三化螟是湖北省水稻生产最大的害虫之一,近几年来,为害相当严重,特别是双季稻区的双季晚稻受害更凶,严重影响水稻生产。所以,消灭三化螟的为害成为当前水稻增产的重要环节之一。我省防治水稻螟虫目前主要依靠药剂防治。各地实践证明,药剂治螟,虽能在短期内压低螟害,对保护水稻增产具有很大作用,但不能全靠这个方法。
Borer borer is one of the largest pests of rice production in Hubei Province. In recent years, the damage has been quite serious. Especially, the double-season late rice in the double-cropping rice region harms more severely and seriously affects the rice production. Therefore, the elimination of the yellow rice borer damage has become an important part of the current rice yield. Prevention and control of rice stem borers in our province mainly rely on chemical control. Practices in various places have proved that although the chemical treatment of rice stem borer can suppress the damage of rice stem borers in a short time, it has a great effect on the protection of rice yield, but it can not rely on this method.
