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

Through its county agents, the Cooperative Extension Service gives individuals access to the resources at land-grant universities across the nation. These universities are centers for research in many subjects, including entomology (the study of insects) and agriculture. Each county within the U.S. has an Extension office, which is staffed with agents who work closely with university-based Extension specialists to deliver answers to your questions.

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