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.

Muestreo por Golpeo para el Psilido Asiatico de los Citricos (PAC). Hoja de campo
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.

Cost of Production for Processed Oranges in Central Florida (Ridge), 2014/15
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.

Suggested Weed Control Programs for Citrus
Weed management is an important component of citrus production. The selection and implementation of a weed management program can lead to both economic and environmental returns. This three-page fact sheet details how to manage weeds in both young and mature groves, the differences in weed control programs between interior areas and coastal or flatwoods areas, how to control weeds after a freeze, and common ways that herbicides are misused. Written by Stephen H. Futch and Brent Sellers, and published by the Horticultural Sciences Department.

2014/15 Picking, Roadsiding, and Hauling Charges for Florida Citrus
As Florida’s citrus industry confronts the impacts of Huanglongbing (HLB or citrus greening)–decreasing crop yields and production, lower quality fruit, and increasing cost of production–many growers are facing declining returns. A 2015 survey of twelve Florida citrus harvesters to collect data on harvesting charges during the 2014/15 season revealed that average picking and roadsiding charges for fresh fruit are in most cases lower than those for processed fruit, likely because of the impact of HLB. This 3-page fact sheet written by Ariel Singerman of UF/IFAS Citrus Research and Education Center and published by the Food and Resource Economics Department presents the results of the survey and provides a table summarizing the harvesting charges for citrus during the 2014/15 season with the average and the range of picking and roadsiding charges by variety and type of fruit (fresh versus processed), as well as the average hauling charges for all varieties by distance. The fact sheet will assist growers in the effort to compute the changes to their economic returns as the industry adapts to remain profitable.

What Is the Economic Benefit of a Citrus Health Management Area? A Case Study
A Citrus Health Management Area (CHMA) is a group of growers who work cooperatively to coordinate insecticide application timing and mode of action in order control the insect vector of citrus greening disease. CHMAs help prevent insect vectors from moving between groves and reduce the likelihood that insects will develop pesticide resistance. This 3-page fact sheet written by Ariel Singerman and Brandon Page and published by the Food and Resource Economics Department analyzes the case-study data on yields of Valencia oranges from blocks located in two different categories of CHMAs to find the impact of citrus greening disease on citrus yields and provide evidence on the effectiveness of best class CHMAs as a way to deal with the disease. The analysis provides evidence that CHMAs can enhance an individual grower’s profitability at a time when margins are becoming increasingly narrow.

Maximizing Weed Control in Florida Citrus
With Florida citrus growers and production managers being “squeezed” between rising production prices and declining yields from citrus greening, there’s more call than ever to reduce citrus production costs. Controlling weeds is a major expense, amounting to 11% of the total $2,278 annual production cost per acre for the 2014–2015 season. This 3-page fact sheet teaches the six essential components of an effective weed-management program to help maintain the profitability of this vital Florida industry. Written by Stephen H. Futch and Brent Sellers and published by the Horticultural Sciences Department. http://edis.ifas.ufl.edu/hs237
Resetting in Citrus Groves
To maintain the overall productivity of a citrus grove, dead or declining trees should be promptly removed and replaced with young, healthy trees, a practice known as resetting. Resetting presents many challenges for growers because young trees require more attention and care than more established trees. This 4-page fact sheet discusses effective resetting methods and maintenance for citrus. Written by Zekri Mongi, and published by the UF Department of Horticultural Sciences, August 2015.

The front of this identification sheet includes images of healthy and infested roots and descriptions of leaf and root symptoms. The back lists sampling procedures: soil collection, soil testing, and diagnosing phytophthora. Written by Jamie D. Burrow, Diane B. Bright, Tim D. Riley, and James H. Graham, and published by the UF Department of Soil and Water Science, July 2015.

Summary of 2013/14 Production Costs for Indian River Fresh Market Grapefruit and Southwest Florida Juice Oranges
This 10-page report, developed through interviews with growers who managed their own citrus groves, outlines the cost of production budgets for fresh grapefruit and juice oranges grown during the 2013/14 season. The Florida citrus industry is on a steep learning curve as it collectively tries to maintain economically sustainable fruit yields from HLB-infected trees. Growers are experimenting with new materials and management strategies to reduce psyllid populations and improve a tree’s overall nutritional health. As a result, production costs have increased threefold since 2004. Between the 2012/13 and the 2013/14 seasons, production costs increased 30% and 34% for fresh grapefruit and juice oranges, respectively. Since 2004, production costs for fresh grapefruit have increased 182%, while costs to grow juice oranges have increased 211%.

Informacion para los propietarios: Cancro Citrico (PP298)
El cancro cítrico es una enfermedad introducida en Florida y es muy perjudicial económicamente para la industria comercial. La enfermedad no está presente en todas las regiones tropicales y subtropicales productoras de cítricos donde el cancro cítrico puede ser problemático, por lo tanto, las restricciones para exportar fruta con cancro cítrico son muy estrictas. Esta enfermedad también concierne a los propietarios, no solo por sus efectos en la industria económica, sino también porque es altamente contagiosa y la mayoría de la fruta contagiada en un árbol muy afectado se cae de éste prematuramente. This 4-page fact sheet was written by M. M. Dewdney, P. D. Roberts, J. H. Graham, K. R. Chung, and M. Zekri, and published by the UF Department of Plant Pathology, January 2013.

Identificacion de los sintomas del cancro citrico y procedimientos de descontaminacion (PP214SP/PP138)
El cancro cítrico es una seria enfermedad de los cítricos. La mayoría de los cultivos de cítricos son susceptibles, la toronja, la lima mejicana y algunas naranjas tempranas son las más susceptibles. Una infección severa puede causar defoliación, una muerte regresiva de la rama, una decadencia general del árbol, una caída prematura de la fruta, y manchas en la misma. Los árboles severamente infectados se vuelven débiles, improductivos y no rentables.
