    Q
    Can you mix insecticide with Tenacity?
    A

    It is not recommended to mix certain insecticides with Tenacity Herbicide.  You should wait to apply organophosphate or carbamate insecticides 7 days after treating with Tenacity Herbicide to avoid potential turf injury. Other active ingredients would be fine to use at the same time.

    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.

    Q
    When do you spray Tenacity Herbicide?
    A

    Tenacity Herbicide should be applied before soil temperatures reach 55 degrees if using as a pre-emergent. If using as a post-emergent you would apply when the target weeds are actively growing and healthy. You can check with your local cooperative extension office Master Gardener for specific timing in your area.

    Q
    What is the ratio of Tenacity for established Kentucky blue and ryegrass lawn?
    I have a well established lawn comprised of mostly ryegrass and Kentucky blue that is slowly succumbing to spreading bent grass. I am struggling to confirm ratio of Tenactiy to surfactant to water for proper post emergent application. Can you please provide a ratio based on tank mixing 30 gallons at a time?
    A

    The amount of Tenacity Herbicide that is used is based on the amount of area you are treating. With herbicides, the amount of water is not as important as the amount of water that is being used. The rate we would recommend using is 5 fl oz to cover an acre. This can be mixed in 25-30 gallons of water to cover an acre.

    Q
    Can you put to much Tenacity Herbicide down when sowing new seed?
    I sowed some new seed about 2 months ago. Tenacity worked great and the weeds that came up died in a few weeks. When I applied Tenacity I did go over the area once or three times. The grass is still there but there is some grass that looks like it died off.
    A

    Yes, it is possible for Tenacity Herbicide to inhibit growth of new seedings if over applied.

  • Asked by Dc from Greenwood, La
    06/28/2019
    Q
    What is the differance between all of these herbicides like Tenacity Herbicide and Round Up?
    A

    Roundup products contain glyphosate which is non selective so kills pretty much anything that it is applied to.  Selective herbicides like Tenacity Herbicide only kills those weeds that are listed on the product label and are generally safe for use on turfgrass.

  • Asked by Michael
    05/16/2019
    Q
    When can I overseed when using Tenacity Herbicide?
    A

    Tenacity Herbicide is one of the few products that can be applied at seeding, prior to seeding, or just after seeding of new grasses to help prevent and control weeds at the same time. Be sure to check the label for any restrictions to certain turf types as Fine Fescue is more sensitive than other species when using Tenacity at seeding. Be sure to use a Non Ionic Surfactant with the Tenacity when applying for best results.

  • 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.

    09/26/2017
    Q
    Do I need to wait for the last application to reseed after using Tenacity Herbicide?
    I am applying my first round of tenacity and plan on reseeding. I anticipate I will need a re-application in 2-3wks per bottle instructions. Do I need to wait until my finial application to reseed as the label says to wait two mows or 4wks before applying to newly germinated seeds?
    A

    Per the label of Tenacity Herbicide, this product can be applied at the same time of seed, except fine fescue. It is recommended that you mow at least two days before and/or two days after.

    Q
    Can Tenacity Herbicide be used to control Goosegrass on Bermuda?
    A

    Tenacity can be used on dormant bermudagrass for goosegrass. If the product is used on semi-dormant grass, it may harm the turf by turning it white. When treating for goosegrass with Tenacity, it is best used for post-emergent control.

    04/28/2016
    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.
