[目的和方法]通过室内联合毒力试验、田间药效试验明确烯酰吗啉与氟啶胺混剂对辣椒疫病的防治作用。[结果]室内联合毒力试验结果表明,烯酰吗啉与氟啶胺混配,在3∶1~1∶3配比范围内,对辣椒疫病表现出相加或略增效作用;田间于辣椒疫病初发期施药,40%烯酰吗啉·氟啶胺悬浮剂对辣椒疫病具有良好的防治效果。[结论]40%烯酰吗啉·氟啶胺悬浮剂可作为防治辣椒疫病的新品种,具有很好的开发前景。 [Objective] To investigate the preventive and curative effect of mixture of dimethomorph and fluazinam on pepper blight disease through field combined virulence test. [Result] The indoor combined virulence test showed that dimethomorph combined with fluazinam showed additive or slightly synergistic effect on pepper blight in the range of 3:1 to 1: 3. Phytophthora blight epidemic spraying pesticide application, 40% dimethomorph · fluridamide suspension has good control effect on pepper blight. [Conclusion] 40% dimethomorph fluazinil SC could be used as a new variety for controlling pepper blight and had good development prospect.
