Severe wilt was found on seedlings of turnip green (Brassica rapa L., perviridis group) in Ibaraki Prefecture, Japan, from May to September 2013. A fungus repeatedly isolated from diseased plants was identified as Rhizoctonia solani AG-4 HG-III based on culture morphology, anastomosis and sequencing of the internal transcribed spacer region on ribosomal DNA (rDNA-ITS region). Pathogenicity of this isolate to turnip green was confirmed based on inoculation test. Because Rhizoctonia blight of turnip green by AG-4 HG-III has not been reported so far, we propose including it as one of the pathogens causing this disease. © 2015, The Phytopathological Society of Japan and Springer Japan.
