旱地马铃薯晚疫病防治杀菌剂筛选研究

Research on the Screening and Study of Fungicides Agent for Potato Late Blight

为筛选防治马铃薯晚疫病有效的药剂,测定了7种杀菌剂对马铃薯晚疫病的防治效果。结果表明,7种杀菌剂对马铃薯晚疫病均有不同程度的防效,防治效果从高到低依次为:氰霜唑、烯酰唑嘧菌、丁子香酚、银法利、克露、百泰、苦参碱。供试的7种杀菌剂中,氰霜唑和烯酰唑嘧菌处理的防效和增产率均较高,建议可在生产上大面积推广使用。

In order to screen effective fungicides against potato late blight,the control effects of 7 Fungicides on potato late blight were determined. The result shows,The 7 fungicides had different effects on potato late blight,and the control effect was from high to low: Cyazofamid,Enoyl pyrazole azoxystrobin,DingZixiang phenol,Fluopicolide,curzate,bity,matrine. Among the 7 Fungicides tested,both the control effect and yield increase rate were higher than those of cyanide and pyrazole,suggesting that they could be widely used in production.
