The Animal & Plant Disease and Pest Surveillance & Detection Network, was established by the Secretary of Agriculture to the Cooperative State Research, Education, and Extension Service (CSREES) to develop a network linking plant and animal disease diagnostic facilities across the country. The National Plant Diagnostic Network (NPDN) will focus on the plant disease and pest aspect of the program. The network is a collection of Land Grant University plant disease and pest diagnostic facilities from across the United States.
