    Q
    Would it be okay to use one application of Tenacity Herbicide for a large area, do a 2nd application 2 weeks later, and then use a slit seeder?
    I already have existing centipede grass but want to overseed with seed slitter but afraid my order of application may mess up germination.
    A

    You can apply Tenacity anytime before seeding up to the same time that you seed. If you are applying Tenacity as a post-emergent herbicide, then it is usually best to do that application first and wait for the treated plants to die so you can remove any excess dead plant matter before you overseed the lawn. Tenacity will not interfere with seed germination of turfgrasses listed as tolerant on the product label.

    Q
    Can Tenacity be sprayed up to and around young fruit trees?
    A

    Tenacity Herbicide cannot be applied around edible vegetation. When applying the product to your lawn, you would want to be sure to avoid over-spray or drift of spray applications onto the fruit trees, and avoid spraying within the drip line of any edible trees.

  • Asked by Glenn from Setauket, Ny
    07/25/2019
    Q
    Are all pump sprayers alike?
    I have a couple sprayers. 1 gal and 4 gal. They also have a variety of tips. Are all sprayers alike as far as the amount of Tenacity that will be put down? Even if you go at an even pace, how do you know you are putting the right amount down? If sprayers are different, how do you know what pace to go at? It seems that one of my sprayers is more "powerful" then the other, so I'm not sure how to know how much is too much, or not enough. Thanks
    A

    If you have multiple sprayers, then the best thing for you to do is to calibrate your equipment using just water over a small area. For example, you can mark off an area that is 1000 sq ft (20 x 50 feet), fill your tank with 1-2 gallons of water, and then walk at your normal pace and see how much water you used to cover that area. It is most important that you use the correct amount of herbicide for the size area you are treating and think of the water as the carrier, rather than insisting on a specific amount of product per gallon of water. If you take this time to calibrate your sprayer once, then you will know how much water you use for the area going forward. Using a spray indicator dye is also a great tool so that you apply herbicides evenly over your yard.

  • Asked by Douglas from Nashville, Tennessee

    Q
    Can I overseed Bermuda at some point after using Tenacity?
    https://www.domyown.com/tenacity-herbicide-p-1877.htmlDormant. With the fall here now I'm ready however my question regards over-seeding.
    A

    Since Tenacity Herbicide can be used only on fully dormant Bermudagrass, there is not a time when you would be overseeding and using Tenacity at the same time. You would overseed with Bermuda when the turf is actively growing in spring or summer, if needed at all. So if you applied Tenacity on dormant Bermuda, then it would be long gone by the time the turf is completely green and any seeding would be fone. If you would like to tell us more about the weeds you are targeting, then we can recommend alternate products for your needs.

  • Asked by Rick from Louisville, Ky

    Q
    I'm confused whether or not it will hurt new Kentucky Bluegrass seed?
    I've read the label but it say's it hurts Fescue's when seeding but it also says it suppresses Bluegrass, Annual Poa annua. I need this cleared up as I'm about to seed. I've already put 1 app of Tenacity down.
    A
    Kentucky Bluegrass (Poa pratensis) is different than regular Bluegrass (poa annua). It is true that Tenacity may reduce density of fine fescue seedings. Tenacity can be used on grass seed blends that contain less than 20% by weight of hard or fine fescue. It will not harm your Kentucky Bluegrass seeding. If you need more specific information on a turfgrass not mentioned on the product label you can reach the manufacturer at 866-796-4368.

    Q
    Can Dimension 2EW be mixed with Tenacity?
    I'm planning to spray in fall to remove weeds and grassy. So, I'm wondering if Tenacity can mix with Dimension? It would be okay?
    A

    The Tenacity product label does state that it can be mixed with pre-emergence products to provide season long control.  Dimension's product label does also state that it can be.  Please refer to both for complete instructions and you may need to perform a compatibility test before treatment.

    Q
    When do I apply Tenacity Herbicide for bent grass?
    I have bent grass that is now brown. Is it dormant? When is "just before dormancy?"
    A

    If you are trying to apply Tenacity Herbicide to control bentgrass, per the product label:

    "Apply Tenacity at 5 fl. oz. per acre in at least 30 gallons of water per acre at two to three week interval for up to three applications. Apply with a NIS surfactant. Bentgrass control may be more effective in the late summer/early fall just prior to onset of renewed bentgrass growth, than spring/early summer applications."

    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
    What is best herbicide to control weed called nimblewill in mixed lawn of Zoysia & St. Augustine Grass, FL?
    We are in mid Florida on East Coast above Daytona Beach and below St Augustine in a city called Palm Coast, Fl.
    A

    Tenacity Herbicide is a great option for post emergent control of nimblewill. However it is not safe for use in Zoysiagrass and is only for use on St Augustine when used in sod farm. You could use the Tenacity as a spot treatment only for nimblewill as we would not recommend using it as a broadcast spray on your lawn.

    Q
    Tenacity with overseeding timing
    I know you can put down tenacity at time of overseeding, but if you miss it do you have to wait 4-6 weeks? Or could you do it a week after overseeding for example? I was thinking if it doesn't affect germination that you should be put it down whenever you wanted regardless of when you overseeded, but don't know for sure. Thanks.
    A

    Tenacity Herbicide is best applied right at the time of seeding or close to for best results. It can be applied later if needed for the turfgrasses listed on the label with the following precaution: Avoid spraying on newly germinated turfgrass plants. Wait until the newly germinated turf has been mowed two times or four weeks after emergence (whichever is longer) before making a postemergence application.

  • Asked by Claudia from Ness City, Kansas
    07/08/2014
    Q
    I bought Tenacity to kill some small spurge in Buffalograss. What strength should I use in a one gallon spray
    It doesn't seem to be killing it. Should I use it stronger or more often? At first I used it 1/2 tsp in 1 gallon with 1/2 tsp surfactant
    A
    Tenacity Herbicide does not list spurge as a weed that it controls on the product label so that would be why it is not working for this weed.  You would have better success using a product that specifically lists spurge on the label such as the Speedzone Southern.

  • Asked by John from Great Neck, Ny
    10/27/2015
    Q
    What are the application instructions for Tenacity on fine fescue turf?
    My lawn is fine fescue, and I overseed every spring and sometimes in fall. The label states not to use Tenacity at the same time as seeding fine fescue. Thus, what would be the best strategy to use Tenacity on my lawn for pre and post-emergent purpose? Should I look for an alternative product?
    A

    Per the Tenacity label, you will not exceed 5 fl. oz. of product per acre for fine fescue. This is just the max amount that should be used per year and per acre. The rate that should be used is you will need to mix 0.5 tsp of Tenacity and 1.5 tsp of surfactant to one gallon of water covering 1,000 sq ft. Also, Tenacity should NOT be applied at the time you are putting down new seeds or overseeding. This will likely inhibit their growth. You will want to wait until the lawn has been established before applying this product for pre-emergent control. This is generally after three mowings. There are no restrictions for Tenacity with regards to post-emergent control of weeds.
