Rated 4.1 out of 5 by 168 reviewers.
Rated 4.0 out of 5.0 by suggested concentration is too low This stuff usually works well for me, but I usually mix in higher concentration. After reading several comments about this not working well anymore for some, perhaps the following info that I just used to answer a question might be useful enough to repeat here. Product description says that 6oz per gallon "offers the best results." (But note that many spray bottles these days are 1.33 gal, not 1 gal.) But if you look at the glyphosate concentrations in the MSDS for this and the 1.33 gal spray bottle, you see 18% and 2% by weight. According to google, glyphosate is 1.7X denser than water, so adding 6oz to 1 gal water seems to give a concentration of 1.4%. A little algebra later, I think you need to add 9oz to a gallon of water to get the same 2% concentration as the premixed stuff. That would mean the concentrate makes just over 3 gal, equivalent to the premixed versions. So I think it still works, but the concentrate is just more expensive than it looks. July 14, 2015
Rated 3.0 out of 5.0 by Directions and claim of ten gallons don't seem to match up The directions state to use 6 fluid ounces to make one gallon yet the claim is that the 32 oz bottle will make up to 10 gallons. This math does not seem to add up. I have just sprayed some of my weeded areas and am still waiting to see the results. I was disappointed that I will not be getting more out of the concentrated bottle. What do you recommend? Using 3 ounces for a gallon or the 6 stated on the directions? August 8, 2015
Rated 1.0 out of 5.0 by It is not killing morning glory in my grass. I have several patches of morning glory in my lawn. Weed and feed didn't do anything to it. I tried your concentrate on it and it killed the grass, but not the morning glory. What can I do to remedy this? I also included a picture of another plant that didn't get killed. I don't seem to be able to connect my phone to get the pictures. August 12, 2015
Rated 5.0 out of 5.0 by Kills grass as it states I needed to kill grass, decided to mix my own to same money instead of the pre-mixed stuff. I did, and it worked to kill the grass as it said it would. Make sure you dont' confuse this with weed killer--this stuff kills ALL VEGETATION - so be careful. I tried going with a "natural" product (vinegar) to kill the weeds growing up in my driveway cracks, but it didn't last long. This stuff works better and last longer . . . August 25, 2015
Rated 5.0 out of 5.0 by Read the instructions completely If you mix 6 ounces to a gallon of water then yes, you will get 5 gallons of spray. That is for heavier weed cover. Peel back and read the instructions and you will see that you can mix 3 ounces per gallon of water to get your 10 gallons of spray. This is for lighter weed cover and seedlings. Also, this product doe's take a while ( week and a half or two ) to show results, but once the weed is dead its not coming back. For those of you who doubled the quantity because you saw no results after one day, I just have to laugh at you. June 27, 2015
Rated 4.0 out of 5.0 by Works Like a Champ It kills weeds/grass like a champ. The only reason I gave it a four instead of five is because I think it should be a little more persistent. I know that there is an extended control formula but I still think this one could last a little longer. August 25, 2015
Rated 1.0 out of 5.0 by doesn't work This item does NOT work as intended. Which reminds me I have to call the manufacturer. May be they have to water it down to meet the CA standard. August 25, 2015
