35%稻瘟灵·己唑醇水乳剂配方研究

Study on Formula of 35% Isoprothiolane·Hexaconazole Emulsion in Water

稻瘟灵与己唑醇复配杀菌剂对水稻三大病害均有良好的防治效果,并具有保护和治疗双重作用,应用前景广阔。本文主要进行了35%稻瘟灵·己唑醇水乳剂产品的配方研究。结果表明,以聚羧酸盐类表面活性剂、农乳0201-B、吡咯烷酮以及黄原酸胶等为乳化分散剂、助溶剂及增稠剂时,产品的稳定性良好,各项指标符合农药水乳剂的要求,在热贮条件下两种农药的分解率均低于5%。

The mixture of isoprothiolane and hexaconazole could control the rice diseases effectively. The formula of 35% isprothiolane ·hexaconazole emulsion in water （EW）was studied in this paper. The re-sults showed that the product which using polycarboxylate as surfactant, 0201-B as emulsion dispersant , pyrrolidone as the solvent, and xanthan gum as the thickener had good performance. The quality indexes of the product reached the level of general EW standards. The decompositions of active ingredients were below 5%after the accelerated storage test.
