为筛选高效、安全的黄瓜霜霉病防治药剂,通过田间试验评估了双炔酰菌胺、苯甲·氟酰胺、苯菌酮等新型杀菌剂的防治效果。结果表明,供试药剂处理对黄瓜霜霉病均有较好的防效,以23.4%双炔酰菌胺悬浮剂的防效最佳,其不同浓度处理在药后14d防效均达89%以上,12%苯甲·氟酰胺悬浮剂次之。总体上,同一药剂不同浓度处理以高浓度处理防效更优,但差异不显著。试验期间未见药剂处理对作物生长产生不良影响。
In order to screen efficient and safe cucumber downy mildew control agents, the control efficacy of novel fungicides such as mandipropamid, benzofluoran, and phenbendazole were evaluated in field experiments. The results showed that the control agent had a good control effect on cucumber downy mildew, 23.4% mandrel dominate the best control effect of different concentrations of 14 days after treatment in the control effect was up to 89% Above, 12% benzofenamide suspension followed. In general, the same agent treated with different concentrations of high concentrations of better control effect, but the difference was not significant. No treatment during the test had adverse effects on crop growth.
