How to Use This Calculator

Enter the insecticide product and target pest.
Set the label rate in oz or lb per acre.
Input field size in acres and sprayer tank capacity in gallons.
Review total product needed and per-tank amount to load.
Verify PHI (pre-harvest interval) and REI (re-entry interval) before application.

How the result changes with Label rate (fl oz/acre)

Label rate (fl oz/acre): Recommended application rate from the product label.
AI concentration (%): Active ingredient percentage shown on the label (e.g., 41.1% for chlorpyrifos).
Field size (acres): Total area to be treated.
Spray volume (GPA): Gallons of total spray mix applied per acre.
Cost per container ($): Price per container/jug of product.
Container size (fl oz): Volume of each product container (128 oz = 1 gallon).

Total product needed (fl oz): Total fluid ounces of product required for the field.
Containers to purchase: Number of containers needed (rounded up).
AI applied (lb/acre): Pounds of active ingredient applied per acre.
Total spray mix (gal): Total gallons of spray solution for the field.
Product per gal spray mix: Ounces of product to add per gallon of water in the tank.
Product cost ($/acre): Product cost per acre (based on whole containers).
