Out of 20 species, 6 species were dominantly isolated which were tested for antagonistic activity against plant pathogen Curvularia senegalensis. Of them Aspergillus ustus exhibited effective inhibitory activity against phytopathogen. Thus the results revealed that Aspergillus ustus was able to inhibit the growth of curvularia senegalensis to the maximum extent possible. The bioactive compounts of Aspergillus ustus have been analyzed by using Gas chromatography mass spectrometry.
