Rated 1 out of 5 by from Must be a bad batch The last 14 gallons I purchased may 2 2019 must have been a bad batch. We have used farmworks for years and we normally see brown down within 5 to 7 days. Not with this batch though. Have sprayed twice since 5-2-2019 and fields are still bright green. The cost of the concentration is only a small part of the cost of using it. You also have to figure in the cost of oporating the machinery to apply it. When your tractor uses 3 gallons of fuel a hour to run it gets expensive to fix some chemical company's screw up.

Rated 5 out of 5 by from A+ It worked great! It takes a few days for it to work but when it does it kills it all.

does it kill bitter weed and can it be used on pasture and hay meadow

Asked by: bilstam
It will kill all the grass it is sprayed on too but It can be used in a pasture. Expect everything it is sprayed on to die so don't spray any pasture grass you want to keep.

What is the difference between this product and Compare N Save Concentrate Grass & Weed Killer 41% Glyphosate. Both are carried by Tractor Supply and Distributed by Ragan and Massey, Inc

Asked by: srubenda
Farmworks and Compare N Save Grass and Weed Killer are both 41% glyphosate. Farmworks has a much broader label and has a lot more approved uses.

Will this help prevent future growth like Round Up Extended? If not, is there a product that will? I would rather not have to apply this once every two weeks.

Asked by: DeadEye637
No. But Tractor Supply has another product that will do just that--RM43

Could you tell me how many oz to use per gallon of water with a hand pump sprayer Your manual is a little over wellming for me

Asked by: 2061
Per the Vendor: "“I know our label is very extensive and allows for lots of different mixing ratios based on what kind of weeds you are trying to control. For general weed control and tough weeds I use 6.5 ounces per gallon."

I want to kill grass and weeds around fence line and trees without killing trees or bushes. Will this work? If not, any products to recommend?

Asked by: Tmo502
It will only kill what you spray it on. So if you don't spray the trees and bushes it won't kill them. Be careful around them and you should be alright.
