因粉剂农药与可湿性粉剂农药物理性不同,使用方法有所区别。一是粉剂农药不能对水使用。粉剂农药是由一种或多种农药原药与陶土、粘土等填料,经机械加工粉碎混合而成的。碎粉末经过200号筛目,粉粒较粗,不易结块,喷撒流动性和分散性好。但粉剂不易被水湿润,也不能分散和悬浮在水
Due to different physical and chemical differences between pesticides and wettable powders, the methods of use are different. First, powder pesticides can not be used on water. Powder pesticide is one or more of the original pesticide and clay, clay and other fillers, crushed by mechanical mixing. Broken powder after 200 mesh, coarse particles, not easy to agglomerate, spray fluidity and dispersion good.
