Abstract:
An experiment entitled “evaluation of newer insecticides against stem fly and girdle beetle in soybean” was conducted at College of Agriculture, Warora Dist. Chandrapur in Randomized Block Design with seven treatments and three replications. The insecticidal treatment viz., Chlorantraniliprole 18.5% SC, Thiacloprid 21.7% SC, Indoxacarb 15.8% EC, Beta cyfluthrin 8.49% + Imidacloprid 19.81% 300 OD, Thiamethoxam 12.6% + Lambda Cyhalothrin 9.5% ZC, Chlorantraniliprole 10% + Lambda Cyhalothrin 5% ZC including control were evaluated during kharif 2021. The results showed that treatment with spraying of Chlorantraniliprole 10% + Lambda Cyhalothrin 5% ZC @ 150 ml/ha found to be most effective in minimizing the stemfly infestation (1.65%), with maximum seed yield. Whereas, the highest incremental cost benefit ratio was obtained in treatment of Thiamethoxam 12.6% + Lambda Cyhalothrin 9.5% ZC @ 125 ml/ha (1:16.36) followed by Beta cyfluthrin 8.49% + Imidacloprid 19.81% 300 OD @ 350 ml/ha (1:11.12).
