National Plant Disease Recovery System

The National Plant Disease Recovery System (NPDRS) is called for in Homeland Security Presidential Directive Number 9 (HSPD-9).  The purpose of the NPDRS is to insure that the tools, infrastructure, communication networks, and capacity required to mitigate the impact of high consequence plant disease outbreaks are such that a reasonable level of crop production is maintained.

Each disease-specific plan listed below is intended to provide a brief primer on the disease, assess the status of critical recovery components, and identify disease management research, extension, and education needs.  These documents are not intended to be stand-alone documents that address all of the many and varied aspects of plant disease outbreak and all of the decisions that must be made and actions taken to achieve effective response and recovery.  They are, however, documents that will help USDA and others guide further efforts directed toward plant disease recovery.  The plans are a cooperative effort of university, industry, and government scientists sponsored by The American Phytopathological Society and the United States Department of Agriculture.
