Abstract :

In order to evaluation of conventional fungicides effect on barley strip disease controlling, infected barley seeds of PropStar variety were collected from Achachy region barley fields located in Miyaneh, Iran and their infection percentage has been determined about 72% by culture plate test method. An experiment was conducted in greenhouse conditions for evaluation of 0.5, 1 and 2 % of Carboxin 75WP, Carboxin-tiram 75WP, Tilt 250EC, Carbendazim 60WP, Rovral-TS 52.5WP, Benomyl 50WP, Diniconazole 2WP, Difenoconazol 3DS, Maneb 80WP and Mancozeb 80WP on seed viability, as completely randomized design with 4 replications. The results revealed that all treatments didn’t have significant difference with control rather than Tilt and 2% of Carboxin-tiram. Another experiment was conducted as randomized complete block design with 3 replications in field condition. After seed treatments with recommended doses of above fungicides, 100 seeds was sown in a 10 m rows with 1 cm intervals in each plot. Plant infection percentages were calculated and analysis of variance and mean comporisons with Duncan’s multiple range test in 5% probability showed that Benomyl and Carbendazim had no effect on disease controlling. Also, other fungicides had significant difference with control and all of them can be recommended for field applications. However the most effective fungicides were Rovral-TS and Mancozeb and Maneb and Difeniconazole had the least effect on the disease, statistically.
