What should you mark on each pesticide container to help prevent deterioration?

• A. Expiration date
• B. Batch number
• C. Pesticide concentration
• D. Date of purchase

Answer: (D)

Tracking how long a pesticide has been in storage helps prevent using degraded products. Marking the date of purchase on each container provides a clear reference for stock rotation, so older lots are used first and aren’t kept past their usable life. This makes it easier to replace or retire inventory before deterioration reduces effectiveness, even in cases where an explicit expiration date isn’t provided.
