RE: round up application
Depending on what brand of Glyphosate you are using, Roundup Weather Max or Original Max-22 0z. per acre. Generic Glyphosate-32 oz. per acre minimum. I add 3 oz. per gallon for spot spraying. You need to calibrate your sprayer. If you have never done this, I can help. Just let me know how wide the nozzles are from each other and we can go from there. If that is too much work, just fill your tank with about 15 gallons and see how far this gets you. Hopefully it will cover an acre. Application rates vary from 10 to 20 gallons of water per acre.
