摘要
为了筛选出防治小麦锈病的高效新药剂,开展了80%戊唑醇可湿性粉剂田间防效试验。结果表明,2次药后7 d,80%戊唑醇可湿性粉剂97.5 g/hm2、120.0 g/hm2剂量的防效分别为85.89%、88.32%;2次药后14 d,防效分别为84.14%、85.79%,其防治效果优于对照药剂。说明该药剂对小麦锈病具有较好防治效果,且药效持效性好,建议在小麦生产中推广使用。
In order to find a new efficient reagent on wheat rust control, we made an experiment on field-controlling with 80% tebueonazole wettable powder. The results showed that 7 days after 2 times treatment, the efficacy of 80% tebueonazole wettable powder under the dose of 97.5 g/hm^2 and 120 g/hm^2 were 85.89% and 88.32% respectively; 14 days after 2 times treatment, the efficacy of 80% tebuconazole wettable powder under the dose of 97.5 g/hm^2 and 120 g/hm^2 were 84.14% and 85.79% respectively. The efficacy of target reagent was better than that of control. It shows that this reagent has relatively good control effect and long-last persistence on wheat rust. It is suggested .to be widely spread and used in wheat production.
