DOI : 10.21566/tarbitderg.581079 Viewed : 1336 - Downloaded : 840 Barley growing areas of Elazığ province of Turkey were surveyed during the period of May and June of 2018 and barley leaf diseases were determined. Surveys included Elazığ central district and Karakoçan, Palu, Arıcak, Kovancılar, Keban, Ağın, Baskil, Sivrice and Maden districts. Following diseases were recorded; spot form of net blotch caused by Drechslera teres f. maculata, net form of net blotch caused by Drechslera teres f. teres, barley scald disease caused by Rhynchosporium secalis, powdery mildew caused by Erysiphe graminis f. sp. hordei, barley brown (leaf) rust caused by Puccinia hordei and barley stripe disease caused by Drechslera graminea. A total of 42 barley fields were inspected. Drechslera teres f. teres, Drechslera teres f. maculata, Rhynchosporium secalis, Erysiphe graminis f. sp. hordei, Puccinia hordei and Drechslera graminea were observed in 23, 21, 19, 9, 15 and 11 fields, respectively. Spot form of net bloch was observed in all districts with the exception of Keban and Maden districts. Net form of net blotch was not observed in Arıcak, Sivrice and Maden districts. Scald was not observed in Ağın, Baskil and Sivrice districts. Powdery mildew was not observed in Palu, Arıcak and Sivrice districts. Brown (leaf) rust was not observed in Arıcak, Sivrice, Ağın and Maden districts. Barley stripe was not observed in Arıcak, Keban, Ağın, Sivrice and Maden districts. Spot form of net blotch and net form of net blotch were the most commonly encountered diseases. Scald followed these diseases. Disease incidence percentages of Drechslera teres f. maculata, Rhynchosporium secalis, Drechslera teres f. teres, Erysiphe graminis f. sp. hordei, Drechslera graminea and Puccinia hordei were ranged between 1-20, 1-20, 1-25, 1-30, 1-30 and 1-45, respectively. Disease severity values of scald caused by R. secalis was ranged between 3-7. Disease severity values of other diseases were ranged between 3-5. Control methods should be implemented regarding these diseases. Keywords : Elazığ, Barley, Hordeum vulgare, barley leaf diseases
