7种吡.单可湿性粉剂对稻飞虱、稻纵卷叶螟和三化螟的田间防治试验结果表明,施用吡.单可湿性粉剂14天后对稻飞虱的防治效果均保持在94%以上;对稻纵卷叶螟的防治效果为86.71%~91.60%;对三化螟的防治效果略差,但对水稻三化螟均具有一定的兼防作用。建议在生产上推广使用吡.单可湿性粉剂防治水稻害虫。
The results of field trials on the control of planthoppers, rice leaf roller and rice stem borer against seven species of single WP showed that the control effect on planthoppers was only 94% ; The control effect on Cnaphalocrocis medinalis was 86.71% ~ 91.60%; the control effect on Borer was worse than that on Bt rice, but it had a certain anti-control effect on Borer. Proposed in the promotion of the use of pyridine single WP to control rice pests.
