To Evaluate The Bioefficacy Of Several Insecticides Against The Brinjal Shoot AndFruit Borer (Leucinodes Orbonalis Guen.)

Abstract

During Kharif 2022, an experiment was carried out in the brinjal field (Cultivar- Makra) at the Central Research Farm of Bidhan Chandra Krishi Viswavidyalaya, Gayeshpur, Nadia, West Bengal, to investigate the field efficiency of several pesticides against the brinjal shoot and fruit borer. Nine treatments (including control) i.e., Diflubenzuron+Deltamethrin 20% WP + 2% SC @ 2.25 ml/3L, Spinosad 45 SC @ 0.1ml/3L, Indoxacarb 14.5 SC @ 0.3 ml/3L, Diflubenzuron 25% WP @ 2.4 ml/3L, Deltamethrin 2.8% EC @ 2.13 ml/3L, Cypermethrin+Quinalphos 3%+20% EC @ 3.6 ml/3L, Deltamethrin+Triazophos 1% WP+35% EC @ 7.5 ml/3L, Emamectin Benzoate 5 SG @ 0.20 ml/3L were imposed with three replications in RBD. All the insecticidal treatments were significantly superior to the untreated control. Spinosad 45 SC was discovered to be the best-performing pesticide treatment against shoot and fruit borer with the lowest percentage of fruit loss (10.04%). Deltamethrin 2.8% EC was the poorest effective treatment when compared to the other treatments because it generated the highest fruit destruction (13.88%). In terms of yield Spinosad 45 SC performed well than all other treatments (227.05 q/ha) and Deltamethrin 2.8% EC was the lowest (176.10 q/ha).
