The use of herbicides for control of undesirable vegetation along highway, railroad, and utility rights-of-way has been a valuable tool for many years. As energy and labor have become more expensive so have mowing and hand clearing of brush, and a greater dependence on herbicide use has been created. Today, however, environmental concerns about herbicides are threatening their usefulness for the future. Herbicide programs as they exist today will undoubtedly be cut substantially or eliminated completely in many states. It is becoming increasingly urgent that alternatives to longstanding vegetation maintenance practices be developed. A greater understanding of chemical ecology, and more specifically allelopathy, may well lead to the development of more economical and environmentally sound right-of-way maintenance practices. Allelopathy is defined as any direct or indirect harmful effect by one plant on another through production of chemical compounds that escape into the environment. It is hypothesized that if allelopathy is a wideranging phenomenon involving many plant species, it will be possible to find individual plants that can be used to establish stable communities capable of preventing the encroachment of undersirable species.
