Rated 1 out of 5 by from No good Have the same problems as everyone else's reviews mixed it a little on the heavy side and weeds still look green as ever even with temps in the 90s and no rain. It could be sold as fertilizer and no one would know the diff

Rated 4 out of 5 by from Super Weed Killer This goes against the direction but if you mix it 50/50 with water. It will kill within 36 hours. Works best if you don't get a rain. It will Kill!

Rated 1 out of 5 by from Not worth the time or money I used this in a sprayer to kill an acre of weeds and clover for a food plot. It didn't do a thing after 2 weeks. Did it on an 80 degree summer day with no rain for a week after. I will have to purchase something else and do it all over again.

Rated 1 out of 5 by from Doesn't work I bought this product and mixed it at 10% to kill grass along the side of driveway. It's been 10 days and the grass is still green. No rain and temp is in the 90's. Will not be using this product again... Back to what I know works... ROUNDUP...

Rated 5 out of 5 by from Works great I have an acre that is yet to be landscaped. We used this product to clear/prep the soil for seeding. It did the job. I would recommend this product to anyone wanting to knock down large amounts of weeds.

Rated 5 out of 5 by from Good Product I have used this killer the last few times I have sprayed. It does exactly what it is intended to do. As mentioned In other comments, it is most effective if 2oz is mixed per a gallon of water. With this mixture and 80deg F temps it takes approx. 3-4 days to completely kill the grass and weeds (may vary in different climates). In my opinion it out performes the other brands with a smaller price tag. Only makes sense to use it.

Rated 5 out of 5 by from THIS IS NO BRAINER I am a single mom who bought a house with a large back yard full of poison ivy and another kind of prickly ivy that was everywhere. I was totally overwhelmed in reading the process of getting rid of this stuff effectively. My kids were not allowed in the back yard... until.... I found this product. I bought a sprayer, and a bottle of this stuff, 2 weeks later -- no poison ivy, no vines, all dead. That was last year, I thought the true test will be how will it hold up? This year, I had very few small pop ups of regrowth, but this was yard full of it, where nobody maintained it. I am a happy girl, this stuff rocks. I use it also to carefully edge my driveway. NO WEED WACKING for this chick anymore. I love this stuff, its the magic wand you are looking for.

What is the difference in this product and the FarmWorks Grass & Weed Killer 41% Glyphosate concentrate 2.5 Gallon for $54.99? I have used this product with great results but it appears to be more expensive than the FarmWorks product...

Asked by: Jefany
This product has the same active ingredient as the 41%, it is just a little more concentrated. The mix rate for the 50% would be a little less (2-2.5 ounces per gal) than the 41% ( 3 ounces per gal) for general weed and grass control.

It can be safely used around existing trees as long as no drift or spray gets on the trees.

Can I safely use this product on dormant Bermuda lawn to kill other grasses and weeds? I don't see that use on the label.

Asked by: Philip MH
Yes, Groundwork 50 % Super Weed & Grass Killer can be used on a dormant Bermuda lawn to control weeds and grasses. The Bermuda needs to be fully dormant or it will be killed along with the weeds. Daytime temperatures should be in the 60’s when applying to make sure the weeds are active and take up the product.

Does this kill Knotweed?  I didn't see any label on the website.  If you had to suggest a product to kill a large (almost an acre) of knotweed what would it be and which one would be the cheapest?

Asked by: farmer diana
Yes, it will kill Knotweed. Please check your email for additional information concerning the specs and label.
