Which factor should you consult to verify the exact REI for a product?

• A. The Agricultural Use Requirements box
• B. The weather forecast
• C. The pesticide brochure in the office
• D. The daily market price

Answer: (A)

REI stands for Restricted Entry Interval—the legally required waiting period after pesticide application before workers can reenter a treated area without special PPE. The exact REI for a product isn’t a guess or something you derive from the weather or market news; it’s specified on the product label, specifically in the Agricultural Use Requirements box. That box contains the entry restrictions and PPE requirements for that particular product and use, and REI can vary between products and even between uses of the same product. So checking that box on the label is the only reliable way to verify the exact REI. The weather forecast, an office brochure, or market prices don’t determine or authorize entry restrictions.
