  Agriculturally active materials, such as pesticides, herbicides and the like and a process for microencapsulating said materials. The present invention includes trifluralin having a polymorphic form characterized by a yellow color and a melting point of approximately 41°-- 43° C. The present invention also includes a method of using the yellow polymorphic form of trifluralin as a herbicide. In addition, the present invention includes a method of microencapsulating low-melting agricurally active materials, such as trifluralin. The microencapsulation process comprises the steps of heating a low-melting, water-immiscible, agricurally active material to a molten state. The molten active material is then combined with an aqueous solution of a water-soluble, film-forming polymer at a temperature sufficient to maintain the active material in its molten state. The active material is then dispersed or emulsified in the aqueous solution so that the active material has a primary particle size of between approximately 0.1 and 10 microns. The resulting dispersion or emulsion is then spray dried at a temperature between approximately 50° and 220° C. so as to microencapsulate the active material in the polymer. Compounds for promoting the rapid solidification of the active material are also disclosed.

  农业活性材料，如杀虫剂、除草剂等，以及微囊化上述材料的工艺。本发明包括具有多晶型的三氟拉林，其特征为黄色，熔点约为 41°-43° C，本发明还包括将黄色多晶型的三氟拉林用作除草剂的方法。此外，本发明还包括一种微胶囊化低熔点农业活性物质（如三氟脲）的方法。微胶囊化工艺包括以下步骤：将低熔点、不溶于水的农用活性材料加热至熔融状态。然后，在足以使活性物质保持熔融状态的温度下，将熔融活性物质与水溶性成膜聚合物的水溶液混合。然后将活性材料分散或乳化在水溶液中，使活性材料的主要粒径在 0.1 至 10 微米之间。然后在约 50° 至 220° C 的温度下喷雾干燥所得到的分散体或乳液，以便将活性材料微囊化在聚合物中。此外，还公开了促进活性材料快速凝固的化合物。
