## What is Citrus Diseases Key?

Early disease detection and management are essential to ensuring continued viability of the U.S. citrus industry. Rapid communication of new diseases, significant outbreaks, and accurate information are vital. Many diseases are difficult to distinguish from one another or disease symptoms mimic disorder symptoms. Images and description of diseases are helpful in making a correct diagnosis.

Citrus Diseases is a symptom-based, illustrated identification key that encompasses citrus diseases that are in the United States as well as those of immediate concern. It is designed to be used by United States quarantine officials responsible for inspecting imports, and by federal, state and local domestic survey and identification personnel.
