How often must an applicator monitor a chemigation?

The requirement for monitoring chemigation at the beginning and near the end stems from the critical nature of these phases in ensuring safety and effectiveness. Monitoring at the beginning allows the applicator to verify that the chemigation system is functioning correctly, ensuring that chemicals are being delivered properly and at the right rates. Monitoring near the end is essential for checking that the intended application has been completed, and for assessing any potential issues that may have arisen during the process, such as leaks or unintended overspray.

Continuous monitoring, while ideal in many situations, is not a strict requirement for every scenario. It may not always be feasible or necessary depending on the specific application and the systems in use. The same applies to less frequent monitoring, such as only checking at the end or at hourly intervals, which could overlook critical moments when adjustments are needed.

Ultimately, monitoring at the specified times helps maintain effective chemigation practices while ensuring adherence to safety protocols and reducing the risk of environmental contamination.
