摘　　要：草地贪夜蛾自入侵我国以来,发生范围越来越广,为害越来越重,目前国内虽有大量防控草地贪夜蛾药剂试验的报道,但鲜有拌种剂与茎叶喷雾组合防控草地贪夜蛾的研究。为此,于2022年开展了50%氯虫苯甲酰胺拌种与25%乙基多杀菌素茎叶喷雾组合、50%氯虫苯甲酰胺拌种与5.7%甲维盐茎叶喷雾组合、25%乙基多杀菌素茎叶喷雾、5.7%甲维盐茎叶喷雾4种处理对玉米的安全性、田间防治效果及增产效果试验。结果表明,氯虫苯甲酰胺拌种+乙基多杀菌素茎叶喷雾组合保苗、控虫、增产效果显著。药剂拌种处理后玉米出苗率显著高于空白对照,拌种剂对玉米有促进出苗的作用;在草地贪夜蛾大量发生的情况下,使用50%氯虫苯甲酰胺拌种可有效控制草地贪夜蛾对玉米生长前期的危害,但玉米中后期仍需依靠乙基多杀菌素等高效药剂进行茎叶喷雾才能控制草地贪夜蛾的危害。各药剂处理对玉米的增产作用显著,其趋势是50%氯虫苯甲酰胺拌种与25%乙基多杀菌素茎叶喷雾组合>50%氯虫苯甲酰胺拌种与5.7%甲维盐茎叶喷雾组合>25%乙基多杀菌素茎叶喷雾>5.7%甲维盐茎叶喷雾。Since the invasion of Spodoptera frugiperda into China,its occurrence has become more and more extensive,and its harm has become more and more serious.Although there are a lot of reports on the control of Spodoptera frugiperda in China,there are few studies on the control of Spodoptera frugiperda by the combination of seed dressing agent and stem leaf spray.For this reason,in 2022,the author carried out the safety,field control effect and yield increase effect tests of four treatments on maize,namely,50%chlormebenzamide seed dressing and 25%spinetoram stem and leaf spray,50%chlormebenzamide seed dressing and 5.7%emamectin benzoate stem and leaf spray,25%spinetoram stem and leaf spray,and 5.7%emamectin benzoate stem and leaf spray.The results showed that the combination of chloramphenicol seed dressing+spinetoram stem and leaf spray had significant effects on seedling protection,insect control and yield increase.The emergence rate of maize after chemical seed mixing treatment was significantly higher than that of the blank control,and the seed mixing agent had a promoting effect on the emergence of maize;In the case of a large number of Spodoptera frugiperda,seed dressing with 50%chloramphetamine can effectively control the damage of Spodoptera frugiperda to maize in the early growth stage,but in the middle and late growth stage of maize,it still needs to rely on efficient agents such as spinetoram for stem and leaf spray to control the damage of Spodoptera frugiperda.Each chemical treatment has a significant effect on the yield increase of maize,and its trend is that the combination of 50%chloramphenicol seed dressing and 25%spinetoram stem and leaf spray>the combination of 50%chloramphenicol seed dressing and 5.7%emamectin benzoate stem and leaf spray>the combination of 25%spinetoram stem and leaf spray>5.7%emamectin benzoate stem and leaf spray.
