Agriculture Department Announces Detection of Thousand Cankers Disease in Pennsylvania Trees, Enacts Quarantine to Prevent Spread
Thousand Cankers Disease has been detected for the first time in Pennsylvania, and a quarantine restricting the movement of wood from Bucks County and other states known to have the disease is effective immediately.
The disease was found on a black walnut tree in Plumstead Township, Bucks County, and reported by the property owner to Penn State Cooperative Extension. The sample was verified by the state and federal Departments of Agriculture.
"Thousand Cankers Disease poses a significant threat to Pennsylvania's $25 billion hardwoods industry," said Agriculture Secretary George Greig. "To help ensure this disease does not spread to other regions throughout the state, I urge Pennsylvanians to comply with the quarantine restricting the movement of wood from Bucks County."
The quarantine restricts the movement of all walnut material including nursery stock, budwood, scionwood, green lumber and firewood. It also covers other walnut material -- living, dead, cut or fallen -- including stumps, roots, branches, mulch and composted and uncomposted chips. Due to the difficulty in distinguishing between species of hardwood firewood, all hardwood firewood is considered quarantined.Read this article in its entirety
