Abstract
The present invention includes a herbicide having a phytocidal effect on roots and the like, and a foaming agent. The foaming agent consists of a gas releasing compound and a surfactant or detergent. To inhibit the growth of flora in or around sewer lines this mixture may be flushed into a sewer line. The gas releasing compound causes the surfactant or detergent to foam, and the foam acts as a carrier of the herbicide through the sewer line. Roots or the like growing within the sewer line are coated with the herbicide carrying foaming agent.
