Today’s Topic: A dozen NC counties now quarantined because of emerald ash borer

by | Jul 28, 2015


Agriculture Commissioner Steve Troxler sits down each week with Southern Farm Network’s Rhonda Garrison to discuss “Today’s Topic.”

Twelve North Carolina counties are now under a quarantine aimed at preventing the spread of emerald ash borer.

Since June, seven counties have been added to the quarantine, which restricts the movement of hardwood firewood, ash nursery stock and other ash materials. The latest counties under quarantine are Durham, Franklin, Graham, Johnston, Orange, Wake and Wilson. The borer was detected in Granville, Person, Vance and Warren counties in 2013, and it was found in Wayne County earlier this year.

Emerald ash borer is a devastating pest to ash trees, eventually killing the trees where the insects are found. The department is continuing to monitor other counties for this highly destructive pest through trapping and visual assessment of trees. Department personnel will be pulling traps in early August, and Commissioner Troxler says it’s possible they will find sites in even more counties.

Under the state quarantine, all hardwood firewood and plants and plant parts of the ash tree cannot be moved outside the county. Only firewood that has been treated by an approved U.S. Department of Agriculture method, such as treatment in an approved kiln, can be moved outside the quarantine area.

Symptoms of emerald ash borer include a general decline in appearance. Clumps of shoots emerging from the trunk of the tree and increased woodpecker activity are other symptoms. The pest can affect any of the four types of ash trees grown in the state (green, pumpkin, white and Carolina).

Land owners are encouraged to report any symptoms in ash trees to the department’s Plant Industry Division at 1-800-206-9333.
