ABSTRACT:
An applicator for dispensing herbicides to weeds. It has a long handle which supports a herbicide supply container at the top. The other end of the handle supports a horizontal member which has a relatively flat sponge assembly which receives herbicide from the long hollow handle which is connected to the herbicide supply reservoir. A roller assembly is supported from the lower end of the handle and has a roller arm so that movement of the roller arm causes the roller to roll across the surface of the sponge assembly. A hand operated lever at the top of the handle rotates the roller arm through a pull string. In another embodiment, the flat herbicide receiving pad is supported from an axle between two wheels and the rollers are supported in a reel type assembly.
