Although not all herbicides were completely effective in this study, various ones performed well, including atrazine and non-atrazine treatments. The atrazine treatments cost less than most other treatments. The sequential application strategy was consistently better than a single application because the postemergence followup treatment controlled the escapes and second flushes. Single treatments were at a disadvantage in that regard; however, several preemergence, non-atrazine herbicide treatments were noteworthy in their performance.
