    Q
    Will Tenacity Herbicide kill orchard grass?
    A

    Tenacity Herbicide is not labeled to control orchardgrass. Unfortunately, we do not know of any selective herbicide that will kill orchardgrass without harming your desirable turfgrass.  It is usually recommended to spot treat the orchard grass as much as possible with a non-selective product like RoundUp QuikPro, and then replant in those areas in a couple of weeks when the orchard grass is gone.

  • Asked by Jacky from Elk Grove, Ca

    Q
    Are these the correct Pre-Emergent and Post-Emergent applications with Tenacity Herbicide?
    I wanted to confirm if I am correct with the following: Pre-Emergent -- when using as pre-emergent, you spray your entire lawn. Post-Emergent -- When using as post emergent, you will spot spray the weeds. Thank you,
    A

    In general, this is correct. Tenacity is typically only used as a pre-emergent when seeding or over-seeding with turf types that are listed as tolerant on the product label. For post-emergent weed control, you should just spot treat to avoid whitening on your desirable turf.

    Q
    I have a smith contractor 2-gallon sprayer that I plan to use for applying Tenacity Herbicide at 1 tsp per 2 gallons. How do I know I am applying enough or too much? Is there a way to calibrate or is just spraying a blanket good enough?
    A

    We would suggest testing the flow rate and pace of walk using the 2-gallon sprayer with plain water to determine the best nozzle setting before treating with Tenacity Herbicide. You want to be sure you are walking at an even pace and evenly spraying the area for best results.

    Q
    Does Tenacity work on Nimbleweed?
    A
    Tenacity is labeled for post-emergent control of Nimbleweed. 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.

    Q
    Will Tenacity Herbicide harm monkey or mondo grass?
    I have mondo grass as a ground cover with many weeds. What can I use to kill weeds and not the grass?
    A

    Tenacity Herbicide is not labeled as safe for use around Mondo or Monkey Grass. Surflan has been used for pre-emergent control of broadleaf weeds in Mondo Grass and for post-emergent control, Sedgehammer is commonly used. Please refer to the product lable for instructions and applications rates.

    Surflan - Preemergence weed control when applied to established ornamental plants before weeds have emerged. This product performs better with incorporation after application with irrigation, rainfall or light tillage.

    Sedgehammer - Apply in landscaped areas with established woody ornamentals. Do not apply over-the-top of flowers, ornamentals, shrubs or trees.

    Q
    Any application restrictions for lawns in N.Y. State with Tenacity Herbicide??
    How early in the Spring can you can you spray in this climate? How damp or wet should you spray to insure proper coverage?
    A

    Tenacity Herbicide is not restricted in the state of New York.  It can be applied when the soil temperature reaches 55 degrees Fahrenheit. This should be broadcast across the lawn in areas where you are wanting to prevent weeds. Be sure to water the product in 0.5 inches to activate it. This product can be applied right before it is going to rain. We normally recommend applying Tenacity in early to mid April in cool season areas.

    Please check out our Cool Season Lawn Guide for tips on how and when to use products in your lawn.

    Q
    Can I kill rye grass with Tenacity Herbicide? I live in the Northeast.
    A

    No, Tenacity Herbicide will not eliminate ryegrass.  If you want to eliminate ryegrass in cool season turf, we would recommend using Turflon Ester Ultra. The mixing rate is 3/8 - 3/4 oz. per 1,000 sq. ft.

  • Asked by Frank from Cleveland, Oh
    07/03/2017
    Q
    Would it be helpful to apply a greater amount of non-ionic surfactant in the mix with Tenacity Herbicide ?
    The recommended mixture seems to be a ratio of 3 to 1. IS it possible or allowable to mix a greater ratio of the surfactant (say 5 to 1) in order to insure that more of the herbicide adheres to the creeping bent grass & various other weeds ?
    A

    According to the manufacturer, it is not advised to apply more than the recommended amount of the non-ionic surfactant. We advise you to use the ratio recommended on the product label.

    Q
    Can you mix Tenacity with Drive XLR8 ?
    A

    As long as both products do not contain the same active ingredient, and both have labels that allow tank mixing in general. Per the Drive label: The most restrictive labeling applies with any tank mix. To increase spectrum of control of broadleaf and other weeds, Drive XLR8 may be tank mixed with 2,4-D, Triclopyr, and other broadleaf herbicides. Make sure to do a tank mix test first for any clumping or discoloring before applying to the lawn. Also, be sure both products can be used on the treatment area safely.

    Q
    Do I apply Tenacity to dirt before laying sod?
    Whole lawn has lot of bentgrass I think. If I replace with new sod. Do you recommend using tenacity on the dirt before rolling out new sod.
    A

    If you are doing a full lawn renovation and wanting to kill existing plants before sodding, then we would recommend using a non-selective herbicide to clear the area before planting. You could use a product like RoundUp QuikPro for this application. Then after any existing plants have died and the lawn is prepared, you could put down your sod. We would suggest applying Tenacity after the sod is down as a pre-emergent (or post-emergent as needed) as long as the turf is one that is listed as tolerable on the product label. Keep in mind that the best time to use Tenacity for bentgrass will be in late Summer/early Fall.
