A device for rapid inoculation with bacterial plant pathogens consists of a fan nozzle and petcock valve attached to a cordless electric grass clipper. Inoculum is contained in a pressurized tank. The inoculum mist created by the nozzle wets the clipper blades, which introduce the bacterial cells into leaf wounds. The inoculator has been used successfully in the greenhouse and field for several host-pathogen combinations.
