摘　　要：[Objective]The aim was to isolate and identify the pathogen causing black spot disease in guava（Psidium guajava）,so as to determine its taxonomic status.[Method]The fungus was identified by determining its pathogenicity,observing its morphology characteristics and analyzing its ITS sequence.[Result]The pathogen causing black spot disease in guava was a strain of Guignardia mangiferae.[Conclusion]This study will provide theoretical basis for curing black spot disease of guava.[目的]从送检番石榴样品上发现一种黑斑病,对病原真菌的分离鉴定,明确其分类地位及重要性。[方法]通过致病性测定、形态学观察和ITS序列分析对病菌进行了鉴定。[结果]形态学观察和ITS序列分析表明病原菌为芒果球座菌(Guignardia mangiferae)。[结论]引起番石榴黑斑病的病原菌为芒果球座菌(G.mangiferae)。此前还未有G.mangiferae引起番石榴病害的报道。
