摘　　要：[目的]评价10%吡虫啉·高氟氯·咯菌腈种子处理悬浮剂、10%噻虫胺·咯菌腈·苯醚甲环唑种子处理悬浮剂、11%丙硫菌唑·咯菌腈·噻虫胺种子处理悬浮剂3种药剂对小麦沟金针虫的田间防效。[方法]3种种子处理悬浮剂于小麦播种期进行种子包衣处理,第2年小麦沟金针虫盛发期调查。[结果]10%吡虫啉·高氟氯·咯菌腈种子处理悬浮剂有效成分含量120、140、160 g/100kg种子对小麦沟金针虫防效较好,播种后保苗效果达75.20%~85.13%,防效达80.47%~87.85%;10%噻虫胺·咯菌腈·苯醚甲环唑种子处理悬浮剂有效成分含量105、130 g/100kg种子对小麦沟金针虫可达防治要求,播种后保苗效果达79.82%~86.13%,防效达81.08%~90.42%;11%丙硫菌唑·咯菌腈·噻虫胺种子处理悬浮剂有效成分含量132、198 g/100kg种子对小麦沟金针虫播种后保苗效果达82.63%~87.14%,防效达84.80%~88.81%。[结论]3种种子处理悬浮剂均可达小麦沟金针虫防治要求,生产中可交替使用。[Aims]This study aims to evaluate the field control effect of imidacloprid·beta-cyfluthrin·fludioxonil 10%suspension concentrate for seed treatment(FS),clothianidin·fludioxonil·difenoconazole 10%FS and prothioconazole·fludioxonil·clothianidin 11%FS on Pleonomus canaliculatus.[Methods]We coated wheat seeds with the selected three suspension concentrates for seed treatment at the planting stage,and investigated the control effect on the peak occurrence period of P.canaliculatus in the second year.[Results]Imidacloprid·beta-cyfluthrin·fludioxonil 10%FS at 120,140,160 g a.i./100kg seed was very effective,with the seedling emergence rate of 75.20%-85.13%,and the control effect of 80.47%-87.85%.Clothianidin·fludioxonil·difenoconazole 10%FS at 105,130 g a.i./100kg seed was effective,with the seedling emergence rate of 79.82%-86.13%,and the control effect of 81.08%-90.42%.Prothioconazole·fludioxonil·clothianidin 11%FS at 132,198 g a.i./100kg seed was effective,and the seedling emergence rate was 82.63%-87.14%,and the control effect was 84.80%-88.81%.[Conclusions]The three suspension concentrates for seed treatment have good field control effect on P.canaliculatus,and can be used alternately in production.
