    First off, its g/L

    The concentrate is 6 times more potent than the RTU

    So 60 ml of the concentrate in 1 L of water would give you the same percentage of active ingredient as the RTU

    The math doesn't work out ! it would still work out to a mix ratio of 167ml of concentrate to liter of water to get the same comcentrations as the RTU stuff of 10g/L

    This is not Roundup. Nor glyfosate. It is a quick-acting burn down product. The retail product is called "Finale" around here. Works quickly, but not as good for anything with deep roots.

    The concentrate is 6 times stronger than the Ready-to-Use. Take one ounce of concentrate--add 5 ounces of water--and you are at the ready-to-use concentration.

    10/1 = 60/6

    Guess thats right.....

    Its not that simple if you look at the overall contents based on their labelling

    Its more like this 10g/1L 10g/1000ML = 0.01g/ML and 60g/L 60g/1000ML = 0.06g/ML

    So if the RTU contains 10g/L then to get the same amount in the concentrate mix, you would need to add 0.06 x 167ML = 10.02g

    Which is roughly makes 6 bottles of the stuff if I use 167ml/L, but the instructions on the concentrate tells you to mix ONLY 33-66ml/L which is 2.5 -3 times less than the RTU stuff

    Before I make any statement about this, I would like to see a label for both that lists the percentages of the AI in each package. I don't know this product or do I care to, But I feel my math is good enough to get a correct answer. The given weight of the AI is not the best way to do the correct math.

    Its mentioned on their site and on the label is identical.

    Ric's right.........If you're talkin' Roundup Pro, Clean Cut, or Prosecutor: 4 - six ounces per gallon in a spot sprayer -- 5 quarts per acre when tank mixed. But even then, you have to know what weeds you're going after cuz the rate changes. Read the label for sure -- then mix it slightly stronger and add in spreader/sticker. We like UAP's LI-700 -- it's a spreader/sticker/acidifyer/penetrant. It has a really bad stench, but boy does it work! p.s. We also mix in ester broadleaf herbicide (Chaser) which shows results within 48 hours.

    I don't believe you are understanding what I am asking For. Let me give you an example from Roundup Concentrate and Roundup Ready spray.

    Roundup concentrate is Glyphosate.........41%

    Roundup Ready to spray is Glyphosate.......1.5%

    Now without explaining the math 1.5% Roundup ready spray is equal to adding 2 oz of 41% to a gallon of water. By knowing the Percentages of each product I can tell you the mix rate and the Number of gallons you will get from a bottle of concentrate. In the case of Roundup you can get 64 gallons of 1.5% weed killer from each gallon of 41% Roundup.
