Abstract: An agricultural sprayer, particulary effective for use in orange groves or orchards utilizes a high velocity, high volume axial flow fan which directs air through a plenum chamber in which the air is divided to flow towards opposed lateral openings at the sides of the sprayer. The sprayer is provided with an oscillator for directing the flow of air so that the air flow varies from a substantially downward direction to a substantially upwards direction during the spraying operation. The axial flow fan is mounted relatively high with respect to the ground to avoid the pick up of debris and the like.
