Abstract
The present field investigation was carried out in the Prayagraj district of Uttar Pradesh. The experiment was conducted in Kharif season 2023-2024 at Central Research Farm (CRF), SHUATS, Naini, Prayagraj district. The field layout chosen was RBD with seven treatments and controlled plot. To check the “Efficacy and economics of selected insecticides against pod borer, Helicoverpa armigera (Hubner) on cowpea Vigna ungiculata (L.) Walp”. The result of the efficacy of the treatments after first spray showed that the Chlorantraniliprole (1.66) found out to be most effective. Followed by Spinosad (1.95) and Indoxacarb (2.22). Treatments Imidacloprid (2.33) and Fipronil (2.44) was found to be average. Bacillus thuringiensis (2.55) and Azadiractin (Neem Oil ) (2.64) found to be less effective in managing the larval population of Helicoverpa armigera. According to the second spray of showed that Chlorantraniliprole (1.02) was found to be the most effective. Followed by Spinosad (1.42) and Indoxacarb (1.64). Treatments Imidacloprid (1.95) and Fipronil (2.1) was found to be average. Bacillus thuringiensis (2.31) and Azadiractin (Neem oil ) (2.44) found out to be less effective in managing the larval population of Helicoverpa armigera but comparatively superior over control. In another parameter higher yield was recorded in Chlorantraniliprole (24.08 q/ha) followed by Spinosad (22.50 q/ha), Indoxacarb (17.20 q/ha), Bacillus thuringiensis (13.70 q/ha) and Azadiractin (Neem oil ) (12.60 q/ha) as compared to control (10.50 q/ha). The highest cost benefit ratio was obtained in treatment of Chlorantraniliprole (1:3.51), followed by Spinosad (1:2.85), respectively.
