    Q
    Can you spray tenacity over dead grass
    Haven't watered the grass. Grass is dead. The summer heat has killed my lawn. I have annul bluegrass in with the dead grass. Will this help with killing the annul bluegrass if I spray tenacity over the dead grass?
    A
    Tenacity Herbicide will not control annual bluegrass so whether the lawn was currently alive or dead wouldn't make a difference in this case. If the lawn is already dead, you can spot spray the annual bluegrass with roundup. Typically, annual bluegrass cannot withstand high heat temps, so if the heat this summer has been high enough to kill or heavily damage your lawn, it should have also done the same to the annual bluegrass. If you plan to reseed your lawn this fall, then you can try using the Tenacity as a pre emergent during seeding, however it is only labeled for poa annua suppression when used as a pre, and there are other herbicides that would be better suited to preventing it from coming back. However the herbicides that do this the most effectively are also ones that would prevent your new grass from coming up, so you could not seed and use a better suited pre for poa annua in the same season.

    Q
    Tenacity for crabgrass in a very thick Centipede grass lawn.
    I've got patches of crabgrass in a thick Centipede lawn. Can I spray Tenacity on it mid-summer even if it's down deep in the centipede?
    A

    Tenacity Herbicide can be applied in the summer and works best on crabgrass that has just emerged up to the 4 tiller stage.  Keep in mind that the best temperature range to apply most herbicides, including Tenacity, is between 65-85 degrees. We recommend early morning or late evening applications to avoid damage to your lawn.

  • Asked by James from San Antonio, Tx
    08/21/2021
    Q
    Is Tenacity effective against Sandburs? If so, when is the best time to treat?
    A

    Tenacity Herbicide is labeled for post emergent control of actively growing lawn burweed (spurweed, stickerweed, sandbur, sanbur, and sandspur) but will not offer any pre emergent control to prevent sandbur from germinating. When using Tenacity for post emergent control of weeds, a Non Ionic Surfactant is needed.

  • Asked by Edison
    12/15/2021
    Q
    Will Tenacity Herbicide kill woodsorrel in St. Augustine lawns?
    A

    Tenacity Herbicide cannot be used on residential St Augustine lawns and will not eliminate woodsorrel.

    To control woodsorrel (also known as oxalis) in a St Augustine lawn, you could use a product like Hi Yield Atrazine, or Fertilome Weed Free Zone. 

    • Please note, Fertilome Weed Free Zone is not recommend to be used on Floratam or Bitterblue varieties of St Augustine unless discoloration and temporary injury can be tolerated. Other species of St Augustine would be safe if used at labeled rates.  

    It is recommended to apply a pre emergent like Pendulum 2G in Fall and Spring. (55 degrees in the Spring / Between 70 and 55 degrees in the Fall). Pre emergents prevent weeds from germinating which will help cut down on the amount of post emergents needed during growing seasons.

  • 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 Lawrence from Wilmington, Il.
    10/01/2019
    Q
    Why do you not want to use a hose end sprayer while applying Tenacity Herbicide?
    A

    It is not recommended to use a hose-end sprayer to treat your lawn with Tenacity Herbicide or any other herbicide. The problem with using hose-end sprayers is that they are not very accurate, and you can wind up dispensing more or less product than recommended per area. This can lead to less than desirable results.

    Q
    Tenacity use on dormant near semi-dormant Bermuda grass
    After applying Tenacity to my dormant near semi-dormant Bermuda grass, It seems like the Tenacity killed certain large areas of grass. What is your recommendation to fix this issue? Will Bermuda grass overgrow that area or should I seed?
    A

    If the Tenacity Herbicide is used on semi-dormant grass, it may harm the turf as you have seen since it is only labeled to be used on fully dormant bermudagrass. You can wait it out to see if the bermuda grows back or you would wait at least 3-4 months to reseed.. The label does not give a specific time frame of reseeding with bermuda when Tenacity is used but since it is shorter-acting than other pre-emergents so as long as the residual of Tenacity is gone, you can reseed/sod.

  • Asked by Ray from New Jersey.
    04/07/2020
    Q
    How much longer before yellow colored patches turn green after using Tenacity Herbicide?
    I applied Tenacity as a preemergent the first week of March. 2 weeks later there are large straw colored patches. To date surrounding areas are green and patches are still there.
    A

    It depends on what type of turfgrass Tenacity Herbicide was applied to. If the grass is labeled tolerant to the product then it will bounce back as long as it's a healthy lawn. We would recommend to contact your county extension office to identify if it's a disease.

    Q
    Will Tenacity Herbicide work on weeds that are in rocks, not grass?
    I have weeds in rocks, have sprayed, but reading how it should be used for weeds in grass.
    A
    Tenacity Herbicide

     is only labeled to be used in turfgrasses for weed control.  If there are no desirable plants in the area where you have rock areas, it should not be an issue to just spot treat the weeds there directly, but usually something like RoundUp QuikPro is more used in this case.

  • Asked by Pratikkumar from Englishtown
    08/27/2020
    Q
    When should I use Tenacity as a pre-emergent in Central NJ?
    We recently ordered and used two days back as a post emergent. Need to know when should we use it as a preemergent in the spring i.e. expecting a temperature range of the day and approximate time in terms of the month/week of the month in the response.
    A

    Tenacity would be applied as a pre-emergent in spring when soil temperatures are about 55 degrees. This will vary depending on your location, so we advise to reach out to your local extension office for advise on perfect timing in your area. Keep in mind that Tenacity only last about 30 days in the soil when applied as a pre-emergent. So if you are not overseeding your turfgrass, then we recommend selecting a different product such as Barricade 4L.
