Effective, yet selective

Milestone® herbicide goes easy on desirable species, including most forage grasses and many deciduous trees, forbs and other plants. It also helps restore diversity in areas overrun by many noxious and invasive weeds without posing a long-term threat to many of the plants that help comprise that diversity.

No grazing restrictions

Milestone has no grazing restrictions for any type of livestock or wildlife, including lactating dairy animals, beef cattle, sheep, goats and horses.

Low use rates

Milestone controls many annual, biennial and perennial weeds at low use rates (4 to 7 ounces per acre). It also provides excellent postemergence and season-long residual control. And it can be applied up to the water’s edge and control weeds where many species often thrive.
