EAB Insecticides: Label Guidance for Use Limits
February 2012 - From the Minnesota Department of Agriculture - Some insecticides used to control emerald ash borer (EAB) have annual per acre use limits. The Minnesota Department of Agriculture (MDA) offers this label guidance to help applicators and others comply with label directions, meet tree treatment objectives, and minimize environmental impacts. The MDA completed a special registration review of EAB insecticides in 2011. The review concluded that insecticides commonly used to control EAB are not likely to harm human health or the environment when used according to label directions.
Frequently Asked Questions Regarding Potential Side Effects of EAB Insecticides
February 2011 - Research and Extension Specialists from Michigan State University, the Ohio State University OARDC and Extension, and University of Minnesota Extension have put together a comprehensive publication that addresses questions and concerns regarding insecticide use to control emerald ash borer.

Ash canopy thinning and dieback photo illustration
September 2007 - Effectively treating EAB-infested ash trees can be tricky. Many people are unaware of the degree of infestation their ash tree(s) may have, so Dave Smitley, Michigan State University entomologist, has created this guide that explains the stages of ash canopy thinning and dieback. These stages may help the homeowner determine if it is worth the effort to try to save the tree, or if it may be best to take it down.
"Slow Ash Mortality" - SLAM Pilot Project
The SLAM project is a collaborative effort involving Michigan State University, the USDA Forest Service, USDA Animal and Plant Health Inspection Service (APHIS), Michigan Technological University (MTU), the Michigan Dept. of Agriculture and Rural Development (MDARD), the Michigan Dept. of Natural Resources (MDNR), and Michigan Conservation Districts in Michigan\'s Upper Peninsula. The goal of the SL.A.M. pilot project in Michigan's Upper Peninsula is to delay and slow the expansion of ash mortality by reducing populations of the beetle in newly-infested sites, outside of known EAB infestations.
IMPORTANT NOTE: Since the emerald ash borer's discovery in 2002, research has been ongoing to develop tools to control and eliminate this pest. Currently, there are a number of treatments available for use by homeowners or tree care professionals that can provide a varying degree of beetle control. A review of all options is recommended. As more methods are developed, more information will be available.

Minnesota GreenStep Cities -- Urban Forests and Soils
Minnesota GreenStep Cities is a voluntary challenge, assistance and recognition program to help cities achieve their sustainability and quality-of-life goals. This free continuous improvement program, managed by a public-private partnership, is based upon 29 best practices. Each best practice can be implemented by completing one or more actions at a 1, 2 or 3-star level, from a list of four to eight actions. These actions are tailored to all Minnesota cities, focus on cost savings and energy use reduction, and encourage civic innovation. This link outlines the Urban Forestry initiative part of the program.

Ash Replacements for Urban and Woodland Plantings
2005 - OSU Ash Alert - In developing this guide for selecting tree species to use to replace ash, it was assumed that, if not for emerald ash borer, one or more of the ash species would be suitable for the planting. Tree species included in this guide, therefore, are generally of the same size as ash and grow well on sites suitable for one or more of the native ash species. You will not, for example, find tree species in this guide that grow to a maximum height of 25 feet and which would be suitable for planting under utility power lines, as ash would not be an appropriate tree for such a planting.
Ash Seed
In response to extensive tree mortality by the EAB, ash seeds are being collected for long term storage to preserve genetic resources of the ash species. This has been a combined effort of the Agricultural Research Service and the Forest Service along with NRCS, BLM, and over 50 cooperators.
