In case of a discrepancy between the regulation-specified REI and the label-specified REI, which should be followed?

In situations where there is a discrepancy between the regulation-specified Restricted Entry Interval (REI) and the label-specified REI, the proper course of action is to follow the longer interval. This practice ensures the safety of workers and others potentially exposed to pesticide applications.

The rationale behind using the longer interval stems from the understanding that regulations are generally designed with public health and safety in mind, and they often take into account the most conservative guidelines. Label instructions are also important, but in scenarios where exposure might be a concern, adhering to the longer REI minimizes the risk of adverse effects. Thus, prioritizing the longer interval helps provide a buffer period that increases safety for those re-entering treated areas.

By implementing this approach, professionals demonstrate diligence in adhering to health guidelines and regulations governing pesticide use.
