Abstract:
A laboratory experiment was conducted to study the antifungal activity of plant extracts and antagonistic activity of bio control agents against Sclerotium rolfsii Sacc. inciting agent of betelvine wilt complex disease. Among the botanicals evaluated maximum per cent inhibition (85.00 %) of mycelial growth was recorded in the combination of garlic bulb extract, black tulsi leaf extract and rhizome extract of turmeric (1:1:1) at 15 per cent concentration. Among the fungal and bacterial bio control agents tested, T. harzianum (IOF isolate) and T. harzianum (Kakol isolate) were effective in inhibiting S. rolfsii with 71.33 and 70.37 per cent respectively, which were statistically on par with each other.
