甘蔗凋萎病菌是甘蔗上的检疫性病原真菌,对甘蔗的品质和产量产生极大的影响,在口岸上是进境甘蔗种苗重要的检疫项目。应加强进境甘蔗种苗的检疫,以防止该病菌传入国内,本文对甘蔗凋萎病菌的分类地位、寄主、地理分布、危害症状、生物学特性和检疫鉴定特征进行简述。 Sugarcane wilt pathogens are quarantine pathogenic fungi on sugarcane and have a great impact on the quality and yield of sugarcane. It is an important quarantine project on the entry of sugarcane seedlings at the port. The quarantine of sugarcane seedlings should be strengthened so as to prevent the bacteria from entering the country. This paper briefly introduced the taxonomic status, hosts, geographical distribution, hazard symptoms, biological characteristics and quarantine characteristics of sugarcane wilt pathogen.
