    Q
    Can I apply Tenacity to some of my Bermuda yards now that they are about to go dormant to help further kills some spurge and clover, oxalis and further help with next spring weeds and grasses?
    Can I apply again in spring?
    A

    The product label states that Bermuda grass is sensitive to Tenacity. It can be used on dormant bermudagrass for goosegrass. If the product is used on semi-dormant grass, it may harm the turf by turning it white.

  • Asked by Greg from Green Bay, Wi
    07/18/2018
    Q
    To kill extensive bentgrass, is it best to apply the first application of Tenacity as soon as the grass begins to come back or wait until the grass is completely back and fully green?
    All bentgrass is dormant now. Wisconsin climate. Looking to apply late summer/early fall.
    A

    Your first application of Tenacity Herbicide in the fall to control bentgrass will be most effective just before the onset of new growth. You can then apply at 2-3 week intervals. You do not want to wait for it to be fully re-established to start treatment.

  • Asked by Mark from Palo Alto, Ca
    09/14/2018
    Q
    What is the best time to use Tenacity on nimblewill?
    Have applied Tenacity once three weeks ago, but if September - February is nimblewill dormancy, should the remaining two or three applications wait until say March 2019?
    A

    Per the label for Tenacity Herbicide, it is best to treat nimblewill with 2-3 applications which are 2-3 weeks apart. If the nimblewill is still green, then you can go ahead and retreat now. If it is already dormant, then it would be best to wait until it is green again to treat with herbicides.

  • Asked by Greg from Alvaton, Ky

    Q
    Can Poa Contstictor be mixed with Tenacity?
    Tenacity takes care of all my grassy weed problems. However, it does not offer eradication of Poa Annua; can the two chemicals be mixed together, therefore solving all grassy weed problems with one application? I would also use a nonionic surfactant.
    A

    The label for Poa Constrictor does not mention anything about tank mixing with another herbicide such as Tenacity Herbicide.  Per the Tenacity label: Other tank mixture partners may be safe but have not been tested. Turf managers wanting to tank mix Tenacity with other herbicides should test on a small basis for compatibility, safety and efficacy before treating large areas.

    We would recommend doing a compatibility test before treating.

  • Asked by Sd` from Millstadt, Il
    05/05/2019
    Q
    How long after applying Trimec do I need to wait to use Tenacity?
    A

    Your timing is really going to depend on a lot of factors, such as the weeds you are targeting and if/when you are seeding. We would exercise caution if you are applying multiple herbicides at the same time, especially since Trimec is already a blend of 3 active ingredients. Mixing Trimec and Tenacity would be used only as a spot spray, and we would still do a small jar test before mixing a tank of these as well as testing an inconspicuous area of the lawn for tolerance first. You should only use Tenacity as a broadcast pre-emergent application if you are renovating or overseeding the lawn, and most Trimec products require you to wait 2-4 weeks after application before you can reseed. Please let us know if you have additional questions about your application.
