Abstract

Examination of pure culture of the pathogens collected from the root samples of soybean plants showing typical wilting symptoms revealed that the major pathogens involved in causing root rot complex are Sclerotium rolfsii Sacc. Rhizoctonia bataticola and Fusarium sp. in northern Karnataka. The pathogenicity studies on susceptible cultivar JS 335 inoculated with all the pathogens revealed maximum percent disease incidence in case of dual inoculation of S. rolfsii + R. bataticola (83.33%) and mixed inoculation of S. rolfsii + R. bataticola + Fusarium sp. (88.50%) followed by dual inoculation of Fusarium sp. + R. bataticola (75%) and S. rolfsii + Fusarium sp. (72.34%).
