A PROCESS FOR THE PREPARATION OF PELLETIZED PESTICIDAL COMPOSITION HAVING IMPROVED DERMAL MAMMALIAN TOXICITY, IMPROVED INSECTICIDAL ACTIVITY AND EXTENDED RESIDUAL EFFECTIVENESS, FOR CONTROL OF SOIL BORNE PESTS

摘要

A pesticidal composition comprising: about 1.0% to 65.0%, by weight, of a pesticide, the technical grade of said pesticide, having an oral and/or dermal LD50, as measured on rats or rabbits, or less than 50 mg/kg; about 5.0% to 60.0%, by weight, of a polyvinylic dispersion resin having a weight average molecular weight of about 200,000 to 400,000; about 0.2% to 2.0%, by weight, of a heat stabilizing agent or mixture of heat stabilizing agents for the resin; about 0.0% to 1.0%, by weight, of a lubricant; about 0.0% to 50% by weight of a secondary plasticizing agent; about 0.0% to 80.0%, by weight, of a mineral additive; and about 2.0% to 30.0%, by weight, of precipitated silica, a sorptive carrier; wherein said pesticidal composition is a solid and has a reduced mammalian toxicity.
