January 2022: Plant Disease Diagnostics Clinic Services for 2022

Turquoise Microscope IconAs we start 2022, COVID-19 continues to inform how the UW Plant Disease Diagnostics Clinic (PDDC) provides services to the public.  Clinic personnel continue to try to balance providing high quality services to the public with keeping clinic staff and clients healthy and safe.  The following are current guidelines for submitting samples and tapping into the PDDC’s outreach programs and resources.  Given that the COVID-19 situation is ever evolving, there will likely be changes in these guidelines as the year progresses.  Be sure to check this document routinely for updates.

Plant Disease Diagnostics

In 2020, I started offering formal digital diagnoses, and that service will continue in 2022.  I really encourage you to submit digital photos of your plant disease problems before submitting physical samples.  Use the online form at https://pddc.wisc.edu/digital-diagnosis/.  If I can see enough of what’s going on in your photos, I will provide you a diagnosis with management recommendations and charge the $20 digital diagnosis fee.  If I cannot make a definitive diagnosis, I will not charge the fee, but I will use the photos to help me provide you with suggestions on what sort of physical sample to submit as a follow-up.  Note that if I charge the digital fee and you end up submitting a follow-up physical sample, the digital fee will be credited towards any lab fees for your physical sample.

You can submit physical samples for diagnosis either by mail or in person.  For increased safety, I suggest submitting by mail.  If you opt to drop off a sample in person, PDDC staff will not be available for an in-person consultation.  While I am committed to providing personalized service to my clients, continuing issues with COVID-19 suggest that limiting person-to-person contact is prudent.  Also note that wearing a mask is required in all UW-Madison buildings at this time.

The PDDC provides a sample drop off location in the hall outside the clinic.  Check for the large, black, wood shelving unit in the alcove just down the hall from the clinic door.  You can drop your sample(s) there.  Be sure to fill out a submission form to include with your sample.  You can find forms in the wall pocket to the left of the clinic door.  The form is also available online if you would like to fill it out ahead of time to speed up the submission process.  Please print neatly and make sure to include your complete mailing address, your phone number and your email address.  At this time, I am emailing virtually all reports and invoices.  If you do not have email however, I definitely can send out a hard copy of your report and invoice.


I was hoping to start providing in-person PDDC presentations in 2022, but with COVID-19 cases increasing at this time, I have cancelled the few in-person talks that I already had scheduled in early 2022 and will be limiting presentations to virtual presentations (e.g., via Zoom) until further notice.  If you are interested in having me provide a presentation, click here to check out a list of topics that I routinely speak on.  Email me at pddc@wisc.edu or call me at (608) 262-2863 to discuss what talk might be best suited for your audience.

Online Resources

Via the PDDC website, I will continue to provide weekly updates of my PDDC diagnoses (the Wisconsin Disease Almanac), as well as web articles (hopefully monthly, but frequency will depend on clinic sample volume).  Also check out the revised and rebranded UW Plant Disease Facts (formerly the plant disease-related titles of the University of Wisconsin Garden Facts).  I am also working on converting some of my in-person talks [Fundamentals of Plant Diseases and The Science (and Art) of Plant Disease Diagnosis] into online training modules with voiceovers.  As these new resources become available, I will announce their availability via Twitter, Facebook (@UWPDDC), or via my clinic listserv, UWPDDCLearn (email me to subscribe to this).


As always, if you have questions about plant diseases, feel free to contact me by phone at (608) 262-2863 or email at pddc@wisc.edu.

Stay safe everyone and all the best for 2022!
