アスパラガスの斑点病

抄録

Stemphylium sp. was isolated from the lesions of asparagus plants in Hokkaido. The early symptoms on stems and cladophylla are spots which are light brown to gray in the center with red brown margin, 2-5×3-12mm. in diameter and the cladophylla defoliate later. The fungus is identified to be S. botryosum Wallr. and the author proposes the name of asparagus Hanten-byô (Stemphylium leaf spot).
