During 2016, the Plant Diagnostic Clinic processed approximately 656 non-survey routine clinic samples. Nursery surveys for Delaware Department of Agriculture resulted in a few samples of boxwood and gardenia. Other samples were diagnosed in field situations, and not brought in for analysis. Phone inquiries and e-mail requests for information were replied to in addition to physical specimens submitted to the lab. Most samples were from Delaware. Crop sources for those were, in order of predominance: Ornamentals (55 %), Vegetables (22%), Field Crops (10%), Fruit, Turf, Insect ID, Fungal ID, and Christmas trees.
