I have even tried as low as 3 GPA wiht good results. The check valves on the nozzles were slow to open. I pretty much use 5 gpa, but will decrease if I can save a extra fill on my aprayer.
AI 8002 with 1 Qt Reguest and 1 Qt Dynamic (both from Helena) per 100 gals H2O.
In my opionion less is better with Roundup (or generics like I currently use).
