As Florida citrus growers look to recover from the damages of Hurricane Irma and continue to cope with citrus greening, University of Florida (UF) scientists suggest using a complete and balanced nutrient program in their groves. “Mineral nutrition plays a vital physiological role in the growth and development of a plant and as well as in plant-defense response,” said Tripti …
From nutritional supplements to managing irrigation to grower outreach and education, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers are finding additional ways to support Florida citrus growers in their fight against citrus greening disease. Twelve projects were funded by the state legislature-funded Citrus Initiative program in 2017-2018 that looked at possible short- and long-term solutions that …
By Brenda Eubanks Burnette I was in Fort Pierce recently doing interviews for an oral history project and ran across some interesting photos and information on O.C. Minton, who was inducted into the Florida Citrus Hall of Fame in 1982. A hard worker who was totally dedicated to the Florida citrus industry, Minton’s defining moments came when fighting for identification …
By Marshall Hartley At Florida Southern College, I remember doing an experiment using a large washtub with holes in the bottom. We filled the tub with very dry sand and then poured 1 inch of water over the sand and let it soak in. The water did not travel through the sand evenly. Instead, the water would find one area …
By Arnold Schumann, Laura Waldo, Davie Kadyampakeni, Rhuanito Ferrarezi and Chris Oswalt Florida citrus trees may require irrigation throughout the year due to the extremely sandy soils with low water-holding capacities, and the warm subtropical climate with distinct drought periods in spring. A soil water sensor system can provide the most reliable data for effective citrus irrigation scheduling in these …
Jim Snively, vice president of grove operations for Southern Gardens Citrus, discusses planting density and technology that may hold promise for coping with HLB. Tree density trials were planted in 2012 at Southern Gardens. After six years, the best results have come from trees planted at about 363 trees per acre, Snively reports. “Everything we’re doing today, we try to …
An Indian River-area grapefruit grower told the crowd at Florida Citrus Mutual’s recent annual conference about his company’s plans for coping with HLB. The plans include replanting with some diverse citrus varieties at higher densities, said Daniel Scott, vice president of Scott Citrus Management. Grapefruit has for the most part proven extremely difficult to grow profitably in the face of …
Growers discuss lessons learned from Hurricane Irma, replanting plans, grove rehabilitation, crop insurance and more. By Tacy Callies Florida citrus growers awaiting Hurricane Irma federal aid and insurance payouts are doing their best to keep crops healthy until more money is available. Paul Meador, citrus grower and head of Everglades Harvesting & Hauling in LaBelle, took a big hit from …
Growers can use these tips and tools for trees impacted by HLB and Hurricane Irma. By Davie Kadyampakeni, Kelly Morgan, Mongi Zekri, Rhuanito Ferrarezi, Arnold Schumann and Thomas A. Obreza Water is a limiting factor in Florida citrus production during the majority of the year. This is because of the low water-holding capacity of sandy soils resulting from low clay …
Beck Brothers Citrus of Winter Garden, Florida, is one of five winners of the Fertilizer Institute’s 4R Advocate Award for 2018. The company is the third winner from Florida and the first citrus grower to receive this national award. Beck Brothers was recognized for implementing 4R fertilizer management practices on the farm to increase production and reduce environmental impact. 4R …
By Rhuanito S. Ferrarezi, Alan L. Wright, Kelly T. Morgan, Philip A. Stansly, Monica Ozores-Hampton and Robert Ebel Huanglongbing (HLB) or citrus greening is endemic in Florida, resulting in billions of dollars of losses since the state’s first detection in 2005. The disease induces visual symptoms in leaves and branches, while severely impacting citrus fruit yield and quality. Fibrous root …
A grower nutrition survey reveals production practices for successful HLB management. By Tripti Vashisth and Christopher Vincent These days, in nearly every conversation about HLB, mineral nutrition comes up in some way. It seems that in a conversation between three people, there will be about four opinions on what, why, where and how to provide nutrition to citrus trees in …
By Ute Albrecht and Sarah Strauss Recent years have seen an explosion of products termed “biostimulants” as alternatives to traditional chemical products to improve plant growth and productivity, and to enhance the sustainability of agricultural systems. Although there is currently no legal definition of biostimulants, they are usually defined as “substance(s) and/or microorganisms that when applied to plants or the …
The November 2017 issue of Citrus Industry magazine features an in-depth article on the first citrus crop forecast of the season. The figure of 54 million boxes of Florida oranges that the USDA predicted was met with mixed reactions and caused some controversy.

By Beverly James, Alec Richman, Brad Buck, Samantha Grenrock and Tom Nordlie The year was 1917. In April, the United States entered World War I. Florida’s population was fast approaching 1 million, and agriculture was the state’s most important economic driver. Citrus cultivation, introduced to Florida 400 years earlier by Spanish explorers, had spawned an industry following the Civil War. …
Imagine camping in the deep woods. You’d want a tent with mesh that prevents bugs – even those as small as gnats – from entering into your wildlife hangout. That’s the idea behind citrus under protective screens, or CUPS, which helps keep away a pinhead-sized insect that causes citrus greening, University of Florida/Institute of Food and Agricultural Sciences (UF/IFAS) scientists …
By Arnold Schumann and Laura Waldo Florida citrus trees may require irrigation throughout the year due to the extremely sandy soils with low water-holding capacities and the warm subtropical climate with distinct drought periods in spring. Citrus trees are evergreen and may be actively growing at any time, with no true dormant phase. HLB-affected trees are particularly prone to multiple …
By Tacy Callies With the recent birth of the Georgia Citrus Association (GCA), many small commercial citrus groves are getting started in the state. Georgia’s newest citrus planting, however, is not a commercial grove. It’s a 100-tree installation that was planted this spring at the Mitchell County Correctional Institute. Dubbed MitCo Grow by a 4-H student, the project is the …
By Mongi Zekri, Bob Rouse and Jonathan Crane Hurricane preparation for citrus growers this year is the same drill as every year. Each year, growers look forward to the rainy season to help their young trees grow fast and their mature trees produce good crops. This year, growers will be praying for good distribution of rains following a year of …
Severe pruning combined with enhanced foliar nutrition did not prove cost-effective. By Monica Ozores-Hampton, Fritz Roka, Robert Rouse and Pamela Roberts Citrus trees affected by huanglongbing (HLB) become diminished, weak and develop dieback resulting in reduced production. Decline in fruit yield ultimately prevents economically acceptable commercial citrus production. Pruning and spraying foliar nutritionals are two practices being considered to restore …
