Induction of Sexual Stage and Colony Morphology of Some Isolates ofSclerotium rolfsiiCausing Spotted Leaf Rot in Plants

“…Tu and Kimbrough (1978) described Athelia rolfsii (Curzi) Tu & Kimbrough as the perfect stage of S. rolfsii while studying Rhizoctonia-Sclerotium complex which is the currently accepted binomial for the sexual stage of S. rolfsii (Punja et al, 1982). Basidial stage of S. rolfsii has been reported as of infrequent occurrence in nature (West, 1947; Ghosh and George, 1955; Kulkarni and Ahmed, 1967) but can be induced in culture (Goto, 1930; Mundkur, 1934; Misra and Haque, 1960; Ahmed and Kulkarni, 1966; Kulkarni and Ahmed, 1967; Ahmed et al, 1966; Punja et al, 1982; Singh et al, 1996). Singh et al (1996) were able to induce sexual stage of this fungus within a week on Cyperus rotundu s rhizome powder supplemented water agar medium.…”
