| 摘 要： | 对山东荷泽牡丹在湖南长沙地区种植时病害进行了病原物分离鉴定,确定其主要病害有牡丹灰霉病、牡丹褐斑病、牡丹红斑病、牡丹枝枯病和牡丹根腐病。并对主要病害的发生发展规律进行系统调查,发现病害的发病高峰期为6—8月,随降雨量的增加,田间相对湿度变大,病情加重。通过室内药剂筛选试验,表明75%代森锰锌可湿性粉剂对5种病原菌都有很好的抑制作用,25%咪鲜胺乳油对牡丹灰霉病菌、牡丹褐斑病菌、牡丹红斑病菌和牡丹根腐病菌有较好抑制作用,对牡丹枝枯病菌基本上没有抑制作用。

| Abstract: | We studied the peony disease which planted in the Hunan Changsha, and found that the main diseases of peony in Hunan were peony grey mildew, Peony brown spot, Peony red spot disease, Peony branch-rot disease and peony root-rot disease. We found that there was a peak between June and August with rainfall amount increase through system investigation.
