超级杂交中稻主要病虫药剂防治新技术研究

2004～2005年，在稻曲病防治新药剂筛选及药剂防治适期研究的基础上，针对超级杂交中稻纹枯病、稻曲病、稻飞虱和螟虫等主要病虫发生量大及危害严重的特点，开展了药剂防治试验．形成了一套适合超级杂交中稻主要病虫药剂防治的专用技术。该技术对超级杂交中稻主要病害防效达80％左右，对虫害防效达90％以上。与常规病虫防治技术相比，该技术成本相当，增产增效非常明显，同时可减少对环境及稻谷的污染，实现超级杂交中稻无公害生产的目的。

Study on New Techniques for Pesticide Prevention to Main Diseases and Insect Pests in Medium Super Hybrid Rice

Aimed at the status of severe occurrence and damage of main diseases and insect pests in medium super hybrid rice, such as rice sheath blight disease, rice false smut, rice plant hopper and paddy rice borer, and so on, the reagent prevention and control experiments were conducted in 2004-2005 at the basis of studies on new fungicide screening and preventing period of rice false smut, and a new special technique had been established. The controlled effect of this technique to main diseases of super hybrid rice was about 80%, and the controlled effect to insect pests was above 90~. The application cost of the new special technique was equivalent to the normal technique, but the new one heightened yield and benefit significantly and decreased the pollution to rice and environment, and achieved the antipollution production of medium super hybrid rice consequently.
