What does REI stand for in pesticide application terminology?

REI stands for Re-entry Interval in pesticide application terminology. This term refers specifically to the time that must pass between the application of a pesticide and the time when it is safe for individuals to enter the treated area without protective equipment. The purpose of establishing a Re-entry Interval is to ensure the safety of workers and bystanders, minimizing their risk of exposure to potentially harmful residues of the pesticide.

Understanding the Re-entry Interval is crucial for anyone handling pesticides, as it directly impacts workplace safety and compliance with regulations. Each pesticide product will have its own specified REI on the label, which is determined based on the toxicity of the chemical and the potential risks associated with exposure. Adhering to these guidelines helps prevent health risks and improves the overall safety of agricultural and landscape operations.
