Diseased barley plants (Hordeum vulgare) were noticed in the area ofKumanovo at the beginning of March, 2008. The plants were highly diseased,probably in the stage of germination, dwarfed with necrotic leafs and very lowdeveloped root. We noticed a rot root collar in some plants and we were ableto dig them out of the soil very easily. Plants diseased in a later stage begin tobecome yellow from the top of the leaf and many brown to olivaceous ovalshape lesions were noticed. Conidia from Cochliobolus sativus (Ito. i Kurib)Drechsler ex Dastur. sin. Bipolaris sorokinianа (Sacc.) Shoen. were isolatedfrom symptomatic lesions. Pseudothecia with ascuses and ascospores fromtelemorfi c stage Helminthosporium sativum Pammel; King & Bakke werefound on the wheat straw from the previous year, in the same fi eld.
