Why Use Garlon™ XRT?

  • Woody Species. Broad spectrum control of deciduous woody species, also with activity on broadleaf weeds.
  • Innovative Formulation. New higher-load formulation reduces use rates and packaging.
  • Fast Acting. Quick visual signs of control.
  • Reliable. Trusted tool for utility and forestry managers.


Among the woody plants controlled at the lower rate are:

  • Alder
  • Ash
  • Aspen
  • Basswood
  • Beech
  • Birch
  • Blackberry
  • Buckthorn
  • Cherry•
  • Chokecherry•
  • Cottonwood

  • Locust
  • Maples
  • Mulberry
  • Oaks•
  • Poison
  • Pines•
  • Poplar
  • Red maple•
  • Raspberry•
  • Sassafras
  • Sumac
  • Sycamore
  • Tamarack
  • Wild rose
  • Willow
  • Witchhazel

•These species may require treatment at the higher rate and may need to be retreated the following year, particularly if the original treatment was made at the lower rate.

Rates and Packaging

  • Garlon XRT is available in 2x10L cases and 110L drums.
  • Broadleaf weed control
    • Mix 2.5 to 5 L of Garlon XRT Herbicide in a minimum of 200 L of water per hectare to ensure uniform coverage.
  • Broadleaf Weed Control
    • Mix 0.6 to 2.5 L of Garlon XRT Herbicide in a minimum of 200 L of water per hectare to ensure uniform coverage.
  • Ground Equipment (broadcast) Applications:
    • Single Stem Foliar: For control of woody plants up to 2.5 m in height, use Garlon XRT Herbicide at rates of 2.5 to 5 L in enough water to make 1000 L of spray solution. Use the higher rate for late summer application when growth rates are reduced or when hard-to-control species are present. Spray brush to the point of runoff. Coverage should be thorough to wet all foliage.
    • Low Volume Foliar: For control of woody plants up to 2.5 m in height use this technique with knapsack or backpack sprayers equipped with flat fan or solid cone nozzles. For control of woody plants, mix 0.6 to 3 L of Garlon XRT Herbicide in enough water to make 100 L of spray solution. Direct the spray solution to thoroughly wet the foliage of the target plants but not to the point of runoff. Apply after full leafout, but before autumn colouration.

When to Apply

  • For foliar applications, apply to target trees and weeds when they are actively growing
    • Trees: Apply after full leafout to actively growing trees, prior to autumn colouration.
    • Weeds: Apply to actively growing weeds, after emergence, prior to flowering.

Basal Bark and Stump Treatment

  • For selective control of woody plants, Garlon XRT Herbicide can be used in oil mixtures and applied using the streamline or stump treatment technique. Use a diluent such as mineral oil or vegetable oil. Add Garlon XRT Herbicide to the required amount of oil in the mixing tank and mix thoroughly.
  • If basal bark and stump treatment applications are required, please see Garlon RTU for additional information.

Optimizing Performance

  • For best results, apply to actively growing trees and weeds. Avoid applying to plants under stress.
  • Use higher rates when hard-to-control species such as ash, chokecherry, elm, maple (other than vine or big leaf), oaks or pine are present. If lower rates are used on hard-to-control species, resprouting may occur and retreatment may be necessary the following year.
  • Avoid applications in hot temperatures. If temperatures reach 28 C or higher, cease applications for the day.


  • There is no restriction on livestock grazing treated areas for areas applied with up to 3L/ha
  • 3 to 5 L/ha: do not graze or harvest green forage from treated area for 14 days following treatment. Note: No grazing restriction for beef livestock if less than 25% of the grazed area has been treated.
