The Beltsville Advanced Diagnostic Workshops are hosted by a collaboration between the NPDN and the Plant Pathogen Confirmatory Diagnostics Laboratory (PPCDL) in Laurel, MD.

Since 2003, groups of NPDN members and partners have gathered annually in Maryland for this most valued diagnostic training opportunity. Just like so many other aspects of our lives from 2020 to 2022, these workshops had to adapt due to the COVID-19 pandemic and associated restrictions and were delivered virtually.

The modules change from year to year depending on the current pest issues and needs. Find a list of all workshop topics with descriptions here: all workshop descriptions

Participants must be present for the entire workshop. If you cannot attend every day and all sessions, please plan to take the workshop at another time. You need to give yourself at least 3 hours of time from workshop completion to your outgoing flight. Participants must complete any assigned homework, tests and hands-on activities during the time period indicated, to receive a certificate of course completion.
