How to Use This Calculator
  1. Enter the pesticide product and label rate in oz, fl oz, or lb per acre.
  2. Set the field size in acres and sprayer tank capacity in gallons.
  3. Input target carrier volume per acre (GPA).
  4. Review the product amount per tank and total product needed.
  5. Double-check label rate and maximum seasonal application limit before mixing.

What each input means

Desired Spray Rate
Target spray volume per acre in gallons. Typical field crops: 10-20 gal/acre.
Field Size
Total field area to spray in acres.
Nozzle Flow Rate
Flow rate per nozzle in gallons per minute at operating pressure. Check nozzle catalog.
Travel Speed
Ground speed of the sprayer in miles per hour.
Nozzle Spacing
Distance between nozzles on the boom in inches. Common: 15 or 20 inches.
Product Rate
Pesticide application rate in fluid ounces per acre from the product label.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Desired Spray Rate = 15, Field Size = 160, Nozzle Flow Rate = 0.4, Travel Speed = 10 = 6 input(s) provided
  2. Calculate Total Spray Mix Needed
    Total Spray Mix Needed
    2400 = 2400
  3. Calculate Total Product Needed
    Total Product Needed
    3840 = 3840
  4. Calculate Total Product
    Total Product
    30 = 30
