Per the Prime Source Flumioxazin 51 WDG Select Herbicide label, for pre-emergence application, use 10-30 gallons of spray solution per acre for uniform coverage. When making backpack applications, apply 50-100 gallons of spray solution per acre.
For post emergent application the label states, "to ensure thorough coverage when using boom sprayers, apply 15 - 30 gals. of spray solution per acre. Apply 20 - 30 gals. per acre when using a boom sprayer if dense vegetation or heavy residue is present on the soil surface. When applying with a backpack sprayer, apply 1 gal. of spray solution per 500 - 1,000 sq. ft. Ensure nozzle selection meets manufacturer's gallonage and pressure specifications for post-emergence herbicide application."
See label for complete instructions.
