Abstract of the Disclosure A vineyard air sprayer includes an axial fan type of blower assembly which is vertically mounted upon a trailer rearwardly of a spray tank. The blower assembly has a cylindrical outer shell having an annular discharge ring mounted to the bottom end thereof. An inner shell is coaxially mounted within the outer shell, and a truncated annular diffuser is secured to the bottom end of the inner shell in a coaxial relationship therewith. The outer edge of the diffuser is spaced from the outer edge of the discharge ring to form two arcuate discharge openings at opposite sides of the blower assembly. The diffuser includes an upwardly projecting annular lip portion which is truncated by a vertical wall at its front end. The edge of the lip at each side of the diffuser is cut along a convolute helical path so as to be highest at the rear end of each discharge opening, to slope downwardly and for- wardly therefrom to a point where the lip is notched away, and to slope upwardly from such notched portion until its juncture with the vertical wall at the front of the discharge opening. Spray nozzles are positioned in each discharge opening to deliver atomized spray solution to the air blast emanating therefrom. The air blast generated from each discharge opening is moderated by the convolute helical edge of the diffuser so as to impinge upon the foliage being sprayed with varying angles of impingement as the sprayer is pulled by such foliage. Air flow over the notched portions of the diffuser is directed toward the base portions of the -la- plants being sprayed. -1b-
