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.
Date published: 2019-04-28
Rated 4 out of 5 by from Easy to order I am about to spray with this today, and from experience know that it takes quite a bit more time than Roundup to manifest that it worked, but as long as the concentration is there it will do the job for a good price.

Rated 1 out of 5 by from FarmWorks 41% Glyphosphate is defective I bought 2.5 gallons of this product. I have sprayed the same weeds now 4 times over 3 months and they are not even close to turning brown. It could be a bad anbd defective lot but beware. I have even increasded the concentrtae level each month way past the instructions of 2 OZ per gallon. This product does not work.

Rated 5 out of 5 by from r FarmWorks Grass & Weed Killer I Have been using farm works for a couple of years now and it’s been amazing but everyone else’s found out about it and it’s hard to find on the shelves
Date published: 2018-12-23
Rated 2 out of 5 by from Don't waste your money. I should have researched some before buying. I get better results with nearly any other brand of glyphosate. Its cheap for a reason. I'll stay with the good stuff.

Rated 1 out of 5 by from Disappointed I've used this product in the past with some success but I purchased a container last month to spray some weeds around the yard and driveway and mixed it a little stronger than recommended and results were disappointing. Some weeds turned yellow and some are still Green and growing. Would not purchase this product again!

Rated 5 out of 5 by from Great Grass Killer for the price. I used this to spray fence rows. I mixed 2.7oz/gal. and killed everything including multifloral rose bushes.

Rated 4 out of 5 by from It's Slow, But It Does Its Job I recently bought the Farmworks Glyphosate weed killer to spray on my lawn; initially, I saw little, if any results. But once it kicked in to the root system, it killed EVERYTHING it touched. I am pleasantly pleased with the results it produced and would recommend it again.

Rated 5 out of 5 by from Great Weed Killer This will be my 3rd year using this. Its the only thing that I found that really works and does what it says. Using this you have to spray before your grass turns green and it feels great to see your neighbor's mowing weeds and you don't have to mow.

Rated 2 out of 5 by from Disappointed in the long run I have bought 2 containers of this. It kills everything but in a couple months I have a full yard of weeds again. I even raked the ground for seeds but made no difference. Was hoping to kill the weeds so they won't overtake my lawn when I seed but am finding I need to just seed and than use something like weed and feed or. Sure didn't give me my clean slate to work with.

Rated 5 out of 5 by from I love this stuff... I love this stuff...Works very well but only mix the amount you plan to use. Goes bad and will clog your sprayer
Date published: 2016-08-27
Rated 5 out of 5 by from Great Stuff I use this ALL the time. Kills everything. Takes about 7 days to kill it and a few applications to kill trees. I killed a 20' pine in 4-5 applications. Was surprised it worked. Used about a 2 % solution. I use a 1-2% for everything else.
Date published: 2016-07-23
Rated 5 out of 5 by from Works great Bought this glyphosate as the quantity and concentration is much more than you would find at the big box stores, and its premixed with surfactant. Killed the grass along my fence lines and everywhere I sprayed it. Glyphosate works by blocking proteins plants need to make food, so it took 4 days before I began to see the effects. Spray on a sunny day with temps over 75 degrees for best results. Do not spray if rain is expected within 24 hours. Read the instructions on the label to determine mixing concentration and do not stand downwind to where you are spraying.

Can it be used in ponds to kill moss and duck weed

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.

Is this product harmful to bees?

Asked by: J D T2

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

Will this kill Johnson Grass? Is it safe for horses who live in a pasture that gets run off? Also, is it safe for properties with a well?

Asked by: Sobejets

How quick can you plant a garden after using Rm18 to kill the grass before planting your garden?

Asked by: Rabbit55
Yes. Give it about 7 days. RM18 works quicker in warmer weather than in colder.
