ABSTRACT:
A system for the disinfection of prune branches or vines shoots includes a pair of shears having blades hinged by a pin. A specially shaped thin blade is fastened to the pin for holding a nozzle located on the cutting edge of the cutting blades. Disinfectant liquid is contained under pressure in a tank and is delivered to the nozzle through a valve attached to the body of the shears and actuated by a lever that also controls operation of the shear blades. Pressurized liquid disinfectant is delivered concurrently with the shearing action of the blades. All components for disinfectant delivery are external to the shear body and blades and detachable therefrom.
