What does the term "REI" stand for on a pesticide label?

The term "REI" stands for "Restricted Entry Interval." This concept is crucial for ensuring the safety of individuals who may enter an area where pesticides have been applied. The REI is the period of time that must elapse between the application of a pesticide and the time that unprotected people, including workers and bystanders, are allowed to enter the treated area. This interval is intended to minimize the risk of exposure to potentially harmful pesticide residues that might still be present in the environment immediately following application.

Understanding the REI is essential for compliance with safety regulations and for protecting the health of individuals who work in agricultural settings or near treated areas. Proper adherence to these intervals promotes safe pesticide use and helps prevent pesticide-related illnesses.

Other terms listed do not accurately reflect the established definition or function of REI in the context of pesticide safety.
