本文介绍了种衣剂加工及实验理论依据,并采用优化组合法对湿润分散剂的复配体系及其它助剂进行了筛选,对毒死蜱.多菌灵.咪鲜胺20%悬浮种衣剂的配方进行了研究,简述了该剂型的特点、配方选择和贮存稳定性,并确定了较佳配方组成、配制方法及其质量控制指标。试验结果表明,该产品悬浮率90%以上,热贮(54℃±2℃,14d)分解率合格,产品各项指标符合悬浮剂种衣剂的要求。
In this paper, the seed coating processing and experimental theoretical basis is introduced, and the compounding system of wetting and dispersing agent and other additives are screened by the optimized combination method, and the effects of chlorpyrifos, carbendazim and prochloraz 20% The formula was studied. The characteristics of the formulation, the choice of formulation and the storage stability were described. The composition of the formulation, formulation method and quality control index were also determined. The test results show that the product suspension rate of 90% or more, thermal storage (54 ℃ ± 2 ℃, 14d) decomposition rate of qualified products meet the requirements of the indicators of the suspension coating agent.
