Rhizoctonia solani AG-4 HG-Iによるケール苗立枯病（新称）

抄録

Damping-off of kale (Brassica oleracea L., Acephala group) was found in Iwata, Shizuoka, Japan in 2016. Isolates obtained from basal stems with typical symptoms were identified as Rhizoctonia solani AG-4 HG-I. Original symptoms were reproduced on healthy kale seedlings after inoculation with the isolates, and inoculated fungi were reisolated from the diseased plants. This is the first report of kale damping-off caused by R. solani in Japan; therefore, we refer to this new disease as “damping-off of kale”.
