ABSTRACT:
Various liquid or low melting pesticide and herbicide formulations, previously formulated with organic solvents, are combined with a polymer in solution and co-precipitated to form a polymer complex which captures the pesticide or herbicide yet exists as a solid at ambient conditions. By preparing the pesticide or herbicide formulation as a solid complex, storage and handling of the formulation is possible without the potential for organic solvent emission. When the solid polymer complex is placed in water, a stable aqueous dispersion of the pesticide or herbicide is achieved as the polymer inhibits flocculation, with approximately 100% recovery of the pesticide or herbicide.
