  • Asked by Steve from Pleasantville, Oh
    07/27/2014
    Q
    Will Tenacity affect all varieties of Poa?
    I have what I believe is Poa but am not certain of the variety (annua or other). How can I determine what I have?
    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.  It is only labeled to be used to suppress poa annua when used as a pre-emergent. We recommend to contact your Cooperative Extension Office and speak with the Master Gardener to identify the weed species you need to treat for.

    Tenacity is a systemic preemergent labeled to treat for Yellow Nutsedge only, but not does list other types of nutsedge.

    Q
    Is Tenacity safe for use in apple orchards in early spring?
    I have nimblewill weed in my orchard and would like to eliminate it
    A

    Tenacity is not labeled for use around anything edible so we cannot recommend it be used in an orchard.  We apologize but we do not currently have a product labeled for control of nimblewill in orchards.  However, you can click here and contact your local cooperative extension office to speak with a Master Gardner to find the name of a product and then contact us to see if we have access to that product.

    Q
    Can you spray Tenacity and Gordon's Trimec at the same time?
    A

    It may be fine to mix both Tenacity and Gordon's Trimec together but has not been tested by the manufacturer. We recommend that you perform a jar test to an inconspicuous area first prior to a full application to confirm if you wish to use them both together.

    Q
    Is it safe to apply Tenacity within a week of slice seeding Kentucky blue grass and rye?
    My lawn was slice seeded with rye and KBG 2 days ago. Is it safe to apply within a week of seeding? I was not able to apply during the time of seeding

    You should wait until the newly germinated turf has been mowed two times, or four weeks after emergence (whichever is longer) before making a postemergence application with Tenacity if it was not applied at the time of seeding.
