Which of the following factors should be considered when calibrating application equipment?

When calibrating application equipment, the required application rate is crucial because it dictates how much pesticide needs to be delivered per area. Understanding this rate ensures that the proper amount of chemical is applied for effective pest control while avoiding over-application, which can lead to environmental harm and pesticide resistance. Accurate calibration to meet the required application rate helps in achieving the desired efficacy of the pesticide while also adhering to safety and regulatory guidelines. This focus directly impacts the success of pest management strategies and preserves both crop health and environmental integrity. The other factors, while important for overall pest management, specifically relate to additional operational considerations rather than the primary function of calibration itself.
