If there is a conflict between the regulation-specified REI and the labeling-specified REI, which should be followed?

In situations where there is a conflict between the regulation-specified Restricted Entry Interval (REI) and the labeling-specified REI, the longer REI should be followed. This is important because the REI is a critical safety measure designed to protect workers from pesticide exposure after application.

The reasoning behind adhering to the longer REI is rooted in the principle of prioritizing safety over convenience. Pesticides can have varying levels of toxicity, and the longer REI allows for adequate time for the pesticide residues to diminish, thereby reducing the risk of harmful exposure to agricultural workers. Regulations are typically established based on extensive research and data to ensure that the safety of individuals handling or entering treated areas is not compromised.

By following the longer REI, those responsible for pesticide application ensure that they comply with the most protective standard available, promoting workplace safety and adhering to best practices in pesticide use and enforcement. This approach underscores the importance of regulatory compliance in ensuring both worker health and environmental safety.
