    Q
    If killing the old grass and replanting new grass seed, will Grass Out Max (Clethodim Herbicide leave a residual in the soil that will prevent new grass seed from germinating?
    I'm looking for a quicker way to kill the existing grass so the tiller process can be quicker. If this does leave a residual in the soil, can I add 1 or 2" of fresh soil on top that will help the new grass seed germinate?
    A

    If you are looking to kill all existing grass/plants in an area so that you can reseed with a new or different type of grass, the best way to do this is with any Roundup or non selective type product. Roundup and similar items on the market like X-Out and Avenger will will burn down the existing vegetation and break down in the soil within 1-2 weeks to allow you to replant without fear of damage to the new seed.

    Grass Out Max would require you wait at least 30 days after an application before planting new seed. If you wanted to bring in fresh soil that does not have chemical residual in it you are welcome to do that.

    Q
    Dilution of Grass Out Max (Clethodim Herbicide)
    You right .4 oz is that the same as 4 oz? I'm reading .4 ounce as 4/10 of an ounce.
    A

    If you are referring to the product label for Grass Out Max referencing 0.4 fl. oz. / 1000 sq. ft., then you are correct in that 0.4 oz. is less than 1 oz., and would be the equivalent of 4/10 oz.

    Q
    Will Grass Out Max kill poa that is growing in rye grass that also has dormant Bermuda?
    I live in Bakersfield where we overseed our Bermuda grass with Rye each winter.. The Rye has Poa growing in the shaded areas of lawn. If i spray it now over Rye/Poa will the Bermuda be safe? And is it pet safe once dry?
    A

    Grass Out Max (Clethodim Herbicide) is a grass killer and would kill both the rye and the bermuda.  To kill poa annua in rye grassm, you would need to spot treat with a glyphosate based product such as Gly Pho-Sel Pro.  These grasses are closely related so there is no selective product label to kill one that would not also kill the other.  If you still see poa once the Bermuda is no longer dormant, you can use a product like Certainty.

  • Asked by Harold from Plymouth, Nc

    Q
    Can Grass-Out Max (clethodim herbicide) be used in a Centipede lawn to kill bermuda grass?
    A
    Since Grass Out is a grass killer in general we do not recommend you try to broadcast spray it over your centipede lawn as it may cause damage. We have heard of many people using Atrazine to control Bermuda grass that is invading a centipede lawn, though because this is actually an off label usage we cannot say for sure that it will work. You can also choose to spot treat the bermudagrass growth with a glyphosate product and just reseed int hose areas.

  • Asked by Terry from Covina, Ca
    04/26/2015
    Q
    What's the difference in these two Clethodim grass killing products?
    "Grass Out Max" has active ingredient Clethodim at 25.4%. You also carry Select "Source PS Clethodim Herbicide" which shows 26.4% and specifically lists Bermudagrass BUT is not for sale in several states. What is the difference in these two? Does that extra percent qualify PS as prohibited? It's also nearly twice as expensive.
    A
    Grass Out Max and PS Clethodim are basically the same product with a very small variation of active ingredient percentage. However, this variation in the percentage of Clethodim does not determine eligibility for sale and/or shipping to certain states. Each state has a registration process for herbicides and in this case the manufacturer of PS Clethodim which is Prime Source has not registered their product in several states. Therefore, when a product is not registered with the state it may not be shipped or sold there.

    Q
    Will Grass Out Max (Clethodim Herbicide) hurt my centipede grass?
    I have bermuda grass and bahaia grass in my lawn that I want to eradicate.
    A

    Since Grass Out Max (Clethodim Herbicide) is a grass killer in general we do not recommend you try to broadcast spray it over your centipede lawn as it may cause damage. Unfortunately centipede and bermuda grasses are so closely related that any product that would kill the bermuda would also kill the centipede. In this type of situation, we usually recommend using a glyphosate product such as Roundup Quik Pro to spot treat the bermuda grass as much as possible, and then replanting the centipede in a couple of weeks when the bermuda is gone.

    Q
    Will Grass Out Max (Clethodim Herbicide) kill Canadian and Bull Thistle? If so, when is the best time to spray?
    I have tried many different products, organic and not, and the thistles keep coming back year after year. Even tried digging them out and that just seems to make the thistles multiiply the following year. Recommendations?
    A

    Grass Out Max (Clethodim Herbicide) is not labelled for Canadian & Bull Thistle. Tenacity Herbicide is labelled to treat Canadian Thistle, but doe does not list Bull Thistle. Herbicides containing glyphosate like Roundup QuickPro can effectively control bull thistle. Mowing may need to be repeated throughout the season to prevent reflowering
