摘　　要：[目的]评价2种种子处理悬浮剂不同剂量下对小麦蛴螬田间防效及最适药剂用量。[方法]选用2种种子处理悬浮剂于小麦播种期,对小麦种子进行药剂处理,隔夜晾干后播种。[结果]7%噻虫嗪·咯菌腈·吡唑醚菌酯种子处理悬浮剂有效成分含量105、140、175 g/100kg种子对小麦蛴螬防效较好,播种后保苗效果达77.03%~87.96%,防效达83.52%~89.41%。20%氯虫苯甲酰胺·嘧菌酯·噻虫胺种子处理悬浮剂有效成分含量60、80、100 g/100kg种子对小麦蛴螬防效较好,播种后保苗效果达79.49%~88.86%,防效达80.29%~92.48%。[结论]7%噻虫嗪·咯菌腈·吡唑醚菌酯种子处理悬浮剂推荐有效成分用量105~175 g/100kg种子,20%氯虫苯甲酰胺·嘧菌酯·噻虫胺种子处理悬浮剂推荐有效成分用量60~100 g/100kg种子。[Aims]This study aims to evaluate the field control effect of 2 suspension concentrates for seed treatment and to determine the optimum dosages.[Methods]Two suspension concentrates for seed treatment were selected to coat corn seeds at the planting stage,and the seeds were sown after drying overnight.[Results]Thiamethoxam·fludioxonil·pyraclostrobin 7%suspension concentrate for seed treatment at 105,140,175 g/100kg seed was effective.The seedling emergence rate was 77.03%-87.96%,and the control effect was 83.52%-89.41%.Chlorantraniliprole·azoxystrobin·clothianidin 20%suspension concentrate for seed treatment at 60,80,100 g/100kg seed was effective.The seedling emergence rate was 79.49%-88.86%,and the control effect was 80.29%-92.48%.[Conclusions]Thiamethoxam·fludioxonil·pyraclostrobin 7%suspension concentrate for seed treatment is recommended at 105-175 g/100kg seed.Chlorantraniliprole·azoxystrobin·clothianidin 20%suspension concentrate for seed treatment is recommended at 60-100 g/100kg seed.
