In vitro Evaluation of Fungicides and Biocontrol Agents against Rhizoctonia solani in Tomato

Twenty four fungal biocontrol agents and twelve bacterial biocontrol agents were screened for their efficacy against phytopathogenic fungi Rhizoctonia solani through dual culture technique. Trichoderma harzianum-1 and Pseudomonas fluorescence-2 were found effective in inhibition of mycelium (62.53, 62.20) of Rhizoctonia solani under in vitro conditions. Ten fungicides were tested for their efficacy against Rhizoctonia solani through poisoned food technique and the ten fungicides Tebuconazole + Trifloxystrobin, Propiconazole, Captan + Hexaconazole and Carbendazim were record 100 per cent at recommended and half the recommended dosage under in vitro condition.
