The calibration of application equipment is done to ensure that the intended amount of pesticide is delivered to the target area.

• A. True
• B. False
• C. Only For High Volume Applications
• D. Only When Using New Products

Answer: (A)

Calibration focuses on making sure the sprayer actually delivers the amount of pesticide that the label calls for to the target area. By checking how much product comes out of the nozzles under the expected operating conditions (how fast you’re moving, the nozzle type and size, the pressure, and boom height) and then adjusting those factors, you align the output with the intended rate per area. This accuracy is essential for effective pest control, cost efficiency, and reducing environmental risk, and it isn’t only needed for high-volume applications or when using new products. Even with familiar products, wear, temperature, or changes in speed or pressure can shift output, so calibration should be routine whenever you set up the equipment or conditions change.
