Based on a withdrawal rate of 0.023 gpm and an application rate, what is the herbicide application rate in gallons per acre?

The herbicide application rate in gallons per acre is based on the relationship between the volume of herbicide being applied and the area being treated. Given a withdrawal rate of 0.023 gallons per minute (gpm), it's important to consider how this translates into an acre application rate over a specific time frame.

An acre is defined as 43,560 square feet. If we assume the application occurs continuously over a certain duration, we can calculate the gallons per acre by understanding how many gallons are utilized to treat that entire area.

In this case, if 0.023 gpm is the flow rate, you would convert this to a rate per acre using the appropriate time or area factor. The calculations would result in an application rate of 1.0 gallons per acre (gpa).

This figure corresponds to the desired application rate needed to ensure effective herbicide coverage across one acre of land. It aligns with the agricultural practices that suggest this rate for optimal pest control without over-application. The other choices represent different application rates that would not be consistent with the provided withdrawal rate and would either under- or over-apply the herbicide relative to the area coverage.
