For Use In

Specifically designed for range land and pasture use ,


Spot Application: Spot treatments may be applied at an equivalent broadcast rate of up to 0.22 lb acid equivalent (14 fl oz of Milestone) per acre per annual growing season; however, not more than 50% of an acre may be treated at that rate.

Do not apply more than a total of 0.11 lb acid equivalent (7 fl oz) per acre of Milestone per annual growing season as a result of broadcast, spot or repeat applications.) Spray volume should be sufficient to thoroughly and uniformly wet weed foliage, but not to the point of runoff. Repeat treatments may be made, but the total amount of Milestone applied must not exceed 7 fl oz per acre per year.

To prevent misapplication, spot treatments should be applied with a calibrated sprayer.

  • Milestone Herbicide
    By Roger Harbin on 5/11/2014
    This is my herbicide of choice for western Montana knapweed, oxeye daisy, and other noxious weeds. I divided my property into six-acre segments. A quart covers one segment. I spray one third of the segments each year. Milestone is still quite effective after three years, so this process covers the whole property. I don't need an applicators license and I can spray to the water line of my streams. This product is also used by the State of Montana on their nearby land and roadsides.
