Citrus is susceptible to a large number of
diseases caused by plant pathogens. Economic losses
due to plant diseases can be severe, but fortunately,
not all pathogens attacking citrus are present in
Florida. Major citrus diseases currently present in
Florida include: Alternaria brown spot, blight, citrus
canker, greasy spot, melanose, Phytophthora-induced
diseases (foot and root rot, brown rot), postbloom
fruit drop (PFD), scab, and tristeza. An exotic,
destructive disease called citrus greening
(Huanglongbing) has recently been found in Florida.
Any exotic diseases, if introduced, will increase
production costs and decrease profitability for Florida
growers. Exotic diseases affect the viability of the
industry or the varieties that could be profitably
grown. Background information for each exotic
citrus disease will be presented in a series of fact
sheets to: 1) provide a basis for evaluating exotic
pathogens that may pose potential risks to Florida
citrus; and 2) create a decision-making framework to
prevent their introduction and spread. This paper will
discuss Citrus tristeza virus-Stem Pitting (CTV-SP) disease
