Abstract:
The present field investigation was carried out against pod borer [Helicoverpa armigera (Hubner)] on chickpea. The experiment was conducted in rabi 2021-22 at Central Research Farm, SHUATS, Naini, Prayagraj district. The field laid in RBD with seven treatment and one controlled plot. The result of the efficacy of treatment Chlorantraniliprole 18.5% SC 0.5ml/lit (84.32%) found to be most effective. Followed by Spinosad 45% SC 0.5ml/lit (79.57%), Nisco sixer plus 1ml/lit (73.87%), Bacillus thuringiensis 5ml/lit (68.88%), HaNPV 1ml/lit (60.09%), Beauveria bassiana 4ml/lit (54.63%), and the Neem oil 3ml/lit (47.74%) found to be least effective in reducing the larval population of Helicoverpa armigera but comparatively superior over the control. In another parameter higher yield was recorded in Chlorantraniliprole 18.5% SC (27.08 q/ha) followed by Spinosad 45% SC (24.58 q/ha), Nisco sixer plus (21.66 q/ha), Bacillus thuringiensis (17.50 q/ha), HaNPV (15.83 q/ha), Beauveria bassiana (14.83 q/ha) and Neem oil (12.08q/ha) as compared to control (10.83q/ha). The highest cost benefit ratio was obtained in the treatment of Chlorantraniliprole 18.5% SC (1:3.35), followed by Spinosad 45% SC (1:3.06), respectively.
