Tree Healthcare Encyclopedia

Our arborists compiled an encyclopedia of how to care for a variety of tree pests and diseases. Common pests and diseases found on a variety of trees and plants are listed below.

The list is organized according to the host plant genus. The pesticide products recommended appear alphabetically within the tables and does not constitute a preference ranking. If no product is listed in the compendium, either a pesticide application would not be effective, or there is no product for that combination of tree and pest. The “Notes” column contains information on pest biology and monitoring and additional remarks for tree care.
