Abstract
A grove sprayer apparatus has a wheeled vehicle having a pump and a tank mounted thereon with the pump operatively connected to the tank. An upwardly extending hollow mast is attached to the vehicle and is operatively connected through the pump to the tank for the passage of liquid therethrough. A plurality of vertically spaced, horizontal, nozzle bearing boom arms, each having at least one operatively connected liquid control valve, are flexibly mounted to the mast such that spray is activated as the arms contact passing trees. The boom arms contact the passing trees in a manner profiling their aisle periphery surface and thus positioning the spray nozzles in the foliage such as to provide a full, saturating spray mist within the tree by directing the spray from the tank, through the mast, through the booms, and out the nozzles. As the spray machine continues forward and leaves the tree, the foliage pressure of that tree is released, and the booms return to their laterally, peripendicular off-position, thus deactivating the spray valves and stopping all spray generation outside the tree whereby no spray is generated in the outer atmosphere.
