    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.

  • Asked by Jeff from Ct
    04/22/2021
    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.

  • Asked by John from Dallas Georgia
    04/29/2021
    Q
    I used Grass Out Max (Clethodim Herbicide) to treat for poa annua in my lawn which worked great however my lawn is now also brown? Did I kill my lawn also?
    A

    Grass Out Max targets grassy weeds like poa annu but also kills grasses including turfgrass. At this point only time will tell if the bermuda will recover. Product labels should always be reviewed and followed exactly to be sure they are used properly.

    For treating poa annua in bermuda you need to use a selective herbicide such as Image Kills Nutsedge for small areas, or Certainty or Negate for larger areas. Please review our How to Get Rid of Poa Annua Treatment Guide for more information.

    Will Grass Out Max (Clethodim Herbicide) kill billy buttons?
    A

    No, Grass Out Max is only labeled to kill grasses and will not kill broadleaf weeds, flowers, bushes, shrubs, or groundcover.

    For broadleaf weeds, Roundup QuickPro could be used around desirables as a spot treatment if wanting to eliminate billy button weed.

    Q
    When using Grass Out max is it more important to spray the targeted weed grass or the soil it is growing in?
    I want to kill specific weed grass plants growing in a shrub bed.
    A

    Grass Out Max (Clethodim Herbicide) should be sprayed directly on the grassy weeds themselves. It is highly recommended that you use a surfactant with this product for best results.

    Q
    Will Grass Out Max harm my Zoysia grass as I have Poa annua in it?

    Grass Out Max (Clethodim Herbicide) will likely kill your grass since it is only safe for ornamentals not for use on turfgrass areas. Image Kills Nutsedge Concentrate & Certainty Herbicide are both labeled to control poa while being safe on Zoysia lawns

    Q
    Would Grass Out Max be effective in controlling bamboo?
    We will be trying several techniques, including a non-selective herbicide but I would prefer to use a grass herbicide because other plants in the area would be affected by non-selective herbicide.
    A
    Grass Out Max will not be effective for Bamboo. Only non-selective herbicides applied at the highest usage rate directly to cut stumps multiple times has been proven to be effective for eliminating bamboo.

  • Asked by Philip from Cambridge, Md

    Q
    Can I spray this on Corn to control grasses as the corn emerges?
    A
    The Grass Out Max can only be applied to non-crop areas so this would not work for your needs. We are not as familiar with products that are safe to be used in agricultural areas as we are new to that side of products. We recommend contacting your local department of agriculture to get recommendations that local farmers use for weed and grass control in crops. Once they give you a product name or ingredient, give us a call and we would be more than happy to see if we carry it or can get it for you. 1-866-581-7378.

  • Asked by Steve from Scotts, Mi
    04/14/2014
    Q
    Can Grass Out Max be used on established spruce seedlings for grass control?
    A
    We would not recommend using Grass Out Max within 30 days of planting just to be safe as it could potentially damage the seedlings. If you can wait longer than a month (more like 6 weeks), then it could be considered as an option.

  • Asked by Larry from Lakewood Ranch, Fl
    08/09/2014
    Q
    Does Grass Out Max kill zoysia grass that has intruded into my ornamental beds or is another product better?
    A

    The Grass Out Max label does not specify yes or no if it will kill Zoysia Grass. We recommend contacting the manufacturer Agrisel directly at (770) 831-4160. Using a product such as Ranger Pro as a spot treatment will work to treat the areas where you have the Zoysia Grass invading, but it will also kill anything it comes into contact with.

    Q
    Will Grass Out Max work to eliminate grass from a baseball infield? And will it kill weeds to?
    A
    Grass Out Maxx is only labeled to control grassy weeds.  It will not kill flowers, shrubs, broadleaf crops or other broadleaf plants.  Agrisels Gly Pho-Sel Pro with 41% Glyphosate would be a better product to use, just be sure to only apply to the weeds/grasses you are wanting to kill as it can kill anything that it is applied to.

  • Asked by Michael from Belton
    03/18/2017
    Q
    Can I use Grass Out Max to get rid of Poa Annua in my bermuda lawn?
    If not, is there a post-emergent that is better?
    A

    We would not recommend using Grass Out Max on your bermuda lawn as it is a grass killer and will harm the bermuda as well. Grass Out Max is used to remove all grasses from places like ornamental/flower beds and vegetable gardens. If you are looking to remove Poa Annua from your bermudagrass lawn, if you have a small lawn or just want to spot spray you can use a product like Monument 75WG. If you have a larger area you need to treat then Certainty Herbicide would do a great job as well.

    Q
    Can I use Grass Out Max (Clethodim Herbicide) to control Kentucky bluegrass that is creeping in to sprawling evergreen bushes?
    A

    Grass Out Max  is not labeled for use on evergreen bushes. We would recommend using Gordons Ornamec Over-The-Top Grass Herbicide. This product will kill grass and is safe for use over evergreen bushes. You will mix 2.5 fl oz of product and 1/3 of a non-ionic surfactant.
