In 2023, 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 23, 2023 through September 29, 2023.

PLANT/SAMPLE TYPE	DISEASE/DISORDER	PATHOGEN	COUNTY
FRUIT CROPS
Apple	Blister Canker	Biscogniauxia marginata	Iowa
