has also been described as effective, and Clopyralid, MCPP, and quinclorac as ineffective. have also been described as effective, but sales of both are restricted to professionals. Two applications ten to fourteen days apart are necessary; also, the ability of the surviving plants to regenerate after 24 days can require a second treatment four or five weeks later, and even more followups.

In addition, the timing of application may play a role in the effectiveness of the herbicide, as well as the perception of effectiveness. For instance, fall is usually the best time for use of broadleaf herbicides; however a slow acting herbicide like triclopyr applied in the fall may not appear to have been effective until the next growing season.

Other techniques reported effective are to fertilize with greater than two pounds of nitrogen per thousand square feet annually, and use of the preemergence herbicide, isoxaben. In extremely difficult cases, a short-lived full-spectrum herbicide such as glyphosate is used to kill the entire lawn, and it is reseeded from start.
