Effect of Plant Extract on the Growth of Sclerotinia sclerotiorum

At 5% concentration the minimum radial growth (14.0 mm, 37.0 mm and 66.5 mm) was observed in leaf extract of Jatropha after 48,72 and 96 hours, respectively. The leaf extracts of Xanthium, Madar, Parthenium and Pudina were next best effective plant extracts, which showed 17.5 mm,19.5 mm,22.5 mm and 24.0 mm radial growth, respectively. Lantana was least effective plant extract, which showed the maximum radial growth 35.0 mm, 69.0 mm and 90.0 mm after 48,72 and 96 hours, respectively. Maximum number of sclerotia (30) were formed in the leaf extract of Madar and minimum number (15.00) were formed in Lantana leaf extract. Similar patterns were observed in the radial growth of Sclerotinia sclerotiorum in 10% concentration
