摘要
对25%吡蚜酮悬浮剂(24 mL/667 m2)与常规对照药剂10%吡虫啉可湿性粉剂(25 g/667 m2)防治早稻稻飞虱进行药效试验,评价25%吡蚜酮悬浮剂对稻飞虱的防治效果。结果表明:25%吡蚜酮悬浮剂对稻飞虱有较好的防效,可提高水稻产量,减少施药用工,增加经济效益。
Efficacy testing was conducted on 25% Pymetrozine suspension （24 mL/667 m2） and the conventional control agent of 10% imidacloprid WP （25 g/667 m2） against rice planthopper to evaluate the therapeutic effect of 25% Pymetrozine suspension agent on rice planthopper. The results show that： 25% Pymetrozine suspension agent on rice planthopper has good prevention effect, and it can in- crease rice yield, reduce the application of labor, and increase economic benefits.
