30%矮壮素·多效唑悬浮剂的研制

Formula of 30% Chlormequat and Paclobutrazol SC

[目的]探讨30%矮壮素·多效唑悬浮剂的研制配方。[方法]为避免或减少多效唑对植物产生药害,增强调节作用和提高药效,进行了的研究。通过对润湿分散剂、增稠剂、防冻剂、消泡剂等的筛选以及冷、热贮试验,研究矮壮素和多效唑复配悬浮剂的最佳配方。[结果]30%矮壮素·多效唑悬浮剂更佳配方为:20%矮壮素、10%多效唑、2%GY-WS03、4%DS-505、0.15%黄原胶、1.0%硅酸镁铝、3%乙二醇、0.5%DF-1550消泡剂、0.1%卡松,去离子水补足100%。对所得悬浮剂进行质量指标测定,结果符合悬浮剂国家标准。[结论]试验所得30%矮壮素·多效唑悬浮剂配方可行。

[ Objective ] The aim was to explore the formula of 30% chlormequat and paclobutrazol SC. [ Method ] We studied the formula of chlormequat and paclobutrazol SC through the screening of wetting dispersants, thickening agents, antifreeze agents and anti-foaming agents as well as cold and heat storage tests. [ Result ] The best formula for 30% chlormequat and paclobutrazol SC was as followed chlormequat TC 20% , paclobutrazol TC 10% , GY-WS03 2% , DS-505 4% , xanthan gum 0. 2% , defoaming agent DF-1550 0. 5% , magnesium silicate alumi-num 1.0% , ethylene glycol 3% , preservatives 0. 1% , and deionized water making up to 100%. All specifications of 30% chlormequat and pa-clobutrazol SC conformed to the requirements of SC. [ Conclusion] The best formula for 30% chlormequat and paclobutrazol SC is feasible.
