How to Use This Calculator

Enter the herbicide label rate in fluid ounces per acre and your sprayer tank capacity in gallons.
Set the field size to spray in acres.
Input the carrier (water) volume applied per acre, typically 10-20 gal/acre for field crops.
Enter the surfactant rate as a percentage by volume (typically 0.25% for non-ionic surfactants).
Review product needed per tank and for the whole field, tank loads required, acres covered per tank, and surfactant volume.

How the result changes with Carrier Volume

Tank Size: Spray tank capacity in gallons.
Product Rate: Herbicide application rate in fluid ounces per acre from the product label.
Acres to Spray: Total field area to be sprayed.
Carrier Volume: Total spray solution (water + product) applied per acre. Typical: 10-20 gal/acre for field crops.
Surfactant Rate: Surfactant (adjuvant) percentage by volume. Typically 0.25% v/v for non-ionic surfactants.
