Abstract
In 1982 and 1983, eyespot or foot rot of winter wheat, which has not been reported in Japan, was found at first in the Hachirogata reclaimed land in Akita prefecture. The brown and elliptical or “eye” shaped lesions formed on basal leaf sheaths and culms were most diagnostic. The severely infected culms were easily lodged by the wind. The causal fungus was frequently isolated from the diseased tissues and was identified as Pseudocercosporella herpotrichoides (Fron) Deighton based on the morphological characteristics of conidia produced on a dead tiller and on culture medium.
