An aqueous, flowable composition containing a high concentration of a solid, essentially water-insoluble, pesticidally-active component homogeneously dispersed therein is prepared by wet-milling the active component in an aqueous matrix together with dispersants. The flowable, pesticidal composition obtained exhibits significantly improved pest control by comparison to that possessed by similar compositions containing air-milled, pesticide components of like average particle size.

A process for preparing a flowable, homogeneous, storage-stable aqueous pesticide composition which comprises successively charging to a chamber equipped with metal balls, water in sufficient quantity to provide, in combination with the other ingredients, 100%, by weight, of finished composition, from 1.0 to 10%, by weight of a non-ionic surfactant, from 0 to 5%, by weight, of a liquid antifoaming agent, from 0 to 10%, by weight, of a freeze-point depressant, and from 10 to 60%, by weight, of an essentially water-insoluble, pesticidally-active component having an average particle size ranging from about 5 microns to over 15 microns; homogeneously mixing the ingredients in the chamber by the shearing action of the rotating metal balls; thereafter adding successively from 0.02 to 1.0%, by weight, of a heteropolysaccharide gum and from 0 to 10%, by weight, of an anti-caking agent and wet-milling the resulting mixture until said gum component is uniformly admixed and the mixture thickens significantly, the total wet-milling time ranging from 1 to 30 hours, the average particle size of the pesticidally-active component in the finished composition being 1.0-5.0 microns.
