本地前期一、二、三代灰飞虱主要传播以条纹叶枯病为主的病毒病,后期五、六代灰飞虱导致植株尤其是穗部煤污发黑。烯啶虫胺单用防治一代成虫、三代若虫效果较好。有效剂量相同的烯啶虫胺粒剂防效略优于液剂。烯啶虫胺在干旱无水的麦田使用,药效不能完全发挥,对灰飞虱的杀伤力不强。
The first one, two or three generations of Laodelphax striatellus mainly spread the stripe virus disease, the latter five or six generations of Laodelphax striatellus caused the plants, especially the spike of black coal. Nitenpyram alone control generation of adults, three generations of nymphs better. The same effective dose of nitenpyram granules prevention effect slightly better than liquid. Nitenpyram is used in arid and dry wheat fields, and its efficacy can not be fully exerted. Its lethality to Laodelphax striatellus is not strong.
