2012~2014年,河北省农林科学院植物保护研究所对葡萄霜霉菌对新型仿生杀菌剂缬霉威的抗性风险评估进行了研究,并于近期公布了研究结果。研究人员采集尚未使用过缬霉威的105个葡萄霜霉菌株,建立了其对缬霉威的敏感基线。葡萄霜霉菌对缬霉威的有效抑制中浓度EC_(50)为 From 2012 to 2014, the Institute of Plant Protection of Hebei Academy of Agricultural and Forestry Sciences conducted a study on the risk assessment of resistance of grape downy mildew to the new biomimetic fungicide, and recently published the research results. The researchers collected 105 grape downy mildew strains that had not been used before, and established a sensitive baseline for the tripterygium. The effective inhibitory rate of grape downy mildew on the mold was 70%
