CA 2313068

An apparatus for applying agricultural liquid chemical to plants by contact comprises a liquid chemical reservoir and a porous conduit extending lateral to the direction of travel of the apparatus and located at a vertical height above the ground. The conduit wall is operative to allow liquid chemical under pressure in an interior of the porous conduit to pass through the conduit wall. An absorbent wiper covers the porous conduit and absorbs liquid chemical and becomes wet such that contact with the wiper results in transfer of liquid chemical onto a plant. A pump draws liquid chemical from the reservoir and delivers same under pressure to the porous conduit. A control adjusts the liquid chemical pressure in the porous conduit from zero to a flow pressure. The apparatus may be manufactured as a kit for attachment to a conventional sprayer.
