Abstract
Controlled release pesticide-polymers are prepared by reacting a polymer having a pendant group containing a reactive hydrogen with a chloroformamide derivative of a pesticide. In a preferred embodiment, metribuzin chloroformamide is prepared by reacting metribuzin with phosgene at a temperature of about 40.degree. C. The metribuzin chloroformamide is then reacted with cellulose to form a pesticide-polymer from which the metribuzin is released under use conditions by hydrolytic degradation of the carbamate bond attaching the metribuzin to the polymer.
