Abstract: A spray boom and vessel apparatus is disclosed having one or more spray nozzles adjustably mounted along the axes of a plurality of independent spray booms. The spray booms are releasably supported upon a boom frame in horizontal, parallel relation to each other. The boom frame is releasably supported by a vessel and valve frame, which also supports a plurality of vessel and valve assemblies. Each vessel and valve assembly is in fluid-flow connection with the nozzles of one of the spray booms and a source of pressurized air. The vessel and valve frame is releasably mounted on a vehicle frame, which is pivotally attached to a vehicle.

Abstract: An improved multi-boom field spraying apparatus designed to spray in a sequential manner one or more of a plurality of liquids to a selected spray zone among a number of spray zones is described. The apparatus contains a novel spray, agitate air and rinse system. A novel spray boom and vessel apparatus are also described.
