Abstract:
Ganoderma species are important wood decaying fungi distributed throughout the world. They are diverse in the tropics affecting plantation crops such as coconut, arecanut and oil palm and they also affect ornamental, forest and avenue trees in tropical and temperate areas causing Basal Stem Rot/Ganoderma wilt. In present study, the Ganoderma spp. was isolated from basal stem rot disease of Gulmohar and different bio control agents viz., Trichoderma asperellum, T. Harzianum, T. Virens, Paecilomyces lilacinus, Metarrhizium anisopliae, Verticillium lecanii, Aspergillus Niger were tested in vitro against Ganoderma spp. Among these bioagents, highest mycelial growth inhibition of test pathogen was obtained with Trichoderma asperellum (50.74%) over untreated control which was followed by Trichoderma harzianum (47.03%), Trichoderma virens (41.48%), Aspergillus Niger (36.99%) and Paecilomyces lilacinus (17.40%), whereas, Metarrhizium anisoplie (15.92%) and Verticilium licani (14.07%) were found less effective against Ganoderma spp.
