A pesticidal composition comprising: about 2.0% to 30.0%, by weight, of a pesticide, the technical grade of said pesticide having an acute dermal LD50 value, measured on rats or rabbits, of less than 50 mg/kg; about 5.0% to 20.0%, by weight, of a polyvinyl chloride or polyvinyl chloride/vinyl ester copolymer or homopolymer having a weight average molecular weight of about 200,000 to 400,000 and an inherent viscosity, as determined by ASTMD 1243, of about 1.00 to 1.32; about 5.0% to 15.0%, by weight, of a secondary plasticizing agent; about 0.3% to 2.0%, by weight, of a heat stabilizing agent for said resin; about 0.5% to 2.0%, by weight, of a surface active agent; about 40.0% to 80.0%, by weight, of a solid sorptive carrier; about 0.0% to 2.0%, by weight, of a drying agent and lubricant; and about 0.0% to 6.0%, by weight, of a deactivator; wherein said pesticidal composition is a solid sorptive granular pesticidal resin composition. The compositions are characterized by markendly reduced mammalian toxicity in comparison to the technical grade pesticide. |
