    Insecticide Options for Protecting Ash Trees

    Many homeowners, arborists and tree care professionals want to protect valuable ash trees from EAB. Scientists have learned much about this insect and methods to protect ash trees since 2002. This bulletin is designed to answer frequently asked questions and provide the most current information on insecticide options for controlling EAB.

    Emerald Ash Borer
    Emerald ash borer (EAB), Agrilus planipennis Fairmaire, is an exotic beetle that was discovered in southeastern Michigan near Detroit in the summer of 2002. The adult beetles nibble on ash foliage but cause little damage. The larvae (the immature stage) feed on the inner bark of ash trees, disrupting the tree's ability to transport water and nutrients. Emerald ash borer probably arrived in the United States on solid wood packing material carried in cargo ships or airplanes originating in its native Asia. Emerald ash borer is also established in Windsor, Ontario, was found in Ohio in 2003, northern Indiana in 2004, northern Illinois and Maryland in 2006, western Pennsylvania and West Virginia in 2007, Wisconsin, Missouri and Virginia in summer 2008, Minnesota, New York, Kentucky in the spring of 2009, Iowa in spring of 2010, and Tennessee in the summer of 2010 . Since its discovery, EAB has:

    • Killed tens of millions of ash trees in southeastern Michigan alone, with tens of millions more lost in Illinois, Indiana, Kentucky, Minnesota, Missouri, New York, Ohio, Ontario, Pennsylvania, Tennessee, Quebec, Virginia, West Virginia, and Wisconsin.
    • Caused regulatory agencies and the USDA to enforce quarantines (Michigan, Illinois, Indiana, Iowa, Maryland, Minnesota, Missouri, Ohio, New York, Ontario, Pennsylvania, Tennessee, Virginia, West Virginia, Wisconsin, and Kentucky) and fines to prevent potentially infested ash trees, logs or hardwood firewood from moving out of areas where EAB occurs.
    • Cost municipalities, property owners, nursery operators and forest products industries tens of millions of dollars.

    Cincinnati to use ash trees in urban timber program

    The Cincinnati Parks department is participating in an urban timber program to use hundreds of its over-mature ash trees that are a high safety risk – yet identified as a valuable resource – for urban timber. The uses of these trees not only helps out local schools and libraries, the city is able to generate dollars to replant municipal trees lost to EAB.

    Other economic and environmental aspects of the program are explained in this video, which is a must-see for communities trying to figure out how to deal with EAB in their ash trees.


    New Strategy Being Developed to Deal With Emerald Ash Borer

    • Research is being conducted at universities, as well, to understand the beetle's life cycle and find ways to detect new infestations, control EAB adults and larvae, and contain the infestation.
    • Quarantines are in place to prevent infested ash firewood, logs or nursery trees from being transported and starting new infestations.

    This Web site provides information from Michigan State University, Purdue University, the Ohio State University, the Michigan and Ohio departments of Agriculture; the Michigan, Indiana and Ohio departments of Natural Resources; the USDA Forest Service; the USDA Animal and Plant Health Inspection Service (APHIS); and the Canadian Food Inspection Agency. Our goal is to help you find answers to your questions about EAB. We also provide links to other EAB-related Web sites. Please check this site often because information changes frequently.

    Scientists are studying methods of controlling EAB. The latest information on insecticide evaluations can help homeowners, arborists and landscapers decide if and how they can treat trees for EAB in certain areas in southeastern Michigan.

     

    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 well as knowing the regulations regarding EAB quarantines and eradication strategies for your area. Contact your state department of agriculture for more EAB regulatory information. As more methods of EAB control are developed, more information will be available.
