摘要
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.
