      Glyphasate?
      ByAug 2, 2026
      1 Answer | 
      Answer This Question

      Hey there, Robert. Great question. The active ingredients in Roundup Weed & Grass Killer4 are Triclopyr, Fluazifop-P-butyl, and Diquat Dibromide. As of 2023, none of our residential-use products contain Glyphosate as an ingredient. This mixture of active ingredients work to cause uncontrolled cell division and growth, ultimately causing the weeds to grow themselves to death. If you have additional questions about product use, please don't hesitate to reach out at 877-270-3089. We're here to help!

                  Don’t waste your money
                  This product does not work at all. I sprayed four gallons of it on my pool pavers and on the driveway. The weeds never died and now have so many more. So disappointed and mad about all the wasted money. Will never buy again. I wish I had my receipts to get a refund.

                    Almost two months ago, my family started to use Roundup Weed and Grass Killer recommended by neighborhoods. After compared with other brands used before, Roundup is the best driveway weed killer for sure. The picture attached is showing the driveway before and after the usage of Roundup Weed and Grass Killer. I like to recommend Roundup to my friends,

                    This product kills everything! It is perfect for pesky weeds in our driveway, sidewalks, rock beds and mulch beds. Paired with an HDX sprayer for extra ease in application.

                    It works great, but make sure you spray to the week only because it will kill everything even though it is good grass.

                    Product works as it should. Basically kills all weeds, grass etc. that it comes into contact with. Easy to spray directly on undesired plant growth. This product is easy to use safely and I do not hesitate to use it regardless of media publicity. Common sense should be used during application to avoid direct contact with skin, eyes, or breathing etc. Kills weeds and they do not return. Overall very please with this product and continue to use it at my residence and business without hesitation. Great offer was also available, buy a gallon with sprayer and get a free one gallon refill.
                    by
                    This product kills weeds and grass as advertised. It’s Roundup, who reads a review about Roundup? Who writes a review for Roundup? I have included pictures of dead weeds and grass, they are dead because they were sprayed with Roundup.

                    Great product , product works really well around the house with pets or animals this product does the trick seems to kill all the unnecessary unneeded weeds. Use during cool or not so hot once it sits for 24 hours I would recommend spread a little water on it so the product can get down into the roots
