Abstract
Abstract There are disclosed methods and compositions for the controlled release of pesticides by using a mixture comprising (a) a carbinol-containing organic polymer, (b) a crosslinking agent for said polymer consisting essentially of a hydrolyzable silane or an organopolysiloxane containing hydrolyzable silane groups or partial hydrolyzates thereof, and (c) a pesticide.
