Description

In Pennsylvania, peach, plum, nectarine, and apricot stone fruit and native and ornamental Prunus are susceptible to PPV, Strain D. Pennsylvania was declared free of the virus in October 2009 after three years of negative testing. Formal orchard surveys for the virus are no longer occurring, though standard testing of nursery material continues. Additional orchard monitoring may be proposed in future years, as part of ongoing early detection strategies for pests of concern. Lifting of the quarantine in Pennsylvania opened many acres for replanting Prunus. However, growers need to remain vigilant for any early indications the virus has returned. New plantings offer the opportunity for a "fresh start" and growers must plan carefully to get the most from their investment.

This video was produced by Penn State Extension in 2000 and recounts the partnership that developed between Penn State, USDA, the Pennsylvania Department of Agriculture and other scientists from around the world to battle the emergence of Plum Pox in Pennsylvania.
