An improved elongated garden implement having a self-contained sprayer for herbicides. The spray nozzle is attached to the working end of the implement (e.g. near the tines of a rake, the blade of a hoe, etc.). The spray from the nozzle is controlled by a valve mechanism inside the handle of the implement, and is operated by a switch or push button on the outside of the handle. The reservoir of herbicide is pressurized using a pump that is integrated into the end of the handle of the implement. By pumping the slidable end of the handle of the implement, pressure can be built up inside the reservoir. Then, activating the switch opens the valve allowing the pressurized herbicide to spray through the nozzle at the opposite end of the implement. A closable opening may be provided in the side of the implement handle for refilling the reservoir, or the handle itself may be unscrewed and separated to facilitate refilling the reservoir. The elongated handle of the implement allows the nozzle to be held very close to the thing (e.g. weed) to be sprayed, thereby allowing an easy way for the user to reach a distant area and spray only a very small quantity of material. This convenient apparatus helps minimize the annoying interruptions to gardening caused by the encounter of distant weeds, and the excessive stooping and bending required by conventional weed sprayers. The apparatus also avoids waste and inadvertent spraying of healthy plants.

[ I claim:] [1.] An improved garden implement comprising an elongated hollow handle, a working head at the proximal end of said handle, a spray nozzle attached to said handle adjacent said working head, a removable reservoir cartridge containing fluid under pressure adapted to fit inside said handle

[ I claim:] [1.] An improved garden implement comprising an elongated hollow handle, a working head at the proximal end of said handle, a spray nozzle attached to said handle adjacent said working head, a removable reservoir cartridge containing fluid under pressure adapted to fit inside said handle, said cartridge having a closable, deformable pointed end and a flat opposite end, means for opening said handle to accept said cartridge, fluid communication means between the pointed end of said cartridge and said nozzle, biasing means in said handle between said cartridge and said nozzle, and force transmission means at the distal end of said handle in communication with the flat end of said cartridge, whereby as force is transmitted to the cartridge, said deformable end is pushed open allowing the pressurized fluid therein to escape to the outside through said nozzle.
