摘　　要：叶枯病是近年在哈尔滨市糖槭上发生比较严重的病害,该病的病原菌为叶槭叶点霉(Phyllostictanegundinis Sacc.et Speg.)。试验通过在带药PDA平板上分别测试16种不同杀菌剂对糖槭叶枯病菌菌丝生长的抑制作用,筛选出能够很好防治糖槭叶枯病的杀菌剂。结果表明,供试的16种杀菌剂对糖槭叶枯病菌均有抑制效果,其中米酰胺乳油、多.锰锌可湿性粉剂、全络合态代森锰锌可湿性粉剂和锰锌.烯酰可湿性粉剂对糖槭叶枯病菌抑制作用最好,抑菌率可达100%。其次是氟硅唑.苯丙咪唑-44号悬浮剂和苯醚甲环唑颗粒剂。In recent years, sugar maples leaf blight becomes more serious in Harbin, and its pathogen is Phyllosticta negundinis. Sixteen fungicides were tested for efficacy against the leaf spot disease of sugar maples. The results showed that all the sixteen fungicides could significantly inhibit mycelial growth, while prochloraz, carbendazim .mancozeb, mancozeb and mancozeb-dimethomorph proved to be the most effective fungicides, with their inhibitory rates up to 100%, which followed by flusiazole-carbendazim and difenoconazole.
