A study assessed the toxicity of insecticides on mycelial growth and spore production of Beauveria bassiana by poisoned food technique. Among the insecticides tested, profenophos 50 EC was the most toxic to mycelial growth and conidial germination followed by thiamethoxam 25 WG. Dimethoate 30 EC showed complete inhibition of vegetative growth and sporulation of the fungus at all the doses. On the contrary, imidacloprid 17.8 SL and neem oil 3% were significantly compatible and were found safe to conidial germination and growth.
