摘  要:
[目的]筛选马铃薯晚疫病防治药剂。[方法]采用58%甲霜灵锰锌可湿性粉剂,70%安泰生WP,银法利687.5g/L悬浮剂3种药剂对马铃薯晚疫病进行防效试验。[结果]银法利对马铃薯晚疫病的防效优于58%甲霜灵锰锌可湿性粉剂,70%安泰生WP。挽回产量损失效果十分明显,均在69%以上,其中用70%安泰生WP防治2次、银法利687.5g/L悬浮剂防治3次效果最好。[结论]结果为探索防治马铃薯晚疫病的新办法,开发新的有效药剂,切实提高防病保产效果提供了科学依据。

摘  要:
[Objective]To screen out potato late blight (Phytophthora infestans) prevention fungicides. [Method]The three kinds of pesticides, respectively, 58% WP Metalaxyl MZ and 70% of the Antai Sheng WP and Silver Farley 687.5 g/L SC, were used to conduct the potato late blight control efficacy. [Result]The control efficacy of silver Farley on potato late disease was better than 58% WP metalaxyl MZ and 70% An Taisheng WP, and the recovery rate of yield loss reached 223.77%. [Conclusion]The results provided scientific references to the exploration of new method on potato late blight prevention, development of new effective fungicides, and improvement on effects of disease prevention and yield saving.
