Symptomatic leaf samples were collected from potato plants in the main potato-growing regions of Iran, and isolations were made onto PDA medium. Single spore isolates were identified as <em>Ulocladium atrum </em>on the basis of morphological characteristics, and the identification was confirmed by sequence analyses of the ITS, <em>gpd</em> and Alt a1 gene regions. Pathogenicity tests demonstrated that <em>U. atrum</em> caused leaf blight on potato. This is the first report of leaf blight caused by <em>U. atrum</em> on potato in Iran.</p> ER -
