Controlled release pesticide-polymer systems are prepared by the polymerization of vinyl monomers containing pendant pesticides. The vinyl monomers are prepared by reacting an acrylic acid derivative with a pesticide or a pesticide derivative having an active hydrogen. The pesticide-polymer systems prepared from the pesticide vinyl monomers release the active pesticide material by hydrolysis or chemical depolymerization under conditions of use.
