In vitro seventeen antagonistic microorganisms were evaluated against phytopathogen Sclerotinia Sclerotiorum by dual culture techniques. After 3 days from incubation, the maximum growth inhibition of the tested pathogen was noticed by Coniothyrium minitans (75.83%) followed by Trichoderma hamatum (63.33%). Also, after 15 days, the highest reduction of mycelial growth of S. sclerotiorum came from C. minitans (91.11%) followed by T. hamatum (85.83%). In case of sclerotia germination, C. minitans and T. hamatum significantly inhibited sclerotia germination with 95.83 and 91.67% reduction, respectively.
