  • 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 Brad from Cameron
    05/06/2021
    Q
    Can you apply Tenacity Herbicideafter using 2-4,D herbicide?
    I have applied 2-4 d for weeds and would like to use Tenacity as a preemergence for crabgrass
    A

    Tenacity Herbicide can be used on a lawn that 2,4 d or other herbicides have been applied to safely as long as you follow label instructions and apply it evenly. Tenacity will only last about 30 days as a pre emergent compared to other pre emergents on the market that will last 3-4 months. Tenacity is mostly used as a pre emergent in the spring or fall when customers are over seeding their lawns with a cool season grass to fill in bare spots, as its one of the only products that can be used at this time without harming the seed. If you are not seeding, you may want to consider a longer lasting pre emergent or one that covers a wider range of weeds than the Tenacity does, like the Dimension 2EW or Pendulum 2G for instance. If using Tenacity as a pre for crabgrass, you want to put it down at or just prior to your soil temperatures reaching 55 degrees in order to be effective. If soil temps have already progressed past 55 degrees your pre emergent will not do much to stop the weeds.

  • Asked by Geoffrey from Liverpool, New York
    08/18/2021
    Q
    How soon can apply Tenacity Herbicide after/between rainfall?
    I live in upstate NY (Liverpool). We've gotten a bunch of rain Lately. I installed a roll of turf 3 weeks ago and it has established itself well. I unfortunately there is a about a 1-foot square section of crabgrass immediately next to it. My questions: How soon can apply after/between rainfall events? Can I apply tenacity to this area where newish turf and crabgrass meet? I also have pathed a few spots around the awn where I placed soil and seed. I have new grass that appears ready for mowing and some areas that have just started sprouting. I plan to avoid these patches until they are mowed a couple times. Any advice about these would be greatly appreciated.
    A

    As stated on the product label of Tenacity, this product should be applied when there is no rain in the forecast for at least 48 hours. "If rainfall (0.15 inches) has not occurred within 10 days after preemergence application, activate with 0.15 inches of irrigation." This product can be applied to established, tolerable turf types.

    Please be sure to review the product label for more information and complete application instructions.

  • Asked by Anna from Canada
    10/08/2022
    Q
    Can Tenacity be applied if the grass is slightly wet from cooler temps and dew or does it need to be completely dry? This is for a second application to control bentgrass (Zone 5b) and the day/evening temps are much cooler.
    A

    It would be best to wait to apply Tenacity Herbicide until the grass has completely dried before the application. Be sure to mix in a Non Ionic Surfactant when doing post emergent applications.

  • Asked by Neville

    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.

  • Asked by Jeffrey from Trumbull
    05/10/2015
    Q
    Will Tenacity damage Poa trivialis lawngrass?
    I have Poa Triv in shady areas and need to get rid of invasive creeping bent in my lawn.
    A
    The product label for Tenacity does not specify whether it would harm poa trivialis. Both bentgrass and poa annua may be sensitive to Tenacity, while Kentucky Bluegrass is listed as tolerant. Certainty Herbicide is labeled to control poa trivialis, but we are not certain if it would harm the bentgrass. The best option for you is to spot treat the rough bluegrass with RoundUp QuickPro and then reseed with the desirable turfgrass.

  • Asked by Rod from La Habra Ca
    10/30/2016
    Q
    If I only used 1 tsp of Tenacity Herbicide per gallon of water and not in 2 gallons of water, should I repeat application or go ahead and reseed the area?
    I purchased a bottle of tenacity from you a few months back. I recently treated areas of tall fescue that have turned ghost white (whitening was expected) a week + later I realized I messed up and mixed only 1 gallon per tsp/1000 sq feet + nis . The label calls for 2 gallons of water per tsp. Please let me know if you have any feedback of whether I should wait it out or prepare to reseed the affected areas? Thanks
    A

    Since Tenacity is an effective herbicide for weed control prior to or during seeding of certain turfgrasses during turf renovation and the water is only acting as the carrier for the solution to get into the weeds, you should be ok to reseed if you are happy with the results. For post emergent applications, you will need to wait for the turf to be established after 2 mowings to reapply.

  • 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.

    05/07/2017
    Q
    How many ounces of Tenacity Herbicide should I put in a 26 gallon boom sprayer?
    How many ounces of tenacity and surfactant are needed in a 26 gallon boom sprayer for general lawn/grass weed maintenance? Ive read for tenacity, 1 teaspoon per 2 gallons of water but also 4-8 oz per acre in at least 30 gallons of water. How much surfactant should be included?
    A

    When using Tenacity Herbicide, the amount of water is not what is important; the right amount of product is. The rate for 1000 square feet is 1 teaspoon. The will mix in 1-2 gallons of water. Please let me know how much area you are treating to give you the best rate.

    The rate of the surfactant is 1-2 teaspoons per gallon of water. For 26 gallons of water, the rate of surfactant is 26-52 fl oz.
