银法利对马铃薯晚疫病的防治效果研究

Study on Control Effect of Fluopicolide against Potato Late Bright

[目的]研究银法利对马铃薯晚疫病的防治效果。[方法]采用68.75%银法利叶面喷施,并测定病情指数、病烂薯率及产量等指标。[结果]105ml/hm2银法利对马铃薯晚疫病防治效果显著,68.75%银法利与70.0%安泰生混合施用能显著降低马铃薯烂薯率,且增产增收效果显著。[结论]为银法利的大面积应用提供了依据。

[Objective] The research aimed to study the control effect of 68.75% fluopicolide against potato late bright. [Method] 68.75% fluopicolide was sprayed on potato leaves,and measured the indexes of disease index,disease or rot tuber rate and yield. [Result] The results showed that 68.75% fluopicolide of 105 ml/hm2 was effective on controlling potato late bright. When 68.75% fluopicolide and 70.0% antaisheng were applied mixture,potato disease or rot tuber decreased significantly and yield and profit increased remarkably. [Conclusion] The study can lay the basis for application of fluopicolide in a scale.
