(Columbia) The South Carolina Forestry Commission and the USDA Forest Service have confirmed that a devastating disease of redbay and other plants has been identified in a Socastee neighborhood.
According to a press release, Laurel Wilt was found was found in an area north of Socastee and is the furthest north in South Carolina that the disease has been found.
Before this discovery, Laurel Wilt had been found only in Beaufort, Jasper, Hampton, Allendale, Bamberg, Barnwell, Orangeburg, Colleton, Dorchester, Charleston, and Berkeley counties.
This disease is on the move. It has identified in 25 Georgia counties and 21 Florida counties.
What is Laurel Wilt?
The disease is introduced into the tree by the non-native Redbay Ambrosia beetle (Xyleborus glabratus). The female beetle bores through the bark of the tree carrying the fungus on her mouthparts. Once the beetle is inside the tree, she makes tunnels where she will lay eggs. The fungal spores grow in these tunnels, blocking the movement of water from the tree roots and causing the tree to wilt and eventually die from lack of water. This fungus is extremely fast acting and trees typically will die within a month after being infected.
How do I know if I have it on my property?
Laurie Reid, a forest health specialist with the South Carolina Forestry Commission, says symptoms of a Laurel Wilt disease include drooping reddish or purplish foliage. Evidence of ambrosia beetle attack may be found in the main stem; often strings of chewed wood, called toothpicks can be seen sticking out of the entry holes. Removal of tree bark reveals black streaking in the outer wood.
If I have Laurel Wilt on my property, what should I do?
This exotic pest can spread to new areas through the movement of infested wood, such as firewood or dead wood being transported for disposal. Homeowners with dead redbay trees encouraged to keep cut trees on their property. Proper disposal of redbay includes leaving wood on site, cutting or chipping wood on site, or burning wood on site in compliance with local ordinances. Remember that by law you must notify the South Carolina Forestry Commission before conducting any outdoor debris burn. Each county has a toll-free notification number. They are listed at http://www.trees.sc.gov/fyard.htm.
Dead trees should not be transported off site to a landfill or off site to be used as firewood.
