  • Asked by Randall from Wautoma, Wisconsin
    05/30/2019
    Q
    Can you mix Tordon in a sprayer to kill barberry?
    How much Tordon per gallon of water?
    A

    Tordon RTU is a Ready To Use herbicide and should not be diluted with water. This product is not labeled to control barberry, and it also should not be used in residential areas. The active ingredient in Tordon RTU has an extremely long half-life and, therefore, it can remain active in the area for years after application. To control a shrub like barberry, you would probably need to cut the shrubs down and treat the fresh cuts with a brush killer such as Fertilome Brush and Stump Killer directly to the fresh cuts.

  • Asked by Pamela from Hartford City
    10/03/2017
    Q
    Do I use Tordon undiluted, and will it work on hybrid poplar stumps and sprouts?
    A

    Tordon RTU Specialty Herbicide is not labeled to control sprouting on poplar. We would recommend an herbicide containing Triclopyr to treat the cut stumps, such as Remedy Ultra (needs to be diluted with an oil) or Fertilome Brush Killer and Stump Killer (may be applied undiluted).

  • Asked by Marilyn from Derry
    10/17/2015
    Q
    Will Tordon RTU kill a cedar stump and how long will it take?
    A

    Yes, Tordon RTU Specialty Herbicide is effective in killing over 20 different woody species, including cedar, and preventing resprouting of those cut trees. Unfortunately, it is hard to say for sure how long it will take because the kill time is due in part to many environmental factors. If you need further assistance you may contact Dow AgroSciences at 800-992-5994.

  • Asked by Javier from Houston
    05/12/2019
    Q
    Can you put Tordon RTU Specialty Herbicide around the base of a small tree like a drench to kill it, without cutting it?
    A

    Tordon RTU Specialty Herbicide is not labeled to be poured around the base of a tree as a drench. This product can be applied three ways; Tree Injection Treatment, Frill or Girdle Treatment & Stump Treatment. 

    Tree Injection Treatment: Use 1 milliliter of undiluted Tordon RTU solution through the bark
    completely around the tree trunk at intervals of 2 to 3 inches between
    edges of the injector wounds. Make injections near ground level when
    using the tree injector or 2 to 4 feet above the ground when using a
    Hypohatchet Injector or similar device. Treatments can be made in any
    season. Maples should not be treated during the spring sap flow. With
    some difficult to control species such as dogwood, hickory, sugar maple,
    bigleaf maple, tanoak, and some firs, application to a continuous cut
    rather than to spaced cuts may be more uniformly effective. 

    Frill or Girdle Treatment: Make a single hack girdle or "frill" of overlapping ax cuts through the bark
    completely around the tree as close to the ground as feasible. Spray or
    paint the injured surface with undiluted Tordon RTU, using enough volume
    to wet treated areas.

    Stump Treatment: Spray or paint the cut surfaces of freshly cut stumps and stubs with
    undiluted Tordon RTU. The cambium area next to the bark is the most
    vital area to wet.

  • Asked by Linda from Apache Junction, Az
    02/13/2018
    Q
    Will Tordon RTU Specialty Herbicide work on cactus, particularly cholla and prickly pear?
    If not, what do you recommend?
    A

    Tordon RTU Specialty Herbicide is not labeled specifically to control prickly pear or other cacti, but some articles recommend this active ingredient to aid in control. One very difficult part of controlling this plant is that all debris must be removed from the area to prevent resprouting. Unfortunately, we do not have any herbicides currently labeled to control cactus. This Field Guide from the USDA discusses control methods for prickly pear cactus. Another active ingredient mentioned is Fluroxypyr, which we do have in the product E-2 Herbicide. We recommend consulting your local Cooperative Extension office for assistance. Since this is a heavily invasive species of importance, most local offices will want to know where the plant is being found.

    Q
    Can Tordon be used on palm tree stumps?
    If so, is there a safe radius one should keep out of as far as neighboring trees and shrubs close to stump being treated?
    A
    Since Palm trees are not on the product label and to make sure Tordon will treat palm tree stumps, please contact the manufacturer Dow Agrosciences at 800-992-5994.

    Q
    Can Tordon RTU be used for buckthorn?
    A

    Tordon RTU Specialty Herbicide is not labeled for buckthorn.  Crossbow or RoundUp can be used to kill cut stumps.  Apply immediately after cutting the stump to prevent resprouting.  There is a great article here from the Dept of Natural Resources in Minnesota that may be helpful.

  • Asked by Sheri from Colville
    05/25/2018
    Q
    What is the best fertilizer to use after Tordon RTU is applied to my lawn? I live in N.E. Washington state.
    A

    The best fertilizer to use will depend on the specific needs of your lawn and soil.  We recommend using a soil analysis test kit or taking a sample of your soil to your local cooperative extension so your soil can be analyzed to determine what nutrients your soil is lacking. The healthiest, hardiest lawns are fertilized 2-4 times per year, fall, summer, early spring and late spring

    We do offer a soil test kit here.

  • Asked by Bill from Schuylkill Haven, Pa
    08/16/2019
    Q
    Can I use Tordon RTU on a stump that was cut 2 months ago if I drill holes in it? Can I plant grass in the area afterwards?
    A

    Tordon RTU Specialty Herbicide is best applied to fresh cut stumps, so you can either make a fresh cut or you can drill new holes and then apply.  Since the active ingredient in Tordon RTU is known to leach into the soil from treated roots and can remain for several years you would need to completely replace any soil in the area before planting anything else.  Untreated trees/plants can occasionally be affected by root uptake of herbicide through movement into the the topsoil or by excretion of the product from the roots of nearby treated trees. Do not apply Tordon RTU within the root zone of desireables unless such injury can be tolerated.

  • Asked by Jeannette from Pointe-du-chene
    10/18/2019
    Q
    Will Tordon RTU kill a Norwegian maple stem and root system?
    A

    Tordon RTU Specialty Herbicide is labeled to control maples in general, though we are not sure if it has been tested specifically on Norwegian maples. Keep in mind that Tordon RTU should not be used on residential properties at all: this product has a very long half-life and can affect other plants near the treatment area for years after application. Please let us know if you need a recommendation for an alternate product.
