The results showed that indoxacarb 14.5% SC and abamectin 1.9% EC were found to be most effective in reducing larval population of Spodoptera litura and Spilosoma obliqua whereas, indoxacarb 14.5% SC and emamectin benzoate 5% WG were found significantly better to reduce larval population of Trichoplusia ni. The treatments of emamectin benzoate 5% WG and indoxacarb 14.5% SC were found the most effective in reducing the pod borer damage with high grain yield of black gram.
