Apparatus for spraying plants and the like comprises a spray tank provided with a nozzle and an intermediate tank which can be connected to a supply of water under pressure. The spray tank is pressurized by connecting it to the empty intermediate tank which is connected to the water supply. The water under pressure from the supply first displaces air from the intermediate tank to the spray tank and then partially fills the spray tank in which the material to be sprayed has been introduced, so as to compress the air that was originally in the spray tank and the air displaced from the intermediate tank, thereby providing sufficient pressure throughout the spraying time. |
