Next week while I am attending the American Phytopathological Society Annual Meeting and International Congress of Plant Pathology, the Plant and Pest Diagnostic Clinic will be operating at partial capacity until Monday, Aug 6. 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 until the samples can be read.
The following diseases were reported in samples submitted to the UNL Plant and Pest Diagnostic Lab from July 16 – July 26.
