论述了平榛白粉病的发病规律，利用不同浓度的代森铵、多菌灵、甲基托布津、三唑酮和百菌清药剂对平榛白粉病进行防治试验，比较了不同种类和不同浓度的药剂对平榛白粉病的防治效果。结果表明：平榛白粉病初期发病为5月下旬至6月初，发病高峰期为6月下旬至7月下旬；代森铵、甲基托布津、多菌灵、百菌清、三唑酮等药剂对平榛白粉病的防治均有不同程度的效果，以25%三唑酮可湿性粉剂防治效果最好，可达到80%以上。
論述瞭平榛白粉病的髮病規律，利用不同濃度的代森銨、多菌靈、甲基託佈津、三唑酮和百菌清藥劑對平榛白粉病進行防治試驗，比較瞭不同種類和不同濃度的藥劑對平榛白粉病的防治效果。結果錶明：平榛白粉病初期髮病為5月下旬至6月初，髮病高峰期為6月下旬至7月下旬；代森銨、甲基託佈津、多菌靈、百菌清、三唑酮等藥劑對平榛白粉病的防治均有不同程度的效果，以25%三唑酮可濕性粉劑防治效果最好，可達到80%以上。

The pathogenesis regularity on powdery mildew of Corylus heterophylla was discussed.Different concen-trations of dyson ammonium,carbendazim,thiophanate-methyl,triadimefon and chlorothalonil pesticides were used to control of powdery mildew C.heterophylla.Control effects of different types and concentrations on powdery mil-dew of C.heterophylla were compared.Result shows that early stage of powdery mildew of C.heterophylla is from late May to early June,the peak incidence is in late June to late July;dyson ammonium,thiophanate-methyl, carbendazim,chlorothalonil and triadimefon have effects with varying degrees;25% triadimefon WP can obtain the optimal control effect,being above 80%.
