Abstract:
A field investigation was carried out during Kharif season of 2021 at Crop Research Farm, Department of Entomology “Sam Higginbottom university of Agriculture, Technology and Sciences” Prayagraj, Uttar Pradesh. The experiment was laid in Randomized block design with seven treatments replicated thrice along with a control plot to check the Efficacy of selected insecticides against brinjal shoot and fruit borer (Leucinodes orbonalis Guenee). In the series of shoot infestation, the efficacy of treatments on first spray showed that chlorantraniliprole (7.87%) to be the most effective among the selected insecticides followed by flubendiamide (9.03%) and emamectin benzoate (11.84%). Treatments Spinosad (12.83%) and cypermethrin (15.00%) was found to be average. While lambda cyhalothrin (16.35%) and Azadirachtin (20.69%) was found to be less effective in controlling the infestation of Leucinodes orbonalis (Guenee). In the series of the fruit infestation, the efficacy of treatments on second spray showed that Chlorantraniliprole (8.30%) found to be most effective, followed by Flubendiamide (9.69%) and Emamectin benzoate (11.90%). Treatments Spinosad (13.91%) and Cypermethrin (16.55%) was found to be average. While Lambda cyhalothrin (18.25%) and Azadirachtin (20.64%) was found to be less effective in controlling the infestation of Leucinodes orbonalis (Guenee) but comparatively superior over the control.
