What is a Master Label?

The Master Label contains all of the approved uses for a given pesticide product and all associated labeling. Master Labels must be submitted for EPA approval. EPA-approved Master Labels are stamped “ACCEPTED” and placed in the official record. Labeling for a given product must not contain any text beyond that which is approved in the Master Label, except for supplemental labeling. The Master Label provides critical information about how to handle and use the pesticide product.
