    I ususally put in 3 oz per gallon, of generic round up
    I dont know what the percentage is I would imagine it is 41 % I think 2 OZ per gallon would work,
    Rat is the chemical man around here maybe he will see this,

    I run 1 to 1 1/2 qt per acre of generic RU. You need to know how much ground your 25 gallon sprayer covers. Fill it with water & spray till it's empty. An acre is approx 200'x200' (round math)

    That is about what I am getting as far as gallons per acre . My thing is ,,,,,,,,,,, I can't remember the amount of chemical per gallon . Beanpile and I were filling the tank yesterday and we ended up putting about two quarts in . That stuff is expensive and I am a skinflint .

    Ratio of chemical/water is not important. It's the amount of chemical/acre that's important. If you're getting an acre per tankful, then one to one & a half quarts per tank will suffice. If the weeds are small still, a qt per acre will work, if they're bigger, then more chemical.

    a 2% mix of roundup, honcho, or any of the several other brands...will work fine..( read the ingredients)...128 ounces in a gallon..1.28= 1%...2.56 ounces =2%...to see how much per acre you will need to calibrate your sprayer. I have a formula at work...but don`t use it enough to remember it exactly...
