What is the Emerald
Ash Borer?
The Emerald Ash Borer (EAB) is a beetle from
Asia that preys on Ash Trees and was first
discovered in Ohio in 2003. The EAB lives a
majority of its life under the bark where its larvae
develop into white worms and finally into dark
metallic green insects about an inch and a half
long. The larvae feed off of the tissue of the tree
directly under the bark; therefore, killing the tree
by stopping the transportation of water and
nutrients. When the warm weather arrives, the
larvae mature and take to the air leaving
D-shaped holes in the bark. The EAB mates at this
time and the cycle starts over by this time
traveling to new ash trees.

What is the impact of
the Emerald Ash Borer?
Ash trees are common in
our City and region. All trees contribute to the
beauty and environmental stability of the City.
Trees help with energy costs by helping to cool
surface temperatures and aid in stormwater issues by
soaking up many of gallons of water that the rest of
the soil is not able to absorb. Dead trees are
a danger to those on the ground if a strong wind or
heavy rain uplifts their roots. Therefore, the EAB has an aesthetic, economic and safety impact on
daily life.
The
Ohio Department of Agriculture (ODA) has placed a
majority of
counties under quarantine, including Greene County.
The quarantine makes it illegal to transport ash
trees, parts of ash trees, and all hardwood firewood
from any quarantined county into a non-quarantined
county without a compliance agreement from the ODA.
Firewood dealers, businesses, or woodlot owners
interested in marketing and transporting ash trees
or firewood from quarantined areas can do so only
with a department-approved compliance agreement.
These agreements stipulate handling practices that
mitigate the artificial spread of the EAB.

to view Ohio’s EAB quarantine map on the ODA web
site. Violators of this quarantine may face fines up
to $4,000. Due to a federal quarantine, it is also
illegal to take these items from the state of Ohio.

What is the City of
Bellbrook doing?
Currently, the City has
completed the counting of street trees and trees on
city property with the
help of local volunteers, Greene Co Master Gardeners
and the OSU Extension Office to help measure the impact
of the EAB. This counting helps the City
analyze the costs and what should be done to
minimize the above impacts.

Steady Invasion of the Emerald Ash Borer (8/2010)
The infestation of the Emerald Ash Borer (EAB) in Ohio
continues at a steady rate. A recent update from
the Ohio Department of Natural Resources (ODNR) and
the Greene County OSU Extension Office showed that
the Borer has been found in ash trees as close as
Beavercreek and Fairborn in Greene County and in ash
trees in Franklin and Springboro in Warren County.
New communities within already quarantined counties
are added on a monthly basis.
Southwest Ohio has an abundance of all varieties of
ash trees and a watchful eye is important to
recognize the signs of a possible EAB infestation.
Specimens of a suspected Emerald Ash Borer are now
able to be submitted for identification from
quarantined counties, such as Greene County, to the
Ohio Department of Agriculture (ODA). These
specimens are processed for identification, and if
identified as EAB, the Greene County map will be
updated with a red dot on the location
where the sample was collected. Maps for infested
counties are linked from the ODA website and are
available at
http://www.agri.ohio.gov/divs/plant/eab/eab-index.aspx
.
If
you have noticed a possible infestation of the EAB
in your yard and are interested in submitting a
specimen for confirmation, samples can be sent
directly to ODA, or taken to the Greene County Ohio State University Extension office at 100 Fairground Road
in Xenia. The specimen form below must accompany
the EAB specimen. Please follow the collection
instructions closely so that specimens are able to
be easily identified.
The Ohio Department of Agriculture appreciates the samples
that are submitted in order to continue to monitor
the spread of the Emerald Ash Borer in quarantined
counties in Ohio.

