针对辽宁省玉米生产中病虫害防控措施少且田间作业实施较难的实际情况，于2014年在辽西地区，以玉米顶腐病、玉米螟和灰斑病为防治对象，对玉米播种期和喇叭口期2个时期进行药剂防治主要病虫害综合防控技术进行了初步探讨，取得理想的效果：播种时采用7.5%克百威·戊唑醇悬浮种衣剂包衣处理种子，可有效的防控玉米顶腐病，防效达到90.66%~100%；喇叭口期采用一次机械喷雾的方式进行药剂防治，玉米螟的防治效果达到87.28%，玉米灰斑病的发病级别和病情指数分别下降0.9~2.52和46.79%~56.24%，降低了病虫害对玉米产量的影响，挽回产量损失3.91%~10.09%。

Aim at the situation of default in comprehensive prevention and control technology of main diseases and insect pests,and difficulty in field operation in corn production of Liaoning province. Taking maize top rot,maize borer and gray leaf spot as the objects of prevention and treatment,We preliminarily researched the comprehensive prevention and control technology of these diseases with chemicals in sowing and whorl stage in the west of Liaoning province in 2014. The results showed that treating with 7. 5% Carbofuran and tebucon-azole floating suspeusion seed coating agent was the best way to control corn top rot,with 90. 66% ~ 100%control efficacy;the chemical prevention using machine spray in corn whorl stage was taken,the control effi-cacy of corn borer was up to 87. 28% ,the disease grade and disease index of gray leaf spot was down to 0. 9~ 2. 52 and 46. 79% ~ 56. 24% . These measures reduced the effects of diseases and insect pests on corn yield,and the loss of corn yield was reduced by 3. 91% ~ 10. 09% .
