    Q
    How do I apply Tenacity Herbicide for Kentucky Bluegrass?
    "Unless renovating and/or re-seeding the home lawn, avoid broadcast applications of Tenacity for pre and post-emergence weed control because undesirable whitening of some turfgrasses may occur." What turfgrasses are susceptible to whitening? I have a Kentucky bluegrass, Perennial Ryegrass mix.
    A
    Tenacity Herbicide can cause lightening of turf grasses labeled as not tolerant. The application rate you should use to ensure the Kentucky Bluegrass and Ryegrass will not lighten is no more than 5oz per acre.

  • Asked by Peter from Oklahoma City, Oklahoma
    05/24/2013
    Q
    Which pre- emergent is best for control of nutsedge
    Every year i have problem with nutsedge weed. Can you suggest which pre- emergent is best to use.
    A
    Nut sedge is a summer weed that is hard to control using a pre emergent. A great post emergent to ponder over is called Sedgehammer. SedgeHammer herbicide kills nutsedge without injury to turfgrass, established ornamentals, shrubs, and/or trees. SedgeHammer provides post-emergence control of both purple nutsedge and yellow nutsedge. SedgeHammer also controls many broadleaf weeds and suppresses kyllinga. Nutsedge is controlled after emergence in cool and warm season turf grasses such as St. Augustinegrass, Bermudagrass, Kentucky Bluegrass, tall and fine fescue, and perennial ryegrass. Sedgehammer is considered one of the more "gentle to turfgrass" products and pets and people can return to the treated area once the spray dries.

    Q
    How long after application of Tenacity Herbicide should I wait to reseed?
    I will be using Tenacity to control Nimblewill, and my lawn is perennial rye and fine fescue.
    A

    Generally, if you are treating with Tenacity Herbicide and using a tolerant seed, the applications can be done at the same time. If not, we would recommend waiting three months after the application of Tenacity Herbicide to re-seed your lawn. If you have any specific questions, we would recommend giving us a call at 866-581-7378.

  • Asked by James from Virginia
    07/17/2019
    Q
    Do I pull up white weeds after using Tenacity?
    Bought some tenacity from you and spot sprayed on my crabgrass. It has been white for about a week and seems to be dying. My question is, will it just disappear on its own once dead, or will I need to pull or rake the dead stuff eventually?
    A

    No, We would not recommend pulling up any weeds because the product will not get into the root system, and the weeds may come back at that point. 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 Per

    Q
    Nimblewill and Crabgrass Post Emergent Treatment - Rain
    I want to do Post-Emergent Treatment of Nimblewill and Crabgrass cool season turf with mix of KYB, Fesue and Rye. What is the amount of time the Tenacity should dry before rain or irrigation? Should it be irrigated for Post-Emergent treatment? The overall area to be treated is 4300 sq ft. The weeds are dense in a 1600 sq ft area and then sparse (spot treat) through the rest of the turf . Is the dense weed area considered spot treatment, so that 1/2 tsp per gallon or is it consider large area treatment using the higher rate of 1 tsp per gallon ?
    A
    After treating with Tenacity you want the product to have at least 6 hours of dry time before any rain or irrigation occurs. You do not want/need to water after a post emergent application. We recommend using the spot treatment rate of Tenacity in the dense areas so as to not cause damage to your lawn. Tenacity is known due to its power to even with an accurate application to sometimes temporarily whiten the turf surrounding the weed areas. The color will normally return within 3-4 weeks so to minimize the chance of turf discoloration you will want to use the lower dose at first and be cautious to not overlap or too heavily apply the product. Please let us kow if you have any other questions.
