Abstract
Abstract A resinous herbicidal compound is provided in the form of a roller. The herbicide may be applied in lawns and gardens without the danger of being spread by wind or washed away by rain or dew. The herbicidal compound comprises a selected chemical herbicide or a number or herbicides homogeneously dispersed in a synthetic wax carrier. The synthetic wax is hard to break down by natural process, thus enabling the herbicides to remain on the weeds to control their growth.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
134 words
A device for applying a selected herbicide to weeds from a roller having a synthetic wax base impregnated with said herbicide, comprising an elongated handle having a longitudinal axis, a U-shaped bracket transversely secured at one end of said handle, said bracket being made of a resilient rod element and having two spaced leg portions with free ends bent towards each other to form axes operative for mounting said roller rotatably thereon, two cylindrical containers slidably and removably mounted on said elongated handle, said cylindrical containers being substantially parallel to the axis of said handle, said cylindrical containers having two open ends covered by removable caps, one of said containers being adapted for holding said roller when the device is not in use and the other container being adapted for holding a replacement roller.
