An effective controlled release pest control composition can use activated carbon as the sole release agent. Liquid pesticide is adsorbed into the interior mesopore and macropore space of the activated carbon. Upon contact with water, the pesticide is slowly displaced from the carbon into the environment for appropriate control. The particulate can be used as is or can be combined with liquid or solid diluents. The particle can be formed into larger composites comprising a granule, a pellet, and an agglomerated particle, etc. A variety of pesticides can be used including insecticides, herbicides, fungicides, growth regulators, etc.
