the highest reduction in pest incidence (75.30%), followed by Emamectin benzoate (59.41%) and Indoxacarb (57.09%). The findings underscore the potential of these novel insecticides as effective alternatives to traditional chemical controls, contributing to integrated pest management strategies that minimize environmental impact while enhancing brinjal production.
