Abstract
The annual yield loss due to insect pests has been estimated at 30 per cent in black gram. As black gram is a short-duration crop, farmers primarily rely on pesticides for the management of insect pests. Hence, the present study was undertaken to evaluate the efficacy of a novel insecticides viz., chlorantraniliprole 18.50% SC, Novaluron 05.25%+ Indoxacarb 04.50% SC, Thiodicarb 75% WP, Emamectin benzoate 5% SG, Spinetoram 5.66% + Methoxyfenozide 28.3% SC, Flubendiamide 20% WG (Check) and Untreated control against lepidopteron pests in blackgram under field conditions during kharif - 2022 and 2023 at ARS, Bidar and ZARS, Kalaburagi, Karnataka.. Among the different insecticides evaluated, Chlorantraniliprole 18.50 % SC @ 0.2 ml/l and Novaluron 5.25% + Indoxacarb 4.5% SC @ 1.75 ml/l were proven to be the best treatments for the management of lepidopteron pests in black gram with an increase in the yields.
