The National Plant Disease Recovery System (NPDRS) is called for in Homeland Security Presidential Directive Number 9 (HSPD-9) which was issued in February of 2004. The purpose of the NPDRS is to ensure 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 in the U.S.
These recovery plans are a cooperative effort of university, industry, and government scientists. The plans outline what the scientists know about the disease, indicate the current preparedness, suggest the best IPM approach, and recommend priority research and education needs.

Citrus black spot was first discovered in Australia and was introduced to the U.S. in 2010. The means of introduction was possibly through the importation of unregulated and/or non-commercial infected fruit. Citrus black spot is a fungal disease of citrus that decreases yields by causing external blemished and premature fruit drop.
