Citrus growers are invited to tour the 20-acre Millennium Block at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center (IRREC) in Fort Pierce on Nov. 7. The tour will be held from 9 a.m. to 2 p.m. New varieties in the grove are in their fourth year of growth. Researchers are …
By Ariel Singerman Citrus growers in Florida are now allowed to inject their trees with oxytetracycline (OTC) to try to control Candidatus Liberibacter asiaticus and/or suppress citrus greening. The use of OTC is expected to improve the trees’ health and, in turn, increase yield. In this article, cost estimates are used to address the question of what yield response is …
As the new citrus season gets underway in Florida, growers are hopeful for an improved harvest. The initial U.S. Department of Agriculture forecast for 2023–24 calls for a 30% increase in the state’s orange crop. The November issue of Citrus Industry magazine has details on the forecast and other good news for growers. In the issue’s cover story, Wheeler Farms …
By Davie Kadyampakeni and Megan Dewdney The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) conducted a six-year project to determine if plant nutritional fertilizer sources coupled with specific crop protection chemicals help mitigate citrus diseases. This project was conducted on a 5-acre commercial citrus grove block near the Citrus Research and Education Center (CREC) in Lake Alfred. …
Many people believe genetics will be the eventual key that unlocks more permanent solutions to HLB. Whether it be traditional breeding or new technologies, one day there could be a citrus tree that is resistant or tolerant enough to make the disease a non-factor. One such key could be CRISPR technology to deliver a tree that is engineered to resist …
By Christopher Vincent, Yu Wang and Nabil Killiny Mild shade reduces stress, increases growth and yield, and may improve pest management under huanglongbing (HLB). It reduces high temperature and water stresses. Shade also may reduce HLB transmission by making trees less visible to Asian citrus psyllids (ACP). Shaded trees have less ACP, and shade appears to reduce the severity of …
In a virtual presentation, plant breeder Jude Grosser discussed recently released citrus varieties that might work well in the fresh fruit market. Grosser is a professor at the University of Florida Institute of Food and Agricultural Sciences’ (UF/IFAS) Citrus Research and Education Center. Here’s a look at some of the varieties he addressed: MANDARINSGrosser described Marathon as the “best option” …
By Ute Albrecht The German scientist Paul Ehrlich pioneered the research for “magic bullets” — chemicals that could kill a microorganism but did not harm the patient. He also coined the term “chemotherapy” and paved the way for developing synthetic drugs. The first synthetic antibiotic (the first sulfa-type antibiotic) to successfully treat human bacterial diseases without major side effects was …
Citrus breeders at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) have been making a big push for four years to develop new orange varieties for processing. The need for the push was accentuated last year by a multitude of adverse situations on the processing side of the business. In a recent virtual presentation, UF/IFAS plant breeder …
The Florida Department of Citrus held a research and budget workshop on Oct. 4. Rosa Walsh, director of scientific research, presented an overview of the general funds received for research this fiscal year along with several possibilities for use of these funds for feedback from the Florida Citrus Commission (FCC). Walsh reported that $1.65 million was received in general revenue …
By Ute Albrecht and Leigh Archer Trunk injection is an alternative technique for applying crop protection materials. This technology has now been approved to deliver oxytetracycline (OTC) for huanglongbing (HLB) management in Florida. Injections cause injury, and best practices need to be established to minimize injection-induced tree damage. University of Florida Institute of Food and Agricultural Sciences researchers (UF/IFAS) injected …
The Citrus Research and Development Foundation (CRDF) approved three new projects during its September board of directors meeting. The projects will test the injection of different antimicrobial materials to treat HLB. One project will be managed by Ozgur Batuman, a citrus pathologist with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Another will be run by Kranthi …
The Wedgworth Leadership Institute for Agriculture and Natural Resources (WLI) recently selected 30 participants for Class XII of its two-year leadership development program. The program’s first seminar will take place in Gainesville in November. Participants have committed to 11 seminars, totaling 55 days, which further develop their leadership capacity in representing agricultural and natural resources industries. Seminars will be held …
Later this month, Florida citrus fruit displays will get underway. This is a key component of the citrus breeding program to get input from growers and other industry stakeholders on how fruit from potential new varieties looks and tastes. During the September All In For Citrus podcast, Michael Rogers, director of the University of Florida Institute of Food and Agricultural …
By Fernando Alferez, Daniel Boakye, Murillo De Sousa and Pablo Orozco After HLB was first detected in Florida, increase in disease-associated preharvest fruit drop in affected trees has significantly reduced grower returns. Fruit drop is normal in healthy citrus, accounting for 10% to 15% of the total crop. However, under endemic HLB conditions and depending on the variety, crop loss …
By Ozgur Batuman Plant virus diseases are unusually difficult to manage if introduced into new production sites. Citrus-infecting viruses, particularly those spread by insect vectors, are no exception to this. Florida is regularly challenged by a barrage of invasive pests and pathogen species that could devastate the citrus industry. Viruses causing citrus leprosis and citrus yellow vein clearing diseases are …
Using the plant growth regulators (PGRs) gibberellic acid (GA), 2,4-D and cytokinin in combination can maximize the benefit for HLB-affected trees, researcher Tripti Vashisth reported recently. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor of citrus horticulture and production works at the Citrus Research and Education Center in Lake Alfred. She discussed the benefits of …
Trunk injection of oxytetracycline (OTC) is giving growers hope for the future of the Florida citrus industry. Many are optimistic the new therapy will help improve both fruit quality and quantity. The key will be whether fruit holds on the trees until harvest time. The October issue of Citrus Industry magazine provides the latest information on OTC trunk injection from …
By Ute Albrecht, Larissa Nunes and Gabriel Pugina The current label recommends trunk injection of oxytetracycline (OTC) into the rootstock, but this may not always be possible. Previous University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) studies have shown that both rootstock and scion injections are effective. However, researchers have not yet studied if different rootstocks influence …
By J. Scott Angle, jangle@ufl.edu, @IFAS_VP Citrus has the attention of new University of Florida President (UF) Ben Sasse. That bodes well for UF’s continued commitment to the industry. Ag TourIt started on June 3, when I took the president on a 28-hour tour of Florida agriculture. It included a stop at the Southwest Florida Research and Education Center in …
