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...

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.

I have some woodlands on my property..  Will this product be safe for the trees?  I only want to kill the weeds to seed grass, but keep my trees.. 

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

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.
