The National Plant Diagnostic Network and Agricultural Biosecurity in the U.S.

The National Plant Diagnostic Network (NPDN) was created to enhance the capabilities of existing diagnostic laboratories in the nation to detect and report introduced pathogens, pests and weeds of high consequence to plant agriculture and natural ecosystems.  An important goal of the network is to coordinate diagnostic and scientific expertise at land-grant universities, state departments of agriculture, agencies within the USDA (CSREES and APHIS), and other organizations involved in agricultural production and security.  The program, which is administered through the USDA, was established in 2002 through funding created by the Homeland Security Act in response to concerns that agricultural pests and pathogens could be used as agents of bio-terrorism.  Responsibilities of the NPDN include the compilation and establishment of diagnostic protocols for priority agents, the development of a web-based distributed plant pest diagnostic and reporting system for the nation, the provision of up-to-date information on plant pests for the nation, the development of analytical tools to exploit these data, and the recruitment and training of first detectors.  The national network is organized into 5 regions, with regional centers located at the University of California, Davis (Western Region), Kansas State University (Great Plains Region), Michigan State University (North Central Region), the University of Florida (Southern Region), and Cornell University (Northeastern Region).  A parallel network for veterinary medicine, the National Animal Health Laboratory Network, also has been established with regional centers located at the same institutions as the NPDN regional centers.  The mission and design of the NPDN, its programs, and progress towards meeting network objectives, will be presented and discussed.

Richard Bostock is a professor and former chair (1999-2005) of the Department of Plant Pathology at the University of California, Davis.  In 2002, he was appointed as the founding Director of the Western Region of the National Plant Diagnostic Network (NPDN).  The NPDN is a distributed system comprised of public institutions for the purpose of quickly detecting and identifying high consequence pests and pathogens.  The network links plant health professionals, researchers and diagnostic labs throughout the region, providing a way for them to share information about occurrences of plant diseases and pests that could have an impact on the region's most economically important crops.   This information also is reported to first responders and decision makers. Funding for the network is provided through the United States Department of Agriculture. Dr. Bostock received his Ph.D. in Plant Pathology at the University of Kentucky in 1981, and was appointed to the faculty at UC Davis that year.  His research and teaching interests are the biochemistry and molecular biology of plant-microbe interactions and general plant pathology.  He teaches several courses in the department and in the Science and Society program on various aspects of plant pathology, plant-microbe interactions, and issues related to food production.
