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. degree. -43. degree. 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 agriculturally active materials, such as trifluralin. The microencapsulation process comprises the steps of heating a low-melting, water-immiscible, agriculturally active material to a molten state. The molten active material is then combined with an aqueous soluion 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.

Pendimethalin microencapsulated in a microcapsule comprised of a water-soluble film forming polymer. The present invention also includes a method of microencapsulating low-melting agriculturally active materials, such as pendimethalin. The microencapsulation process comprises the steps of heating pendimethalin to a molten state. The molten pendimethalin is then combined with an aqueous solution of a water-soluble, film-forming polymer at a temperature sufficient to maintain the pendimethalin in its molten state. The pendimethalin is then emulsified in the aqueous solution so that the pendimethalin 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. degree. C. and 220. degree. C. so as to microencapsulate the pendimethalin in the polymer. Compounds for promoting the rapid solidification of the pendimethalin am also disclosed.
