Meet the Honeysweet Plum: A virus-resistant plum that ARS hopes to bring to market soon. They are large and oblong with a very sweet, flavorful taste. ARS created the Honeysweet variety using RNAi, a biotechnology method that makes them immune to the plum pox virus. Plum pox infects stone fruit trees: plums, peaches, apricots and cherries. Once infected, the fruit discolors and falls from the tree prior to maturation. There is no natural, genetic resistance to the virus.

The 20-year fight against plum pox – a serious agricultural disease capable of devastating stone fruits like peaches, apricots, cherries, and almonds – is finally over, thanks to a cooperative effort by the Agricultural Research Service and their partners.

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.
