摘要
用XDE-208药剂对褐飞虱若虫进行了田间药效防治试验,结果表明,在试验设计范围内,药后21 d防效达到99.04%~99.51%,防治效果理想,持效期长;且在相同剂量下防治效果随用水量提高而显著提高。
The control efficacy of pesticide XDE-208 on brown planthopper（BPH） nymphs was carried out. The results showed that control efficacy reached 99.04%-99.51% after 21 days under this experiment condition,indicating that the control efficacy of XDE- 208 was ideal and lasted long. And also under the same dosages,control efficacy was improved with the increased water volume.
