More on Emerald Ash Borer
There are also a couple of new publications available online that I wanted to share. The first is a new edition (June 2014, second edition) of Insecticide Options for Protecting Ash Trees from Emerald Ash Borer. It was put together by the Northeast IPM Center. Another entitled Frequently asked Questions Regarding Potential Side Effects of Systemic Insecticides Used to Control Emerald Ash Borer is a fact sheet that was put out by Minnesota, Michigan, and Ohio Extension Services. It may help address concerns about treating trees.

DCNR preserving seeds of ash and other tree species that are facing threats
Inside the envelopes that are delivered to the Penn Nursery every fall is a future forest. The envelopes contain the seeds of ash trees, which are collected by staff from the state Department of Conservation and Natural Resources and sent to the agency’s Penn Nursery during a brief two-week period each fall. The effort may be the last chance for ash trees in the state, which are being infested with the emerald ash borer.
Once the insect burrows into a tree and lays its eggs, death is imminent. But at Penn Nursery in Centre County, there is hope. That’s where the seeds are processed and eventually shipped to a U.S. Forest Service lab in Colorado, where they are placed in cryogenic storage. “A lot of the seed can be stored for 100 years,” said Tina Alban, forest nursery operations manager for DCNR’s Bureau of Forestry. “Someday, we’ll pull it back out and use it to re-establish the ash tree in Pennsylvania’s forest.”
The emerald ash borer, which is actually a beetle, has killed tens of million of ash trees since it was first identified in Michigan in 2002. It surfaced in Pennsylvania in 2007 and has been found throughout the state. Click here to read the rest of the story.
