An apparatus for applying dry herbicides to sewer lines which includes a container for storing a herbicide, a length of tubing, and nozzle means connected to the tubing. Also included are means for propelling herbicide stored in the container through the tubing such that herbicide may be dispersed from the nozzle. Locomotion means are also provided for transporting the nozzle within the interior of a sewer line such that the interior surfaces of a sewer line may be sprayed with a herbicide. In this fashion herbicide may be directed at any flora growing within the sewer line.
