    Q
    What's the difference between the green and red bottle of Tordon RTU Specialty Herbicide?
    A

    Tordon RTU Specialty Herbicide is now produced under Corteva, so the label has been updated to reflect this. The product has not changed, just the appearance of the label from the red Dow label to the new green Corteva label.

  • Asked by Carolyn from Layton, Ut
    07/25/2019
    Q
    We had stumps ground that had been treated with Tordon. Now everything near the area is dying. What now?
    We had treated the stumps a year ago with the Tordon.. The stumps were dead so we had them ground out. We left the mulch that was created from the grinding in the hole. The nearby shrubs are now dying and nothing will grow where the stumps were. Is there anything we can do to counteract the effect?
    A

    Tordon RTU Specialty Herbicide is a very damaging product to surrounding plants due to it’s active ingredient, Picloram.  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.  We recommend contacting the manufacturer Dow AgroSciences at 800-992-5994 for advice on what to do at this time.

  • Asked by Leroy from Topeka, Ks
    10/17/2019
    Q
    Will Tordon RTU Specialty Herbicide spread to other trees close by?
    A

    Yes, the active ingredient in Tordon RTU Specialty Herbicide is known to leach into the soil from treated roots and can remain for several years.  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
    I have a tree in the middle of my peony bed. Will Tordon RTU Specialty Herbicide bleed to my peonies?
    A

    Tordon RTU Specialty Herbicide has proven to become volatile and drift. We recommend applying Roundup to that tree. You can cut into the trunk of the tree and paint the Roundup undiluted onto the tree.

  • Asked by Carolyn from New Marshfield
    11/30/2019
    Q
    Is Tordon RTU Specialty Herbicide effective in winter?
    A

    Tordon RTU Specialty Herbicide may be applied at dormant periods but before a hard freeze (25 degrees F). Be careful not to spray so heavily that the herbicide drips off the target species. Retreatment may be necessary for plants that are missed because of dense growth. Keep in mind that this product should not be used on residential properties.

  • Asked by The from Atlanta, Georgia
    11/24/2019
    Q
    Should we be concerned that other plants in the yard may be affected if we have cut down a 25-year-old Chinese Wisteria and painted the stump with Tordon RTU?
    We are assuming it has a large root system.
    A

    Tordon RTU Specialty Herbicide can affect plants in the area where you have treated the stump if the stumps roots are in the same area as desirable plant roots.  Untreated trees/plants can occasionally be affected by root uptake of this herbicide through movement into the the topsoil or by excretion of the product from the roots of nearby treated trees. You should not apply Tordon RTU within the root zone of desirables unless such injury can be tolerated. Tordon RTU also is not labeled for use in residential areas due to its long half-life and this possibility of movement in the soil.

    We do not recommend applying Tordon RTU Specialty Herbicide or any herbicide when temperatures are below 55 degrees.

    Q
    If I want to just kill a limb of a large oak tree, can I treat the limb with the axe/injection method using Tordon?
    If I want to just kill a limb of a large oak tree, can I treat the limb with the axe/injection method?
    A

    Tordon RTU Specialty Herbicide can also injure the tree as it can travel throughout the limb into the tree itself.  It would be best to just cut any limb that you need killed/removed

  • Asked by Betty from Mankato, Mn
    07/03/2018
    Q
    I have three evergreen tree stumps that I want to get rid of using Tordon. Can I plant grass in the same area afterwards?
    A

    Tordon RTU Specialty Herbicide could be used and is best used on freshly cut stumps and ensuring the cambium area next to the bark gets thoroughly wet. We would recommend either drilling holes into the top surface of the stump or cutting off the top layer of the stump for a fresh application. Since you are treating the stump directly there should be no issue seeding in the area once the stump is killed and removed.

  • Asked by Mickey from Quitman, Tx
    11/27/2018
    Q
    Will Tordon RTU get rid of bamboo? If not, do you have a recommendation?
    I have a stand of bamboo that was recently cut to ground level.
    A

    Tordon RTU is not labeled for bamboo. Since bamboo roots go so deep, you would need to apply either a product like Roundup QuikPro at the highest rates directly to the freshly cut stumps of the bamboo after you cut it down level to the ground, or use a brush and stump killer undiluted directly on the fresh stumps. You may also want to consult with your local cooperative extension office Master Gardener for alternate suggestions.

  • Asked by Bill from Garnett, Kansas
    01/27/2017
    Q
    Will Tordon RTU kill Willow sprouts?
    A

    Tordon RTU Specialty Herbicide is not labeled to control willow sprouts, so we are not sure if it would be effective for this application. We do sell other products such as Fertilome Brush Killer and Stump Killer that can be used to treat willow sprouts. You would cut the stumps and apply the product undiluted to the fresh cuts.
