Online published on 27 February, 2017. Abstract The medicinal plants used for their imperially antifungal properties. These natural resources with antifungal activity against different strains of fungus have been found, which great importance to environment and plants are. The inhibitory effect of extract from Bauhinia racemosa (apta), Caesalpiniabonducella (sagar gotta), Piper betle Linn were studied against Sclerotiumrofsii causing rot in chilli. In present studied the antifungal activity of medicinal plants leaves extract of different concentration were done by poisoning food technique. To determine their antifungal activity, different concentration of each plant extract of 10%, 25%, 50%, 75% and 100% (that is without treatment serve as control) of aqueous medium were tested against Sclerotium rolfsii. The higher inhibition effect of all extracts was recorded at 75 and 50 percent concentration of Piper betle Linn aqueous leaves extracts gave 54.70% & 52.98% if inhibition with 25.66mm & 24.33mm inhibited radial mycelium growth after 48 incubation period. The antifungal activity of Bauhinia racemosa (apta) had moderate, it showed 48.82% & 39.77% of inhibition with 28.66mm & 45.77mm inhibited radial mycelium growth after 48 & 72 hours of incubation respectively. The lowest inhibition 35.71% & 27.98% was recorded by Caesalpinia bonducella (sagar gotta) with 36mm & 27.98mm inhibited radial mycelial growth after 48 hours of incubation period. Result clearly indicates that these medicinal plants were used in this paper proved a promising source of antifungal compounds.
