Leaf Diseases of Wild Barley (Hordeum spontaneum) in Bingöl University Campus, Turkey

In May 2022, a survey was accomplished in the campus area of ​​Bingöl University, Turkey, and diseases in wild barley (Hordeum spontaneum) populations were determined. A total of 15 H. spontaneum populations were examined. In these populations, powdery mildew incited by Blumeria graminis f. sp. hordei, scald incited by Rhynchosporium commune, the net form of net blotch incited by Pyrenophora teres f. teres, and spot form of net blotch incited by Pyrenophora teres f. maculata were determined by visual identification. Powdery mildew was observed in all 15 populations. Scald, the net form of net blotch, and spot form of net blotch were observed in 7, 3, and 2 populations, respectively. In these areas, the percentages of these diseases varied between 50–90% for powdery mildew, 10–30% for scald, 2–3% for the net form of net blotch, and 1–2% for the spot form of net blotch. Scale values for disease severity were higher in powdery mildew (between 5–9), 3–5 for scald, and low in both forms of net blotch (1–3, and 1–2).
