Since barley stripe disease caused by Helminthosporium gramineum appeared as one of the most important diseases in East Azarbaijan and some other provinces, the biology of the pathogen was studied and the effectiveness of 4 fungicides to control the disease was also studied during 1990-92. The results showed that Rovral-TS and Imazalil of 255g commercial form, 100Kg seeds were the most effective ones. Mancozeb at 125g, and Imazalil at the 17ml of commercial forms were the second group, and Benlate-T at 100g of commercial form was the third.
