摘要

2018年夏季，在伊朗阿达尔市、查哈尔马哈尔和巴赫蒂亚里省的郊区收集了带有不规则或椭圆形小坏死斑点的薄荷叶。从患病组织中分离出一株真菌，根据形态特征和gpdh基因的部分序列，鉴定为双北极星(Bipolaris sorokiniana)。在致病性研究中，接种14天后，在叶片上观察到疾病症状。同样的病原体被重新分离并从患病的叶子中鉴定出来，从而实现了科赫的假设。这是伊朗和世界上首次报道白僵菌引起薄荷叶斑病的报道。

First report of Bipolaris sorokiniana, causing leaf spot on Mentha pulegium

Pennyroyal (Mentha pulegium) leaves with small irregular or ellipsoidal necrotic spots were collected in a suburb area of Ardal city, Chaharmahal and Bakhtiari province of Iran in summer 2018. A fungal isolate was recovered from diseased tissue and identified as Bipolaris sorokiniana based on morphological characteristics and a partial sequence of the gpdh gene. In a pathogenicity study, disease symptoms were observed on inoculated leaves after 14 days. The same pathogen was re-isolated and identified from diseased leaves, thus fulfilling Koch's postulates. This is the first report of B. sorokiniana causing leaf spots on Mentha pulegium in Iran and the world.
