摘　　要：葡萄霜霉病是葡萄栽培主要病害之一,选用20%丁子香酚等5种药剂开展葡萄霜霉病防治试验。结果表明,5种药剂的葡萄霜霉病防治效果均优于对照,两处试验点丁子香酚、氟菌、霜霉威和稀酰·唑嘧菌防效均优于噁酮·锰锌、噁酮·霜脲氰;丁子香酚、氟菌·霜霉威和稀酰·唑嘧菌在鲜食葡萄基地的防效高于酿酒葡萄基地;天水地区7月上旬20%丁子香酚每隔10 d连喷3次,其防效达到80.34%,可作为防治葡萄霜霉病的优选生物药剂推广使用。Plasmopara viticola is one of the main diseases of viticulture,and 5 agents such as 20%butyl fragrant phenol are selected to carry out the control test of grape downy mildew.The results showed that the control effects of the five agents were better than those of the control group,and the control effects of butylvanol,Fluorobacterium downy mildew and chloryl azoxystole were better than oxone manganese zinc,oxone frost urea cyanogen in the two experimental sites;The control effect of butylvanol,flurobacter downy mildew and acyl azoxystole in table grape base was higher than that in wine grape base.In Tianshui area,20%butathiol was sprayed three times every 10 days in early July,and the control effect reached 80.34%,which could be used as the preferred biological agent for the control of Plasmopara viticola.
