In 1976-1977, a Phytophthora stem rot of adzuki-bean (Phaseolus angularis) was discovered in Hokkaido, and the causal fungus was identified as P. vignae Purss. On the stem of adzuki-beans the characteristic lesions with reddish-brown streak appeared, and the affected plants finally wilted and blighted. The pathogen attacked only three cultivars of adzuki-bean and could not invade 14 another plants tested.
