Abstract:

The pathogen, Rhizoctonia solani has a wide host range infecting crops and weed plants. In order to find out the host range of R. solani causing rice sheath blight, 26 plant species were selected which are commonly found in rice growing ecosystem. These plant species belonging to six families were grown and inoculated with fungus in glasshouse condition. Twenty five plant species found infected and one plant species devoid of infection. Diseased tissues of plants species belong to family Graminaceae, Cyperaceae produced typical symptoms of sheath blight. The fungus produced typical root rot and bark peeling symptoms in plant species belongs to family, Leguminaceae, Malvaceae, Amaranthaceae, The fungus not able to infect one weed species belongs to family Fabaceae, Indian joint vetch (Aeschynomene indica).


Keywords: Rice, Rhizoctonia solani, Sheath blight, Weeds, Sclerotia, Host range.
