  • Asked by Tim from Va
    08/02/2019
    Q
    Can I have a full list of weeds that Tenacity will control?
    Can Sedgehammer be used mixed/used at the same time as Tenacity?
    A

    You can find a full list of weeds Tenacity Herbicide targets here: Tenacity Product Label. There should not be any issues using Tenacity Herbicide and Sedgehammer Herbicide at the same time as long as the turf is established and not under other significant stress. Tenacity Herbicide states the following in reference to tank mixing. We always recommend doing a small tank mix test before application. 

    "Tenacity has been tested in tank mixtures with Barricade 65WG Herbicide (prodiamine), Vanquish® (dicamba), Turflon® ester (riclopyr), Spotlight™ (fluroxypyr), Quicksilver™ (carfentrazone), Basagran® (bentazon), Princep® (simazine), and AAtrex® (atrazine) for safety and efficacy on turfgrasses. Tenacity must be applied at reduced rates (4 fl. oz./A or less) if tank mixed with atrazine, bentazon or simazine. Other tank mixture partners may be safe but have not been tested. Turf managers wanting to tank mix Tenacity with other herbicides should test on a small basis for compatibility, safety and efficacy before treating large areas. See product labels for directions and precautions"

    Is Tenacity good for treating quackgrass? This perennial plant is a nuisance here in New England.

    Q
    How soon after a pre-emergent appication of Tenacity can I apply a post-emergent spray of Tenacity?
    A

    After further information from the manufacturer they have verified that to making a pre-remergent application with Tenacity you will need to apply a post emergent application once you detect germination of the weed itself. Syngenta recommends to apply no more than 3 application per year.

    Q
    How long after Tenacity application can I seed with an annual rye?
    I see instruction for perennial rye but not annual. I have decided to switch to Bermuda next year so a temporary rye lawn would be best for me this winter but I've already treated with Tenacity twice. How long until I can seed annual Rye? Or not at all?
    A

    When using Tenacity Herbicide there should be no issue with planting annual rye seed after using it. Per the product label you would want to apply either at seeding or close to it for the best performance.

    Q
    Can I now do my second round of Tenacity Herbicide on new grass?
    I got one round of tenacity on my lawn then i aerated & reseeded 3 weeks ago. I fixed some large bare spots as well. I have new grass growing, but I see more weeds and clover and Crabgrass coming back. Can I now do my second round of Tenacity on this new grass. I'm starting the win the battle looks like, but Crabgrass is still hanging in there on about 30 % of total lawn.
    A

    If you have already seeded, then you do not want to apply Tenacity Herbicide to the newly seeded turf until is has been mowed two times or four weeks after emergence (whichever is longer) before making a postemergence application.

  • Asked by Cole from Hartford, Ct

    Q
    Can I use Tenacity in CT now?
    Here in Connecticut, can I apply Tenacity while the grass is still dormant and temps are in the 50's?
    A

    Tenacity Herbicide can be used if weeds are actively growing for post emergent control as long as the soil temperature is 55 degrees Fahrenheit. This product can also be used for pre-emergent control right now once the soil temperature reaches 55 degrees Fahrenheit. Be sure to water the product in at least 1/2 inch after a pre-emergent application to ensure the product gets down into the soil.
