近年来,在日本青森县各地苹果贮藏期间普遍发生一种果实疫病,尤其在11月以后采收的富士、王林、陆奥等晚熟品种上发病严重。经鉴定,其病原菌为丁香疫霉Phytophthora syringae。与欧洲报导的结果相一致,而与日本过去记载的果实疫病病原菌恶疫霉(Phytophthora cactorum)不同,是一种新的苹果疫病。 In recent years, a fruit epidemic occurs frequently during the storage of apples throughout Aomori Prefecture in Japan. In particular, late maturing varieties such as Fuji, Wang Lin and Mutao, which were harvested after November, have been severely ill. It has been identified that the pathogen is Phytophthora syringae. In line with the results reported in Europe, it is a new apple blight, unlike the Phytophthora cactorum, a fruit-blown pathogen previously reported in Japan.
