During the Florida Citrus Industry Annual Conference earlier this month, Tamara Wood, executive director of the Citrus Research and Field Trial (CRAFT) Foundation, gave an update on a new phase of the CRAFT program. Started in 2019, CRAFT was initially focused on new plantings. The program helps growers cover the cost of new plantings if they agree to an experimental …
Speaking at the Florida Citrus Industry Annual Conference in June, Scott Angle, leader of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), reaffirmed the urgency the institution has placed on finding viable solutions to HLB. This includes presenting the citrus industry with a road-map document to lay out UF/IFAS HLB research priorities and objectives. One of the approaches …
The July issue of Citrus Industry magazine focuses on the latest work to breed better citrus trees. Chief among the goals is developing varieties resistant or tolerant to HLB. A trio of articles will give readers an inside look at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) and U.S. Department of Agriculture Agricultural Research Service (USDA …
The Citrus Research and Development Foundation (CRDF) held its June board of directors meeting in conjunction with Florida Citrus Mutual’s Florida Citrus Industry Annual Conference in Bonita Springs. The June gathering is when the CRDF board passes its budget for the next year. The board funded a project by Zhanao Deng, professor of environmental horticulture with the University of Florida …
California Citrus Mutual (CCM) in mid-June welcomed congressional support for critical federal citrus programs. The programs being supported include the Citrus Health Response Program, the HLB Multi-Agency Coordination Group and an additional $1 million in federal funding for a new citrus breeding program. The House Appropriations Committee has included additional funding for citrus breeding research. The research is intended to …
The Florida Citrus Commission (FCC) on June 14 received an update about a program for expedited propagation, in which 23 nurseries are participating. The goal of the expedited tree propagation program is to have several million HLB-tolerant or HLB-resistant trees planted in the next several years. Rosa Walsh, Florida Department of Citrus (FDOC) director of scientific research, provided the update. …
Positive results from experiments with photoselective shadecloth for color break and with plant growth-promoting bacteria for tree health were reported at a June 14 citrus under protective screen (CUPS) seminar. Presenter Arnold Schumann also gave an update on the generous fruit yields being generated in CUPS. Schumann is a University of Florida Institute of Food and Agricultural Sciences Citrus Research …
Highlands County Citrus Growers Association (HCCGA) President Aaron Nelson recently shared observations about trunk injection of oxytetracycline (OTC) for trees with HLB. The first formulations for citrus trunk injection became available in January. His observations follow: Over the course of the last six months there have been countless hours spent injecting millions of trees all over the state. What follows …
Low Brix has been a major problem plaguing the Florida citrus industry in recent years. While many growers are struggling to achieve the minimum required Brix level, this has not been an issue for citrus grower Chip Henry. He recently shared how he believes his organic production techniques contribute to high Brix as well as stopping premature fruit drop in …
The Gulf Citrus Growers Association (GCGA) hosted its annual meeting in Fort Myers in early June to tend to association business and elect new board members. The event was well attended, and growers were mostly in good spirits buoyed by observations that HLB therapies might be having positive impacts on trees. Ron Mahan, current GCGA president, captured that sentiment in …
Florida Grower magazine chose Glenn Beck as the 2023 Citrus Achievement Award winner. He is featured in the magazine’s June cover story. For more than 20 years, the people who have won the award have helped shape the history of the state’s citrus sector. Some years, selecting a winner is an easy process because the person checks so many boxes. …
Fundecitrus researchers contributed to two recent citrus gatherings in South America — the 48th Expocitrus/44th Citriculture Week in Sao Paulo, Brazil, and a CITRIBAC project meeting in Argentina. Researchers Franklin Behlau, Marcelo Miranda and Geraldo Silva Júnior, along with postdoctoral fellows Deived Carvalho and Wellington Ivo Eduardo, gave lectures on citrus-growing topics at the 48th Expocitrus/ 44th Citriculture Week. The …
By Ute Albrecht, Ankit Pokhrel, Sarah Strauss and Ramdas Kanissery The soils in most Florida citrus production areas are sandy. They have less than 1% organic matter and a low cation exchange capacity (CEC). This makes them prone to nutrient leaching, especially after heavy rainfall events in the summer. HUMIC SUBSTANCESOne way to improve soils is by amending them with …
Using drones to apply chemical control for HLB-spreading psyllids in Brazil proved effective against adult insects, a Fundecitrus researcher reported. The researcher, Marcelo Miranda, said psyllid mortality was above 80% as a result of drone applications. Miranda’s work was pioneering in 2021. There was no record of the use of drones for the chemical control of the psyllid in western …
Psyllids collected in orchards in four microregions of Brazil’s citrus belt showed reduced susceptibility to insecticides from the pyrethroid and neonicotinoid chemical groups. That information was reported earlier this year by agronomist and researcher Fernando Amaral of the Arthropod Resistance Laboratory at the Luiz de Queiroz College of Agriculture/University of São Paulo (ESALQ/USP). This was the first confirmation of psyllid …
By Frank Giles HLB has taken a toll on growers both large and small over the years. That’s been the case with third-generation grower Chuck Bellamy, who grows citrus near Inverness, Florida. His grandparents planted the first trees on the property in 1930. A few of those trees are still alive in the grove nearly 100 years later. Bellamy says …
The sting nematode is the most serious nematode problem in young citrus groves, nematologist Larry Duncan reported at the Florida Citrus Growers’ Institute in April. According to Duncan, long before HLB, the sting nematode was widely encountered in groves on Florida’s Central Ridge and in Polk County. The University of Florida Institute of Food and Agricultural Sciences professor said tree …
Hurricanes Ian and Nicole in 2022 caused early fruit drop in the Indian River area, where two studies of 39,000 trees that might tolerate HLB are being conducted. Researchers now expect significant data from the studies will come after the 2023, 2024 and 2025 season harvests, but they have already gained some insights from the projects. The first experimental grove, …
During a historically low period of Florida citrus production, Inverness grower Chuck Bellamy has found a way to keep fruit on his trees. In the June cover story of Citrus Industry magazine, he tells what regenerative practices have reduced fruit drop in his grove. Not only is he keeping more oranges; he has lowered his production costs in the process. …
There has been much focus on the benefits of applications of plant growth regulators like gibberellic acid and 2,4-D, and more recently oxytetracycline hydrochloride to improve the health of citrus trees infected with HLB. Silicon also has been highlighted for its potential benefits to citrus. Mohammad Adnan Shahid, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor, …
