 ABSTRACT

An experiment was conducted with twenty-four fungal biocontrol agents and twelve bacterial biocontrol agents were screened for their efficacy against phytopathogenic fungi Sclerotium rolfsii through dual culture technique. The T. harzianum -1 and P. f-3 were found effective in inhibition of mycelium (95.1, 60.80) against Sclerotium rolfsii under in vitro conditions. Ten fungicides were tested for their efficacy against Sclerotium rolfsii tthrough poisoned food technique and the ten fungicides Mancozeb,  Tebuconazole + Trifloxystrobin, Metiram + Pyraclostrobin, Cymoxanil + Mancozeb, Propiconazole and Captan + Hexaconazole were record 100 per cent at recommended and half the recommended dosage under in vitro condition.

Key words:Biocontrol agents, T. harzianum, Pseudomonas fluorescence, Fungicides, Sclerotium rolfsii, Tomato.
