Abstract: The soil-borne pathogen Sclerotium rolfsii Sacc., which causes wilt disease, is one of the diseases that most frequently infest betelvine (Piper betle Linn.). The goal of the current study was to assess the inhibitory effects of four antagonistic biocontrol agents and aqueous extract of eight different plant species of plants under in vitro condition for their inhibitory effect on mycelial growth of S. rolfsii. Among the plant extracts tested at three different concentrations, 15 per cent concentration of all plant extracts were significantly found superior to 5 and 10 per cent. At 15 per cent concentration of plant extracts, maximum 62.19 per cent inhibition of mycelial growth was recorded in tulsi leaf extract followed by marigold leaf extract (57.11%). Among the biocontrol agents tested Trichoderma harzianum I showed maximum antagonistic effect and found to be significantly superior in inhibiting the mycelial growth of S. rolfsii (62.64%).
