Today, I attended the monthly brown bag at the Milwaukee County Extension offices.
The topic was Emerald Ash Borer (Agrilus planipennis).
The presenters were Robert Tomesh and Phil Pellitteri.
They offered a summary of the problem and some possible remedies in terms of insecticidal treatments.
The outlook remains bleak, similar to the Dutch Elm Disease and Chestnut Blight disasters.
They recommended three websites to keep up with developments:

http://www.emeraldashborer.wi.gov/
http://www.emeraldashborer.info/
What is most frustrating to me is that we did not learn our lessons from the previous episodes. Too many communities that were particularly hard hit by the Dutch Elm Disease replaced elms with only ash trees rather than a diversity of trees.
How many times are we going to repeat this mistake?
