Your calibrated sprayer covers 4.0 acres. How many pounds of pesticide are needed for a label rate of 1.5 pounds per acre?

To determine the amount of pesticide needed based on the calibrated sprayer's coverage and the label rate, you need to multiply the area covered by the label rate per acre.

In this case, the sprayer covers 4 acres, and the label rate is 1.5 pounds per acre. The calculation would look like this:

1. Multiply the area (4 acres) by the rate (1.5 pounds per acre): 4 acres × 1.5 pounds/acre = 6 pounds.

This calculation shows that to treat 4 acres at the specified label rate, a total of 6 pounds of pesticide is required. This reflects the application rate and ensures that you're following the label guidelines, which is crucial for effective pest control and environmental safety. Thus, the answer of 6 pounds is correct because it directly corresponds to the total required for the area being treated.
