    Q
    Should I aerate prior to applying Tenacity?
    I am planning on aerating my lawn.
    A

    If you plan on aerating it is best to aerate prior to an application of Tenacity. This is especially important for pre-emergent weed control.

    Q
    Can aerate after using Tenacity Herbicide?
    I'm trying to build a schedule but I have a hard time planning it out. I plan to core aerate my yard now and then after winter and again in the fall and overseed. Does it matter when I aerate after applying this stuff or do I need to wait until all the weed grasses are gone? I assume that the weeds being covered by this will still die even if they end up buried under the cores.
    A

    SInce you can use Tenacity Herbicide either prior to or during seeding of certain turfgrasses you could either aerate before or after using the product and it would still work. There is nothing on the product label stating that there is a certain time to do aerating.

    Q
    When can the lawn be aerated and overseeded after applying Tenacity?
    A

    When spot treating with Tenacity Herbicide, you can aerate any time after that without any issues. If the plan is to make a broadcast application, we recommend to aerate before the treatment is applied.

  • Asked by Douglas from Nashville
    08/05/2019
    Q
    Should I use Tenacity before or after aerating and overseeding?
    I'm starting to think about using my tenacity in September however I want to aerate and overseed my yard either before or after. What are your recommendations as to a timeline before after
    A

    If you are using Tenacity Herbicide as a pre-emergent herbicide, then you should aerate first and then apply Tenacity at the same time as seeding or just before. Do not wait until the new grass has started to come up before using Tenacity. If using Tenacity as a post-emergent, then you can apply anytime before seeding, but keep in mind that it may take a couple weeks to kill the target plants, so you would want to wait for those plants to die before aerating and reseeding.

    Q
    After a hot summer and appling tenacity late summer how and when do I get rid of all the dead white matter ?
    Should I de-thatch the lawn before over seeding to clear out the dead weeds and white remnants ?
    A

    You do not have to remove dead plant matter after using Tenacity Herbicide. However if you plan to overseed, then it is a good idea to rake out dead plants since you may need to dethatch or aerate before putting down your new seed.

  • Asked by Jane from Albany, Ny

    Q
    Should dead/dying crabgrass be pulled up before Sept. overseeding after using Tenacity Herbicide?
    Crabgrass has taken over front lawn. Applied Tenacity in early August and crabgrass white/brown and dying 2 1/2 - 3 weeks later. Now I want to do a fall overseed. Do the massive areas of dead crabgrass (and some nutsedge) all have to be pulled up before roughing up, spreading top soil and reseeding? Need to reseed soon, but the crabgrass won't have withered and died in time. (in Mid-state NY).
    A

    When using Tenacity Herbicide you should remove the thatch layer before reseeding, and it is best to aerate prior to the application as well. You want to be sure that the new seed has the best chance to come in contact with the soil.

  • Asked by Dustin from Ceresco
    06/24/2022
    Q
    Can I combine Q4 and tenacity as a post emergent?
    If so, what's the rate for application
    A

    Tenacity Herbicide should not be tank mixed with Q4. Q4 does not require the addition of a surfactant for post emergent applications while Tenacity does. You also only spot treat with Tenacity for post emergent control but can broadcast with the Q4.

  • Asked by Ruth from Cullman Alabama

    Q
    Will Tenacity Herbicide kill weeds while my grass is dormant without injuring my lawn.
    A

    Tenacity Herbicide can be applied to dormant bermudagrass only without injuring the bermudagrass. However, a better product would be Negate 37WG. 

    Negate 37WG can be used on dormant or growing turf for listed weeds as directed on the product label.

    Q
    Should I use a surfactant when applying Tenacity Herbicide to a newly seeded lawn?
    Trying to restore my lawn and aerate/seed this past Saturday 9/3/2016. Waiting for my order of Tenacity and Surfactant to arrive sometimes this week. Should I use both products and apply to the new lawn even though it's a week after seeding? Also should I use surfactant with it for pre-emergence or is that only for post? Thanks in advance!
    A

    It is safe to apply Tenacity Herbicide at or near seeding for most types of turfgrass for pre-emergent control. You should avoid spraying Tenacity on newly germinated turfgrass plants. Please refer to the product label for complete application instructions. You would only need to use a surfactant when applying Tenacity for post-emergent weed control.
