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.
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.
Thank you for your review. I apologize that the label is extensive and confusing. We recommend using a surfactant like Non-Ionic Surfactant to help increase the efficacy of this product. If you use the surfactant, the recommended mixing rate for one gallon would be 2 tsp of surfactant with approximately .4 oz of the Grass out per gallon of water per 1,000 sq feet. Please let us know if you have any other questions.
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.
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.
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.
What kind of plants are you trying to kill, and around which desirable plants? This product should be used with a surfactant, so you will only see limited results if you have applied it without adding a surfactant/spreader sticker to your diluted solution.
You may also see limited or slower results during this time of year since the grass should be actively growing in order to absorb the herbicide.
We would be happy to troubleshoot with you via email or via telephone at 866-581-7378 9a-5p EST.
Can Grass Out Max (Clethodim Herbicide) be used as a spot treatment in flower beds?
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?!!!
What is the mixing ratio of Grass Out to water for spraying flower beds?
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?
You will need to use 0.2-0.4 fl oz of Grass Out per 1,000 sq ft area. Like most other herbicides the exact amount of water you use is not important, it is just important to make sure you get the specified amount of product over a 1,000 sq ft area. For ease of mixing/measuring you can add the specified amount of product to 1 gallon of water to apply to a 1,000 sq ft area.
