Abstract
A herbicide applicator has an inclined underside surface supported at a selected elevation and slope with respect to the ground. Liquid herbicide is fed at a variably controlled rate to an upper edge portion of the inclined underside surface, and the herbicide flows down the underside surface without dripping before reaching the lower edge portion of the underside surface. Preferably, the underside surface is provided by a durable, non-absorbent, structural-grade material that has been roughened to increase its liquid storage capacity, for example, by grooves, indentations, or pockets. Preferably, liquid herbicide is uniformly fed to the underside surface by a distributor having a perforated tube and a strip of porous plastic sealed within a channel so that liquid fed to the tube must exit through the pores in the porous plastic strip. Preferably, herbicide is collected at the lower edge portion of the underside surface by a rope-wick or other absorbent material, and any excess is removed by a drain or a suction line. For applying herbicide to a wide swath of vegetation, a number of rigid panels are hinged together, or a wide semi-flexible panel is drawn by draw bars connected to the panel by a network of flexibly-connected braces.
