Emerald Ash Borer (EAB) has been identified in Adams and Adair Counties.

According to the Iowa Department of Natural Resources’ website, trees that are attacked by the Emerald Ash Borer can die within two years.  Iowa State University Extension suggestions preventative treatment of ash trees within a 15 mile radius of a known EAB infestation.  Spring is the time to treat for EAB.  Please call for a FREE ESTIMATE before it’s too late!

Treatment…YES! It’s possible to save your Ash trees

With loads of information and opinions out there about the Emerald Ash Borer, it is important to focus on the facts.  Prevention and treatment IS possible.  The story of the Emerald Ash Borer is not one of complete doom and gloom.  In fact, independent university studies¹ have shown TREE-äge from Arborjet to be the most effective treatment of Emerald Ash Borer.  If treatment is the right plan for you, we offer two different treatment options: Trunk Injection and Soil Drench.

 Option #1:  Trunk Injection

 

Trunk injection application with TREE-äge® (emamectin benzoate) insecticide RECOMMENDED

Affordable, Effective, Proven:  TREE-äge® provides 2 year control.

Sealed in the tree: A precise dose is applied inside each tree, eliminating the need for chemical applications to the soil or foliage.  Safe and more environmentally friendly.

Consistent Results:  Controlled volume applications assures consistent results.  Only product on the market to achieve 2-year control of EAB.

Industry proven:  TREE-äge® is used by the USDA Forest Service and city forester in Chicago, Milwaukee, and many other municipalities.

Option #2:  Soil Drench

 

Soil drench application with Merit (imidacloprid) insecticide

Economical:  More affordable than trunk injection on small trees.

Consistent Results:  Effective on small trees (trunk diameter less than 6″).  Large trees can see inconsistent results.

Annual treatment is required.

Treatment cost varies with the size and number of trees and is based on the diameter at breast height (DBH). The following tables are a guideline for approximate cost, please call or email for an exact quote.

Trunk injection:
6” – 14” $7 – $11/inch
15” – 26” $7 – $12/inch
27” – up $8 – $12/inch
Soil drench:
3” — 6” $5 – $12/inch
7” – 12” $4 – $7/inch
Note:  Treat trees as a preventative measure before an infestation sets in for better results and healthier trees.  There is a significant delay from the time damage is done to the vascular tissue and symptoms are visible in the canopy.

Did you know?

Try using the National Tree Benefit Calculator to determine the yearly benefits provided by your ash tree.

Example:  A mature 17″ ash tree returns $173 per year in property value, energy savings, and air quality, while a newly planted 2″ tree of an alternate variety only returns a mere $10 per year.

It can cost $750 – $1,200 to remove a mature ash tree and replant it with an alternate variety.

When to treat?

Spring

Best time to treat for EAB.  Uptake of pesticide is fastest as trees are actively transpiring after a full canopy is developed.  Spring treatment will prevent adult EAB beetles from feeding and laying eggs in and on your trees.

Summer

After the beetle eggs have hatched, summer treatments will kill the larvae feeding under the bark.  Treatments are limited to days with mild to moderate temperatures, and trees may require watering the day before treatment.

Fall

EAB larvae are actively feeding on the tree’s vital vascular tissue.  Damage done in the fall will not be noticeable until the next spring when the canopy begins to leaf out.  Treatments are possible up until the time when trees begin to go dormant for the winter.

About Emerald Ash Borer

Emerald Ash Borer is considered to be one of the MOST DESTRUCTIVE tree pests ever seen in North America.  EAB is an invasive pest introduced from Asia that attacks ash trees (Fraxinus spp.).  The wood-boring beetle was found in parts of the Eastern U.S. and Canada in 2002 and continued to spread to neighboring areas.

EAB overwinter in Iowa as a larvae just under the bark.  In late spring, they pupate and emerge as an adult beetle through a D-shaped hole in the bark about 1/8” in diameter.  The adult is a small, metallic green beetle that feeds on the trees’s canopy leaves before reproducing and laying eggs in the cracks of the bark.  The eggs hatch into larvae which burrow through the bark into the tree where they continue to feed in a serpentine pattern until fall.

Iowa State University Extension entomologists recommend having your ash trees checked or treated if you are located within 15 miles of Creston or another EAB infestation to prevent this destructive pest.  We have identified EAB infested trees in multiple areas of Creston.  We can assist you with treatment for any size tree.

 

ESB_Treatment

A bulletin from North Central Integrated Pest Management (IPM) Center offers these key points about EAB:

1. If EAB has not been detected within 15 miles, your trees are at low risk.

2. Trees that are already infested and showing signs of canopy decline when treatments are initiated may continue to decline in the first year after treatment, and then begin to show improvement in the second year due to time lag associated with vascular healing. Trees exhibiting more than 50% canopy decline are unlikely to recover even if treated.

3. Tree-age is the  only product tested to date that controls EAB for more than one year with a single application. It also provided a higher level of control than other products.

4. Effectiveness of insecticides has been less consistent on larger trees.

5. If using Merit, we recommend that trees larger than 15-inch diameter be treated using the highest labeled rate and best results will be obtained with two applications per year.  Merit insecticides for homeowners can be applied only once per year.

6.  Homeowners wishing to protect trees larger than 15-inch diameter should consider having their trees professionally treated.
