Abstract:
A field investigation was conducted to evaluate field evaluation of chemicals and bio-pesticides against chickpea pod borer [Helicoverpa armigera (Hubner)] at Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. The result revealed that insecticides were effective against pod borer even if they have slight per cent pod damage. Among all the treatments lowest per cent pod damage was recorded in T₄-Spinosad 45 SC (5.07%) followed by T₁-Chlorantraniliprole 18.5% SC (6.37%), T₂-Flubendiamide 480% SC (7.50%), T₃-Emamectin benzoate 05.00% SG (8.80%), T₆-Nisco sixer plus (10.16%), T₅-HaNPV (11.34%). T₇-Bacillus thuringiensis (11.93%) which is statistically found be least effective but significantly superior over the control. The highest yield was recorded in Spinosad 45 SC (22.90 q/ha) followed by Chlorantraniliprole 18.5% SC (21.40 q/ha), Flubendiamide 480 SC (20.20 q/ha), Emamectin benzoate 05.00% SG (18.03 q/ha), Nisco sixer plus (17.45 q/ha), HaNPV (13.70 q/ha) and Bacillus thuringiensis (12.40 q/ha) as compared to control (9.10 q/ha). When cost benefit ratio was worked out, interesting result was achieved. The cost effectiveness of Spinosad and Chlorantraniliprole was also high and very favourable with incremental cost-benefit ratios of 1:2.92 and 1:2.81 respectively, followed by Flubendiamide (1:2.51), Emamectin benzoate (1:2.47), Nisco sixer plus (1:2.28), HaNPV (1:187) and Bacillus thuringiensis (1:1.68).
