Abstract<\/strong><\/p>\n

This study aimed to conduct field survey of spot diseases of barley grown in zone1 and zone2 in the north eastern part of Syria in 2016 and 2017. Ten local varieties of barley were tested against tan spot (Helminthosporium tritici-repentis<\/em>) disease under laboratory conditions. The plants were infested in two stages, the first was in tillering and booting stages, while the second was only in booting stage. Results of field survey showed that barley was infected with spot diseases caused by Helminthosporium tritici-repentis, Helminthosporium sativum,<\/em> Alternaria alternate<\/em> and Rhynchosporium secalis<\/em>, the first species (H.tritici-repentis<\/em>) was the most commonly distributed with rates reached\u00a0 64.17% and 63.63% in 2016 and 2017, respectively. The distribution of the second species (H.sativum<\/em>) were\u00a0 25.37% and 24.54% respectively. The third species (A.alternata<\/em>) distribution were 5.97% and 4.54% respectively, while the fourth species (R. secalis<\/em>) distribution rates were 4.47% and 7.27% in 2016 and 2017 respectively. Results also showed that “Arabi Aswad” variety was the most sensitive cultivar, while the varieties “Furat 2”, “Furat 3” and “Furat 6” were the most resistant at tillering stage, whereas at booting stage “Furat 7” was the most sensitive cultivar, and “Furat 2” and “Furat 6” were the most resistant cultivars. Values of ratio and severity of infection were less when the plants infected in booting stage comparing to its values at the same stage when the plants were infected in both tillering and booting stages.<\/p>\n
