Bottle brush, Kaner, Jatropa and Ber were evaluated for their ability to inhibit mycelial growth
and production of sclerotia of Rhizoctonia solani at 5, 10, 15 and 20 per cent concentrations In
vitro. The results indicate that, Latjeera and Jatropa at 5 and 10 per cent concentration did not
inhibit the growth of Rhizoctonia solani whereas, Sadabahar, Ber, Kaner, Bottle brush at 5 per
cent concentration showed an insignificant inhibition and rest all treatments at all concentration
inhibited a significant mycelial growth of the test fungus. It was also observed that inhibition
was directly proportional to the concentration of the extract. Maximum inhibition was recorded
in Eucalyptus (80%) followed by Neem (73%), Castor (69%), Bhang (56%) at 20 per cent
concentration. Finding in this study indicates utility extracts of plant in managing plant diseases.
