Remedy Ultra Triclopyr Herbicide
09/14/25
Remedy Ultra Triclopyr Herbicide, manufactured by DOW/CORTEVA, is a powerful, long-lasting herbicide for rangeland and pasture brush control in outdoor residential and commercial areas. Land managers and agricultural workers use Remedy to kill more than 35 different types of brush, weeds, and invasive trees.
While this low-odor product works well on its own, Remedy Ultra Triclopyr Herbicide also mixes well with other herbicides. So where mixed brush and broadleaf weeds dominate, consider tank-mixing Remedy Ultra with other popular weed killers for broader-spectrum control and residual broadleaf weed control.
Remedy Ultra Herbicide, with its powerful active ingredient, triclopyr, can address the situation at 60.45% if weeds, trees, and brush interfere with operations.
Tools Needed
Remedy Ultra Triclopyr Herbicide should be diluted in a sprayer tank before use. Depending on the areas being treated, the product can be mixed with surfactants, drift control agents, or oil for maximum results. A pump sprayer or backpack sprayer will do for smaller applications. A spray rig is recommended for larger applications.
Do not apply with a mist blower.
How to Use
- Step 1: Determine how much Remedy Ultra Triclopyr Herbicide you will need by calculating the square footage of the treatment area. To do this, measure the treatment areas' length and width in feet, then multiply them together (length X width = square footage). To find acreage, divide the square footage by one acre (square footage / 43,560 sq. ft. = acre). For spot treatments, Remedy Ultra Triclopyr Herbicide should be mixed in a 1 to 1.5% solution in water (1 to 1 1/2 gallons of product in 100 gallons total spray mixture). For broadcast applications, apply 1 to 2 pints of product per 10 gallons of water per acre for small weed control or up to 1 1/2 quarts of product per 10 gallons of water per acre for deep-rooted perennial and susceptible woody species control.
- Step 2: Fill the spray tank with half the required water. Then, add Remedy at the appropriate rate based on your calculations for the weed you are trying to treat. Add a selected surfactant as suggested by the label and agitate the sprayer to make sure the solution is mixed well.
- Step 3: Spray the application to targeted areas where weeds grow, preferably on a fan spray setting for uniform coverage. If you are trying to control an invasive tree, you will need an oil-based carrier and will need to perform a cut-stump treatment. Apply enough spray to wet the trunk's lower 12 to 15 inches, including the root collar. Spray a coating like you would spray paint.
Where to Use
Remedy Ultra Herbicide can be used on rangeland, permanent grass pastures, and conservation reserve program (CRP) acres (including fence rows and non-irrigation ditch banks within these areas).
Do not apply this product directly to, or otherwise permit it to come into direct contact with, cotton, grapes, peanuts, soybeans, tobacco, vegetable crops, flowers, citrus, or other desirable broadleaf plants.
When to Use
For best results, apply Remedy Ultra Herbicide when plants are actively growing, typically early in the summer. Application in late summer or periods of dry weather, when plants are not actively growing, may result in unsatisfactory control.
Do not reseed treated areas for a minimum of three weeks after treatment.
Safety Information
Remedy Ultra Herbicide is safe to use around children, pets, and livestock when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing and applying this product.
During the season of application, withdraw livestock from grazing treated grass at least 3 days before slaughter. Do not harvest hay for 14 days after application.
Do not allow others to enter the treated area until sprays have dried.
Special Considerations
Low-volume basal and cut-stump applications require an oil-based carrier. Be sure pumps and hoses are resistant to oil-based carriers. Wands and spray tips also should be chemical-resistant. Adjustable tips give you more control when making individual plant treatments and there should be a cut-off at the tip to avoid wasting product (such as a strainer and check ball valve or low volume wand).
Apply no more than 1/2 gallon (2 lb ae) of product per acre per growing season on rangeland, permanent grass pastures, and conservation reserve program acres, including fence rows and non-irrigation ditch banks within these areas, or any area where grazing or haying is allowed.
Remedy Ultra Triclopyr Herbicide may be used at rates up to 8 quarts (8 lb ae) per acre per year on non-grazed portions of conservation reserve program acres, including fence rows and non-irrigation ditch banks. Portions of grazed areas that intersect treated rangeland, permanent grass pastures, and conservation reserve program acres may be treated at up to 8 lb ae per acre if the area to be treated on the day of application comprises no more than 10% of the total grazable area.
