REI is an acronym used on pesticide labels to describe a ...

• A. A measure of long-term environmental risk
• B. A time period when entry is restricted after application
• C. A type of pesticide formulation
• D. A rating system for consumer safety

Answer: (B)

Restricted Entry Interval means the time after a pesticide is applied when entry to the treated area is restricted or prohibited to protect workers from exposure. The label specifies how many hours the REI lasts and any conditions for entry, such as required personal protective equipment. This concept is about safety timing after application, not about environmental risk, formulation type, or consumer safety ratings. After the REI expires, entry can resume under the label’s specified conditions.
