Abstract

A field experiment was conducted during kharif 2020 at Dhule ,Maharashtra (India) to determine efficacy of some insecticides, biopesticides and botanicals against shoot and fruit borer (Leucinodes orbonalis Guenee.) on brinjal (Solanum melongena L.). The efficacy result showed that the Emamectin benzoate 5% SG (10.35% and 15.91%) found most effective followed by Cypermethrin 25%EC (11.49 and 17.32%), Spinosad 45%SC (14.06 and 18.77%), NSKE 5% (15.43 and 20.31%), Bacillus thuringiensis var kurstaki 54% (15.96 and 22.30%) and Beauveria bassiana 1×108 CFU (16.53% and 23.45%) was next effective treatment. Among all the treatments Garlic Bulb extract 3% (17.15% and 24.69%) is found be least effective but comparatively superior over the control. The best and most economical treatment was Emamectin benzoate 5%SG (1:3.3), followed by Cypermethrin 25% EC (1:3.1), Spinosad 45% SC (1:2.6), NSKE 5% (1:2.5), Bacillus thuringiensis var kurstaki (1:2.4), Beauveria bassiana 1×108 CFU (1:2.1), Garlic Bulb extract 3% (1:1.9) as compared to control (1:1.1). Emamectin benzoate 5%SG (179q/ha) followed by Cypermethrin 25% EC (163q/ha).
