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.

United States Department of Agriculture.

At a ceremony today, USDA Under Secretary for Marketing and Regulatory Programs Greg Ibach declared the United States free of plum pox virus. Under Secretary Ibach signed a proclamation marking this historic announcement. "Today, our 20-year fight against plum pox disease is officially over,” Under Secretary Ibach said. “Working with our partners, we’ve eliminated this disease and protected the United States’ $6.3 billion stone fruit industry." Plum pox is a serious disease impacting stone fruit such as plums, almonds, and peaches. No other countries where plum pox disease is known to occur have successfully eradicated the disease. The disease was first detected in Pennsylvania in 1999.
