In the context of spray mixture calculations, sprayer output is measured as what unit?

• A. ounces per square foot
• B. gallons per acre
• C. pounds per gallon
• D. liters per hectare

Answer: (A)

Sprayer output is about how much spray lands on a defined area, so the unit should express volume per area. In ornamental settings, expressing this as ounces per square foot directly ties the amount of spray to the surface area being treated. It lets you calculate total spray needed easily: multiply the ounces per square foot by the area in square feet to get total ounces, then convert to gallons if needed. This is especially practical for benches, pots, and small plots where coverage on plant surfaces matters.

Other units, like gallons per acre or liters per hectare, are useful for large-field applications and planning overall coverage, while pounds per gallon describes concentration of the active ingredient in the mix, not how much spray is delivered per area.
