What must be included on pesticide products that might adversely affect an endangered species?

The correct option highlights the importance of awareness regarding the potential impact of pesticide use on endangered species. Including a label statement that advises applicators to consult a county bulletin ensures that users have access to the most current and relevant information regarding local environmental conditions and regulations. This is critical because these bulletins often provide specific guidelines on the precautions that should be taken to minimize harm to endangered species in nearby areas.

Specifically, these bulletins may include information on the presence of endangered species in the vicinity, seasons when certain species are more vulnerable, and any special restrictions or recommendations that have been implemented in the area to protect these species. By highlighting the need for prevention strategies through consultation, this approach fosters more responsible pesticide application practices and enhances the protection of biodiversity.
