  • Asked by Dan from Harleysville, Pa
    04/10/2021
    Q
    How long does Tenacity Herbicide remain in soil, and when is it safe to plant vegetables in a previously treated area?
    I do not currently have a garden in my yard but would like to start one in the future. In the meantime, I would like to use Tenacity to control several weeds that have invaded my entire lawn. I'm wondering how long I would need to wait after application of Tenacity, both as a pre- and post-emergent, before it is safe to start growing vegetables in an area that has been previously sprayed with Tenacity.
    A

    You will need to wait one year after Tenacity is used in a given area before you can plant edible vegetation in that area.

  • Asked by John
    05/19/2021
    Q
    The first application did nothing it's been 5 days since I applied Tenacity Herbicide.
    A

    When using Tenacity, foliage of treated weeds cease growth after application, then turn white (loss of chlorophyll) and death may take up to three weeks. A repeat application is required after two to three weeks for improved postemergence weed control.

  • Asked by Tom from Dighton, Ma
    05/26/2021
    Q
    Can Tenacity get washed away if rains several consecutive days after app dries?
    A

    As long as the initial application of Tenacity Herbicide has had a chance to dry after a post emergent application it will not be washed away with rain after.  Best to apply when no rain is expected within 24 hours to be sure.

  • Asked by Carl from Texas
    06/15/2021
    Q
    I applied Tenacity when temperatures were 79 degrees and later in the day, temperatures reached 93 degrees. Will Tenacity lose its effectiveness due to the spike in temperature?
    A

    If the Tenacity Herbicide application had enough time to completely dry before the temperatures spiked to 93 degrres, there shouldn’t be any issues. It is recommended to apply Tenacity when temperatures are between 65 to 85 degrees so early morning or late evening applications may work best if temperatures above 85 degrees during the day are expected. If any yellowing or discoloration occurs, the turf should recover after a couple weeks.

  • Asked by Neville
    01/21/2023
    Q
    Application of Tenacity Herbicide after pre germinated grass seed.
    If I pre germinate my rye grass seed & plant them when roots are just starting to form, can I apply Tenacity at the same time or would I need to apply Tenacity before I plant them?
    A

    Tenacity Herbicide is best applied 2 weeks before planting/seeding a lawn or wait at least 2-3 weeks after seeding to apply.  When pre-germinating and planting in the area we would recommend waiting at least 4 weeks to apply so it is established.

    Q
    Will Tenacity affect all varieties of Poa?
    I have what I believe is Poa but am not certain of the variety (annua or other). How can I determine what I have?
    A
    Tenacity Herbicide is not labeled to control Poa Annua/Annual Bluegrass in a post emergent application, it only states that it could cause injury to it if sprayed.  It is only labeled to be used to suppress poa annua when used as a pre-emergent. We recommend to contact your Cooperative Extension Office and speak with the Master Gardener to identify the weed species you need to treat for.

    Will Tenacity work on Nutsedge growing in my Oporum ground cover?
    A
    Tenacity is a systemic preemergent labeled to treat for Yellow Nutsedge only, but not does list other types of nutsedge. We do carry Sedgehammer, a post emergent which is labeled for Purple and Yellow Nutsedge control. We recommend contacting your local Master Gardner for clarification on the effects of either of the products on you oporum ground cover.

    Q
    Is Tenacity safe for use in apple orchards in early spring?
    I have nimblewill weed in my orchard and would like to eliminate it
    A

    Tenacity is not labeled for use around anything edible so we cannot recommend it be used in an orchard.  We apologize but we do not currently have a product labeled for control of nimblewill in orchards.  However, you can click here and contact your local cooperative extension office to speak with a Master Gardner to find the name of a product and then contact us to see if we have access to that product.

  • Asked by Paul from Deer Park, Ny

    Q
    I applied Tenacity 3 weeks ago. Can I now apply Weed-Be-Gone?
    Some spots need more herbicide: Clover, Dallisgrass. Do the different herbicides react badly together?
    A

    We see no reason why you cannot apply Weed Be Gone now.  It has been 3 weeks after Tenacity Herbicide, which is plenty of time. Please take a look at the Tenacity product label to be sure that it is safe to apply to your particular grass species.

    Q
    Can you spray Tenacity and Gordon's Trimec at the same time?
    A

    It may be fine to mix both Tenacity and Gordon's Trimec together but has not been tested by the manufacturer. We recommend that you perform a jar test to an inconspicuous area first prior to a full application to confirm if you wish to use them both together.
