Abstract
Controlled release pesticides are prepared by reacting an isocyanate derivative of a pesticide with a polymer having pendant groups containing a reactive hydrogen to obtain a novel pesticide-polymer system in which the pesticide is chemically bonded to the polymer. Active pesticidal material is released from the pesticide-polymer system by hydrolysis or chemical depolymerization under conditions of use.
