ABSTRACT:
A hand-held liquid herbicide applicator for wipingly applying the liquid herbicide on undesired vegetation. The applicator includes an elongated tubular handle for containing a supply of the liquid herbicide with a valve at the lower end of the handle to control the flow of herbicide from the handle to an applicator head carried on the bottom of the handle. The applicator head includes a demountable sponge of special configuration in that it has a porous relatively dense skin which causes even and complete saturation of the entire sponge to prevent uncontrollable liquid flow in one or more localized parts of the sponge.
