Off the top of my head with the 4 gallon backpack sprayer I am using 1 oz per gallon is that right?
So basically chemical mowing is 1/2 of that amount? You know I'll have to get back and check sometime tomorrow I don't know if that scoop constitutes an oz. or not. Basically the roundup lid can fit 3 scoops and we add a 4th or something to that effect.
