This paper discusses an optimized preparation of an isoprothiolane 70%wettable powder （W-P） formulation, not previously reported either in or outside China. The characteristics, ingredient, preparation method, storage stability, and methods of this formulation were researched. The formulation met all criterion require for a wettable powder, including a suspension rate of over 90%, a dispersion time of less than 1 min, and an active ingredient decomposition rate of less than 5% in 60 days at （40±42）℃.[稻瘟灵 著者文摘]
