You have calibrated your equipment to spray 50 gallons per acre. The label calls for three pounds of formulation per 100 gallons of water. How much formulation should you add to the tank in order to make 50 gallons of finished spray?

To determine the correct amount of formulation to add to the tank for a finished spray of 50 gallons, we can first analyze what the label indicates: three pounds of formulation is required for 100 gallons of water.

Since you are using 50 gallons of finished spray, which is half of 100 gallons, you will need half the amount of formulation specified for the larger volume. Therefore, you take three pounds and divide it by two.

This calculation results in 1.5 pounds of formulation needed. The application rate is designed so that for every 100 gallons, three pounds of the formulation must be mixed. By scaling this down appropriately for the volume you are using, you ensure that the concentration remains consistent and effective for application.

Following this rationale confirms that 1.5 pounds of formulation is necessary to create 50 gallons of finished spray. The understanding lies in recognizing how to proportionally adjust the rate based on the dilution specified on the label.
