亚麻枯萎病拌种杀菌药剂的筛选

Screening on Seed Dressing Bactericide of Flax Wilt

土壤和种子带菌是亚麻枯萎病发生的重要原因,通过抑菌试验和盆栽试验对10种杀菌药剂进行了筛选,抑菌试验表明克枯星、甲基托布津、治本、赛世抑菌效果较好,抑菌率均达到90%;盆栽试验表明克枯星,甲基托布津防治效果较好,枯死率可控制在5.0%以下,有效地降低了亚麻枯萎病的发病率,防治效果理想。

The soil and seeds with bacteria are the main factors for occurring of flax wilt.The ten kinds of bactericide were screened by inhibition test and pot experiment.Inhibition test showed that Kekuxing,Jiajituobujin,Zhiben and Saishi had significant inhibiting effect that their bacteriostasis rate were more than 90%.Pot experiment showed that Kekuxing and Jiajituobujin had better control effect,the wilt flax incidence could be controlled below 5.0%.They effectively reduced the incidence of flax wilt,moreover they had ideal control effect.
