摘 要:[目的]比较30%苯噻酰草胺泡腾片剂、飘浮型漂浮粒剂和先沉后浮型漂浮粒剂配方、扩散性能和田间防效。[方法]通过配方筛选确定配方组成;在实验室模拟条件下研究扩散性能;比较水稻田稗草的田间防效确定防效差异。[结果]3种制剂润湿剂和分散剂均选择WET/P+U-Na+D425;在水面没有障碍物时飘浮型漂浮粒剂的扩散性能最优;由于稻田秸秆障碍物影响,2种漂浮粒剂除草效果不佳。[结论]洁净的水稻田优选飘浮型漂浮粒剂;有秸秆障碍物的水稻田泡腾片剂效果最好。[Aims] This study aims to evaluate the diffusion properties and the control effect for barnyard grass of mefenace 30% effervescent tablets, floating granules and sink floating granules. [Methods] The composition of three formulations were determined by screening. Diffusion properties were studied under laboratory simulation conditions.The control effect of barnyard grass in paddy field was studied to determine the difference of control effect. [Results] The humectant and dispersants of the three formulations were all WET/P + U-Na + D425. The conventional floating granule had the best diffusion when no obstacles on the surface of water. Two kinds of floating granule were poor because of obstacles on the surface of water. [Conclusions] Floating granule was preferred for clean paddy field. Effervescent tablet was the best for paddy field with straw obstacle.
