Abstract:
Present study revealed that all four bio-agents evaluated and exhibited antifungal activity against test pathogen (Alternaria polianthi) and significantly inhibited mycelial growth over untreated control. Out of four bio-agents, Trichoderma viride showed least mycelial growth of test pathogen (2.38 cm) and highest mycelial growth inhibition (70.31%) which was at par with Trichoderma harzianum with 2.78 cm mycelial growth and 65.31 per cent growth inhibition. While, Trichoderma koningii had maximum mycelial growth of test pathogen (3.88 cm) with minimum growth inhibition percentage (51.56%). Out of ten fungitoxicants evaluated, The fungicide Propiconazole 25% EC @ 0.1% showed maximum growth inhibition (97.92%) which was at par with Tebuconazole 25.9% EC @ 0.1%, Difenoconazole 25% EC @ 0.05% which reported 95.83 per cent and 95.00 per cent growth inhibition against test pathogen respectively.
