Citrus canker is a non-systemic bacterial disease that affects citrus trees in both the citrus nursery and in commercial plantings. This poster is designed to assist citrus nursery workers in the identification of citrus canker. This one-page document was written by Jamie Burrow, Megan Dewdney, Ajia Paolillo, and Tim Riley and published by the UF/IFAS Plant Pathology Department.
Microirrigation is an important component of citrus production systems in Florida. For citrus trees, microirrigation is more desirable than other irrigation methods for several reasons: water conservation, fertilizer management efficiency, and freeze protection. Research has shown that when microirrigation systems are properly managed, water savings can amount to as much as 80% compared with subirrigation and 50% compared with overhead sprinkler irrigation. Research has also shown the important advantage of microsprinklers for freeze protection of citrus. This 4-page fact sheet discusses fertilizer solubility and some common fertigation materials. It also offers a fertigation summary. Written by Mongi Zekri, Arnold Schumann, Tripti Vashisth, Davie Kadyampakeni, Kelly Morgan, Brian Boman, and Tom Obreza, and published by the UF Horticultural Sciences Department, September 2017.

After years of extensive research from across the world, we still do not have a cure for HLB; however, we have learned a lot about this disease, the plant’s response to the disease, and the disease vector. Based on scientific and observational information gathered in the last decade, a number of tools and strategies are currently available for growers to maintain the health and productivity of HLB-affected trees. This four-page fact sheet will shed light on these currently available horticultural inputs and practices that can be implemented immediately by growers to maintain and improve citrus tree health.Written by Tripti Vashisth and published by the Horticultural Sciences Department.
A new two-page fact sheet has been published by the Horticultural Sciences Department and the UF/IFAS Citrus Research and Education Center about citrus nutrition management practices. It was written by J.D. Burrow, T. Vashisth, M. Zekri, S.H. Futch, and A. Schumann.
The increased prevalence of obesity in recent decades has sparked tremendous concern worldwide. A type of phytochemical, called flavanoids, has been shown in clinical trials to provide significan benefits to overall health because of their antioxidant abilities. Flavanoids are especially abundant in citrus species. This two-page fact sheets describes the health benefits of citrus flavanoids. Written by Yu Wang and Laura Reuss and published by the Food Science and Human Nutrition Department.
New exotic diseases (citrus canker, HLB, and citrus black spot) have sharply increased the real cost of production of citrus in Florida. Growers have been applying different management strategies, and more effective treatments are being researched. The costs and benefits of these alternatives will need to be quantified to establish their economic feasibility. This 5-page fact sheet written by Ariel Singerman and Marina Burani-Arouca and published by the Food and Resource Economics Department focuses on the costs of managing exotic citrus diseases as they become endemic or established within a citrus industry, with Florida used as an example. The steep increase in the real cost of production of citrus in Florida from 2003/04 to 2014/15 provides evidence that managing endemic exotic diseases is very costly for growers, even without taking into account the effect those diseases have on yields. Therefore, governmental policies focused on preventing the introduction of additional exotic diseases would be highly beneficial for citrus growers and the Florida citrus industry as a whole.
This 4-page fact sheet written by Ariel Singerman and published by the Department of Food and Resource Economics presents the cost of production per acre for processed oranges in southwest Florida during 2015/16. Thirteen growers participated in the survey and provided annual, per-acre costs by program for a “typical” irrigated, mature grove (10+ years old), including resets. The number of acres managed by their combined operations accounts for approximately 41,000 acres, of an estimated 257,298 acres devoted to oranges in the area, so the sample represents 16% of the acreage devoted to oranges in that region. Typical users of the estimates in this publication include growers, consultants, property appraisers, and researchers.
This 4-page fact sheet written by Ariel Singerman and published by the Department of Food and Resource Economics presents the cost of production per acre for processed oranges in central Florida during 2015/16. Five growers participated in the survey and provided annual, per-acre costs by program for a “typical” irrigated, mature grove (10+ years old), including resets. The number of acres managed by their combined operations accounts for approximately 29,000 acres, of an estimated 137,154 acres devoted to oranges in the area, so the sample represents 21% of the acreage devoted to oranges in that region. Typical users of the estimates in this publication include growers, consultants, property appraisers, and researchers.
The United States is the world’s largest producer of blueberries. Florida’s blueberry production represents a small fraction of total US production, but blueberries are nevertheless an important and valuable crop in the state because Florida growers benefit from the nation’s earliest market window. In fact, the average price for blueberries received by growers in Florida during the last three years was 2.5 times the US average.
This 15-page fact sheet written by Ariel Singerman, Marina Burani-Arouca, Jeffrey G. Williamson, and Gary K. England, and published by the UF Department of Food and Resource Economics provides a summary of the enterprise budget developed for highbush blueberry production in Florida. The budget represents a typical operation and serves as an economic benchmark for growers, providing estimates of expenses and potential estimates of revenue and profit for a blueberry crop to help current and potential blueberry growers make informed decisions about blueberry production.
A survey of Florida citrus harvesters was conducted in July 2016 to collect data and estimate the harvesting charges to Florida citrus growers during the 2015/16 season. This 5-page fact sheet written by Ariel Singermam, Marina Burani-Arouca, and Stephen H. Futch and published by the UF Department of Food and Resource Economics presents the results of the survey, summarizing the harvesting charges for citrus during the 2015/16 season and documenting the changes in harvesting costs as the impact of HLB increases across the state. The estimates presented provide the basis for computing on-tree prices from delivered-in prices, thus allowing the computation of the change in citrus growers’ economic returns as the industry adapts to remain profitable.

A survey of Florida fresh citrus packers was conducted in April 2015 to collect data on their packing charges during the 2014/15 season. A total of sixteen packinghouses participated in the survey, seven from the Interior region and nine from the Indian River region. The average of their responses was computed to obtain the estimates presented in this 4-page fact sheet was written by Ariel Singerman, and published by the UF Department of Food and Resource Economics, March 2016.

This field sheet provides information on Tap sampling for Asian Citrus Psyllid (ACP). Monitoring ACP populations is an important tool in the integrated management of citrus greening. The most efficient way to estimate field populations of this insect is by monitoring adults. Tap sampling has proven to provide data needed to make informed decisions for managing this insect pest. This two-page field sheet is the Spanish version of IN1116 TAP Sampling for Asian Citrus Psyllid (ACP) Field Sheet. Written by Phil Stansly, and published by the Entomology and Nematology Department.
UF/IFAS researchers collected data from five growers to estimate the cost of production per acre for processed oranges in central Florida during 2014/15. The cost estimates in this 4-page fact sheet written by Ariel Singerman and published by the Food and Resource Economics Department do not represent any individual operation. Instead, their purpose is to serve as a benchmark for the Florida citrus industry. Typical users of these estimates include growers, consultants, property appraisers, and researchers.
