8种药剂防治大白菜根肿病田间药效试验比较

摘要

在陕西太白县进行8种药剂防治大白菜根肿病的田间防效试验。试验结果表明，福帅得（氟啶胺）悬浮剂防治大白菜根肿病的防效最高，为89.92％，其次是BJYT悬浮剂和科佳（氰霜唑）悬浮剂，防效分别是88.78％和86.84％。这3种药剂为本次试验中防治大白菜根肿病效果较好的药剂，可以在生产中推广应用。%We carried out the experiment to compare the control effects of eight fungicides against Chinese cabbage clubroot in Taibai county of Shaanxi. The results showed that, the funicide Frowncide (fluazinam) suspension concentrate (SC) had the highest control efficiency of 88.92%against Chinese cabbage clubrooot, followed by the two fungicides BJYT SC and Segway (cyazofamid) SC, and their control efficiencies were 88.78% and 86.84% respectively. In our research, these three fungicides had better control effect against Chinese cabbage clubroot, so they could be widely used in production.
