  • 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.

    06/27/2018
    Q
    I believe my trees are dying from being exposed to Tordon RTU Spray. Is there any way of saving them?
    A

    How long ago the application was and how much the trees were exposed to Tordon RTU Specialty Herbicide would all play a factor in whether the trees could possibly be saved. We would suggest contacting the manufacturer, Dow Agro Sciences, for specific information on how to save or reverse any exposure. Dow Agro can be reached at 317-337-3000

  • Asked by Carlos from California, Mo
    07/19/2018
    Q
    Can Tordon RTU be diluted?
    A

    Because Tordon RTU Specialty Herbicide is a ready to use herbicide it should not be diluted.  Doing so may decrease its effectiveness.

  • Asked by Pat from Macon, Mo
    10/28/2018
    Q
    Will Tordon RTU Specialty Herbicide speed up the killing process on trees that have had a ring cut around it?
    I cut a ring around large trees to kill them, but it takes a while for them to die.
    A

    Tordon RTU Specialty Herbicide can be applied via tree injection, frill or girdle treatment, or stump treatment as directed on page 3 of the product label. Frill or Girdle Treatment is the closest to what you are describing. Per the label:

    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.

    There is a complete list of woody plants controlled by this product on the label. Be sure that your target plants are included on this list and that the herbicide is applied immediately after cutting for best results.

  • Asked by Michael from Long Prairie Mn
    11/15/2018
    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 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.

    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.

  • 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).

    Q
    Will Tordon RTU work on yaupon sprouts?
    A

    Tordon RTU Specialty Herbicide is not labeled for yaupon.  Remedy Ultra Herbicide? is labeled for yaupon holly and should do a good job when used as directed on the product label. ? Hi-Yield Triclopyr Ester Ultra contains the same active ingredient at a lower cost if smaller areas need treatment.

  • 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.

    Q
    Will Tordon RTU kill Schefflera tree stumps?
    A

    Tordon RTU Specialty Herbicide is not labeled for Schefflera trees.  Schefflera actinophylla is very invasive and hard to kill.  We do not carry products labeled specifically for it.  An article from the US Military’s Integrated Natural Resources Management Plan states that Garlon 4 has been used in some instances and proved to be effective, although it is not labeled for it.  We would recommend speaking with your local master gardner for more recommendations.

  • 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 Deborah from South Carolina
    12/03/2019
    Q
    Would Tordon RTU Specialty Herbicide kill through the cut of a woody stem on Wisteria?
    A

    Tordon RTU Specialty Herbicide is not labeled to control Wisteria, so we do not recommend it for this application. Keep in mind, too, that Tordon is not approved for use on residential properties at all. You could use a brush killer such as Crossbow or Fertilome Brush and Stump Killer to control wisteria vines.
