Details, formula, and sources
ScopeAcres treated per tank (tank gal / GPA), product per tank in the entered unit with gal / mL or lb / g conversions, and tanks / total product / carrier water for a field. Tank-mix math first-principles; the EPA label is the law (FIFRA).
Formula or tableAcres per tank = tank capacity (gal) / spray volume (GPA). Product per tank = acres per tank x product rate per acre. Tanks needed = ceil(field acres / acres per tank). Total product = field acres x rate. Total carrier water = field acres x GPA.
Source and editionEPA pesticide label (the label is the law per FIFRA) and NRCS Agronomy Technical Note 5 (spray calibration) by name.
