Which of the following best describes the purpose of including crop/seed restrictions on a treated seed label?

• A. To determine when to harvest.
• B. To prevent use on incompatible crops or seed types.
• C. To indicate seed color.
• D. To speed up coating.

Answer: (B)

Crop/seed restrictions are there to ensure treated seed is used only on crops and seed types that have data and authorization on the label. Different crops and seed types can react very differently to the same treatment, so applying a treated seed to an unsupported crop can cause crop injury, reduced germination, or ineffective pest protection. The restrictions spell out exactly which crops and seed types are compatible, helping prevent harm and keep you in compliance with the product’s registration. They aren’t about when to harvest, seed color, or how fast the coating goes on—those aspects aren’t related to why the label limits usage to certain crops and seed types.
