Epidemiology of bean (Phaseolus vulgaris) web blight (BWB) caused by Thanatephorus cucumeris (teleomorph of Rhizoctonia solani) was studied in a field with a history of severe incidence of the disease. Sclerotia and mycelium of T. cucumeris, either free in soil or in the form of colonized debris,...

Mulching was highly effective and superior to chemical treatments for the control of web blight (WB) caused in beans by Rhizoctonia solani, the imperfect state of Thanatephorus cucumeris. Plots were established in fields with a history of repeated incidence of WB. Soilborne sclerotia and colonize...
