What is the primary purpose of post-application signs in an area where a restricted-entry interval is in effect?

• A. To indicate the product is in stock.
• B. To inform workers about where to perform entry.
• C. To advertise pesticide sales.
• D. To warn that entry is restricted and when the interval ends per label.

Answer: (D)

Post-application signs are a safety measure that informs workers and others that the area has an entry restriction after pesticide application and when it is safe to re-enter according to the label. They communicate the restricted-entry interval (REI) and the end time specified by the product label, helping prevent exposure to residues during that period. These signs aren’t about stock, sales, or where entry occurs; their purpose is to convey timing and safety information tied to the pesticide’s label.
