摘　　要：[目的]探讨15%恶霉灵悬浮种衣剂的研制配方,为恶霉灵的推广和应用提供参考。[方法]采用湿式超微粉碎法制备了15%恶霉灵悬浮种衣剂,并通过对成膜剂、增稠剂、乳化剂、分散剂、防冻剂进行筛选确定了优化配方。[结果]15%恶霉灵悬浮种衣剂的优化配方为:15.0%恶霉灵、3.0%PVA、5.0%602#、3.0%木钙、0.2%黄原胶、4.0%乙二醇、0.5%玫瑰精、余量为水。经低温[(0±2)℃,7 d]和热贮[(54±2)℃,14 d]稳定性试验,制剂外观无明显分层,水中分散性良好,各项指标均符合悬浮种衣剂相关标准。[结论]为恶霉灵悬浮种衣剂的开发奠定了基础。[Objective] The formulation preparation of 15% Hymexazol seed-coating was explored to provide reference for application and population of the agent. [Method]The experiment in the screening of such effective adjuvant as film forming agent,thickening agent,emulsifying agent,dispersing agent and anti freezing agent was conducted according to different indicators with the method of wet milling. Based on the indicators,optimum was obtained. [Result] After primary screening,the best determined formula was as follows： Hymexazol 15. 0%,PVA 3. 0%,602# 5. 0%,wooden calcium 3. 0%,xanthan gum 0. 2%,ethylene glycol 4. 0%,rose essence 0. 5%,with additional water up to 100%. The results indicated that under the condition of（ 0 ± 2） ℃ for 7 d and（ 54 ± 2） ℃ for 14 d,the character of formed membrane was perfect which was in accordance with the experimentally relevant determined standards. [Conclusion]The results lay the basis for the development of 15% Hymexazol seed-coating.
