戊唑醇和三唑酮拌种防治大麦条纹病研究

Control effect of seed dressing with raxil and bayleton on stripe disease of barley

分别选用3种不同浓度的6%戊唑醇FS和15%三唑酮WP对‘云大麦2号’进行拌种,研究其对大麦条纹病的防治效果。结果表明：6%戊唑醇FS处理大麦种子对条纹病具有很好的防效,每kg种子用药0.25~0.5 mL防效好,并对大麦发芽、成苗和苗期生长无影响;15%三唑酮WP处理大麦种子对大麦条纹病具有一定防效,但对大麦发芽、成苗和苗期生长有一定抑制作用,生产上应慎用。

Control effect of seed dressing with 6% raxil FS and 15% bayleton WP on stripe disease of barley cv.Yundamai No.2 were investigated with three different concentrations,the results showed as follows： The treatment of seed dressing with 6% raxil FS showed good preventive effect on barley stripe at the concentration of 0.25-0.5 mL per kilogram seeds,meanwhile,there was no effect on germination and seedling growth.The treatment of seed dressing with 15% bayleton WP also showed good preventive effect on barley stripe,but it showed certain inhibitory effect on germination and seedling growth,so it should be carefully utilized in production.
