Chance to learn more about emerald ash borer

Emerald ash borer is a small, metallic-
green bullet-shaped beetle.
The past week I've been speaking to PMPs at CEU conferences about the emerald ash borer.  Many folks have asked why they've never heard about this pest. I guess that's because it's a relative newcomer to the state and its impact is just beginning to be felt.

If you are one of the many in our industry who has heard little or nothing about this insect, let me enlighten you. The emerald ash borer, Agrilus planipennis (EAB), is a wood boring beetle that attacks trees in the genus Fraxinus, which we know as ash. Since it was first discovered in SE Michigan in 2002 it has spread with alarming speed throughout the midwest.  In 2017 the first beetle was found in east Texas.

The EAB is probably the most devastating forest pest since chestnut blight.  In areas where it has been in place for 10+ years it has virtually wiped out every ash tree. Some fear that certain ash species may be on the edge of extinction thanks to the borer. We have every reason to think the same thing will happen in Texas.

Ash is not as common in Texas compared to Michigan and other parts of the Midwest; but it is an important tree, especially in areas along streams and river bottoms. And it's a very important tree if you have one in your backyard.

Not every one of you provide lawn or tree care services, but if you do you should keep your eye on this beetle.  Even if you don't "do trees" you can still provide a service to your customer by alerting them to the risk of this beetle if they have ash trees on their property.

Emamectin benzoate is an effective
treatment applied by certified applicators.
Currently, EAB has been found in Marion, Cass, and Harrison counties in far east Texas.  Most recently a well-established infestation of the borers has been found in west Tarrant county, just a few miles to the northwest of Fort Worth. Anyone who cares for an ash tree who lives within 15 miles of a known infestation should consider their trees at risk (this includes most homes in Fort Worth), and should consider having it treated.

A handful of insecticides can provide protection of an ash tree at reasonable cost. If you are interested in being on the leading edge of how to treat ash trees for EAB in Texas, there are three workshops coming up, sponsored by the Rainbow Treecare company (Rainbow makes one of the leading insecticides for EAB management). Two of the workshops focus on community EAB management strategies, and one will provide a general introduction to EAB. 

These workshops are webinars.  If you've never attended a webinar, it's a pretty cool, and easy, way to learn. You sit at home or in your office, link up to a website, and watch and listen. You will also have the chance to submit questions and interact with the speakers.  To read about the webinars and register, go to https://register.gotowebinar.com/register/2236702821873051149

Other places to learn more about EAB include:

  • The USDA Emerald Ash Borer website is a great source of authoritative information about EAB.   
  • The EAB Information Network is a multinational effort to assemble information about the borer including blogs and general information. 
  • EAB University is part of the EAB Information Network and has recorded webinar sessions on a wide variety of topics from top researchers and arborists in the country. All classes are free.
  • Emerald ash borer found in Tarrant County. Citybugs blog. Story of EAB discovery near Fort Worth.

I hope to write more about this beetle in the future. In the meantime, get out your tree books and read up on ash. Once you learn to distinguish ash you will be able to tell whether a customer's tree is at risk.

Webinar on Emerald Ash Borer

Trunk injections made by professionals are
one of the most effective tactics for
protection of urban trees. Learn more about
EAB management options at Wednesday's
free seminar.
For anyone interested in learning the latest information about the exotic pest, emerald ash borer, there is a training opportunity later this week that might be just the ticket.  Dr. Dan Herms, professor and chair of the entomology department at Ohio State University, has been involved in EAB research nearly since its arrival.  He will be offering a one hour webinar this Wednesday at noon.

Dr. Herms will be talking about the implications of EAB for both natural and urban areas of the Southeast, the next major region this insect is expected to invade.  The EAB is now known to be within 40 miles of Texas, and may already be here.  Every ash tree in eastern Texas is at risk, and arborists, especially, will benefit from advanced training on this insect.

Here's the official announcement:
The emerald ash borer (Agrilus planipennis Fairmaire) is now found in 25 U.S. states and Canada in North America, and is rapidly expanding its range across the eastern United States. It has the ability to kill all species of ash trees (Fraxinus spp). 
Being prepared for EAB is important if this pest is to be contained. This webinar will review EAB identification, biology, ecology and management strategies, with particular emphasis on the southeastern U.S. EAB is now considered the most devastating wood pest in North America. 
Dr. Herms has been involved in EAB research and outreach since its discovery in Ohio in 2003, and is also a collaborator with other entomologists researching the pest. No pre-registration is necessary for this webinar. Click here for information on how to join the webinar on April 20, 12:00 CDT. 
Tree care companies, Extension specialists, Master Gardeners, urban foresters, Natural Resources Conservation Service specialists, tree boards, tree nurseries, municipal managers, nature conservancies, and anyone concerned about the future of this important tree species will find this a very useful and enlightening presentation.
