    Q
    Will Grass Out Max also kill the sod where I am trying to kill annual blue grass invading my lawn?
    would like to kill the blue grass invading my sod grass
    A

This would not be a product you would want to use over a sod lawn and instead you would want to go with a product that is selective in either a pre or post emergent form. If you let us know what kind of lawn/sod you have, we can find a product that would better suit your needs.

    Q
    What type of herbicide is beset for Johnsongrass?
    It is around all of the bushes around the house on 2 1/2 acres coming up through medium sized river rock.
    A
    Grassout Max is labeled to control Johnsongrass and will not harm any ornamentals or bushes that you spray it over. According to the product label you will want to use between 12-24 oz per acre. If you use the highest dilution ratio which is often needed for something as hard to control as johnsongrass, you would use roughly 0.54 ounces per 1000 sq/ft feet in no less than 2 gallons of water to get sufficient coverage through the rocks to the roots in the soil below.

    Q
    Will Grass Out kill Zoysia that is growing in Mondo Grass and Euonymous, without harming them?
    A

    Grass Out Max (Clethodim Herbicide) would not harm ground covers like Mondograss and Euonymous when used as directed on the product label.  It is not labeled to kill zoysiagrass so we cannot recommend it for this use.  Typically a glyphosate based product would be used to control it in these areas with care being taken to avoid contact with desirables.

  • Asked by Jackie from Los Angeles,ca
    03/25/2018
    Q
    Can Grass Out Max (Clethodim Herbicide) be used on a Fescue lawn for treating annual bluegrass invasion?
    A

    ? Grass Out Max? is specifically designed to kill any and all grasses it is sprayed on and ONLY kill grasses. This would not be a product you would want to use over a lawn and instead you would want to go with a product that is selective in either a pre or post emergent form. Because poa annua and and fescue are so closely related, there are few products that will kill the poa annua without also harming the fescue.  The only one we are currently aware of is called Prograss. Your other options would be to either spot-treat with a Roundup-type? product and then reseed with the fescue in those areas, or you can use a preemergent like Prodiamine 65 WDG in the fall to prevent the poa from growing in the first place.

  • Asked by Shawn from Wi
    06/27/2018
    Q
    Can Grass Out kill all grassy weeds in my lawn EXCEPT Kentucky Blue Grass?
    My lawn is full of grassy weeds, annual bluegrass, foxtail, Quack grass, etc. If I wanted to broadcast apply something to my entire lawn, kill everything undesirable leaving only the Kentucky Bluegrass in-tact, is this the product I'm looking for?
    A

    Grass Out Max is a non selective grass killer, meaning it will kill your KGB as well.  A better option would be use Q4 for everything but the quackgrass and the poa annua. Unfortunately there is not an herbicide that would kill the quackgrass nor poa annua without damage cool season turf, such as Kentucky Bluegrass. If only a small area of the lawn is affected by the outbreak, spray only the affected area with RoundUp Quick Pro. If the problem amounts to no more than a few spears of quackgrass in an area of your lawn, paint the individual spears with diluted RoundUp QuickPro. Becareful to avoid getting the product on desirable grass. If most of the lawn has been affected by quackgrass, the only sure fire way to get rid of it is to spray the entire lawn with Roundup. Spray when the lawn is growing actively, preferably in the spring. The treatment will kill the lawn grass as well as the quackgrass. After about two weeks, you may begin the replanting.

    A

    Grass Out Max (Clethodim Herbicide) does not list that it will control Kentucky Bluegrass only annual bluegrass.  A better option would be a glyphosate based product like GlyPhoSel Pro taking care to avoid any spray/drift to desirables.
