Abstract
Beauveria bassiana (Bals.) Vuill., a facultative entomopathogenic fungus with a broad host range and notable host specificity, is one of the insect pathogens studied. Environmental variables, biopesticides, and chemical products used to protect crop plants affected the survival of its conidia. This study evaluated the fungus's compatibility with five fungicides, five herbicides and five insecticides with four replications of each treatment. Two concentrations of each pesticide formulation were tested (Recommended and higher dose). The results showed that selectedall fungicides, all herbicides and some of the insecticides were completely or significantly inhibited the development of B. bassiana and were incompatible with the fungus. The insecticide flonicamid, on the other hand, was found to be highly compatible with B. bassiana at recommended dose onlywhich showed 21.06 per cent mycelial growth inhibition as compared to control. This combination could have been effectively employed only at recommended dose only in integrated pest management strategies.
