ABSTRACT:
A method and apparatus are provided primarily for the application of liquid contact herbicides to plants. A liquid applicator roller is mounted for rotation about a generally horizontal axis and in operative communication with a reservoir of liquid herbicide. The applicator roller is mounted above ground and in position for the peripheral surface thereof to be brought into contact with plants. The applicator roller is moved in the direction generally perpendicular to the axis of rotation of the roller, and powered rotation thereof is effected so that it rotates into contact with plants and continuously transfers liquid from the surface thereof onto the plants, the surface being continuously replenished with liquid from the reservoir. The housing mounting the roller is readily adaptable to mount a hand pushed or pulled unit, or to be mounted on a tractor tool bar. A drive wheel can communicate with a raised surface portion of the liquid applicator roller for effecting rotation thereof. Transfer of herbicide from a liquid pool to the applicator roller can be effected utilizing a sponge or a pair of transfer rollers. The liquid pool is mounted adjacent the axis of rotation of the roller, on one side of the housing.
