What is the formula for converting an active ingredient (a.i.) formula to gallons using a liquid formula?

The appropriate formula for converting an active ingredient (a.i.) formula to gallons using a liquid formula is derived by understanding the relationship between the amount of active ingredient needed per acre and the concentration of that ingredient in the product.

When using the formula represented in the correct choice, it compares the amount of active ingredient required per acre to the amount of active ingredient present in the product measured in gallons. By dividing the number of pounds of active ingredient required per acre by the number of pounds of active ingredient contained in each gallon of the product, you arrive at the number of gallons needed to achieve the required application rate.

This method ensures that you are accurately calculating the volume of product you need based on the strength of the active ingredient and the application area, which is essential for proper pesticide application in compliance with safety and regulatory standards.
