Abstract:
Compatibility of B. bassiana was studied in the laboratory condition with five commonly used insecticides with their three doses by poison food technique. It showed that the carbosulfan 25 EC @ 0.017%, acetamiprid 20 SP @ 0.004%, fipronil 5 SC @ 0.004% and lambda cyhalothrin 5 EC @ 0.001% at lower dose was rated as relatively harmless (Grade 1) and it compatible with B. bassiana, while carbosulfan 25 EC @ 0.050% at higher dose and acetamiprid 20 SP @ 0.008% and fipronil 5 SC @ 0.008% at recommended dose were “slightly harmful” (Grade 2) to B. bassiana. Imidacloprid 17.8 SL @ 0.009%, acetamiprid 20 SP@ 0.012%, fipronil 5 SC @ 0.012% and lambda cyhalothrin 5 EC @ 0.004% at higher dose were found “moderately harmful” (Grade 3) and lambda cyhalothrin 5 EC @ 0.004% at higher dose showed “harmful” (Grade 4) to growth of B. bassiana.
