The Plant Diagnostic Clinic at the University of Delaware accepts plant samples showing signs or symptoms of disease. The Clinic is housed in the Department of Plant and Soil Sciences at the University of Delaware in Newark , and operates as a function of Delaware Cooperative Extension.
The UD Plant Diagnostic Clinic is a part of the Northeast Plant Diagnostic Network (NEPDN). The Northeast Plant Diagnostic Network is a group of 12 Land Grant Universities that is part of the National Plant Diagnostic Network (NPDN). The mission of the network is to enhance national agricultural security by quickly detecting introduced pests and pathogens. This system links diagnostic laboratories with common strategies and tools, and increases communication among pathologists and the public.
A Plant Diagnostic Clinic Form should accompany any sample, with information filled in as completely as possible. A copy of the sample submission form may be downloaded and printed from this site. Many homeowner samples may not need to be sent to the Clinic, but may be diagnosed by Master Gardeners or County Agents in the county offices. The Nematode Assay Service is also a part of the UD Plant Diagnostic Clinic. This fee based service provides identification and enumeration of plant parasitic nematodes in soil and plant tissue (requires Nematode Assay Information Sheet).
