Here's what I do - \

The directions call for 20 oz per acre. It doesn't really matter if you mix that 20 oz with 20 gallons, 30 gallons, or 40gallons of waterand apply it one on 1 acre.

My sprayer puts out about 20 gallons of water per acre when I'm in 2nd gear. So I mix 20 oz with 20 gallons water - for one acre. If I'm spraying 3 acres - then 60 gallons water and 60 oz of 41% GLYPHOSATE.

In other words - the mixture isn't as important as knowing how much your sprayer puts out per acre.
