Is calibration of granular pesticide application equipment necessary for certified applicators?

Calibration of granular pesticide application equipment is indeed a critical practice that certified applicators should prioritize to ensure the effective and safe application of pesticides. The correct approach to understanding this requirement starts with recognizing that while manufacturers may perform initial setup and factory testing, this does not eliminate the need for ongoing calibration by the user.

Regular calibration is essential as it ensures that the equipment delivers the correct amount of pesticide to achieve the desired control of pests while minimizing environmental impact and avoiding harm to non-target organisms. Factors such as variations in application conditions, wear and tear on equipment, and changes in formulation can all affect performance over time.

Relying solely on factory calibration could lead to inaccurate applications, resulting in either ineffective pest control or environmental contamination. Therefore, regardless of whether the equipment is new or previously used, certified applicators must regularly check and calibrate their equipment to maintain its precision and reliability. This is part of maintaining best practices in pesticide application for safety and efficacy.
