Trying to solve a problem from work, how much roundup was used: the information I have to work with is a total of 1450 gallons of roundup and water was used, mix rate of 3 ounces per gallon (2.3%), applied at 2 2/3 ounces per 1000 square feet. this roundup has an active ingredient percent of 41.0%. Roundup says not to use more than 7 quarts of this product per acre per year. this is how I solved it. n= 1450 (gal.) x 2.3 (%a.i.) x 8.3 (lbs water) = 27685.5 divided that by 41.0 (% a.i.) x 100 or 4100 = 6.75 gallons of active ingredient used. I can get the square feet of where it was sprayed to see if I am below 7 quarts. My question is did I get the active ingredient right.
