What does the restricted-entry interval (REI) on a pesticide label specify?

• A. The time between pesticide applications
• B. The time before pesticide residues become phytotoxic
• C. The time before a pesticide-treated area is safe to enter without wearing PPE
• D. The time between the time of pesticide application and harvest of the treated crop

Answer: (C)

The main idea is safety after a pesticide is applied. The restricted-entry interval is the waiting period after spraying during which entering the treated area is restricted to protect workers from exposure. During this time, you typically must wear the label-recommended PPE if you must enter. Once the interval ends, it’s considered safe to enter without PPE for most tasks, though you still must follow the label’s directions for any specific requirements. This is not about how long between applications, residues causing phytotoxicity, or the harvest interval.
