草莓枯萎病菌是草莓上的检疫性病原真菌,对草莓的品质和产量产生极大的影响,在口岸上是进境草莓种苗重要的检疫项目。应加强进境草莓种苗的检疫,以防止该病菌传入国内,本文对草莓枯萎病菌的分类地位、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。

Fusarium oxysporum f.sp.fragariae is a quarantine fugus of strawberry, can damage the quality and cause huge output lost of host. This fugus has been considered as an important quaranine item in imported strawberry seeding. So to strengthen the quarantine activity of imported strawberry seeding can prevent the spread of fugus from abroad. This paper will briefly describe the taxonomic status, host, distribution, symptoms of damage, biological characters and quarantine diagnosis of F. oxysporum f.sp.fragariae.
