    Q
    Will Tenacity kill unwanted grasses in Kentucky bluegrass turf lawn?
    Local extension office recommends Tenacity to kill off patches of fine fescue in a Kentucky bluegrass if applied at the rate for Kentucky bluegrass. What would that rate be and do you think this method will work well?
    A

    Tenacity Herbicide is labeled to be safely applied to fine fescue and is not labeled to kill it so we cannot recommend it for that use.  When you are trying to remove another cool season turf type from KGB the best option is to use a product like Roundup Quikpro (or non selective/glyphosate) and then re-seed with your KBG.

    Q
    Will Tenacity kill Thin paspalum?
    Have a lot of thin paspalum in the backyard in my St Augustine grass wasn't sure if Tenacity would kill it
    A

    Tenacity Herbicide only lists on the label that seashore paspalum is sensitive to it.  It is not however labeled for use on St Augustine lawns so would not be recommended. It can only be used on St Augustine grown for sod.

    Q
    Is there any benefit to ProGrass over Tenacity as a pre-emergent against poa annua on perennial rye?
    I live in Oregon and have primarily perrenial rye with some fescue.
    A

    Tenacity is only going to suppress poa annua when used as a pre-emergent for it. You would really only use Tenacity as a pre-emergent over the entire lawn if you are needing a pre-emergent to use at the same time as seeding or over-seeding. Otherwise, ProGrass would be a better choice for poa annua control and for use on established perennial ryegrass.

  • Asked by Joe from Eureka Mt
    06/14/2019
    Q
    How many applications of Tenacity Herbicide will be needed for bentgrass in the lawn?
    A

    Tenacity Herbicide is our most popular product for eliminating bentgrass from other desirable turfgrasses, but it does typically require multiple applications. Late summer/fall applications will be more effective than spring applications. If you are able to spot treat with RoundUp QuikPro, that is another option. It would still be ideal to wait at least 10-14 days after applying the Roundup QuikPro before raking out the dead plants and re-seeding those areas.

  • Asked by Lawrence from Wilmington, Il.

    Q
    Why do you not want to use a hose end sprayer while applying Tenacity Herbicide?
    A

    It is not recommended to use a hose-end sprayer to treat your lawn with Tenacity Herbicide or any other herbicide. The problem with using hose-end sprayers is that they are not very accurate, and you can wind up dispensing more or less product than recommended per area. This can lead to less than desirable results.

    Q
    Tenacity use on dormant near semi-dormant Bermuda grass
    After applying Tenacity to my dormant near semi-dormant Bermuda grass, It seems like the Tenacity killed certain large areas of grass. What is your recommendation to fix this issue? Will Bermuda grass overgrow that area or should I seed?
    A

    If the Tenacity Herbicide is used on semi-dormant grass, it may harm the turf as you have seen since it is only labeled to be used on fully dormant bermudagrass. You can wait it out to see if the bermuda grows back or you would wait at least 3-4 months to reseed.. The label does not give a specific time frame of reseeding with bermuda when Tenacity is used but since it is shorter-acting than other pre-emergents so as long as the residual of Tenacity is gone, you can reseed/sod.

  • Asked by Ray from New Jersey.
    04/07/2020
    Q
    How much longer before yellow colored patches turn green after using Tenacity Herbicide?
    I applied Tenacity as a preemergent the first week of March. 2 weeks later there are large straw colored patches. To date surrounding areas are green and patches are still there.
    A

    It depends on what type of turfgrass Tenacity Herbicide was applied to. If the grass is labeled tolerant to the product then it will bounce back as long as it's a healthy lawn. We would recommend to contact your county extension office to identify if it's a disease.
