What is one of the requirements for supplemental labeling?

Supplemental labeling is an important aspect of pesticide regulation, as it provides additional information to users without needing to modify the primary product label. One of the key requirements for supplemental labeling is that it must refer users to the primary product label. This ensures that users have access to all the necessary details and safety information contained in the primary label, which is crucial for the safe and effective use of the pesticide.

By directing users to the primary label, supplemental labeling helps to ensure consistency and compliance with regulatory standards, allowing users to make informed decisions about the application of the pesticide. This requirement also reinforces the importance of the primary label as the main source of information regarding product use, safety precautions, and legal requirements, while the supplemental label serves to provide additional context or clarify certain aspects related to the product.
