通过助剂的筛选,研制出内吸性杀菌剂40%苯醚甲环唑水悬浮剂配方,并研究其防冻剂、研磨时间、冷却水温度、起泡性等因素对悬浮剂稳定性的影响。结果表明,以乙二醇为防冻剂、研磨3 h、常温水浴下、无泡沫的苯醚甲环唑悬浮剂最稳定。 Through the screening of auxiliaries, the formula of systemic fungicide 40% difenoconazole was developed and the effects of antifreeze, grinding time, cooling water temperature, foaming and other factors on the stability of suspending agent . The results showed that the foam-free difenoconazole suspensions were the most stable with ethylene glycol as antifreeze for 3 h at room temperature.
