In which context is calibration typically performed?

Calibration is primarily performed to ensure proper pesticide application rates. This process involves adjusting the equipment and understanding the application techniques to deliver the correct amount of pesticide required for effective control of the target pest while minimizing environmental impact. Accurate calibration helps prevent over-application, which can lead to excessive pesticide residues in the environment, potential harm to non-target species, and increased costs for the applicator. This is critical in aquatic environments where the sensitivity to chemical applications is heightened due to the presence of water organisms and ecosystems.

In contrast, tracking pesticide residue levels focuses on post-application assessments rather than the calibration process itself. Evaluating the efficiency of pest control methods is concerned with measuring the effectiveness of the actions taken rather than ensuring the correct application rates. Measuring soil moisture levels prior to application pertains more to determining optimal conditions for application rather than the calibration of the application equipment itself. Each of these other contexts serves an important role in integrated pest management but does not directly relate to the core purpose of calibration.
