ABSTRACT:
The instant invention relates to a process for preparing novel insecticide-polymer particles. The process consists essentially of dissolving the insecticide, methomyl, and a polymer in a solvent in which both are soluble. The solution is then comingled with a non-solvent for both the polymer and the methomyl under high shear conditions. A particulate product is formed consisting of irregularly shaped particles having methomyl embedded in a polymer matrix. The irregularly shaped particles may be dispersed, e.g. in water, and sprayed readily into an area of insect infestation.
