1. A formulation comprising:
- nanoparticles comprising polymer-associated herbicide compound comprising a polymer and a herbicide compound with an average diameter of between about 1 nm and about 500 nm,wherein the polymer is a polyelectrolyte copolymer comprised of between 50 weight percent and 95 weight percent methacrylic acid monomers and between 50 weight percent and 5 weight percent ethyl acrylate or styrene monomers, and the polymer-associated herbicide compound makes up between about 20 weight percent and about 50 weight percent of the formulation;
between about 0.5 weight percent and about 5 weight percent of a dispersant;
between about 0.5 weight percent and about 5 weight percent of a wetting agent;
between about 0.01 weight percent and about 0.2 weight percent of a preservative;
between about 0.05 weight percent and about 5 weight percent of an anti-foaming agent; and
water.
