The three entomopathogenic fungi viz., Beauveria bassiana (Bals.) Vuill., Metarhizium anisopliae (Metchnikoff) Sorokin and Verticillium lecanii were tested for their compatibility with three insecticides used in banana production system in in vitro by poinson food technique. All the insecticides were tested for their compatibility with each fungi at three different concentrations i.e., recommended dose (RD), half of the RD and one fourth of the RD. V. lecanii was found highly compatible with all the insecticides followed by B. bassiana. The concentration ¼ RD of all the insecticides was found safe showing higher mycelial growth of the fungi. Imidacloprid 17.8% SL at 0.025 % showed no inhibition (0.00 %) of V. lecanii followed by 9.81 per cent to B. bassiana. Dimethoate 30 EC at 0.05% showed maximum inhibition of 21.25 per cent of V. lecanii followed by 27.81 per cent to B. bassiana. The botanical insecticide Azadirachtin at 0.075% showed maximum inhibition of 22.94 per cent of V. lecanii followed by 35.19 per cent to B. bassiana. Present investigations showed effects of pesticides on the fungi, their actual effects at cellular and field level need to be investigated for the efficient utilization of entomopathogens in the integrated pest management of banana.
