Changes in labels and ingredient statements.

1. Any change in the substance in the label or ingredient statement of a registered pesticide must be submitted in advance to the Director. 2. The registrant must describe the exact change desired, the proposed effective date and any other pertinent information that justifies the change. 3. After the effective date of a change in the label or ingredient statement, the product must be marketed under the new claims or ingredient statement, except that the Director may allow a reasonable time for disposal of properly labeled stocks of the old product.