Ohio Department of Agriculture
Expands Emerald Ash Borer Quarantine (1/2010)
Department adds 14
counties to existing quarantine
REYNOLDSBURG, Ohio (Jan.
14, 2010) – Ohio’s Emerald Ash Borer quarantine was
expanded today by the Ohio Department of Agriculture
to include 14 additional counties. The quarantine
helps slow the spread of the ash tree-killing insect
to uninfested parts of the state by prohibiting the
movement of all hardwood firewood and ash tree
materials.
While the invasive pest
has not been detected in the following 14 counties,
the department issues this quarantine to make the
movement of ash trees, parts of ash trees and all
hardwood firewood more practical among counties that
are adjacent to previously quarantined areas. The
following counties are now on the quarantine list:
Adams, Ashtabula, Brown, Clinton, Coshocton,
Fayette, Geauga, Highland, Holmes, Knox, Lake,
Madison, Ross and Trumbull.
Since Emerald Ash Borer
was first discovered in Ohio in 2003, the department
has placed 67 counties under quarantine. The
quarantine makes it illegal to transport ash trees,
parts of ash trees and all hardwood firewood from
any quarantined county into or through a
non-quarantined county without a compliance
agreement from the Ohio Department of Agriculture.
Violation of this quarantine could result in fines
up to $4,000. A federal quarantine makes it illegal
to take these items out of the state of Ohio.
Firewood dealers,
businesses or woodlot owners interested in marketing
and transporting ash trees or firewood from
quarantined areas can do so only with a
department-approved compliance agreement. These
agreements define handling practices that reduce the
artificial spread of Emerald Ash Borer.
Ash trees infested with
Emerald Ash Borer typically die within five years.
The pest belongs to a group of metallic wood-boring
beetles. Adults are dark green, one-half inch in
length, one-eighth inch wide, and fly from early May
until September. Larvae spend the rest of the year
beneath the bark of ash trees and leave D-shaped
holes in the bark about one-eighth inch wide when
they emerge as adults.
Suspected Emerald
Ash Borer adults and larva can be confirmed by
sending the suspected specimen(s) to the Ohio
Department of Agriculture for identification using
the form located on the department’s Web site. Visit
www.agri.ohio.gov and click on “Emerald Ash
Borer Program” located under the “Regulatory
Programs” tab. The form is available by clicking
“Submit a Sample” on the left-hand side.

Emerald Ash Borer, maps, compliance agreements,

Update from the Greene County
OSU Extension Office Concerning the EAB... (9/2009)
On
July 28, 2009 the Ohio Department of Agriculture
(ODA) added Greene County to the list of counties
where EAB has been found. The infested trees and
insects were found in western Greene County. With
this announcement Greene County joins surrounding
counties of Montgomery, Miami, Clark and Warren
where the insect has been as well. The ODA is still
asking anyone in Greene County who thinks they have
the EAB to notify them as they want to track
movement of the insect.
As a
homeowner you may be wondering what one can do to
protect your ash trees or deal with the potential
loss of one of our most common trees in Ohio. If
planting trees on your property, consider utilizing
other species of trees than Ash. If you are unsure
whether you have Ash trees, get someone to ID the
trees for you. You can bring leaf samples into the
Greene County Extension Office. Control measures are
numerous and can be costly. One of the first things
homeowners and incorporated areas need to do soon is
to identify where the Ash trees are located on your
property and do they present a risk to people,
buildings, cars etc. Some of our communities, like
Xenia for example, has done such a tree inventory
with the help of the Greene County Master Gardeners
and other volunteers. Once the Ash trees are
located, you can decide which tree(s) pose a danger
and whether you want to remove them or will try to
save them through the use of insecticides. The Ash
tree becomes very brittle once it dies and therein
lies the danger if the tree poses a risk to
buildings, cars, etc. An Ash tree growing in a
wooded area may be left alone to break off and fall
if it poses no threat to other valuable trees.
There are several insecticides on the market and
some of the testing has shown promise in protecting
trees from the EAB. There are four types of
insecticide options: 1) systemic insecticides that
are applied as soil injections, 2) systemic
insecticides applied as trunk injections, 3)
systemic insecticides applied as lower trunk sprays,
and 4) protective cover sprays that are applied to
the trunk, main branches and possibly the foliage.
Before you embark on one of these options consider
the cost, effectiveness and ease of application.
These important points are covered in the Greene
County OSU Extension fact sheet titled: “Insecticide
Options for Protecting Ash Trees from Emerald Ash
Borer” at the Emerald Ash Borer Info link below or
you can also contact the Greene County OSU Extension
Office for a copy.
Some
general thoughts to keep in mind are: 1) if the Ash
tree is 15 inches or more in diameter research has
shown you may be ahead to have a professional treat
it; 2) Ash trees exhibiting a 50 % or more loss of
tree canopy probably are lost; 3) soil drenches are
effective if applied in the spring or fall when the
ground is not frozen or the soil is too wet; 4)
there is only one type of treatment which will give
more than one year of protection with a single
application and that is Emamectin benzoate. This a
tree injection product applied in the spring. The
common product available to homeowners is Bayer
Advanced Tree and Shrub Insect Control. It is a soil
drench material applied in mid-fall to late spring.
Always follow the label instructions on these
products.
