How often should calibration of application equipment be performed?

Calibration of application equipment is crucial for ensuring accurate pesticide application rates and effectiveness. Performing calibration regularly, at least once per season, allows applicators to account for variables such as equipment wear, changes in pesticide formulations, and environmental factors that can affect application performance. Regular calibration helps maintain consistent performance and ensures compliance with label requirements, ultimately reducing the risk of environmental contamination and improving pest management efficacy.

While calibrating after every use may seem effective, it can be impractical for many applicators, potentially leading to unnecessary delays. Conducting calibration once a year would not be sufficient, as it may overlook potential changes throughout the season that can impact application accuracy. Lastly, stating that calibration is not necessary disregards the importance of precise application to both safety and efficacy in pest management practices.
