Crop Diseases Confirmed by PPDC Sept. 27-Oct. 5

The Plant and Pest Diagnostic Clinic will be working at partial capacity October 12-19 due to my wedding out of state.  Plant samples may still be submitted, but turnaround time will be delayed.  All samples submitted to the clinic during this time will be stored under refrigerated conditions to maintain quality. I will return to the office October 19.  Thanks in advance for your patience.
