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.

I used a lawn company till this year, my problem has always been Poa Annu Bluegrass. bought this product appplied 1 oz per gallon with my hose end sprayer results were visible 2-3 days after use. Use a sufflant also. bought the smaller size this time but will buy the bigger next year for two applications at separate times. NO MORE LAWN COMPANIES WASTING MY TIME AND MONEY!

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.

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.

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'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.

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.

Does what it says. Perineal beds are over sprayed once in spring.... no grass weeds all summer. It's very effective and does kill ornamental grass so be careful... will not harm shrubs or other non grass plants.

Only killed Johnson grass. Other grasses are still green and strong after 2 weeks. Applied 16 oz. per acre.

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.

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.

Upon arrival the box was half soaked with the grass out. The seal /cap was loose. I am thankful the shipping box was wrapped in plastic, however the product was quite strong.
