Abstract: The in vitro compatibility of the entomopathogenic fungus, Cladosporium cladosporioides BOU1, with the crude extract of three plants viz. Calotropis gigantea, Vitex negundo and Carissa macrocarpa at a concentration of 1% and 2% was investigated. The compatibility of the fungal isolate with the plant extracts was calculated using the biological index formula from the germination percentage, radial growth and spore production of BOU1. The compatibility of the plant extracts with the fungal isolate was also assessed based on the protease and lipase activities of the treated fungus. Both concentrations of plant extracts did not significantly inhibit the germination percentage, radial growth and spore production of BOU1 in a dose-depended manner. The average mean values of the biological index for the three plant extracts with two concentrations were more than 98%. The analyses of the data with the compatibility index formula suggest that irrespective of concentration, all three plant extracts were compatible with BOU1. When the plant extracts were added to the fungal isolate, the protease and lipase activities of the fungal isolate were not significantly inhibited compared to the untreated control. The reduction in all the variables of fungal growth and the enzymatic activity was less than 10% and 20%, respectively. From these findings, we can conclude that the fungal biocontrol agent C. cladosporioides BOU1 is compatible with the investigated plant extracts in terms of the fungal growth and enzymatic activities.
