ABSTRACT:
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.
