大白菜根肿病化学防治技术

摘要

在大白菜的不同生育期,采用多种杀菌剂和不同的防治方法防治大白菜根肿病,试验结果表明:50%氟啶胺和10%氰霜唑能有效防治大白菜根肿病,其防治效果优于其他化学药剂.在播种前用10%氰霜唑悬浮剂2 000倍液浸种,再用50%氟啶胺悬浮剂300倍液对苗床土壤和大田土壤进行消毒处理,对大白菜根肿病的防治效果可达85.70%,比清水对照增产42.32%.%A combined process of chemical control of clubroot in Chinese cabbage at different growth stages was carried out. The test results showed that fluazinam and cyazofamid were effective pesticides for control of clubroot.Its control efficiency was better than other chemical pesticides.Soaking seeds with 10%cyazofamid SC and treating seedbed soils and field soils with 50%fluazinam SC before seeding and transplantation,raised the control efficiency to 85.70% and increased the yield by 42.32%.
