Welcome to the National Plant Diagnostic Network Website
The NPDN was established in 2002 in response to the need to enhance agricultural security through protecting health and productivity of plants in agricultural and natural ecosystems in the U.S. With support from the USDA-NIFA and through the collective efforts of many individuals representing Land Grant Universities, federal agencies, state departments of agriculture, and other stakeholders, the NPDN has grown into an internationally respected consortium of plant diagnostic laboratories. The specific purpose of the NPDN is to provide a cohesive, distributed system to quickly detect and identify pests and pathogens of concern. NPDN laboratories immediately report their findings to appropriate responders and decision makers. To accomplish this mission, the NPDN has invested in diagnostic laboratory infrastructure and training, developed an extensive network of first detectors through education and outreach, and enhanced communication among public agencies and stakeholders responsible for responding to and mitigating new outbreaks. We invite you to explore our website to learn more about the NPDN and our programs.
This webpage was created to inform the general public of the existence of the National Plant Diagnostic Network (NPDN) and to facilitate NPDN committee function, activities, and organization.
Information available to the general public resides on this home page. Additionally, each of the 5 regions has their own regional website that may contain regionally specific information. Regional websites can be accessed by selecting the regional acronym from the “NPDN Web Ring” box located on the left-hand side of this screen.
Questions about this program from the public should be directed to the following contacts:
1. Jeffrey Jones, Executive Director, NPDN, Director, SPDN, University of Florida
2. Kitty Cardwell, National Program Leader, National Institute of Food & Agriculture, USDA
3. Carrie Harmon, Secretary NPDN, University of Florida
