    Answer This Question

    A:  There is 35.2 ounces in the container and it takes 6 ounces per gallon so I makes about 6 gallons of solution.

    by|May 25, 2023

      A:  Roundup Weed and Grass Killer Concentrate Plus can be mixed at 2 different rates. 3 oz per gal of water for annual weeds and 6 oz per gal of water for perennial and hard to control weeds. This container is 35.2 ounces. You can make between 5.8 and 11 gallons of solution depending on which rate you use.

      by|May 19, 2023

        A:  Approximately 6 gallons.

        by|Jun 2, 2023

          A:  Depends on the strength you are mixing. See directions for the different mixture strengths, choose the one you will be using. Divide the bottle size ounces you are considering by the amount you will be needing per gallon, multiply the number you get by 1 and you should come up with the total gallons your considered bottle should make.

          by|May 22, 2023

            A:  Instructions say it makes “up to 11.7 gallons” when mixed.

                  Stars are only for product effectiveness. But what a scam....
                  Stars are only for product effectiveness. But what a scam. My old Roundup bottle contained 36.8 ounces and was labeled “Value Size”. The bottle I purchased yesterday is the same bottle and contains 35.2 ounces. Nonetheless corporate megalith Bayer labeled it “Larger Size”. If Bayer can’t do simple math why should I trust their aspirin? Truth in advertising?

                  Great Product
                  [This review was collected as part of a promotion.] This concentrated plus Roundup pesticide killer is very effective controlling all unwanted weed and grass that grows in not desired areas. It is simple to use just by mixing 6oz to one gallon of water, the product came with a measuring lid to make the job easier. It takes at least 24 hours or more to see results. After using this product I can say that is effective and won’t harm pets or peoples skin, just follow instructions provided on back of the product for proper use and storage recommendations. The Roundup Concentrate Plus Weed and Grass Killer performs well and as expected.

                    Deader than a door nail
                    [This review was collected as part of a promotion.] I have used Roundup products for years. As you will see from before and after photos, it gets the job done. I just found my target and even used a Roundup sprayer which targeted my prey very accurately.

                      Very effective
                      [This review was collected as part of a promotion.] Roundup Weed and Grass Killer is fast and effective! Literally overnight I saw amazing results out back where I fight tall water weeds. The smell is not noticable and it's super easy to use, small enough to store anywhere and is of great value. Compared to other weed and grass killers, I prefer Roundup simply for it's fast results and ease of use. I definitely recommend and will repurchase.

                        Amazing
                        [This review was collected as part of a promotion.] I like that this bottle includes a small cup to help you measure to add the water with this product. This product helps your side to prevent any unwanted roots grow between the small cracks of the sidewalks.

                          [This review was collected as part of a promotion.] I like the Roundup Concentrate Plus Weed and Grass Killer, 36.8 oz. It comes with an Easy Measure Cap. Just add 6 oz of concentrate to one gallon of water in your sprayer. I’ve definitely noticed an improvement in my lawn. No more weeds! Roundup is a brand I trust to get the job done. Definitely recommend.

                            Effective liquid and fast results

It is simple to use just by mixing 6oz to one gallon of water, the product came with a measuring lid to make the job easier.

                              The Roundup Concentrate, a Killer
                              [This review was collected as part of a promotion.] The Roundup weed killer has been applied to an area with weeds, substantial in numbers as well as size. After two days it was obvious that the product was at work. See enclosed photo. The Roundup Concentrate Plus Weed and Grass Killer performs well and as expected. The concentrate was easy to mix with the measuring cup on top of the bottle.

                                Very easy to use
                                [This review was collected as part of a promotion.] I absolutely love how easy it is to use. I poured a cap full into my spray container and filled the rest with water. I sprayed my fence area and my driveway area. I don’t think it worked the first time due to rain coming in within the 30 minutes of me spraying it. Overall; very easy to use and concentrate it.
