Abstract
In this study, fungal foliage and head diseases occuring in the barley growing areas of Eskişehir province were determined. In 13 districts of the province, except for Mihalgazi district that no barley growing area present, survey studies were carried out in 2012. During the survey studies that represent all parts of province, prevalence and intensity of fungal foliage and head diseases were determined. Samples representing the each district was collected. A total of 121 fields were examined. The fungal foliage diseases determined were net blotch (Drechslera teres), barley stripe (D. graminea), leaf rust (Puccinia hordei), stem rust (P. graminis f. sp. tritici), scald (Rhynchosporium secalis), powdery mildew (Erysiphe graminis f. sp. hordei). Smuts (Ustilago spp.) were determined as head diseases. Mean prevalences of these diseases were determined as D. teres % 25.50, D. graminea % 1.75, P. hordei % 5.93, P. graminis f. sp. tritici % 0.07, Rhynchosporium secalis % 22.07, Erysiphe graminis f. sp. hordei % 0.45 and Ustilago spp. % 0.02.
