When must a certified applicator supervise a non-certified applicator?

A certified applicator must supervise a non-certified applicator when such presence is required by the pesticide label. This is crucial because pesticide labels contain specific instructions regarding the safe and effective use of the pesticide, including any required supervision. The label acts as a legal document and source of information that ensures compliance with application practices, safety precautions, and environmental protections. Adhering to these label requirements helps minimize risks associated with pesticide applications, including potential misuse or mishandling.

While it may seem reasonable to assume supervision is always required, or only in certain circumstances, the pesticide label is the definitive guide that outlines when supervision is necessary to ensure safety and compliance. The label requirements serve to protect both the applicator and the environment, reinforcing the importance of following precise directions.
