Abstract: A system for aerial spraying of agricultural crops or the like in which droplets of a controlled size are formed and discharged onto the ground instead of a fine spray. A system is provided for reducing pressure before delivery of the liquid to the discharge nozzles. The nozzles are directed so that the droplets are impelled by the air stream from the upper part of the nozzle structure and are then affected by the air stream and gravity in furtherance of the desire for droplets rather than micron-sized spray mists which too readily drift away from the desired area to be covered.
