摘  要：
2011-2012年开展了氰霜唑、百菌清和氟啶胺防治油菜根肿病技术研究。试验结果表明:育苗前2～3d用氰霜唑0.5mL/L喷浇苗床对油菜苗根肿病的防治效果在90%左右。苗床消毒结合百菌清0.5g/L液灌根对移栽油菜田根肿病的防治效果67.6%～80.8%;单用苗床消毒措施的移栽油菜田根肿病防治效果57.1%～74.3%。氟啶胺和氰霜唑拌种对直播油菜根肿病的防病效果分别为75.4%～95.3%和35.1%～49.8%。苗床用氰霜唑消毒结合百菌清灌根和单用苗床消毒防病措施比不防治对照油菜分别增产949.0kg/hm2和799.1 kg/hm2,扣除农药和劳动力成本,分别增加收入2 935.8元/hm2和2 922.2元/hm2。

摘  要：
To improve the control techniques of rapeseed clubroot(caused by Plasmodiophora brassicae),the controlling effects of three fungicides were investigated during 2011-2012 under nursery bed and fields conditions respectively.Results showed that control efficiency was up to 90% by nursery bed disinfection with 0.5mL/L dilution of cyazofamid 2 to 3d before sowing.The disease occurence of plants from cyazofamid disinfection combination with or without roots irrigation using chlorothalonil decreased 67.6% to 80.8% and 57.1% to 74.3% respectively,compared with non-treatment plants.The disease occurence of plants from seed treatment with fluazinam or cyazofamid decreased 75.4% to 95.3%,and 35.1% to 49.8% respectively,compared with plants from non-treatment seeds.The yield of plants from cyazofamid disinfection combination with or without roots irrigation by chlorothalonil increased 949.0kg/hm2 and 799.1kg/hm2,and the income increased 2 935.8 yuan/hm2 and 2 922.2yuan/hm2 compared with non-control plants respectively.
