    Pre-Emergents typically should be applied in the spring before ground temperatures reach 55 degrees and again in late summer/early fall. For more specific recommendations based on the current climate of your region we would recommend contacting your loacal Master Gardener.

  • Asked by Keith from Glenside, Pa

    Q
    Can I spray Tenacity at time of seeding?
    When using Tenacity at time of seeding do I first spray the soil then seed or do I seed then treat the area? The exact steps I assume I would take would be: scratch-up the dirt as to loosen so the seed works into the soil, treat the now loosened soil with Tenacity, last step spread the seed. Guessing you don’t want to spray the seed with Tenacity. This should then greatly reduce the weeds in the treated are for about 4 weeks.
    A

    Tenacity is an effective herbicide for weed control prior to or during seeding of certain turfgrasses during turf renovation. Please see section on use in New Seedings in the Product Label for complete instructions and limitations for your specific turf type.

  • Asked by Keith from Delavan Wi
    05/19/2014
    Q
    Will Tenacity kill creeping charlie?
    A
    Tenacity is labeled to control Ground Ivy "Creeping Charlie" as post emergent control. We highly recommend using a temporary turf colorant like Turf Mark Blue so that you can see where you spray with the Tenacity to avoid overlapping. Tenacity is a great product, but also a very strong product so too much overlapping or mixing the product too strong can cause temporary damage and whitening to your turf around the ground ivy. The color will come back in the lawn after 3-4 weeks but to avoid this potential problem it is best to use a colorant to make sure no overlap occurs. To get optimum results for post emergent control it is recommended you use a Non Ionic Surfactant in your mixture as well. Please make sure that you check the label to verify that it is safe for your type of turfgrass as you did not indicate the kind of lawn you will be applying the product to. Please let us know if you have any questions.

  • Asked by Robert from Orlando, Fl
    05/14/2018
    Q
    Is Tenacity Herbicide a good choice crab grass control in Centipede grass?
    I live near Orlando, FL and have centipede grass. What is a good product that I can use for general weed control? I have several areas with weeds, but not all over the entire yard. I'd like something I can put in a pump sprayer. I know one of the weeds I have is crabgrass, but not sure what the other ones are.
    A

     

    Tenacity Herbicide? would be a great option for you to control crabgrass, along with many other common weeds, without harming your Centipede lawn.  Tenacity needs to be tank mixed with a non ionic surfactant? or the best results and stick to the leaf surface of the weeds, and its 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. According to the Tenacity product label you will need to mix 1/2 tsp of product + 1 1/2 tsp surfactant with 1 gallon of water for spot treatments. After spraying with Tenacity Herbicide, the foliage of treated weeds cease growth after application, then turn white (loss of chlorophyll), and death may take up to three weeks. A repeat application is required after two to three weeks for improved postemergence weed control.

  • Asked by Eric from Lexington, Kentucky

    Q
    Should I spray Tenacity on Bentgrass before dethatching or after?
    My 2,700 sq./ft. backyard is 30% Bentgrass and 70% healthy and thick tall fescue. I want to kill as much Bentgrass as possible and overseed my lawn this fall. The Bentgrass patches I can't even see the soil for the amount of thatch. Should I spray Tenacity @ 3 apps, dethatch, then over seed? Or should I dethatch, spray @ 3 apps, over seed?
    A

    In general, we would recommend killing the undesirable plants and clearing out the dead plant debris before dethatching and then reseeding the lawn. Dethatching will be easier and you will get better germination with your new seed when the ground is better prepared for it. You can learn more about these treatments in our Do My Own Lawncare Video Series, too. You can find them on the bottom of our Lawn Care Guides page here.

  • Asked by Jack from Harrison City, Pa. 15636
    08/13/2019
    Q
    How do I mix Tenacity Herbicide?
    I want to broadcast spray my entire lawn. 4,000 sq ft Thanks.
    A

    Tenacity Herbicide calls for 5 to 8 oz of per acre, unless treating St. Augustine turf grown from sod, you would use 4 oz per acre. If you plan to use Tenacity at low rates of 5 oz per acre then you would use 0.11 oz per 1000 sq/ft or  0.45 oz per 4k sq/ft. If you want to use the high rate of 8 oz per acre then you would use 0.18 oz per 1000 sq/ft or 0.72 oz per 4k sq/ft. Be sure to use at least 1 gallon of water per 1000 sq/ft that you treat, and mix your non-ionic surfactant into the tank at the rate of 2 teaspoons per gallon of water. Spray foliage of target weeds until wet but not until the point of runoff. If a reapplication of Tenacity is needed, you can reapply after 2-3 weeks from your initial application.

    Q
    Is Tenacity Herbicide Safe on Spruce Trees?
    Can I spray this product as both an herbicide and pre emergent in and around blue spruce ornamental trees (weeds emerging through bottom branches)? If yes, what is a safe application rate?
    A

    Tenacity Herbicide  could pose a discoloration if it gets on the bark. You want to try and make the application on a day that is not very windy. According to the Tenacity product label you will need to mix 1/2 tsp of product + 1 1/2 tsp surfactant with 1 gallon of water. Tenacity will also act as a pre emergent for listed weeds.

    Q
    Will Tenacity Herbicide kill wire grass in our tall fescue?
    A

    Wiregrass is a form of bermudagrass.  The product label states that bermuda grass is sensitive to Tenacity but it would not be recommended as a product specifically used to kill it.  Fusilade II can be used to get rid of bermuda grass in tall fescue.  Please be advised that bermuda grass is extremely difficult to control and you will likely need to make several applications.

  • Asked by Joel from Martinsburg, Wv
    07/05/2017
    Q
    Can Tenacity Herbicide be mixed with products like Ortho Weed B Gon?
    A

    You could potentially mix Tenacity Herbicide with other products as long as you follow both product labels to be sure you are using the correct rates for the area you want to treat. We also recommend checking the labels first if you are planning on seeding or have recently done so. We also suggest a small jar test before mixing a large batch to check for compatability.
