Bioassays of chlorantraniliprole 4.3% + abamectin against 1.7% SC Spodoptera litura (F.) and Tetranychus urticae (Koch) on tomato

Bioassays were conducted with chlorantraniliprole 4.3% + abamectin 1.7% SC against tomato fruit borer Spodoptera litura (F.) and Tetranychus urticae (Koch). The results revealed that LC₅₀ of chlorantraniliprole 4.3% + abamectin 1.7% SC, abamectin 1.9 EC, lamda cyhalothrin 4.9 CS and chlorantraniliprole 18.5 SC by leaf dip bioassay to T. urticae was 1.018, 0.084, 2.029 and 6.938 ppm, respectively. The LC₅₀ for chlorantraniliprole 4.3% + abamectin 1.7% SC, chlorantraniliprole 18.5 SC, abamectin 1.9 EC and lamda cyhalothrin 4.9 CS to S.litura by topical application was 0.572, 1.740, 1.357 and 2.009 ppm, respectively.
