核盘菌[Sclerotinia sclerotiorum(Lib.)de Bary]是一个在世界上广泛分布的重要病原菌。其寄主范围十分广泛,已报道的寄主植物分属于64科225个属中361种植物。据国内戴芳澜1979“中国真菌总汇”记载约有145种寄主植物。据杨新美1959年报道油菜菌核病的寄主71种植物。据李汉卿、傅纯彦1981年报道大豆菌核病共有85种寄主植物,分别属于20个科。1983～1988年作者通过广泛调查核盘菌的自然感病的寄主范围,发现除严重感染已报道的寄主向日葵,大豆,菜豆,茄子,辣椒,黄瓜,大麻,苍耳,黄蒿等(一般发病率5—80%),还发现能在自然条件下感染至今国内尚未见报道的17种新寄主。新寄主的名称是百
Sclerotinia sclerotiorum (Lib.) De Bary] is an important pathogen widely distributed in the world. The host range is very wide. The reported host plants belong to 361 species of 225 genera in 64 families. According to the domestic Dai Fanglan 1979 “China fungus confluence” records about 145 kinds of host plants. According to Yang Xinmei 1959 reported 71 host plants of rape sclerotinia. According to Li Hanqing, Fu Chunyan in 1981 reported that there were 85 kinds of host plants of sclerotinia, belonging to 20 families. From 1983 to 1988, through extensive investigation of the host range of natural susceptible strains of S. sclerotiorum, the authors found that in addition to host hosts such as sunflower, soybean, kidney bean, eggplant, pepper, cucumber, marijuana, cocklebur, Rate of 5-80%), but also found that in natural conditions have not been reported in the domestic infection of 17 new hosts. The name of the new host is one hundred
