ABSTRACT:
An apparatus for applying a liquid chemical to plants includes an elongate hollow body which contains a liquid chemical. In use, the hollow body is transported through the plants in a direction transverse to the length of the elongate body. The elongate body includes a row of bottom holes and a row of side holes positioned along the leading side of the elongate body. A canvas cover is tightly wrapped around the elongate body in a double layer and the peripheral side edges of the canvas are sealed. The elongate body is filled with the chemical and an air valve is adjusted to bleed air into the interior of the elongate body. The elongate body is then moved through the field and, by adjusting the position of the elongate body above the ground, the chemical which has seeped into the canvas is wiped onto the plants. In a preferred embodiment, the elongate body is circular and made of a plastic material. Also, the side holes are larger than the bottom holes, and for hilly terrain, the side holes near each end are smaller than the side holes in the middle. A gate valve can also be provided near the middle of the elongate body to prevent the chemical from rushing to one end on hilly terrain.
