Rape plants (
Brassica napus), which are cultivated for their edible shoots, developed damping-off in Tsu city, Japan, in November 2007.
Rhizoctonia solani AG-2-1 was isolated from the diseased seedlings, and the pathogenicity of the isolate was confirmed. Mycelial growth in culture on potato dextrose agar was optimal at 20°C. This is the first report on the disease of rape caused by
R. solani in Japan.
