The pesticide restricted entry interval (REI) tells you:

The pesticide restricted entry interval (REI) tells you:

• A. Time elapsed before harvest
• B. From what corner of the field you enter
• C. How long the pesticide spray is active on pests
• D. How much time must pass before workers can reenter a treated area

Answer: (D)

The restricted-entry interval tells you the waiting period after a pesticide is applied before workers can reenter the treated area. This safety window is set on the label to limit workers’ exposure to pesticide residues on surfaces or in the air, protecting health during the days or hours after application. It’s not about harvest timing, entry location in the field, or how long the pesticide remains effective against pests. If a label lists an REI of, say, 24 hours, workers should wait that long before entering the area unless the label specifies otherwise or PPE requirements allow entry under certain conditions. The other options mix up purposes: PHI relates to when a crop can be harvested, not entry timing; field corner of entry has no relevance to safety intervals; and the duration the pesticide remains active on pests isn’t what REI measures.
