  • Patent number: 6018907
    Abstract: An apparatus for the application of a liquid chemical treatment to plants in a field. The apparatus includes a movable framework and first and second spaced-apart depending portions mounted upon the framework for providing a space extending longitudinally of the framework. First and second air displacers are carried by the first and second depending portions for creating first and second opposed streams of air in directions at an angle to the longitudinal axis. The air displacers are positioned on the depending portions so that the first and second opposed streams of air are longitudinally offset from each other. Nozzles are carried by the framework for introducing the liquid chemical treatment into the streams of air produced by the air displacers. The streams of air caused the plants to bend to and fro as the plant passes through the space so as to permit the chemical treatment to reach the underside of the plants. A method for using the apparatus is provided.
