The home gardener should supply himself with a powder gun. If one must be restricted to a single implement, however, it will be best to get one of the hand-power, compressed-air sprayers. These are used for applying wet sprays, and should be supplied with one of the several forms of mist-making nozzles, the non-cloggable automatic type being the best. For more extensive work a barrel pump, mounted on wheels, will be desirable, but one of the above will do a great deal of work in little time. Extension rods for use in spraying trees and vines may be obtained for either.
