| 摘 要： | 应用50%吡蚜酮水分散粒剂防治水稻稻飞虱(Nilaparvata lugens)。结果表明,该药剂对稻飞虱具有良好的防治效果,施药量在180、240、300 g/hm2浓度下,药后3、7、14 d的防效为64.28%～86.35%,且持效期较长。试验期间未发现该药剂在供试剂量下对水稻产生药害,可在生产上推广应用。

| Abstract: | The plot test of pymetrozine 50% WDG against Nilaparvata lugens was investigated.The results showed that at the concentration of 180,240,300 g/hm2 the control efficacy of pymetrozine reached 64.28%~86.35% for 3,7 and 14 d after application.And there was no phyto-toxicity during the trial period.So it is worth taking further application. |
