Emerald Ash Borer

Emerald ash borer has been found recently near Dunlap and in Peoria in Peoria County. It has also been found recently in Minier in Tazewell County. Peoria and Tazewell counties are just outside of the present quarantine boundary, so it will be expanded to include those counties.

New county infestations earlier this year within the existing quarantine boundary include Savanna in Carroll County, Freeport in Stephenson County, and Danville in Vermilion County. It is now found in 36 Illinois counties. We reported it being found in St. Charles, Missouri earlier this summer. St. Charles is just northwest of St. Louis, causing concern for areas in Illinois east of the St. Louis area.

The second edition of "Insecticide Options for Protecting Ash Trees from Emerald Ash Borer" has been published this year and is available at It provides an update of brand names of labeled insecticides to control emerald ash borer and additional information on the effectiveness of insecticides.

The national 2014 Emerald Ash Borer Research and Technology Development Meeting will be held on October 15-16, 2014 at the Ohio Agricultural Research and Development Center (OARDC) in Wooster, Ohio. This is an excellent opportunity to get the latest information on Emerald Ash Borer through oral and poster presentations.

Attendance is limited to the first 225 people that register. The deadline to submit paper and poster titles is September 26, 2014. The registration fee is $50. Additional information including registration and lodging information is at (Phil Nixon)
