摘　　要：应用600g/L吡虫啉FSC、44%吡虫·氟虫腈FSC、300g/L氯氰菊酯FSC、60%戊唑醇FSC、4.23%甲霜·种菌唑ME 5种药剂不同配方包衣‘先玉335’和‘金庆’2个玉米品种种子,验证各药剂对当地玉米出苗的安全性、对玉米苗期生长的影响及对玉米丝黑穗病和玉米蚜虫的防治效果。结果表明,玉米种子包衣后对出苗安全,且有很好的保苗、壮苗、增产作用,增产率最高可达19.6%。吡虫啉400、500、600、800mL+戊唑醇150mL+甲霜·种菌唑100mL组合以及吡虫·氟虫腈240、480mL+戊唑醇150mL+甲霜·种菌唑100mL组合对丝黑穗病防效均可达84%以上。吡虫啉800mL+戊唑醇150mL+甲霜·种菌唑100mL组合以及吡虫·氟虫腈240、480mL+戊唑醇150mL+甲霜·种菌唑100mL组合对‘先玉335’玉米上的蚜虫具有很好的防治效果,防效可达81.6%以上。吡虫啉500、600mL+戊唑醇150mL+甲霜·种菌唑100mL组合以及吡虫·氟虫腈480mL+戊唑醇150mL+甲霜·种菌唑100mL组合对‘金庆’玉米上的蚜虫防治效果较为突出,防效可达81.1%以上。In 2013,600 g/L imidacloprid FSC,44% imidacloprid·fipronil FSC,300 g/L cypermethrin FSC,60%tebuconazole FSC,4.23% metalaxyl·ipconazole ME were used as seed coating agents to treat the seeds of two maize varieties,‘Xianyu 335＇and ‘Jinqing＇,to verify the safety to maize seedling,the influence on plant growth,and the control efficacy against maize head smut and aphids.The results showed that all the treatments were safe to maize seedling,promoted the seedling growth and increased the yield by 19.6%.The control efficacies of both the combination of imidacloprid（400,500,600,800 mL）with tebuconazole（150 mL）and metalaxyl·ipconazole（100 mL）,and the combinations of imidacloprid·fipronil（240,480 mL）with tebuconazole（150 mL）and metalaxyl·ipconazole（100 mL）were over 84% against maize head smut.The control efficacies of both the combinations of imidacloprid（800 mL）with tebuconazole（150 mL）and metalaxyl·ipconazole（100 mL）,and the combinations of imidacloprid·fipronil（240,480 mL）with tebuconazole（150 mL）and metalaxyl·ipconazole（100 mL）were over 81.6% against corn aphids on‘Xianyu 335＇.The control efficacies of both the combination of imidacloprid（500,600 mL）with tebuconazole（150 mL）and metalaxyl·ipconazole（100 mL）,and the combination of imidacloprid·fipronil（480 mL）with tebuconazole（150 mL）and metalaxyl·ipconazole（100 mL）wereover 81.1% against corn aphids on‘Jinqing＇.
