摘　　要：为明确45%烯肟菌胺·苯醚甲环唑·噻虫嗪悬浮种衣剂对小麦金针虫、蚜虫、纹枯病、白粉病、锈病等主要病虫害的田间防控效果及最佳用药量,以周麦27为试验品种、以30 g/L苯醚甲环唑FS＋20%烯肟·戊唑醇SC为对照药剂、设置3种不同药种质量比（40 g/10 kg、60 g/10 kg、80 g/10 kg）进行了田间试验。结果表明：经45%烯肟·苯醚·噻虫嗪FS包衣后对小麦发芽、出苗无不良影响,不产生药害,对主要病虫害双重兼治。其中包衣量80 g/10 kg比60 g/10 kg、40 g/10 kg的防治效果要好,除对叶锈病防效比对照药剂稍低外,对小麦主要病虫害的防控效果和增产作用总体比对照药剂好;80 g/10kg包衣量下对金针虫、蚜虫、纹枯病、白粉病、锈病的防效分别为80.76%~86.78%、44.10%~97.87%、80.56%~89.83%、85.23%、90.42%,比CK增产9.07%,相比对照药剂增产0.78%。To identify field prevention and control effect and optimal dose of 45% fenaminstrobin-difenoconazole-thi- amethoxam FSC on wheat wireworm, aphids, sheath blight, powdery mildew, rust and other major diseases and insect pests, field trials was conducted with wheat Zhoumai 27 as tested varieties and using 30 g/L difenoconazole FS＋20% diniconazole SC as contrast, three different kind of mass ratio （40 g/10 kg, 60 g/10 kg, 80 g/10 kg） were set. The results showed that after coating with 45% fenaminstrobin-difenoconazole-thiamethoxam FSC, which had no negative effects on wheat germination, emergence and other harmful effects, controlled major diseases and insect pests. The control effect with coating amount 80 g/lO kg was better than that of 60 g/10 kg, 40 g/10 kg. Except the control effect to leaf rust disease, which was lower than the contrast agents, the control effect to main diseases and insect pests and yield increase of wheat was better than the contrast agents in general. With 80 g/10 kg coating amount, the control effect to the wireworm, aphids, sheath blight, powdery mildew, rust was 80.76%- 86.78%, 44.10%- 97.87%, 80.56%- 89.83%, 85.23% and 90.42% respectively, yield increase was 9.07% than CK and 0.78% higher than that of the contrast agents.
