摘　　要：为研究探索玉米生育中后期病虫害前期综合防控的适宜方法,于2016年在辽宁不同玉米产区,以玉米螟和玉米灰斑病、大斑病为防治对象,采用大区试验的方法,在喇叭口期提前施用药剂,对玉米生育中后期主要病虫害进行药剂防控。结果表明,玉米螟的防控效果达到74.66%,玉米灰斑病和大斑病的防控效果达到51.28%~70.67%,有效降低了病虫害对玉米产量的影响。In order to study and explore the proper method for early period comprehensive prevention and control against diseases and insect pests in the late stage of maize growth, in 2016, using the maize corn borer, maize gray leaf spot and northern leaf blight as the prevention and control objects, by wide field experiment method, we made the prevention and control in the late stage of maize growth by spaying pesticide in advance at trumpet period in different product area in Liaoning Province. The results showed that the control efficacy of corn borer was 74.66%, the control efficacy of maize gray leaf spot and northern leaf blight was 51.28% ~70.67%. The technology effectively decreases the negative influence on maize production by diseases and pests.
