During operating this propozal the fields of barley in different provinces were survived .Samples of plants which had disease symptom were collected and examined for infection.The results are as follows: In Markazi province these fungi Fusariumspp,Gaeumannomyces graminis var tritici ,Drechslera sorokiniana,Embllisia chlamidospora,Rhizoctonia solani were identified as acausual agents of root and crown rot of barley.In Hamedan Fusarium spp Gaeumannomyces graminis var tritici Rhizoctonia spp Pythium spp Bipolaris spp Drechslera spp ,in Zanjan Rhizoctonia solani' Fusarium culmorum and 9 species of Fusarium sp were identified.Only the pathogenecity of Rhizoctonia solani is tested.In Kermanshah province the fungi Bipolaris sorokiniana , B. cynodontis. Rizoctonia cerealis , R. solani , Pythium ultimum ,Phoma glomerata , Fusarium oxysporum , F. nygamai , F. culmurum , Fusarium solani , F. avenaceum, F. compactum , F. equiseti were identified and in Mazandaran Fusarium graminearu was more than the others.All the inoculated fungi except Alternaria' Pythium' F. oxysporum and Cladosporium were pathogenic. Fusarium graminearum was the most frequent one.In Yazd ,Rhizoctonia solsni, Pythium sp , F.culmorum , Fusarium graminearum and Fusarium spp were isolated as the pathogenic fungi of root and crown rot of barley.In Tehran province these fungi Helminthosporium sativum , Fusarium culmorum , F. scirpe , F.equiseti , F. acuminatum , Rhizoctonia solani were identified as casual agent of root and crown rot of barley.
