  • Asked by John from Eighty Four, Pa

    Q
    Will Tenacity Herbicide kill Poa Annua and leave my rye and blue grass alone?
    A

    Tenacity Herbicide is not labeled to control Poa Annua/Annual Bluegrass in a post emergent application, it only states that it could cause injury to it if sprayed. Kentucky bluegrass and ryegrass are tolerable to it so would not be harmed.  It is only labeled to be used for suppression of poa annua when used as a pre-emergent.  Unfortantely there is not a post emergent product that would remove it and not harm the KGB as they are too similar.  We recommend that you spot treat the poa annua using a non-selective herbicide such as GlyPhoSel Pro. Your best option for poa annua is to use a pre-emergent herbicide more suited to preventing it like the Prodiamine 65 WDG.

    Q
    If Tenacity is applied to a pasture how long do you need to wait before allowing grazing?
    A
    We contacted the manufacturer Syngenta since Tenacity is not labeled for use on pasture land and they told us that you would need to wait 90 days before turning animals out to graze in treated pastures.

    Q
    How late in the year can Tenacity Herbicide be applied?
    I purchased Tenacity from you earlier this year. I applied it twice in June, two weeks apart. The nimblewill got a little white, but came back strong. I haven't been able to reapply it because we've had grandkids around. How late can I use it again? How much should I use in a one gallon sprayer? I also purchased and used the Spreader Sticker. Thanks!
    A

    Tenacity Herbicide is a pre and post emergant so it can be applied at any time of the year, where the weeds and grasses you are treating are still actively growing with temps consistently above 55 degrees.  Per the product label you would use .5 tsp of tenacity in one gallon of water.

    Q
    What is the shelf-life of Tenacity Herbicide?
    I plan to use this for spot treatments on small areas of bentgrass. Using only 1/2tsp per gallon, an 8oz bottle is going to last me at least a few years. What is the shelf-life of this product?
    A
    If stored in a cool dry area,  Tenacity Herbicide will last up to 3 years.

  • Asked by Michael from New Hampshire
    07/18/2019
    Q
    As a post-emergent, is there any advantage to waiting longer than the 2-3 day recommended minimum to mow after applying Tenacity Herbicide?
    In other words, will leaving the treated blades/leaves attached to the plant for as long as possible (say 7 days) allow the product to be more effective or work faster?
    A

    It is safe to mow areas that have been treated with Tenacity Herbicide 2 days after application.  After that time the product would have worked into the plant enough to not be affected by mowing.  Delaying mowing does not help it work better.

  • Asked by Theresa from Killingworth Ct
    05/31/2014
    Q
    Will Tenacity kill creeping ground ivy also known as creeping charlie or creeping jenny?
    A
    Yes, Tenacity is labled 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.

    Q
    Will Tenacity Herbicide kill Bermuda grass?
    I am in KY, and I have a real problem with Bermuda grass .The product label says Bermuda grass is sensitive to it. I need something that will kill it.
    A

    The product label states that Bermuda grass is sensitive to Tenacity but it would not be recommended as product to eliminate it since it is not labeled for this use.  Fusilade would be a better option depending on your turfgrass.
