Chiba Prefecture is the largest producer of calla lily (Zantedeschia rehmannii) in Japan. In 2011, root rot, leaf yellowing and stunted growth of calla lily occurred in Chiba Prefecture. A pathogen isolated from the diseased plants was identified as Pythium myriotylum based on cultural characteristics as well as molecular analysis of the nuclear ribosomal internal transcribed spacer (ITS) region. An inoculation test confirmed that the oomycete was the causal agent of the disease. This is the first report of the disease in Japan.
