UW-Madison/Extension Plant Disease Diagnostic Clinic (PDDC) Update September 30, 2022
In 2022, the PDDC continues to provide diagnoses through examination of digital photographs, as well as physical samples. Click here for the PDDC’s current submission policy, as well as information on the PDDC’s current fee structure. Digital diagnoses will be included in the Wisconsin Disease Almanac and when a digital diagnosis would normally require a lab confirmation, the disease/disorder will be labeled as “suspected”. The following diseases/disorders have been identified at the PDDC from September 24, 2022 through September 30, 2022.
