In wake of the events of September 11, 2001, as well as subsequent federal legislation known as the Agbioterrorism Act of 2002, efforts have been undertaken to network the nation’s land grant plant disease and insect diagnostic facilities under a model that would mimic the network that is currently available for detection and tracking of human diseases coordinated by the Center for Disease Control (CDC). The goals of the new National Plant Diagnostic Network (NPDN) are to link and foster communication between diagnostic clinics, and enhance their ability to quickly detect and respond to new and emerging agriculture plant pathogens that might be accidentally or intentionally introduced in the United States.
