The final report for the UD Plant Diagnostic Clinic for 2015 has been posted and can be viewed at the following link:
The Plant Diagnostic Clinic at the University of Delaware is housed in the Department of Plant and Soil Sciences, and is located in Townsend Hall, Room 151. The clinic serves the public through Delaware Cooperative Extension, directly serving commercial growers, crop consultants, nurserymen, landscapers, public gardens, and private homeowners. Samples are also received through county offices, from Extension specialists, and the Master Gardener Program. The clinic is the National Plant Diagnostic Network (NPDN) laboratory for Delaware, and the survey laboratory for Delaware Department of Agriculture and USDA/APHIS CAPS for Delaware. The clinic operates with one full-time staff, the Plant Diagnostician, cooperating with the Extension Plant Pathologist and the Ornamentals IPM Specialist in Entomology, and numerous Extension personnel.
During 2015, the Plant Diagnostic Clinic processed approximately 630 non-survey routine clinic samples. A National USDA/APHIS PPQ CAPS karnal bunt survey in cooperation with Delaware Department of Agriculture for wheat seed samples from all grain elevator processing stations in Delaware included five composite aliquot samples. All samples examined for the presence of karnal bunt were negative, ensuring the safety of the Delaware wheat crop for trade and export. Nursery surveys for Delaware Department of Agriculture resulted in a few samples of boxwood and chrysanthemum. Other samples were diagnosed in field situations, and not brought in for analysis. Phone inquiries and e-mail requests for information accounted for undocumented samples in addition to physical specimens submitted to the lab. The Ask an Expert service through eXtension.org included 69 questions answered by the Diagnostician in 2015. Over 50 % of the total questions answered via Ask an Expert for Delaware involved trouble-shooting of possible disease issues. Some trouble-shooting samples for possible nematode infections were processed in the lab, but are not included in this report…. see link for full report and data.
