UW-Madison/Extension Plant Disease Diagnostic Clinic (PDDC) Update July 9, 2021
In 2021, the PDDC continues with limited hours and limited sample processing capacity due to COVID-19. Click here for the PDDC’s current submission policy. The PDDC is continuing to provide diagnoses through examination of digital photographs, although in 2021 there will be a fee for this service. As in 2020, digital diagnoses will be included in the Wisconsin Disease Almanac. For Almanac entries below, 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 July 3, 2021 through July 9, 2021.
PLANT/SAMPLE TYPE | DISEASE/DISORDER | PATHOGEN | COUNTY |
