Diseased barley plants (Hordeum vulgare), were noticed in the area of Kumanovo, Bitola, Probistip, Skopje apac1/60/1/cw and Kocani, at the beginning of March, 2006.Our investigations were carried out in the period from 2006 to 2009.The plants were highly diseased, probably in the stage of germination, dwarfed with necrotic leaves and with poorly developed root.A rotten root collar was noticed notice in some plants, which could be easily pulled out from the soil.
Plants infected in a later developing stage became yellow from the top of the leaf, and many brown-olive, oval shape lesions were noticed.Conidia of Bipolaris sorokiniana (Sacc.) Shoen., were isolated from symptomatic lesions.
Pseudothecia animed blue lotion topical spray with asci and ascospores from teleomorph Cochliobolus sativus, were found on the barley straw in the same field the previous year.
