What does the "restricted entry interval" on a pesticide label indicate?

The "restricted entry interval" (REI) on a pesticide label indicates the waiting period before individuals are allowed to re-enter a treated area where a pesticide has been applied. This timeframe is established to protect workers and bystanders from potential exposure to harmful residues. During the REI, the pesticide may still be active, and entering the area could pose health risks.

This precaution ensures that any hazardous effects of the pesticide diminish before people return to that space, thus enhancing safety during agricultural operations. Understanding the REI is crucial for enforcing safety protocols in pesticide application and for maintaining compliance with regulatory standards.
