Customer Reviews for Grass Out Max (Clethodim Herbicide)

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.

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!

Had Johnson grass try to take over my sunflower plot this spring, and the Grass Out Max used with Surfactant took care of the problem!

I used to spray mixed clover food plots. Mixed as per instructions using suggested oil to help aid in contact. Works well. Have patience it will not kill overnight. Takes about 12 day's and grass in clover plots was dead and clover was unaffected. Will save lots of time with plot maintenance.

Effective and reasonable price for grass control in clover food plots. Same active ingredient as Arrest Max.

Sprayed 12 Oz/Acre 8 hours before a 1/2 inch of rain and almost all grass in my food plot turned brown within 1 week. Remaining grass was brown and dead by the end of 2nd week. Plot was planted 4 weeks before application and has clover, winter peas, alfalfa and turnips which never showed signs of stress.

I sprayed 3 gallons via a backpack sprayer on my clover plot on 5-18 20. Was back out there today, 5-27-20, and the grasses were looking like there are heading for being dead. It is not an instantaneous kill but it is working like it should. The clover looks great with all the grasses dying out. I am very pleased.

Sprayed grasses in food plot at about 3”, after 2 weeks it looked like a 50/50 kill off. I sprayed again, we'll see what the results are in a couple weeks.

Love this stuff for killing grass in my food plots. Customer service scores 100%. I had a package arrived damaged, and I called and it was fixed immediately.

The product worked great. I used it on my food plots which had a lot of foxtail, among other unwanted grasses. After 1 week, I could see that some grasses were starting to die off, but not all, so I sprayed a second time. I probably could have been more patient, but I wanted to make sure I hit everything. 2 weeks after the first application, I really noticed the results. I bought this with the surfactant, as suggested, and I was really pleased.

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.

Used to eradicate some stubborn grasses from my brassica/clover plot. Took about 10 days to show full effect, but the grass is gone and my crop looks to be fine. Will use this again if needed.

Sprayed clethodim on my arrowleaf clover to kill thick bermuda and it did the job. As others have reported it takes 2-3 weeks. Bermuda was very thick and now it's beaten down and the clover should make a great plot on into fall.

Followed directions and the grass laughed at it. Doubled the amount and it did kill some but not a lot.

I wasn't sure how well this would work. Killed the grass in the wife's flowers and in a patch of crimson clover. It took about two weeks to start seeing results. Everything looks pretty good. Product arrived quick.

Although we been having lots of rain in Florida, I mixed and sprayed the grasses growing up through out ground cover beds. That grass is turning brown now and our landscape plants were not affected. I'm gonna spray over it again soon but it may not need that, I just want to be sure it's killing it. I'm thinking I'm done pulling grass out of our landscape borders from now on.

Being new to this product I was a little concerned (a lot concerned) about spraying my tomatoes wit this product but I give it a try. The first one I used it I only sprayed 1 row of tomatoes and was careful not to spray the tops of them. It didn't hurt the tomatoes and after a few days my grass was turning yellow. So I sprayed another row and was not as careful about not getting the spray on the tomatoes and again after a few days the grass was turning yellow and the tomatoes were doing good. Then I got brave and sprayed the rest of my tomatoes and sprayed grass and tomatoes and now 2 to 3 weeks later I have pretty tomatoes that are grass free. I did mix the spray as directed. I recommend this product.

I recently bought a 16 oz. bottle of grass killer. When it arrived the post office wrapped it in a garbage bag. The bottle had leaked and was saturated with this stuff and had a very pungent odor. The bottle was missing a cap and the inner seal had leaked to the point of being almost empty. I called DoMyOwn and was told that all i had to do was send them a picture of the bottle and I would have the option of another bottle being sent or a full refund. I took the refund as I had already found another product to do the job. They were very helpful and understanding. I will do business with them again and think more people should feel that they are trustworthy to stand behind there products and service.

First off, the included pamphlets are very detailed and you might need to calculate the proper application for your situation. All that being said, I read a review that said to use 0.4 fluid ounces per gallon of mixture with 0.35 fluid ounces of a surfactant. This calculation was correct for my application once I worked out the proper rate from the pamphlets. I have an atv mounted 20 gallon sprayer that I use to spray food plots and around the house for all my needs. I needed this product to treat a field of sunflowers for wildlife on my property. I mixed the recommended rate that I received on this website and it really worked! All the field grasses were killed with the sunflowers looking not to be scathed. The product does take some time to work so don't expect a 24 hour turn around like some herbicides promote. It takes about a week to 10 days to work. I'm very happy with this product and this website to provide the insight into the specific application for my needs. I am now thinking to use this product on my flowerbeds and garden beds that get infested with grasses after I work so hard to prepare the areas. I'm going to research the provided pamphlets to ensure I'm mixing the correct dosage but this website does provide a valuable resource with their expertise.

I had received misinformation which was corrected with a second call to DoMyOwn. This product needs a surfactant combined with it. It works and hasn't damaged my jasmine. However, a second application may be necessary after a couple of weeks. Check with DoMyOwn regarding amounts to mix with water. A little goes a long way for homeowner gardeners.

I've tried a few other products to eliminate the grasses from beds of myrtle and other ground covers. Nothing seemed to work. After two applications of the Grass Out Max, the unwanted grasses are disappearing from view. The little bit of die-back in the perimeter lawn areas was not unexpected. I used a wetting agent to ensure good contact with the grass blades. Total success might not be evident for a couple of months, but results to date have been very positive.

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 have used this product twice. The first time more as a test to see if it damaged recently planted clover. I choose an area in my yard where grass had completely taken over the clever. In about a week the grass turned yellow then dried out. The clover is starting to grow better. The second time was only four days ago. About half of the grass is yellow and the clover is looking good. I mixed a little more than an ounce to 5 gallons of water and some surfactant. I may spray again in a week.

This is a herbicide that is specific to grass species. Does not harm most other types of plants. BUT read the very detailed instructions carefully!! Some (a few) ornamental plants could damaged by this Grass Out Max, and there is a comprehensive list in the instructions. I used this in flower beds/landscaping where invasive grasses like Bermuda were growing in and around desired ornamental plants. I have seen a pretty good kill of the grasses. However, my area was starting to get pretty dry when I sprayed. The instructions will tell you Grass Out Max is effective on actively growing grass, but not as effective on drought-stressed grass. I have a few areas I will have to respray after the grass gets some water. Two things to know: this Grass Out Max has to have time to travel through the grass blades (leaves) down into the roots. You won't see the grass dying for several days. Be patient, it's working. Second, shield adjacent lawn grass areas from the spray ( I sprayed with a 2 gallon tank garden sprayer), use a tarp or something similar. Remove right after you spray, and be careful not to allow the part of the tarp that has wet spray on it to drag over the grass. Overall very satisfied with results I got.
