1. A microcapsule suspension formulation comprising:
(a) a suspended phase of a plurality of microcapsules having a volume median particle size of from about 1 to about 10 microns, wherein a microcapsule comprises:
(1) a microcapsule wall produced by an interfacial polycondensation reaction between a polymeric isocyanate and a polyamine to form a polyurea shell having a weight percentage of about 0.2 to about 15 percent of a total weight of the microcapsule suspension formulation, and(2) a compound encapsulated within the polyurea shell wherein said compound is 2-chloro-6-(trichloromethyl)pyridine; and (b) an aqueous phase including a compound selected from the group consisting of: ionic stabilizers, dispersants, emulsifiers, antifoams, and biocides. |
