摘　　要：烯肟菌酯为甲氧基丙烯酸酯类杀菌剂,杀菌谱广,活性高,具有预防及治疗作用,与环境生物有良好的相容性,对由鞭毛菌、结合菌、子囊菌、担子菌及半知菌引起的多种植物病害有良好的防治效果。田间试验结果表明:对白菜霜霉病具有很好防治效果显著优于对照药剂72.2%霜霉威水剂、70%百菌清可湿性粉剂和25%甲霜灵可湿性粉剂,与25%嘧菌酯悬浮剂及69%安克·锰锌可湿性粉剂相当。处理剂量100～200ga.i./hm2,施药2～3次,对白菜霜霉病的防治效果能稳定在90%以上。Enestroburin is a highly active strobilurin fungicide with a broad spectrum of activity, providing both preventive and curative effects and minimal impact on environmental biology. Enestroburin controls Mastigomycetes, Zygomycetes, Ascomycetes, Basidiomycetes, and Deuteromycetes. Enestroburin provided good activity in field experiments against Chinese cabbage downy mildew. Efficacy was significantly better than that provided by propamocarb 72.2% AS, metalaxyl 25% WP, and chlorothalonil 70% WP, and was equivalent to that given by azoxystrobin 25% SC and dimethomorph plus mancozeb 69% WP. Enestroburin provided 90% control of Chinese cabbage downy mildew in the field when applied 2-3 times at 100-200 g a.i./ha.
