How fast does Milestone work, and how long does the control last?
Milestone is primarily a postemergence herbicide, but it has excellent preemergence soil residual activity on many important weeds (see label for a complete list). Milestone™ herbicide can be applied to weeds at any stage of growth, but specific weeds may have optimal growth stages for control (see label). Within hours or days of application, the stems and leaves of many labeled weeds will stop growing and turn brown. Most annual susceptible weeds will be controlled within four to eight weeks after application; however, complete control of main stems and roots may take longer. Because of its residual activity, control can last all season long, or into the season after application on certain weed species.
