摘　　要：[目的]探讨黄芩白粉病在河北承德的发生规律,并用不同肥料、不同药剂对黄芩白粉病进行处理。[方法]结合施肥、施药处理,田间实地观察记载黄芩白粉病的发生规律。[结果]黄芩白粉病主要为害叶片和果荚,病菌以菌丝体和闭囊壳在黄芩病残体上越冬,发病高峰期在8月上旬～9月中旬;多晴少雨有利此病发生发展。施用尿素有利于发病,施用磷酸二氢钾、复合肥可减轻发病;40%氟硅唑EC10000倍液防治黄芩白粉病效果最佳,防效达87.33%。[结论]为生产区有效地防治黄岑白粉病提供理论依据。[Objective] The aim was to explore the occurrence regularity of Scutellariae Powdery Mildew in Chengde City of Hebei Province,and the disease was treated with different fertilizers and different fungicides. [Method] The field observation method was adopted to record the occurrence regularity of Scutellariae Powdery Mildew,combined with application of fertilizers and fungicides. [Result] Scutellariae Powdery Mildew mainly damage leaves and pods,the pathogen overwinter by mycelium and cleistothecium in diseased residual plants of Scutellaria baicalensis Georgi,morbidity peak of the disease is during early August to mid-september;it in favour of the disease in conditions of more sunny days and less rainfall. [Conclusion] Applying urea could be beneficial to the disease,applying monopotassium phosphate and compound fertilizers could reduce incidence of the disease;40% Flusilazole EC（1∶10 000）had best effect to control the disease,which could reach 87.48%. The study will provide theoretical basis for effective prevention and control of Scutellariae Powdery Mildew.
