Contribution to the identification of Cercospora species in Iran

Eight species of the genus Cercospora from different localities in Northern provinces of Iran were obtained and examined during spring-autumn 2010. Cercospora acnidae (from Amaranthus chlorostachys var. chlorostachys), C. beticola (from Beta vulgaris), C. iridis (from Iris sp.), C. lactucae-sativae (from Lactuca sativa), C. mercurialis (from Mercurialis annua), C. sorghi (from Sorghum halepense) and C. zonata (from Vicia faba) were identified. Furthermore, C. apii is identified from Abutilon theophrasti, Euphorbia heterophylla, Solanum lycopersicum, Pelargonium zonale, Vigna sinensis and Zanthedeschia aethiopica. Among these, C. acnidae, C. apii, C. iridis, and C. mercurialis are new records and Sorghum halepense is new host for C. sorghi in Iran.
