Abstract:
Present research entitled “Evaluation of some newer insecticides against Helicoverpa armigera Hub. in pea (Pisum sativum L.)” was conducted during rabi-2022-23 at Research Farm, Post Graduate Institute, MPKV, Rahuri and comprised seven treatments viz., T₁-Spinosad 45% SC, T₂-Beauveria bassiana 1.15% WP, T₃-Flubendiamide 39.35% SC, T₄-Bacillus thuringiensis var. kurstaki, T₅-Azadirachtin 10000 ppm, T₆-Chlorantraniliprole 18.5% SC and T₇-Untreated control laid out in RBD with three replications. Based on the performance of different treatments, chlorantraniliprole was proved to be highly effective by recording lowest percent of pod damage (7.62%), the data was at par with flubendiamide by registering 7.79% pod damage. Spinosad (8.40% pod damage), azadirachtin (12.38% pod damage), Beauveria bassiana (12.72% pod damage), Bacillus thuringiensis var kurstaki (13.01% pod damage) were next to follow in the order of effectiveness. Untreated control recorded highest (25.69% pod damage) infestation. ICBR ratio was found highest in Beauveria bassiana (1:41.80) followed by Bacillus thuringiensis var. kurstaki (1:27.54), azadirachtin (1:26.20), chlorantraniliprole (1:25.68), flubendiamide (1:25.51), and spinosad (1:15.41), respectively.
