The chloro-substituted benzoic acid compounds discussed here were included with a number of other chemicals tested in 1955, 1956, and 1957 as soil sterilizing herbicides at Hays, Kansas. The experiments were designed to yield information on the effectiveness of various treatments for field bindweed (Convolvulus arvensis) control. Results of the bindweed control studies have been briefly summarized by Phillips (9).
