摘  要:
为探索葡萄霜霉病的发病规律及可以替代波尔多液的防治葡萄霜霉病的有机药剂;而在京郊有机葡萄园葡萄霜霉病发生规律的调查及药剂防治试验。结果表明:葡萄霜霉病的发病始期为6月上中旬,7月下旬至8月初进入发病高峰期,9月上中旬随着湿度的下降而减弱;多种药剂的筛选试验证实:同波尔多液相比,在6月下旬喷施植物油乳化剂对葡萄霜霉病的防治效果与波尔多液的效果差异不显著。因此植物油乳化剂可以在发病初期替代波尔多液。

摘  要:
The occurrence of Plasmopara viticola was investigated at Qianlong organic commercial vineyard,in Yanqing couty ,Beijing on 2006. In order to reduce the use of copper-contained pesticides,the control effects of organic pesticides on it were researched. Our data shows that mildew emerge on early June,prevail on August,and the incidence was declined accompanying with the increasing the number of sunny days on September. Thus late June is crucial to the control of mildew. According to our findings,the control effect between oil and Bordeaux on downy mildew has no significant difference,in late June. This study suggests that oil can replace Bordeax mixture on early period of Plasmopara viticola’s intrusion.
