Seven different fungicides were tested against colony growth of Rhizoctonia bataticola and Sclerotium rolfsii. Among all the fungicides tested, hexaconazole 5% SC, tebuconazole 250 EC, vitavax power 75% WP at all concentrations recorded maximum inhibition (100%) against Sclerotium rolfsii and against Rhizoctonia bataticola. The per cent inhibition ranged from 97.7 to 100 per cent. Among different Trichoderma isolates tested, significant reduction of radial growth of Rhizoctonia bataticola and Sclerotium rolfsii was recorded by isolates CT7 and CT8.
