When a new tool to manage HLB is discovered, it must be tested in the grove in new varieties or in treatments like trunk injection. During the afternoon of the Florida Citrus Show on March 13, attendees will have the opportunity to tour two experimental groves to see this type of research in action. Attendees will see trunk-injection therapies being …
By Ute Albrecht, Carol Tardivo, Gabriel Pugina, Larissa Nunes, Jasmine de Freitas and Gerardo Moreno Since the approval of oxytetracycline (OTC) injection to manage citrus greening (huanglongbing, HLB) in Florida, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) plant physiology team at the Southwest Florida Research and Education Center (SWFREC) has completed various research trials with multiple …
Recently, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) reported research on the development of a new type of citrus tree that can fight off the HLB-spreading Asian citrus psyllid (ACP). The genetically modified tree has only been tested in the lab and the greenhouse, but the research looks promising. The approach involves inserting a gene into …
The citrus section in the February issue of Specialty Crop Grower is coming soon. It’s full of features for growers to dive into. First up is part two of results from the Florida Citrus State of the Industry Survey. (See part one here.) Learn out what percent of growers say they are replanting and how many are participating in the …
After being postponed this fall due to Hurricane Milton, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted its annual Citrus Nutrition Day on Jan. 22 at the Citrus Research and Education Center (CREC) in Lake Alfred. The event was well attended and featured several presentations aimed at optimizing citrus nutrition programs in the HLB era. UF/IFAS …
By Lauren Fessler Mathews, Sanju Kunwar, Ana Redondo and Ozgur Batuman Based on numerous research studies conducted by scientists at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), it has been proven that injections of oxytetracycline (OTC) can help to alleviate symptoms caused by huanglongbing (HLB) disease. This treatment is now widely practiced and crucial for preventing …
By Peter Chaires Florida’s citrus industry is well supported by two phenomenal research institutions: University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) and U.S. Department of Agriculture-Agricultural Research Service (USDA-ARS). UF/IFAS provides research and Extension support from its main campus in Gainesville, as well as from its research and education centers and county Extension offices across the state. …
By Fernando Alferez and Saoussen Ben Abdallah The risk of citrus plantings to become infected with HLB is especially high for young trees, which flush frequently and attract more psyllids than mature trees. Individual protective covers (IPCs) are now being increasingly adopted to protect newly planted citrus trees from psyllid colonization. However, even though IPCs effectively protect young trees from …
Scientists at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are testing a new type of citrus tree that can fight off the HLB-spreading Asian citrus psyllid (ACP). The genetically modified tree has only been tested in the lab and the greenhouse but is very promising as a potential solution to HLB. The approach involves inserting a …
The Florida Citrus Show is scheduled for Thursday, March 13, 2025. The event will be held at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center and the U.S. Department of Agriculture (USDA) Agricultural Research Service U.S. Horticultural Research Laboratory in Fort Pierce. The Florida Citrus Show combines educational seminars for both …
The Florida Citrus State of the Industry Survey seeks input from growers on key issues affecting their groves. While not a scientific survey, it has reflected general trends over the years. This year’s survey asked growers to weigh in on major events like the impact of Hurricane Milton and the performance of trunk-injection therapies. HURRICANE MILTON Hurricane Milton made landfall …
Citrus growing is migrating to additional areas in Brazil, such as the Triângulo Mineiro region, the northwest of of São Paulo and Mato Grosso do Sul. For this reason, Fundecitrus began testing insecticides in these areas and observed that some products, to which the HLB-spreading psyllid is often resistant, performed well in the initial evaluation. Fundecitrus researcher Marcelo Miranda said …
By Manjul Dutt, Sheetal Ramekar and Gary England Developing new citrus cultivars, whether through conventional breeding or genetic engineering methods like transgenics or CRISPR is potentially the most viable long-term strategy to combat huanglongbing (HLB). Identifying potential survivor trees — citrus trees that exhibit disease tolerance in areas with endemic HLB — can also serve as a useful strategy for …
By Peter Chaires As fall approached and Hurricane Milton was not yet on the radar, growers were quietly discussing promising results from oxytetracycline (OTC) therapy. As one would expect, results are as variable as the products, methods of application and factors in the field. However, the view from 40,000 feet was encouraging. Growers not only reported positive observations in their …
The U.S. District Court for the Northern District of California recently ruled that genetically engineered (GE) organisms must be regulated. The ruling overturns a 2020 rule overhaul by the first Trump administration that had eliminated most government oversight over GE crops, trees and grasses. Genetic engineering is one of several routes researchers are taking to breed a citrus tree resistant …
By Ute Albrecht, Gabriel Pugina and Caroline Tardivo Two years have passed since trunk injection of oxytetracycline (OTC) was approved for HLB management in Florida. Many growers have adopted this technology. While most reported positive responses, others did not. The plant physiology team at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center in Lake Alfred recently hosted an OJ Break and Fruit Display. The Dec. 18 back-to-back events were well attended. Ariel Singerman, UF/IFAS citrus economist, presented his research during the OJ Break. One area he addressed was crop insurance adoption among growers. Singerman shared a …
There’s been much talk about the “tree of the future” in the Florida citrus industry. That’s a tree with the trifecta of HLB-resistance, great quality and strong yield. So far, that perfect combination has not been found. But the search is on. This was a topic of discussion during the December episode of the All In For Citrus podcast. Michael …
Citrus Industry subscribers will now receive their magazine content inside of Specialty Crop Grower. The new home for Citrus Industry begins with the January issue of Specialty Crop Grower magazine, available in print and digitally. On the cover of the January issue of Specialty Crop Grower is a face familiar to many in Florida’s citrus community. Jim Snively of Southern …
Researchers with Brazil’s Fundecitrus discussed HLB-related topics at the recent 15th International Citrus Conference in South Korea. Fundecitrus’ Franklin Behlau participated in the section of papers related to HLB, also known as citrus greening disease. Most of the papers provided updates on the disease situation in different locations, including Florida, China, India, Nepal, Indonesia, Iran and Brazil. Behlau discussed the …
