Good grass killer but needs a little something extra to ensure kill
Good product for removing invasive grass species. For anyone who has had slow results or only seen their grass yellow but not die, suggest adding 1/2 of one percent Glyphosate to the mixture. The Glyphosate really turbo charges this product and is such a low percentage that non-grasses are not likely to be hurt. I sprayed Japanes Stiltgrass that had ferns mixed in and the grass died but the ferns were fine.

Don't waste your money
I have used this in the past and loved it. This time it has not killed one blade of grass. I don't know if it was old or improperly stored or what, but I just wasted my time and money. Applied it three different times to be sure. Soooo disappointed.

Seems to be working
These photos have been taken one week from application and I will wait until the third week to see if a second application is required . Some grass has browned, some has turned purple, and there is some completely green and unaffected but it has only been a week.

You also need crop oil.
We have a problem with Bermuda grass in our flower beds. This product works well to control Bermuda grass. When I ordered it I did not realize that I would also need to have crop oil for this to work well. The crop oil helps the product to adhere to the grass. Without the oil the product just evaporates too quickly to be effective.

It works! It works!
I purchased this because when seeing last autumn a bunch of seed ended up in my garden. An AI search result recommended this product. Upon receiving it the instructions made it appear like it was intended for weed type grasses as opposed to lawn grass (in this case, tall fescue). I tried it anyway. Within a few days all the fescue in the garden was dead and the vinca was fine!
