ABSTRACT:
A method and apparatus for foliar spraying liquid composition such as pesticide, aqueous fertilizer solution, and/or herbicide, onto foliage of vegetation. In a preferred embodiment, while spraying a spray stream of liquid composition at 10 to 75 pounds per square inch pressure from an orifice having a cross-sectional area of from about 0.0000948 to about 0.0323000 square inches to strike vegetation foliage within from about 5 to about 15 inches, with a plurality of gas-directing vents spaced-apart on opposite sides of the orifice but not circumscribing the orifice, the gas-directing vents each being directed to impinge air upon the spray stream within the 5 to 15 inches, the gas-directing vents being angled toward the spray stream at angles from about 0 to about 50 degrees relative to a second axis extending from the gas-directing vent that is parallel to a first axis following the spray stream, with baffles on opposite sides of the gas-directing vent for each thereof, the baffles being angled divergingly outwardly from the axis in which directed at angle ranging from 0 to about 20 degrees, a plurality of spray orifices each with its plurality of gas-directing vents, are mounted and spaced-apart from one another along an open boom and adapted to spray laterally and/or backwardly, while a support structure mounting the boom(s) moves the spray vents substantially horizontally forwardly by way of a vehicle advancing at a speed of from about 1 to 10 miles per hour.
