摘　　要：[目的]明确吡唑醚菌酯和苯醚甲环唑混合对花生褐斑病毒力增效作用。[方法]室内联合毒力测定和田间药效试验。[结果]筛选得到吡唑醚菌酯与苯醚甲环唑的增效型混剂。[结论]吡唑醚菌酯与苯醚甲环唑以1:1混配对抑制菌丝生长增效最为明显,共毒系数为138.86。田间药效试验中,20%吡唑醚菌酯·苯醚甲环唑悬浮剂对花生叶斑病的防治效果达到84.50%,显著优于2个单剂的防效。[Aims] The paper aims to confirm the synergistic effect of pyraclostrobin and difenoconazole against Cercospora arachidicola on peanut. [Methods] Joint toxicity measurement and field trial method were used. [Results] A synergistic mixture containing pyraclostrobin and difenconazole was obtained. [Conclusions] The synergistic effect of the mixture with the ratio of 1：1 was the the most obvious with coefficient of 138.86. Field trial results showed that the control efficacy of the mixture against peanut leaf spot disease was 84.50%, which was higher than these two pesticides.
