How often should calibration of application equipment be performed?

Calibration of application equipment is essential to ensure accurate and effective pesticide application. Regular calibration helps to maintain the precision of the application rate, which is crucial for both efficacy and safety. It allows applicators to apply the correct amount of pesticide, minimizing environmental impact and reducing the risk of pest resistance.

Performing calibration at least once a season or whenever there is a change in the type of pesticides being used ensures that any variations in the equipment or changes in the pesticide's formulation are accounted for. Seasonal calibration accommodates the potential for equipment changes due to wear and tear or adjustments made during off-seasons. Additionally, different pesticides may have distinct application requirements, including varying rates, pressures, or spray patterns, necessitating recalibration to ensure optimal performance.

This practice not only promotes responsible pesticide use but also aligns with regulatory standards and best management practices in turf and ornamental pest control. Regular calibration ultimately contributes to the sustainability of pest management efforts and helps ensure compliance with local and federal guidelines.
