We are pleased to announce the 2023 PPCDL-Advanced Diagnostic Workshops hosted by the Scientists of the Plant Pathogen Confirmatory Diagnostic Laboratory (PPCDL) in Laurel, Maryland.

After a 2-year pause, we have planned for the return of in-person workshops. The planning team has developed a schedule that offers a wide variety of topics and delivery methods…nine topics in all…and both in-person and virtual workshops.

Visit the 2023 PPCDL/Beltsville Workshops Page for course schedule, information, and registration.
