New records of powdery mildew fungi on landscape and ornamental plants from Iran
The Erysiphaceae are obligatory and biotrophic fungal parasites that infect many landscape and ornamental plants which results in reduction of beauty and marketability of these plants. This study was performed to identify powdery mildew fungi on landscape and ornamental plants in four provinces (Isfahan, Chaharmahal & Bakhtiari, Markazi and Lorestan) of Iran. Consequently, 24 powdery mildew taxa on 28 host species were collected during 2017 to 2019. According to our findings,Golovinomyces asperifolii (on Nonea sp.) and Podosphaera euphorbiae-helioscopiae (on Pedilianthus sp.) are new records to Iran mycobiota. Three plant species including Coreopsis sp., Catharanthus roseus and Fragaria vescaare new hosts for powdery mildew fungi of Iran. Moreover, Podosphaera xanthii on Dahlia sp. is reported for the first time from Iran.
