Rated 4.0 out of 5 by 56 reviewers.
Rated 1.0 out of 5.0 by Not worth the money Bought a gallon in the spring and it's gone. Killed weeds only to have them back in less than 3 weeks. September 5, 2015
Rated 1.0 out of 5.0 by Did not kill anything!!! I was glad to read that I wasn't the only unhappy customer. I wanted something that would kill my weeds and wasn't happy with another brand I was using. After reading the ingredients and percentages I went with the Round Up Super Concentrate. I used it the first time, NOTHING died. I re-read the mixing ratio thinking I may have mixed it wrong, but I did not. Made up another batch 2 weeks later and again nothing died. What I have left I'm going to be tripling dosage and see what happens. Will not buy it again. August 3, 2015
Rated 1.0 out of 5.0 by Worthless product. Wasted my money and time with this roundup. This roundup super concentrate must be a bad batch. I wasted my time and money with the application of this product. It did nothing to any of the weeds I sprayed. And yes I know how to follow directions and spray. I worked professionally in a greenhouse spraying all kinds of products. This roundup I just used did nothing on even the easiest to kill plants. Several hours of spraying on five acres and I'll have to start all over again. With a different brand. Very disappointed with roundup. August 6, 2015
Rated 5.0 out of 5.0 by Been using it for years. I've been using it with the Dial N spray on the same steep slope for years. Works as advertised. I also keep a pump sprayer on hand (2.5 oz gal) for sidewalk and isolated garden weeds. Again, all as advertised. July 1, 2015
Rated 5.0 out of 5.0 by long distance strength Had a weed start to grow at the top of my chimney. I'm 59 and not going up three+ stories on a ladder, but had to get rid of the weed. Mixed up some Round Up, loaded a super soaker, pumped and fired. 2 days later....weed is dead. June 23, 2015
Rated 4.0 out of 5.0 by Kills everything. I have used many many gallons and it works great. The World Health Organization states that the glyophosphate.... may cause cancer. June 24, 2015
Rated 4.0 out of 5.0 by My backyard is a mess. Nothing but sunflowers, pigweed, and some weird grasses. Over night it went from a few inches to a few feet in height. After using some other brands, and still having weeds as tall as my house, I decided on trying this. It's only been a few days and most of the weeds are dead, the rest are wilting and dying, YAY! In 3 weeks I'll have the yard I want, not weeds. It' s really easy to use, and really concentrated. I've been sharing with the neighbours, and we've all had great success. July 20, 2006
Rated 5.0 out of 5.0 by This purple one works great I started using roundup many years ago. I have also tried many different kinds of weed killer, which non of them work nearly as good as roundup. You mix it per the instructions, spray it on and wait. Some of the weeds are easier to kill than others, so just be patient and all of them will die. Just make sure you don't spray it on anything you don't want to die. April 22, 2015
