What is an Exotic Citrus Disease?

An exotic citrus disease is a disease that does not occur in Florida, but can be found in other major citrus growing regions around the world. This website focuses on five exotic citrus diseases that are of economic importance in other parts of the world and can potentially become established in Florida: Citrus Leprosis, Citrus Tristeza Virus-Stem Pitting, Citrus Variegated Chlorosis, Pseudocercospora Fruit and Leaf Spot, and Sweet Orange Scab. The collection of exotic citrus disease documents on this website provide valuable information on the causal agent, symptoms, and transmission of the diseases. This information can be used as a basis for creating response plans for each of the diseases, as well as educational tools for scouting and identification efforts. Early detection is essential to protecting Florida citrus.
