    Q
    Kill Perennial Rye grass but not Kentucky Bluegrass?
    Will this kill off Perennial Rye grass in a mostly Kentucky Bluegrass (KBG) lawn without damaging the KBG? Cool Season Zone 6b. If not, is there anything that will? My front lawn is less than 2k sqft and don't want to burn it all down because there's still good KBG. I overseeded Rye into my lawn in Fall 2022 and hate how it looks.
    A
    Grass Out Max is a non selective grass killer, meaning it will kill your KGB as well. Unfortunately there is not a selective product that will remove one cool season lawn from another. The only approach will be to spot treat the rye grass with a non-selective such as Roundup QuikPRO - 5 x 1.5 oz. packs

    Q
    Right now my bermuda grass is dormant. Can I spot spray winter weed grasses in my bermuda lawn with Grass Out Max?
    If I spot spray grass out max on my dormant bermuda grass, to kill winter weeds/grasses, will it damage it? There is going to be no rain in next 7 days.
    A

    Grass Out Max (Clethodim Herbicide) is not labeled to be used bermudagrass turfgrass as it is for controlling it in cool season turfgrasses and other areas. Keep in mind that if the soil temperatures are below 55 degrees a post-emergent may not work. We generally recommend uaing Roundup QuikPRO - 5 x 1.5 oz. packs when Bermuda is completely dormant as it gives the best results even in colder temperatures

    Q
    Will Grass Out Max keep zoysia, poa, Bermuda, etc. out of my tall fescue lawn?
    If not what product will.
    A

     Grass Out Max (Clethodim Herbicide) is designed specifically for killing grassy weeds including fescue in ornamental areas without harming desirable shrubs and roses, it is not for use in lawns at all.  

    Since poa annua is so closely related to cool seasons grasses, like fescue and ryegrass, there are not any herbicides that can be applied to kill the poa without also harming the fescue and ryegrass. We do have one product called Prograss EC Herbicide, but it is very expensive. We recommend spot treating the poa annua with a glyphosate product and then just reseeding those areas.  

    Unfortunately, we do not carry any herbicides that are labeled to kill zoysia in a tall fescue lawn. You will either need to spot-treat the unwanted grasses with a glyphosate product like Roundup Quik Pro and reseed.  Fusilade II can be used to get rid of Bermuda grass in tall fescue.  You will also need to add a nonionic surfactant for best results.  Please be advised that Bermuda grass is extremely difficult to control and you will likely need to make several applications. With Fusilade II Herbicide, it is recommended to apply the product in the early morning hours or late evening hours when the temperatures are below 85 degrees Fahrenheit.

    Q
    Is Grass Out Max safe to use on Sunshine Mimosa, Perineal Peanut and Beach Sunflowers?
    The landscapers that removed our grass and planted the above ground covers did not remove all the crabgrass roots. We now have crabgrass growing in the ground covers.
    A
    Grass Out Max (Clethodim Herbicide) is labeled to be used safely around sunflowers and Perennial peanut as tolerable to applications but does not mimosa.  We would recommend testing a small area of the mimosa before applying over the top completely.
