由Phoma arachidicola引起的花生网斑病是目前花生生产中重要叶部病害之一，发病面积广，危害严重。为筛选出对花生网斑病防治效果好的新型药剂，本试验测定了13种杀菌剂对花生网斑病菌的室内毒力、田间防效和对花生主要农艺性状及产量的影响。结果表明，室内毒力测定中，30%苯甲·丙环唑EC的毒力最强，EC50为1.9344mg/L；50%啶酰菌胺WG、30%醚菌·啶酰菌SC、50%多菌灵WP和10%苯醚甲环唑WG的EC50均小于6mg/L，抑菌效果较好。田间药效试验结果显示，30%苯甲·丙环唑 EC 100.00mg/L 倍液的防效最好，可达67.90%；其次为60%唑醚·代森联WG、50%啶酰菌胺WG，防效分别为64.93%和62.84%。30%苯甲·丙环唑EC较对照增产43.86%。综合室内毒力和田间药效试验结果，30%苯甲·丙环唑EC、50%啶酰菌胺WG、60%唑醚·代森联WG、30%醚菌·啶酰菌SC、10%苯醚甲环唑WG对花生网斑病的防治效果均较好，在田间发病不同时期，可以轮换使用以上药剂，以降低抗药性，达到有效控制病害的目的。

Nowadays,peanut web blotch caused by Phoma arachidicola is a serious leaf diseases,which is distributed widely in the production field of peanut. In order to evaluate the new fungicides on peanut web blotch disease,the indoor toxicity,field control effect agronomic traits and pod yield of 13 type of fungicides for pathogen-ic fungus of peanut web blotch were tested. The results indicated that EC50 value of propiconazole of 1. 934 4mg/L, was the most effective,and EC50 values of boscalid,kresoxim-methyl-boscalid,carbendazim and difenoconazole were less than 6 mg/L. In field test,100. 00mg/L propiconazole was the best and could control 67. 90% disease, and further increased the yield of 43. 86% compared to control,followed by pyraclostrobin-metiram,boscalid with controlling effect of 64. 93% and 62. 84% respectively. According to the indoor toxicity and field control tests, propiconazole,boscalid,pyraclostrobin-metiram,Kresoxim-methyl-boscalid and difenoconazole were effective in controlling peanut web blotch disease. These fungicides were used in rotation in different period of disease,to reduce the resistance and control field peanut web blotch disease effectively.
