Abstract

Barley (Hordeum vulgare) is an important crop in Turkey. In this study, 37 barley fields in Batman central district and Beşiri (Batman), Gercüş (Batman), Hasankeyf (Batman), Kozluk (Batman), Sason (Batman), Kocaköy (Diyarbakır), Kurtalan (Siirt), and Midyat (Mardin) districts were examined for the presence of leaf diseases. In addition, 24 naturally grown wild barley (H. spontaneum) populations in Batman central district and Beşiri, Hasankeyf, Kurtalan, and Midyat districts were inspected for the presence of leaf diseases. In barley fields, scald caused by Rhynchosporium commune was the most common disease, followed by the spot form of net blotch caused by Drechslera teres f. maculata, barley stripe caused by Drechslera graminea, the net form of net blotch caused by Drechslera teres f. teres, spot blotch caused by Cochliobolus sativus, powdery mildew caused by Blumeria graminis f. sp. hordei and brown rust caused by Puccinia hordei. Among the Hordeum spontaneum populations the most common disease was scald, followed by the spot form of net blotch, the net form of net blotch, powdery mildew, and brown rust.
