Milestone Herbicide

Free Shipping on All Orders

The most flexible herbicide available, Milestone offers excellent invasive weed control, across a wide variety of use sites. It does so with little-to-no damage to grasses, forbs or other key members of the native plant community, allowing you to restore native habitats to their full potential.

Milestone Herbicide is used for control of susceptible weeds and certain woody plants, including invasive and noxious weeds, on rangeland, permanent grass pastures (including grasses grown for hay*), Conservation Reserve Program (CRP) acres, non-cropland areas including industrial sites, rights-of-way (such as roadsides, electric utility and communication transmission lines, pipelines, and railroads), non-irrigation ditch banks, natural areas.

Target Pests

Broad-spectrum control of problem weeds including noxious and invasive broadleaf weeds and sensitive woody plants

For Use In

Specifically designed for range land and pasture use


Application Methods

Apply the specified rate of Milestone as a coarse low-pressure spray. Do not apply this product with mist blower systems that deliver very fine spray droplets. Spray volume should be sufficient to uniformly cover foliage. Increase spray volume to ensure thorough and uniform coverage when target vegetation is tall and/or dense. To enhance foliage wetting and coverage, an approved non-ionic agricultural surfactant may be added to the spray mixture as specified by the surfactant label.

Ground Broadcast Application: Higher spray volumes (greater than 10 gallons per acre) generally provide better coverage and better control, particularly in dense and/or tall foliage.

Aerial Broadcast Application: Do not apply less than 2 gallons per acre total spray volume. Five gallons per acre or greater will generally provide better coverage and better control, particularly in dense and/or tall foliage.

High-Volume Foliar Application: High volume foliar treatments may be applied at rates equivalent to a maximum of 7 fl oz per acre per annual growing season. Use sufficient spray volume to thoroughly and uniformly wet foliage and stems.

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.

Mix Rate

Mixing Instructions

Mixing with Water: To prepare the spray, add about half the required amount of water in the spray tank. Then, with agitation, add the specified amount of Milestone and other registered tank mix herbicides. Finally, with continued agitation, add the rest of the water and additives such as surfactants or drift control and deposition aids.

Addition of Surfactants or Adjuvants on All Labled Use Sites: The addition of a high quality non-ionic surfactant (of at least 80% active ingredient) at 0.25 to 0.5 % volume per volume (1 to 2 quarts per 100 gallons of spray) is recommended to enhance herbicide activity under adverse environmental conditions (such as, high temperature, low relative humidity, drought conditions, dusty plant surfaces) or when weeds are heavily pubescent or more mature.

Tank Mixing with Other Herbicides: Milestone at rates of up to 7 fl oz per acre may be mixed with labeled rates of other herbicides registered for application on all labeled use sites. Milestone may be applied in tank mix combination with labeled rates of other herbicides provided: (1) the tank mix product is labeled for the timing and method of application for the use site to be treated and (2) mixing is not prohibited by the label of the registered tank mixed products, and (3) that the tank mix combination is physically compatible (see tank mix compatibility testing below). When tank mixing, use only in accordance with the restrictions, precautions and limitations on the respective product labels.

Active Ingredient

Aminopyralid 40.6%

How long should livestock be kept away after from a treated section?
Bruto K on Mar 22, 2018
BEST ANSWER: • Grazing and Haying Restrictions: There are no restrictions on grazing
or grass hay harvest following application of Milestone at labeled rates.
Cutting hay too soon after spraying weeds will reduce weed control.
Wait 14 days after herbicide application to cut grass hay to allow
herbicide to work. Do not transfer grazing animals from areas treated
with Milestone to areas where sensitive broadleaf crops occur without
first allowing 3 days of grazing on an untreated pasture. Otherwise,
urine and manure may contain enough aminopyralid to cause injury to
sensitive broadleaf plants.
• Grazing Poisonous Plants: Herbicide application may increase
palatability of certain poisonous plants. Do not graze treated areas until
poisonous plants are dry and no longer palatable to livestock.

I have St Johns Wort invading my lawn. Will Milestone kill the St. John's Wort and not the lawn??
RC on Jun 1, 2017
BEST ANSWER: St. Johnswort can be
difficult to eradicate with herbicides because of its
extensive root system, but control of new or small
infestations can be accomplished. In pasture,
rangeland, and non-cropland sites, foliar
applications of 2,4-D at 2 quarts per acre will
destroy the plant in seedling and pre-flowering
stages. Spring application of one quart per acre of
picloram is also effective and recommended. Note:
picloram is a restricted use herbicide in Nevada and
as such can only be purchased and applied legally
by a certified pesticide applicator. To control St.
Johnswort after emergence, an application of
metsulfuron at one ounce per acre can be effective.
Repeated applications may be needed. Metsulfuron
should be used with caution. It is persistent in
alkaline soils and can affect the establishment of
broad-leaved crops and some grasses for months
following treatment. But it is listed as a weed controlled with Milestone, 5 to 7 ounces per acre.

Will Milestone kill everything?
sandy on Oct 18, 2016

certain woody plants and vines.
does it work on scotch broom
dw on Apr 16, 2016
BEST ANSWER: Use Milestone mixed with Triclopyr 4 for best results that do not require you to spray the entire plant. Adding a surfactant with the mixture should help. Make sure to minimize drift when spraying by using large particle sizes and not spraying when it is windy. Milestone can damage other vegetation.

Excellent Selective Herbicide
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.
