Which statement describes a supplemental pesticide label?

A supplemental pesticide label is a specific type of document that provides additional information about the use and restrictions of a pesticide beyond what is stated on the main label. This can include specific directions for application, safety precautions, or special use limitations that are important for the proper and safe use of the product. The correct answer captures the essence of this definition by indicating that it is a pamphlet that contains important use directions and pesticide restrictions attached to the container, thereby ensuring that the applicator has the necessary information to use the pesticide effectively and safely.

In this context, understanding that supplemental labels are official documents that complement the main label helps ensure compliance with regulations and promotes responsible pesticide use. A supplemental label is not merely sales literature or a sample; it is a crucial piece of documentation designed to inform users about additional regulations or guidelines essential for correct application.
