Abstract
A herbicide dispensing apparatus utilizes an upright frame attached to a cultivator or other moveable farm vehicle and carries a pair of downwardly angled herbicide applicator arms which overlie a row crop and diverge laterally outwardly from the row. Wicking means is attached to the arms and conveys herbicide outwardly along each arm and applies it by contact to unwanted plants in the path of the arms. The arms are swingably received in sockets in the frame and pivot toward and away from each other so as to adjust the distance of separation between the ends of the arms so that such ends terminate over spaces between adjacent rows of crop, permitting excess herbicide to drop harmlessly into such spaces. A pair of tubes extend from a herbicide reservoir to the applicator arms, and metering clamps are positioned on each tube and cooperate with flow stabilizers within each tube to closely control the rate of herbicide flow through each tube.
