Root rot disease is widespread throughout bean growing areas in Samsun province. It was found, in this study, that the incidence of the disease was 92% and severity was 63% in Samsun. The most common fungi isolated from the infested root and soil samples were Fusarium spp., multinucleate Rhizoctonia solani (MNR) and binucleate Rhizoctonia-like fungi (BNR) and Fusarium species. Pythium spp. and Rhizoctonia group fungi were isolated also from the inner parts of the province and from the coastal area, while Pythium spp. were only isolated from the latter area. The great majority of the samples (59.4 %) yielded more than one fungi together, indicating that the disease was mainly caused by the complex of fungi.
