摘　　要：研究以常规喷雾用和种子处理用2种剂型多种药剂进行桶混拌种为核心,大田采用生物源药剂,配合必要化学药剂的水稻病虫全程绿色用药技术。2019、2020年试验结果表明,复方药剂拌种对纹枯病防效优异,且水平扩展盛期推迟20 d左右。对稻瘟病控制时间长、效果好。对纵卷叶螟防效优异,五(3)代防效为98.25%,第4代仍达83.86%。螟虫防效较好,对二化螟第二代保穗效果仍达20%左右。由于其防效高、持效期长,大田可使用生物农药为主,减轻了中后期化学用药压力。In this study,2 kinds of pesticide mixtures were used as core of conventional spray and seed treatment,and the green technology of rice pests and diseases was applied in the field with biogenic chemicals and necessary chemicals.The test results in 2019 and 2020 showed that seed dressing with compound agent had good control effect on sheath blight,and the peak period of horizontal expansion was delayed by about 20 days.The control time of rice blast was long and the effect was high.The control effect on leaf roller was good.The leaf protection effect of five(3)generations was 98.25%,and that of the fourth generation was still 83.86%.The control effect of stem borer was good,and the effect of ear preservation on the second generation of Chilo suppressalis was still about 20%.Because of its high control effect and long duration,biological pesticides could be mainly used in the field,which reduced the pressure of chemical drugs in the middle and later stage.
