The authors' intent is to: 1) provide a basis for evaluating exotic pathogens that may pose potential risks to Florida citrus; and 2) to create a decision-making framework to prevent their introduction and spread. This paper will discuss citrus black spot. This document is Fact Sheet PP-213, one of a series of the Plant Pathology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida. Publication date: September 2005.

Sweet Orange Scab is a disease that differs in host ranges from the common citrus scab present in Florida. Citrus scab is serious on many tangerines and tangerine hybrids such as Temple, as well as grapefruit and lemons, but rarely causes lesions on sweet orange. In contrast, SOS can cause significant damage on all sweet oranges as well as tangerines and their hybrids. It can be a significant problem on fruit produced for fresh market. Establishment of SOS in Florida could also have quarantine implications for marketing of fresh fruit, especially in Europe. SOS is common in humid citrus growing areas of South America (Argentina, Bolivia, Brazil, Ecuador, Paraguay, and Uruguay), but its presence has not been confirmed elsewhere. This document is Fact Sheet PP-224, one of a series of the Plant Pathology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida. Publication date: November 2005.

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. There are other serious, exotic pathogens that have not been introduced into Florida. This paper will discuss Huanglongbing (HLB), also commonly called citrus greening. This document is PP-210, one of a series of the Plant Pathology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida. Original publication date June 2005.

Millions of boxes of fruit and thousands of acres of citrus trees have been lost in freezes and frosts. Oranges are usually damaged when the fruit are exposed to temperatures of 28°F or lower for 4 hours or more. As the temperature gets colder or durations below 28°F get longer, damage to fruit, leaves, twigs, and eventually large branches increases. More than nearly any other factor, freezes have caused some of the most dramatic changes in fruit supply, availability, and price. Thus, any method that provides some cold protection can be of major importance to citrus growers. This document is Fact Sheet HS-931, one of a series of the Horticultural Sciences Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

Mechanical harvesting and many other improvements in harvesting of Florida citrus have their origins in the mid-1950s. During the 1950s and 1960s, a consistent labor supply for hand harvesting was becoming increasingly difficult to obtain and acreage along with yields of Florida citrus was steadily increasing. These concerns led to the development of a citrus mechanical harvesting program spearheaded by the Florida Department of Citrus, United States Department of Agriculture and the University of Florida. The program sought to develop harvesting systems to remove or aid in the removal of fruit from the trees, thereby reducing the number of hand harvestors needed. Industry interest in mechanical harvesting decreased in the 1980s when the devastating freezes of 1983, 1985 and 1989 decreased acreage and volume of fruit to be harvested. This document is HS-1017, one of a series of the Horticultural Sciences Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.
