How to Identify Pest & Disease Problems

Emerald Ash Borer

To properly diagnose a pest or disease problem begin by contacting the Cooperative Extension Service in your county or parish.

Your local Cooperative Extension agent is the best source for assistance with home gardening pest and disease questions. With the help of volunteer Master Gardeners, your County Cooperative Extension can quickly answer most inquiries about plant health care and local conditions. Extension specialists are also available to perform pest and disease diagnosis for homeowners and professionals—including certified arborists, nursery growers, landscapers, and orchardists.

Our online Tree Health Guide provides immediate access to a network of professional arborists, foresters, and Cooperative Extension Service agents to provide effective best management practices for insect problems and plant diseases.

You can also get help and answers to your questions from other tree planters and professionals in our online forum.
