Characterization of Rhizoctonia species causing root-rot of cucumber plants grown in greenhouses in Samsun, Turkey

Abstract

Root-rot disease of cucumber plants is widespread and causes severe damage in the greenhouses in Samsun province. Rhizoctonia solani and binucleate Rhizoctonia-like fungi were isolated from the diseased cucumber plants. Cultural characterization, anastomosis grouping and pathogenicity of the isolates were determined. It was found that the most common group associated with the diseased cucumber plants was Rhizoctonia solani AG-4.
