米兰炭疽病是米兰的主要病害之一,多发生在从广东引种到北方的苗株及栽植后的缓苗期,病害发展迅速,造成大量毁株。根据病原菌的形态、培养性状、致病性及寄主范围鉴定为围小丛壳菌[Glomerella cingulata(Stonem.)Spauld.et Schrenk],分生孢子阶段为盘长孢状刺盘孢(Colletotrichumgloeosporioides Penz.)。该菌在米兰上寄生迄今未见报导。 Anthrax in Milan is one of the main diseases in Milan, mostly occurred in Guangdong Province introduced to the north of the seedlings and seedling after the seedling stage, the rapid development of disease, resulting in a large number of destroyed strains. According to the morphology of the pathogen, the characters of culture, pathogenicity and host range were identified as Glomerella cingulata (Stonem.) Spauld.et Schrenk. The conidial stage was Colletotrichum gloeosporioides Penz. ). The bacterium parasitic in Milan so far has not been reported.
