Mission
The University of Wisconsin-Madison/Extension Plant Disease Diagnostics Clinic (PDDC) provides assistance in identifying plant diseases and provides educational information on plant diseases and their control.
PDDC clients include agricultural and horticultural producers (e.g., farmers, nursery owners), agricultural and horticultural professionals (e.g., crop consultants, arborists), home gardeners, Extension staff and Master Gardener volunteers, and state and local government (e.g., Wisconsin DNR, city and county foresters).
While the Plant Disease Diagnostics Clinic focuses on plant disease problems in the state of Wisconsin, any interested party is welcome and encouraged to take advantage of and participate in the Clinic’s educational services and activities.
If after exploring this website, you have questions about PDDC services feel free to contact the clinic at 608-262-2863 or bdh@plantpath.wisc.edu.
