  • Asked by Larry from Cowlesville, Ny

    Q
    For spot spraying crabgrass with Tenacity Herbicide, can a dye be used?
    A

     

    Tenacity Herbicide would be a great option for you to control crabgrass, and yes it is advised to use a dye like Turf Mark Blue with it so you can make sure to not overlap if you plan to do a broadcast application on the property.

  • Asked by Nike from Michigan
    09/05/2018
    Q
    Can Tenacity Herbicide be used to treat bentgrass on new cool-season grasses I planted about 3 weeks ago?
    A

    You will want to wait until the newly germinated turf has been mowed two times or four weeks after emergence (whichever is longer) before making a postemergence application with Tenacity Herbicide to the new cool season turf. For the most effective Bentgrass control, you will need to reapply Tenacity Herbicide at two to three-week intervals for up to three applications. Be sure to apply with a NIS surfactant. Making applications in late summer/early fall just before new growth is very effective in controlling bentgrass.

  • Asked by Henry from Schenectady, New York
    10/12/2018
    Q
    Can Tenacity Herbicide be applied with a hose-end sprayer?
    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 and that can lead to less than desirable results.

    Q
    Can Tenacity be applied to Kentucky Bluegrass to control invasive fescue?
    I had some bugs and or mold kill small patches of the lawn. Fescue grew in and filled those bare spots. Will tenacity kill the invasive fescue? Can Tenacity be applied in the winter or fall as a pre-emergent?
    A

    Tenacity Herbicide is labeled for use on Tall Fescue, Kentucky Bluegrass, Centipedegrass, Buffalograss, Perennial Ryegrass, Fine Fescue, St. Augustine Grass, so no it will not kill the fescue in your Kentucky Bluegrass lawn.  Tenacity is a systemic pre-emergent and postemergent herbicide for the selective contact and residual control of weeds in turfgrasses. When applied as a pre-emergent, Tenacity Herbicide should be applied before soil temperatures reach 55 degrees. 

    You can spot treat the fescue with a non-selective herbicide such as Killzall and reseed with bluegrass.

  • Asked by Rivk from Augusta County, Va
    03/12/2019
    Q
    Can I use Tenacity as a preemergent on crabgrass and nimblewill?
    A

    Tenacity is labeled as a pre and post emergent for crabgrass but only as a post emergent for nimblewill. The most effective product to control nimblewill pre-emergently has been removed from the market (MSMA). We have had a lot of folks report that Dimension does a pretty good job pre-emergently but since the product is not technically labeled for nimblewill we cannot legally recommend it for this use.

  • Asked by Fred from Newport
    04/03/2019
    Q
    Can Tenacity be used for Nimblewill?
    A

    Tenacity Herbicide is labeled for application for post-emergent control of Nimbleweed to established cool season turf. Per the product label, you may need a second application after 2 to 3 weeks. Apply to young, actively growing weeds, and be sure to use a surfactant such as Southern Ag Non-Ionic surfactant for post-emergent applications.

    04/06/2019
    Q
    Does the soil have to be above a certain temperature to use Tenacity?
    A

    Tenacity Herbicide may be applied when soil temperatures are around 55 degrees or higher for post emergent control.  If you are using a pre-emergent you would need to apply before soil temps reach 55 degrees.

  • 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 Mike from Rockford, Il
    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.

    Q
    Does a long storage time reduce the efficiency of Tenacity?
    Tenacity worked wonderfully on my lawn when I first got it but I have stored it for approx. 3 years and the stored product does not seem to be working at all to kill weeds. I stirred it thoroughly before adding to water in sprayer. I used the recommended 1/2 tsp. per gal. of water.
    A

    Tenacity Herbicide if stored in a cool dry area will last up to 3 years. It sounds like you need to purchase fresh product. The mix rate you are using is correct.

    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 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.

    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.
