RoundUp sold for residential use no longer includes glyphosate, which I was specifically looking for. This product was well priced and is working bit by bit to bring my overgrown fence line under control. It will last as long time, used at a low concentration.

This is easy to mix and easy to use. If you know how to use it the results are fantastic. This is a much higher concentration than the Round brand you find Up at garden centers. (See what I did there? 😎) Understanding glyphosate is the only way to make this work. It hinders the water uptake from plants and it is foliar so it must be absorbed through leaves. If whatever you want gone is not actively growing—this won’t work. If whatever you want is drought-stressed—this will not work. Example: I have an area of Bermuda in my lawn that grows the neighbor’s Dallisgrass. I hit this in two shifts last year and will tackle another area this year. Shift 1: The Bermuda is about to go dormant and turn brown. Perfect. Because this is a foliar product I can blanket spray on dormant Bermuda with no issue. It will kill anything else growing that has green leaves. Like Dallisgrass. Shift 2: Dallisgrass comes out of dormancy weeks before Bermuda to attempt and shade the grass to compete for nutrients. Once it wakes up I will hit it again even harder with this stuff because it will be more actively growing. At this point if the Dallisgrass survives, it has earned the right to do so. The best way to use glyphosate is to water regularly, fertilize regularly, then hit the leaves of what you want gone with this herbicide. It takes about a week to fully eradicate and sometimes 2 applications because it has to be absorbed through the leaves. You’ll notice results within a few hours but that’s just drought stress. In 4-6 days it will be a bare patch. I highly recommend this product.

I not sure what this is made for but it is not weed killer. I have 5 acres of fence and driveway to spray so I mixed 4 1/2 ounce per gallon a week ago and used dye with it so I don’t miss anything and not have to go back and do the spots I missed. I’m going to have to respray everything it didn’t kill anything. So I’m out my time plus what I paid for this junk and the dye which is going to make it harder with the dye already on the ground I’m not going to know what I sprayed with the new unless I can find a different color dye to use. Have to update my review it does kill weeds and grass it takes about 7 days before you can start seeing the grass die and about 12 days and it is all brown.

I bought a bottle of this 2 years ago to kill off a big briar patch. I’ve been trying to kill these briars for the last 20 years. I’ve tried everything. You were supposed to mix just a little bit and think about an ounce in a gallon of water. I mix three times as much as I was supposed to in a gallon of water. Bought a $20 sprayer and went out and sprayed the briars. They are never coming back. This stuff is amazing. The one thing I will say is do not spray it near a tree if you live in the woods. If you get close enough to big tree, I do believe it would kill a big tree. But if you have any vegetation that you want dead, this will work.

I tell you, this weed/brush killer is SOOOOOOOOO effective!! Without reservation, It really really works. Following the instructions, this concentrated poison will KILL. But the amazing part is that it's the only one I found on the market that will clear and allow you to replant 1-2 weeks later. REALLY. Once it is absorbed by the living plant, the plant WILL DIE in 1-2 weeks. But while waiting, you can replant without facing any danger to the new plantings. So about once a year, I buy only enough to spray-edge the lawn, spray sidewalk/gutter cracks for the entire season. If I see a weed or two growing strong, one spray on the leaves & it will be dead in a week - NO PULLING WEEDS. I even had a few weed-trees growing behind my garage inside cracks. so i sprayed all over the leaves & everything died in about 2 weeks even though it rained the day after my application. I think it's too dangerous to retain, so I only buy the smallest amount & dispose of the rest responsibly.

Used to be very good product . Very watered down. Non-effective for full and complete kill of weeds. Weeds turn yellow but don’t completely die. They eventually overcome the stunt and thrive again.

It does one supposed to do in Gilles the grass and the weeds wherever I put it. I spray about a 6-in path all the way around my house next to the driveway and around the mailbox because I don't want to ever run a weed eater. I can spray my front and my backyard a couple times a year and don't have to waste a minute trimming. I'll buy it again when I need it.

Takes a few days to work but foes a great job.I dont have grass just dg and soil and rocks but the weeds still grow strong esp after the winter rain in So. Cal. This spray is easy to mix with water in my electric sprayer and always kills the weeds after a thorough application.

Effective, but I have found thicker-blade grass to be quite resistant to this, needing 2-3 daily applications and about a week before seeing things die off. It can kill off larger plants with larger stalks and leaves, but these can take 3-4 applications and a couple weeks. Thin grasses respond within 36+ hours to a single application. But overall, yes, it does get the job done. Everything eventually withers away... you just need to be aware that not everything withers away at the same time or with the same speed.
