Which term best matches the definition of REI?

• A. Re-entry interval
• B. Re-emergence Instance
• C. A sporting goods store
• D. Residue

Answer: (A)

REI refers to the time after pesticide application when entry into the treated area is restricted to protect people from exposure. The best match is the Re-entry interval, which the product label specifies in hours and outlines what level of PPE is required if entry is necessary during that period. It’s not about an unrelated term like re-emergence, nor about a sporting goods store, nor about residue left behind. So the Re-entry interval is the correct concept.
