In September 2019, Pythium rot of ornamental cabbage (Brassica oleracea L. Acephala Group) occurred in Kinokawa City, Wakayama Prefecture, Japan. The causal agents were identified as Pythium aphanidermatum and P. myriotylum based on cultural characteristics and molecular analysis of ribosomal DNA internal transcribed spacer (rDNA-ITS) regions. An inoculation test confirmed that oomycetes were the causal agents of the disease. This is the first report of Pythium rot in ornamental cabbage in Japan.
