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.
