Emerald Ash Borer (EAB) detected in four more counties
This invasive insect that kills ash trees, has been detected in Fulton, Hancock, Lake, and Marshall counties.
State entomologist Phil Marshall has recommended that movement of regulated ash material and hardwood firewood within these counties be limited to reduce further spread of the insect.
These counties will be part of a new quarantine approach in which the northern half of Indiana, bordered on the southern edge by Benton, Tippecanoe, Boone, Hendricks, Marion, Hancock, Madison, Delaware, and Randolph counties, will be considered "generally infested." Movement of regulated ash items within the generally infested area is no longer restricted. To move regulated materials outside of this generally infested area, a compliance agreement must be obtained from the Indiana DNR.

For more information on EAB, or to report an infestation, visit www.eabindiana.info or call Indiana DNR's toll-free hotline at 1-866-NO EXOTIC (663-9684).

Thousand Canker disease affecting black walnut trees
The Indiana Department of Natural Resources, Division of Entomology & Plant Pathology, is activating Indiana's Emergency Rule for Thousand Canker Disease (TCD) of Black Walnut, effective August 30, 2010. This fungal disease is spread by a small twig beetle, eventually leading to the death of infected trees. TCD disease, endemic in the Western US, was recently identified in Tennessee.
For more information view the US Forest Service Pest Alert, Indiana Emergency Rule and Indiana Walnut Council. Things we can do to help prevent this disease: check your black walnut trees for signs of this disease; report any dead or declining walnut trees to 1-1-866-NO-EXOTIC; don't move firewood of any kind as it spreads insects and diseases; and don't move walnut material from a known infested area.
