Extension Programs

We bring the benefits of plant science to the public.

Penn State Extension shares the resources of the Department of Plant Science with Pennsylvania and beyond through the dissemination of current, accurate, and research-based plant science information.

Faculty members with extension appointments are the primary delivery sources for outreach programs; however, all faculty members leverage their teaching and research programs to serve people, businesses, and institutions.
