The composition comprises about 20.0% to 80.0%, by weight, of the finished product, of an inert, non-sorptive, granular carrier, said carrier coated with a pesticidal resin composition containing, as the active ingredient, about 1.0% to 30.0%, by weight, of the finished product, of a pesticide, the technical grade of said pesticide having a dermal LD50, as measured on rats or rabbits, of less than 50 mg/kg; about 5.0% to 40.0%, by weight, of the final product, of a polyvinyl chloride homopolymer or copolymer dispersion resin having a weight average molecular weight of about 200,000 to 400,000 and an inherent viscosity measured by ASTM D 1243 of about 1.0 to 1.32; about 0.1% to 4.0%, by weight, of a stabilizing agent or mixture of stabilizing agents for said resin; and about 0.0% to 40.0% by weight of a secondary plasticizing agent. The compositions are characterized by markedly reduced mammalian toxicity in comparison to the technical grade pesticide. |
