    Q
    Is a surfactant recommended for use with Grass Out Max?
    A

    Grass Out Max is a selective post-emergent herbicide used to control annual and perennial grasses. It is labeled for most landscape, home and garden, ornamental, agricultural and non-crop uses including strawberries. Please refer to the product label for complete usage instructions for your application. The manufacturer does recommend adding a surfactant for better results.

    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

    While you did not state what kind of grass is in the sod that you have down, the 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 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
    I want to use Grass Out Max (Clethodim Herbicide) to kill grass but not newly planted clover.
    I'm confused about the statement only in the States of Idaho, Oregon, and Washington. Your Q&A isn't any help on this. Can you send me a sample to try on a small area so that I can be sure it doesn't kill my clover?
    A

    We apologize,  but we are not able to send out samples of  Grass Out Max.  The manufacturer has only registered it for use on clover in the listed states.  When used as directed it will not kill clover and will kill grass only.
