Ash Trees Are Dying in Philadelphia as Emerald Ash Borers Kill Trees that Have Not Been Protected with Treatment

Share Article

Emerald Ash Borers are destroying Ash Trees in the Philadelphia area yet many can still be saved. A video by Giroud Tree and Lawn shows the destruction on a street lined with Ash trees in Northeast Philadelphia; several are dead or dying but two that were protected with treatment are alive and healthy.

Giroud Tree and Lawn shows the dead Ash tree on the right was killed by Emerald Ash Borers.  The healthy tree on the left was protected against attack by TreeAge Trunk Injection.

The Ash trees treated with TreeAge trunk injections show no signs of Emerald Ash Borer activity.

Emerald Ash Borers kill Ash trees in as little as 1-3 years. The signs of this fatal pest's destruction can be seen throughout the Philadelphia region. A video by Rob Nagy, ISA Certified Arborist at Giroud Tree and Lawn, shows a street in Northeast Philadelphia that is lined with Ash trees. While several are dead or showing signs of decline from Emerald Ash Borers, two Ash trees continue to thrive.

"The contrast is startling," says Rob Nagy. "These Ash trees are growing side by side and Emerald Ash Borers are killing them all except for the two that have been protected with TreeAge trunk injection treatments."

In a quest to find the best treatment options, researchers have exhaustively studied EAB. “Insecticide Options for Protecting Ash Trees from Emerald Ash,” presents conclusions from over a decade of research by four universities. This research confirms that: “Emamectin benzoate consistently provides at least two years of EAB control with a single application, even in large and very large trees under intense pest pressure. It also provided a higher level of control than other products in side-by-side studies.

“In good conscience, a company should not take money from homeowners for treatments that do not fully protect a tree from Emerald Ash Borer, says Lou Giroud, ISA Certified Arborist and President of Giroud Tree and Lawn. “While other treatments may reduce EAB populations, the deadly pest can still be in the tree and continue to destroy it over time. Tree-age trunk injection is the only treatment that Giroud recommends to its customers.”

Here are the questions a homeowner needs to ask before buying Emerald Ash Borer control treatment and the answers that the professional should provide:
1.    Have Emerald Ash Borer been found near the property? Treatment should be done once EAB has been confirmed within 15 miles of the property.
2.    Does the tree already have signs of EAB? Look for D shaped exit wounds and crown die back.
3.    Is the tree still healthy enough to absorb and transmit the treatment through the tree? More than half the tree’s crown must still be alive and in full leaf.
4.    Which treatment option does the professional recommend and why? As noted above and in a video by Arborjet, the manufacturer, Tree-age trunk injections provide the best control against Emerald Ash Borer and last for two years.
5.    Is the technician licensed by the state to perform the treatment? Licensed professionals know how to calculate the right dosage for the size of the tree and the proper set-up for the application.

Bottom line, upfront research and asking the right questions can help homeowners make a good decision about whether or not to protect Ash trees from Emerald Ash Borer.
