黄山稻区单季中稻防控褐飞虱大发生技术研究

摘要

为了明确单季中稻褐飞虱大发生条件下的防控技术。通过不同药剂组合进行防治褐飞虱的田间药效试验，并进行大田示范验证。结果表明，在四(2)代低龄若虫高峰期选择对褐飞虱高效的药剂呋虫胺进行防治，并在五(3)代低龄高峰期使用呋虫胺或吡蚜酮等再进行1次防治，可以有效控制褐飞虱危害。%In order to definite the control technology on brown planthopper in outbreak year, field efficacy trials and demonstration were carried out by combinating different pesticides. The results showed that brown planthopper could be controlled effectively when dinotefuran was used at peak stage of low instar nymphs of 4 (2) generation, then dinotefuran or pymetrozine was used at peak period of 5 (3) generation.
