Injection apparatus for automatically applying pest control concentrates and fertilizers into an existing underground irrigation system. Apparatus uses an electronic control system programmed to activate one or more injection pumps and to also operate the zonal flow control solenoids contained in an existing underground or other type of irrigation system. Apparatus includes a single or plurality of storage reservoirs for storing one or more additives with piping to deliver these additives to the existing irrigation system.
