Abstract:
The Banyan (Ficus benghalensis) is the National tree of India which belongs to Family Moraceae. It is used as the medicinal as well as ornamental plant and is also called as Vad, Bargad and Banyan in India. In some plants rhizospheric activities stimulate the microflora which helps in disease management as well as plant development. Present investigations were conducted to study in vitro antagonistic ability of the microflora isolated from the rhizospheric soil of banyan tree against Sclerotium rolfsii. The antifungal activity against Sclerotium rolfsii treatment T8 (Pseudomonas striata) found most effective showed highest zone of inhibition i.e. 74.44%. On comparision with bioagents of VNMKV Parbhani, isolated strins of Pseudomonas fluorescence (73.25%), Pseudomonas striata (73.92%) and Bacillus subtilis (74.44%) are better over the available strains of VNMKV i.e. Pseudomonas fluorescence (69.62%), Pseudomonas striata (72.84%) and Bacillus subtilis (72.21%) respectively. The isolated Trichoderma koningi (68.51%) was at par to the available strains of VNMKV Trichoderma koningi (68.51%).
