Abstract
A pesticidal organotin formulation is a water dispersible solid concentrate comprising at least one pesticidal organotin compound and polyvinylpyrrolidone. The formulation is prepared by dissolving the organotin compound and the polyvinylpyrrolidione in a solvent, followed by removal of the solvent, preferably by evaporation at a pressure below atmospheric pressure to yield the solid concentrate. The formulation may be dispersed in water, either with or without agitation, to yield an aqueous dispersion which may be applied to a locus to combat pests, especially acarids.
