Dilution Calculator
Work out how much concentrate and water you need for a given mix ratio and total spray volume, with unit conversions between liters, gallons, milliliters and fluid ounces.
Application Rate Calculator
Enter the area, spray volume and label rate to estimate total product required, product per tank, number of tank loads and approximate product cost.
Before you use a calculator
- Calibrate your sprayer first; the calculators assume your actual output matches the spray volume you enter. See the calibration guide.
- Use the rate and units printed on your product label. Check whether the rate is expressed as product or as active ingredient.
- Double-check every result by hand. These tools do not know your product, crop or local regulations.
