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 August 20, 2022 through August 26, 2022.

PLANT/SAMPLE TYPE	DISEASE/DISORDER	PATHOGEN	COUNTY
FRUIT CROPS
Cranberry	Upright Dieback	Phomopsis vaccinia	Wood
