Grapefruit.

This 4-page article written by Ariel Singerman and published by the Food and Resource Economics Department presents the cost of production per acre for growing fresh grapefruit in the Indian River region during 2015/2016, based on a survey of growers conducted at the Indian River Citrus League production committee meeting in mid-July 2016. The cost estimates do not represent any individual operation; rather, their purpose is to serve as a benchmark for the industry. Typical users of these estimates include growers, consultants, property appraisers, and researchers.

Managing the Health and Productivity of HLB-Affected Groves

Citrus groves around Lake Alfred, Florida. Oranges, fruit, trees.

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.

Citrus Flavonoid Effects on Obesity

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.

Evolution of Citrus Disease Management Programs and Their Economic Implications: The Case of Florida’s Citrus Industry

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.

An Overview of the Grapefruit Market in South Korea

According to the Foreign Agricultural Service of the United States Department of Agriculture, worldwide consumption of fresh grapefruit in 2014/15 increased from 4.2 million to 5.2 million metric tons. China, which is the largest producer of grapefruit, was largely responsible for the increase. In South Korea, however, the state of Florida in the United States has traditionally dominated the grapefruit market. The South Korean grapefruit market has been increasing in recent years and is expected to keep growing. The industry in Florida now faces fierce competition from other suppliers with lower import prices and different harvest seasons. This 5-page fact sheet written by Yan Heng, Hyeyoung Kim, and Lisa House and published by the Food and Resource Economics Department aims to provide an overview of the grapefruit market in South Korea and evaluate the potential of this market for Florida fresh grapefruit producers.

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.

Profitability of Citrus Tree Greenhouse Production Systems in Florida

Nurseries are a vital part of the citrus industry in Florida, providing growers with trees for replanting and expanding citrus groves. As part of the response to citrus greening and canker disease in the industry, nursery-aimed regulations were set in place to try to guarantee the production of trees “free of virus or other graft transmittable diseases” in plant nurseries. The new regulations resulted in an important shift for producers from traditional open field groves to greenhouses. This 4-page fact sheet describes an experiment performed at the UF/IFAS Mid-Florida REC in Apopka to test the profitability of different inputs in citrus-producing greenhouse nurseries and provides recommendations that will be useful for the whole citrus-tree-producing sector.
