  • Asked by Ray
    03/30/2020
    Q
    I applied Tenacity on my turf grass during the first week of March. At least 90% of the lawn is light yellow
    In color 3 weeks later. How long would it be before turf returns to green? I live in NJ.
    A
    Yellowing or whitening of the turf after a broadcast application of Tenacity Herbicide is caused by the loss of chlorophyll. The product label states, "Tenacity may cause temporary whitening of turfgrass foliage. In general, symptoms appear five to seven days after application and last for several weeks. A repeat application to the same site causes less whitening of the plant tissue."

    Q
    I keep bees in my back yard. Can I use Tenacity on the bentgrass without harming my bees?
    A
    Tenacity Herbicide could potentially harm bees if they come in contact with the treated area. We recommend contacting your local cooperative extension office and speak with the master gardener in your area for advice on product that will not harm bees.

    There are patches in my yard that have a bright greenish color. It really stands out. Will Tenacity take care of this.

     Tenacity Herbicide is labeled to take care of this. Be sure to mix a surfactant like Non Ionic surfactant to help promote the product to stick.

  • 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.

    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

    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.

    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.

  • Asked by Domenic from North Royalton, Oh

    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.

  • Asked by Charles from Metropolis, Il
    08/26/2017
    Q
    What do you mean "after a post emergent application" when referring to watering after using Tenacity Herbicide?
    A

    Tenacity Herbicide can be used as a pre-emergent or a post-emergent. A post-emergent application on Tenacity Herbicide would be to kill weeds that are already there. The product does not need to be watered in after application. For a pre-emergent application, the product is used to prevent weeds from coming up. It is recommended that you water the product in 1/2 inch after application to get the product into the soil.

    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.

  • Asked by Ceasar from Splendora, Tx
    02/01/2018
    Q
    How many times per year can I spot treat using Tenacity?
    A

    There is not a specific limit on the number of spot treatments that you can make using Tenacity Herbicide as long as you do not exceed the annual maximum of 16 oz Tenacity per Acre or per crop. Typically you would wait at least 2-3 weeks between applications to the same areas. Be sure that you follow all the product label instructions as far as timing with seeding and other restrictions.
