ABSTRACT:
Dimensionally-stable porous materials such as porous plastic are used in a variety of ways to provide uniform distribution and application of liquids to vegetation. Porous plastic can be readily cut, sawed and drilled to provide liquid distribution channels and various applicator shapes. Porous plastic is easily glued or welded for joining to other materials. Rods, tubes and handles are easily inserted into the porous plastic, and selected areas of the porous surfaces are readily sealed with glue or by melting to confine liquid application to selected areas. The pore size, preferably in the range of 5 to 200 microns, can be selected in accordance with the viscosity of the liquid and the desired rate of flow and pressure. Porous plastic can be highly abrasion resistant, which is especially useful for constructing applicators which rest upon the ground or pavement. Where abrasion is not a problem, the porous plastic may serve to distribute liquid to a soft absorbent applicator such as a sponge. Unitary applicators are readily fashioned from a block of porous plastic by forming a connection to a sprayer nozzle or squeeze bottle, drilling a hole to provide an internal distribution channel, and sealing surfaces that are not intended to deliver liquid.
