Customer Reviews for Grass Out Max (Clethodim Herbicide)

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.

  Expert response:
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.

Bought this last winter so I'd have it when warm weather hit and the grass started growing again, Grass has been growing for about 1 month now, sprayed 3 times and grass is still green and going strong. I won't say don't buy this product because it might work for you, but I wouldn't buy it again or recommend it . Its been a waste of my time and money.

  Expert response:
Thank you for your comments! You did not mention whether you used a surfactant when applying the Grass Out Max. You are very unlikely to get satisfactory results using Grass Out Max or other clethodim products without the addition of a surfactant, such as Southern Ag Non-Ionic Surfactant for Herbicides: http://www.domyownpestcontrol.com/nonionic-surfactant-for-herbicides-p-1771.html We appreciate your feedback and your business!

Instructions are for acres, not per gallon for smaller scale. Had to guess and 3 days later I can see no difference in the grass.

I followed the directions religiously like I have done with every other product in my yard over the last 20 years. The end result is that my front lawn, Zoysia, is now 90% dead and I have more weeds than I do grass. Here it is the middle May & I am going to have replace my entire front lawn. I have used many such products in the past and have never been so disappointed. One bottle of this product will end up costing me thousands of dollars. Be warned.
