[目的]氟吡菌胺是拜耳公司开发的一种新型吡啶酰胺类杀菌剂,对卵菌纲病原菌引起的病害如霜霉病和疫病等具有良好的防治效果。[方法]采用常规生测方法研究了氟吡菌胺对马铃薯晚疫病和黄瓜霜霉病的室内杀菌活性。[结果]氟吡菌胺对马铃薯晚疫病和黄瓜霜霉病具有优异的防治效果。其EC50值分别为0.02、2.99 mg/L,防治效果优于对照药剂嘧菌酯。
[Objective] Fluopicolide is a novel pyridine amide fungicide developed by Bayer, which has good control effects on diseases caused by Oomycetes pathogens such as downy mildew and epidemic diseases. [Method] The indoor bactericidal activity of fluopicolide against potato late blight and cucumber downy mildew was studied by routine bioassay method. [Result] Fluopicolide had excellent control effect on potato late blight and cucumber downy mildew. The EC50 values were 0.02 and 2.99 mg / L, respectively. The control effect was better than that of the control agent azoxystrobin.
