Since 1975, a new root rot disease of dasheen has been occurring at the various nursery beds in northern Chiba Prefecture. The disease was severe in high humidity and soil temperature. The infected plant with decayed roots was stunted, but its tubers remained relatively healthy. Although Pythium myriotylum and Rhizoctonia spp. were isolated from the infected roots, only Pythium myriotylum was pathogenic.
