Customer Reviews for Grass Out Max (Clethodim Herbicide)

Used this product to kill grasses in our Vinca Minor (Periwinkle) Ivy bed during mid-June NW Ohio, and in about 10 days the grasses were turning yellow and brown. Used Dawn dishwashing detergent as a surficant and gave them another shot on day 11. I would definitely buy again!

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.

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.

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

This has been an excellent product to kill grass that invades the Junipers and other plantings where grass does not belong. It is a little slow acting, but very effective at killing the grass, without harming the plant.

I was have issues with brome, bermuda, and johnson grass popping up in a new pollinator planting and could not use glyphosate due to damage the seedling forbs would suffer. Someone experienced in land management told me about this product and so far it has not harmed the forbs. I mixed on the lower side but it seems to be doing the job.

Tried Grass Out Max on newly planted alfalfa that had lots of grass. Took about 10 days to see results and it works really well. Also tried on Cowpeas and it is working on grass slowly. So far I am empressed with this product.

Grass Killers usually take longer to work much longer than your average weed killer which you see results in 3 days if not the next day grasses are different. It's not unusual to see products like this which is grass only killer work the way they do for the length of time it takes.

Although we are in the beginning stages of a drought, and the grass that needed spraying was stressed and tough, I decided to spray the my strawberries and around my blueberry plants. At first there did not seem to be any grass that appeared stressed. Then we got a quick shower and the younger grass began to yellow and then died. The older grass and Bermuda grass have begun yellowing. This means that the Grass Out spray is trans-locating to the roots and the yellow grass will die. Even long strands of Bermuda Grass which are growing out over gravel are yellowing and will ultimately kill the host plant to its roots. Grass Out is a great product that is deadly to grass and not harmful to my strawberry plants and to other broad leaf of the same type.

We recently had our sod removed and replaced with Perineal Peanut and Sunshine Mimosa. I was having a problem with Crabgrass growing within the ground covers and decided to try Grass Out Max. I tested a few areas and found that Grass Out Max really works as advertised. About a week after applying the grass blades started to look a little greyish in color. Within two weeks the grass was dead with no harm to the ground covers.

This is an over-the-top grass killer, meaning it won't affect most non-grass plants so you can spray it on weedy grass that is growing in beds among desirable plants. I sprayed it on heavy infestations of torpedo grass. The first effects showed at 7 days when the tips of the grass died. After about 2 weeks most of the grass appears totally dead and there was no effect on the surrounding desirable plants. I was impressed with this product and highly recommend it.

I'm using this to control weeds on my lawn, which is not grass but mini-clover. It has really helped us create a lovely clover lawn. In fact, if is full of little white clover flowers, which will eventually re-seed the lawn and ensure a robust result. Price is right, too.

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.

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.

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.

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.
