Bioassays of chlorantraniliprole 4.3% + abamectin against 1.7% SCSpodoptera litura(F.) andTetranychus urticae(Koch) on tomato

Abstract

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.
