Product Overview

Alligare Triclopyr 4 is an oil-soluble herbicide that controls unwanted woody plants and perennial and annual broadleaf weeds. The active ingredient triclopyr is highly effective in controlling difficult weeds like Canada thistle, gallberry, salt cedar, and wax myrtle. It may be applied through ground or aerial applications. This powerful selective herbicide is specially formulated to easily dilute with water or to be used as an oil-water emulsion. It has less impact on grasses and can be used as foliar and basal treatments. Ideal for use on rangeland, forests, grass pastures, industrial manufacturing and storage sites, fence rows, rights-of-way, ornamental turf, non-crop areas around the farm, grazing areas and establishment, and maintenance of wildlife openings. Ideal for restoring pastures and a solution to seasonably dry wetlands. Compare to Garlon 4 or Remedy.

Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application. For any requirements specific to your State or Tribe, consult the agency responsible for pesticide regulation.

Use Precautions

  • Local conditions may affect the use of herbicides. Consult your local specialist for advice in selecting treatments from this label to best fit local conditions.
  • Avoid direct application to Christmas trees as conifer injury may result. When treating unwanted vegetation in Christmas tree plantations, use sprays directed away from conifers.
  • While Alligare Triclopyr 4 is formulated as a low volatile ester, the combination of spray contact with impervious surfaces (such as roads and rocks) and increasing ambient air temperatures may result in an increase in the volatility potential for this herbicide, increasing risk for off-target injury to sensitive crops such as grapes and tomatoes.
  • Use of this product in certain portions of California, Oregon, and Washington is subject to the January 22, 2004 Order for injunctive relief in Washington Toxics Coalition, et. al. v. EP, C01-0132C, (W.D. WA).

  • Do not make direct applications or allow spray mists to drift onto cotton, fruit or orchard trees, shrubs, grapes, peanuts, soybeans, tobacco, vegetable crops, flowers, citrus, or other desirable broadleaf plants.

Mixing Directions: Apply Alligare Triclopyr 4 foliarly by diluting with water or as an oil-water emulsion. NOTE: An oil-water emulsion performs more dependably under a broader range of conditions than a straight water dilution for woody plant control and is recommended for aerial applications.

Oil-Water Emulsions NOTE: Prior to preparing oil-water emulsion sprays in the mixing tank, conduct a jar test to check spray mix compatibility.

Prepare the oil-water emulsion using diesel fuel, fuel oil, or kerosene plus an emulsifier such as Sponto 712 or Triton X-100.

  • Ground Application: Add oil at a rate of 5 to 10% of the total to the spray mix (up to a maximum of 1 gallon of oil per acre) and use an agricultural spray emulsifier according to mixing instructions below.
  • Aerial Application: Add a 1:5 ratio of oil and water (1 part oil to 5 parts water) to the spray mixture (up to a maximum of 1 gallon of oil per acre) according to the mixing instructions below.

Tank Mixing

Alligare Triclopyr 4 may be applied in combination with labeled rates of other herbicides provided: 

  • The tank mix product(s) are labeled for the timing and method of application for the use site to be treated; and, 
  • Tank mixing is not prohibited by the label of the tank mix product(s).

Tank Mixing Precautions:

  • Read carefully and follow all applicable use directions, limitations, and precautions in the respective product labels.
  • Do not exceed specified application rates. If products containing the same active ingredient are tank mixed, do not exceed the maximum allowable active ingredient use rates.
  • When using spray equipment where the product formulations will be mixed in undiluted form (such as direct injection), special care should be taken to ensure tank mix compatibility.

    Works well but directions unclear

    By Sara on 06/05/2020

    As a homeowner, I've tried a number of ways to get rid of creeping charlie with very little success. This product has definitely shown results, although the directions for application are not very clear. It is definitely designed for commercial use so I think most homeowners will have to do some experimenting. I plan to apply again about 30 days after the first application and increase the concentration just slightly. I applied with a hand sprayer and used a surfactant and was mostly pleased with the results.

    I've been looking for an herbicide that will kill the wild violets that are taking over my turf. I followed directions for mixing and applied Triclopyr 4 with a 2 gallon pump up spray bottle. Results: one week later the Violet's leaves are curling and turning yellow, and the grass (Ky Blue + Fescue) is still intact.

    Getting rid of Alianthus suckers

    By Bob on 08/21/2020

    This stuff really works! So-called Tree of Heaven and some Black Locust trees were cut down in our yard resulting in annoying suckers that seemed to spring up everywhere. I used a 4:1 mix with kerosene to spray on the leaves of the suckers to eliminate them from our yard. This stuff isn't inexpensive, but it even killed the roots of the suckers, thus making it far easier to pull them up, roots and all. Plus, it didn't kill the nearby bushes.

    Excellent for basal bark application

    By K on 09/06/2020

    When mixed with an oil carrier and applied according to the label instructions this product works very well. Note that it is soil active so try to keep if out of the soil so adjacent plants are not damaged. Also note that it takes up to four months for full effect so be patient.

    Wild Violet - Where did you go?

    By John on 09/18/2020

    If you want to destroy some wild violet In your lawn, this is your product. I couldn’t find where I sprayed the violet after two weeks. My neighbor, who borrowed some, would agree. His yard was 50% violet, which has now been completely eliminated.
