Compatibility studies of different insecticides with entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin

Compatibility of Beauveria bassiana (Balsamo) Vuillemin was studied in the laboratory condition with ten widely used systemic insecticides with their three doses by poison food technique. The results showed that the dimethoate 30 EC was found the most compatible at lower, recommended, and higher doses, as it was categorized as harmless (Grade 1) to the fungus. Dinotefuran 20 SG at higher dose (0.005%) and carbosulphan 25 EC at all doses were categorized as harmful (Grade 4) to B. bassiana.
