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.

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.
