摘要:
油菜根肿病是一典型土传病害,防治困难。选用生产上常用的8种药剂,比较不同药剂使用剂量、施药方式和施用时间对油菜根肿病的防效。结果表明,不同施药方式药剂出苗率不同:药剂拌土整体出苗率较高,氰霜唑、氟啶胺、噻唑锌出苗率均高于70.00%;药剂浇淋,氰霜唑出苗率最高,达到96.67%;药剂拌种,整体出苗率偏低。药剂拌种、药剂浇淋和药剂拌土平均防效分别为81.55%、67.47%和62.44%。3叶1心期,药剂灌根,以氟啶胺、氰霜唑和多菌灵的防治效果较好,分别为71.9%、71.1%和70.2%。

Abstract:
Fungicides efficacy trials were carried out by choosing commonly used agents in the greenhouse and field, and the influence of different fungicides, application ways and control of time on rape clubroot disease and the rape growth were studied. The results showed that the different application ways could lead to different seedling emergence rate, and seedling emergence rate of rapeseeds was higher by means of agents with soil; seedling emergence rate was more than 70.00% by fluazinam and cyazofamid with soil;seedling emergence rate of rapeseeds was lower by means of agents with seeds; seedling emergence rate was 96.67% by watering roots with cyazofamid. The average control effect was 81.55%, 67.47% and 62.44% by agents with seeds,potions to douse the soil and agents with soil, respectively. The control effects were 71.9%, 71.1% and 70.2%, respectively by watering roots with fluazinam, cyazofamid and carbendazol at the stage of 3 leaves and 1 heart of rape.
Key words:  rape clubroot disease  fungicides  reagent application ways  control effect
