To treat each of the 5 acres, you would need 130 gallons of water for each acre. ** 1 acre = 130 gallons of water (3 gal of water x 43,560 sq ft (sq ft in acre)
You would need to refill your sprayer approx 3 times to thoroughly treat 1 acre.
Depending on what weeds you are targeting, you will divide the 19 fl oz, 24 fl oz or 34 fl oz mix rate per acre and divide by 3 (the # of times you will fill the 40 gal sprayer) .
Low Rate 19 fl oz / 3 tank fills = 6.3 fl oz per tank
Mid Rate 24 fl oz / 3 tank fills = 8 fl oz per tank
High Rate 34 fl oz / 3 tank fills + 11.3 fl oz per tank
