Ground Application
Use a minimum of 5 gallons and maximum of 40 gallons of spray solution per acre. Use of sufficient spray volumes and pressure is essential to ensure complete coverage.
Under the following conditions a minimum of 10 gallons per acre is required: narrow row soybeans, broadleaf herbicide tank mixes, perennial grasses, volunteer corn, drought or stress conditions heavy grass pressure or when grasses are at or near maximum height. Failure to use a minimum of 10 gallons per acre under these conditions can result in poor coverage and reduced grass control requiring repeat applications. Spray pressures should reflect a minimum of 30 psi and a maximum of 60 psi at the nozzle. Do not use flood nozzles.
Applications to onions (dry bulbs and green), garlic, and shallots (dry blubs and green) should be made in a minimum of 20 gallons of spray solution per acre.
Grass Out Max

I barely applied the product and cannot say yet how effective it is. The product information booklet is extensive, but never states how many ounces to a gallon sprayer for use in home perennial beds. It says 8 oz. for an acre. I am guessing 1/2 oz./gallon for home use, but guessing is uncomfortable.

Good grass killer
By Joseph on 08/04/2014
I purchased this product to use on my food plots. It arrived timely, and I mixed the product with 2.5 oz per gallon of water. I mixed in some sticker as indicated, and used a backpack sprayer to apply. I didn't see any immediate action (first couple of days) but finally noticed that it was working. It took out the crab grass in my clover field without harm to the clover. My plots are about 1/3 acre; I would suggest that you map out a route to insure complete coverage if you use hand sprayer like I did, as I missed a few spots do to walking deviations. I recommend this product for use in food plots.

Takes Patience, But Very Effective
By Happy on 09/29/2012
We have about 12000 square feet of lawn with curbing and beds throughout. Kentucky bluegrass creeping into the groundcover of the beds used to be a real problem. Then my neighbor introduced me to to Grass Out Max. He had used it the previous fall and his beds look great. He said it took about a month for it to work. I tried it and it and for the first couple of weeks didn't see much difference, but after a month it did the trick. Now just an occasional touch up application keeps the beds looking good.

grass out
By Rusty on 01/12/2015
I don't think the product works. I have applied it twice and at this point no action. unless it kills the grass soon it was wasted money.

Grass Out Max
By Mike on 06/20/2012
I need to know how much to use of the Grass Out and the Surfactant. Do you mix it together and what is the percentage of each. Thank You.

I have completely read the product label and the answer to "per gal.concentrations" questions which will not do! I have a garden with irregular shaped flower beds where it is impossible to estimate 1000 square feet for the amount of 0.2-0.4 oz. Grass Out Max. Like most people in my situation I will be SPOT SPRAYING throughout these beds. How much per gallon is necessary for an effective concentration to kill on contact regardless of the area covered?!!!
There is an applicaiton ratio for spot treaments on the product label for Grass Out Max (Clethodim Herbicide) as well. You would mix .33 oz - .65 oz. per gallon of water.

I'm using Grass Out Max in a gallon sprayer for flower beds. In reading the labels, I can't find what amounts of grass max/water to use for that size container. Could you please give me that information?
