It is commonly known that the Emerald Ash Borer will kill Ash trees in Cincinnati.  But what is not known is there are treatments that can save those trees!

Example of Mariemont: the city was given bad advice and used a formulation that was not professional strength.  They cut down the trees without fighting for them.  A second opinion and the right treatment might have saved those trees.

Blaming nature is no substitute for due diligence.

Where Today’s EAB Mindset Comes From

The mindset in Cincinnati, with respect to the Emerald Ash Borer, stems from influential people that preached the message “your ash trees are doomed.”

On October 29, 2006 the Cincinnati Enquirer published an article “Trees Losing the Fight Against Ash Borers”. Recent, rapid advances in treatment technology have proven these perceptions to be inaccurate today.

Here are the four main points from that article…

1.  “Ash trees… doomed to death from attacks by the emerald ash borer. Some say it will be within the next year; others predict the destruction over the next five to 10 years.”

2.  “…we have little data to suggest that continual, annual applications will keep borers out of any specific ash tree.”

3.  “The best treatments are not 100 percent effective and, eventually, the insects will infest a treated tree and kill it.”

4.  “seek a written guarantee… there are no guarantees.”

None of these are true today, yet but many people still choose to believe them.

In the white paper “Insecticide Options for Protecting Ash Trees from Emerald Ash Borer,” scientists from five universities identify provide ample data that treatments based on Emmectin Benzoate, such as TREE-äge, have proven 100% effective for a period of at least two years.

And the fourth point is also not true today.  Back Tree Service is one local tree care company that has a 100% guarantee if their proven system of holistic care and treatment is used.

There are two basic steps to Back Tree Service’s holistic treatment system.  The first is injection of the TREE-age formulation into the trunk of the ash tree using the ArborJet system.  The second step is fertilizing and soil remediation.

Soil remediation is done by using a special Pneumatic Vertical Mulching tool that breaks up and aerates Ohio’s heavy clay soil.  A time released fertilizer is then added to the root system.  This combination increases tree health, a critical step in protecting trees against infestations such as the Emerald Ash Borer.

The result of these two steps is a healthy tree inoculated against Emerald Ash Borer, and other insects as well, including the next insect to hit the tri-state.

Another major misconception is that treating ash trees costs too much compared to removal and replacement.

How can a two inch diameter tree be considered a replacement for a heritage tree that may have been growing for over 100 years?  There is no replacement for heritage trees.

The State of Ohio conducted a study in 2006, The Potential Economic Impacts of Emerald Ash Borer. They found that the average ash tree was 12.4” in diameter.  Including landscape value, removal and replacement, their findings indicate that the total average cost would be $1,772 to the home owner per average tree.

But with today’s proven TREE-äge formulation, that 12.4” diameter tree could be treated for only $149.

Those who want to rip-and-replace justify their actions by saying that the treatment needs to be repeated every two years.  Do the math.  Treatment is way better on cash flow than replacement.

And what about when the next infestation comes, will they rip-and-replace the replacement tree as well?

In the 1950’s and 60’s Dutch elm disease, a disease carried by insects, caused thousands of elm trees to be destroyed.  And today the Emerald Ash Borer is the next cycle of attack on trees.  If we destroy and replace trees, every time there’s a threat, and choose not to treat them, then what is the true cost over time?  What are we leaving for our grandchildren?

It’s time to protect our trees and stop this cycle of destruction!
