Plant physiologist Ute Albrecht recently gave a presentation on increased fruit yield and other apparent benefits of injecting the antibiotic oxytetracycline into citrus tree trunks. The University of Florida Institute of Food and Agricultural Sciences researcher also discussed other advantages that trunk injection provides. These advantages include: Precise delivery of materials Elimination of spray drift Reduced risk for worker exposure …
The recent Florida Citrus Industry Annual Conference featured educational presentations on navigating production in an environment where HLB is endemic in groves. Two of those presentations focused on new technology being developed for use in citrus. Two companies, Elemental Enzymes and TJ BioTech, have been collaborating with the Citrus Research and Development Foundation (CRDF) to research their respective products’ potential …
The pros of injecting the antibiotic oxytetracycline (OTC) into citrus tree trunks to combat HLB appear to be numerous, including increased fruit yield, according to scientist Ute Albrecht. On the other hand, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher only discussed one con, but it was a big one. “Trunk injections cause injury, and long-term …

Citrus growers and industry stakeholders gathered in Bonita Springs last week for the Florida Citrus Industry Annual Conference. After being sidelined the previous two years due to COVID-19, the conference drew a record crowd of more than 500 registered attendees. The event, hosted by Florida Citrus Mutual, was packed with educational programming and meetings for various industry groups. The Citrus …
The Citrus Research and Development Foundation (CRDF) Research Management Committee and board of directors recently approved projects for funding. The first CRDF research project has approval for funding of a final year of research by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) to study the lebbeck mealybug and its management. “The Research Management Committee debated this …
Michael Rogers, director of the University of Florida of Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center in Lake Alfred, discussed the recent Florida Citrus Growers’ Institute in the April All In For Citrus podcast. The event drew a good crowd of growers who came to learn about the latest research aimed at HLB. Rogers made …
The Citrus Research and Development Foundation (CRDF) held its April board of directors meeting to hear reports on projects involving 2,4-D, gibberellic acid, brassinosteroids and zinc. According to Rick Dantzler, chief operating officer of CRDF, the foundation is conducting a full-court press to study how these materials can combat fruit drop and improve quality. CRDF staff also presented a proposal …
Growers gathered in Avon Park at South Florida State College for the Florida Citrus Growers’ Institute on April 5. The event, organized by regional citrus Extension agents with the University of Florida Institute of Food and Agricultural Sciences, aims to provide timely research that can be applied in groves today. It also was an opportunity for growers to get updates …
The Citrus Research and Development Foundation (CRDF) had a busy board of directors meeting in March. Rick Dantzler, CRDF chief operating officer, says the board utilized a new approach in seeking and approving research projects during the meeting. “The board advanced a number of research topics through the vehicle of ‘directed research’ where we negotiate with specific scientists who we …
The Citrus Research and Development Foundation (CRDF) governing board on Jan. 25 approved a project aimed at reducing fruit drop by using potassium, zinc, gibberellic acid and the herbicide 2,4-D in different timing scenarios. The funding will allow University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher Fernando Alferez to finish two years of work that CRDF Chief …
The Citrus Research and Development Foundation (CRDF) board of directors met on Sept. 28. Rick Dantzler, CRDF chief operating officer, shared highlights from the meeting. “The primary action was the endorsement of the idea to pull together a group of plant breeders from across the country to help us decide where to invest our funding in plant improvement,” said Dantzler. …
By Ute Albrecht and Leigh Archer Trunk injection is a targeted delivery of materials into the stem or trunk of trees as an alternative to spraying or soil drenching. It is practical for disease and pest management in high-value forest trees and ornamental plants where aerial applications are problematic because of environmental and human health-related concerns. Interest in using the …
By Nabil Killiny and Christopher Vincent The citrus industry has suffered numerous setbacks over the past 20 years because of the devastating effects of huanglongbing (HLB) disease. Many options for controlling the disease are being investigated to make groves as productive as possible under the current HLB pressure. Even small improvements in tree health or yield of diseased trees may …
Ask any Florida citrus grower what the top priority is, and you’ll likely get the same answer: Keeping HLB-affected trees productive and profitable. The April issue of Citrus Industry magazine provides research on production practices aimed to meet this goal. Adjusting the amount of sunlight plants receive has proven to increase citrus tree health and yield. University of Florida Institute …
Researcher. Scholar. Change agent. Nian Wang, a professor at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), has been recognized for all of these roles with an award from the American Phytopathological Society (APS) at its 2020 annual meeting. Wang received the Ruth Allen award, which honors people who have made an outstanding, innovative research contribution that has …
A new University of Florida Institute of Food and Agricultural Sciences Extension document, Antibiotics in Crop Production, was published in May by Leigh Archer, Ute Albrecht and Pamela Roberts. The authors found that the use of antibiotics has resulted in the successful control of bacterial diseases in some crops but not in others. The publication includes research information on antibiotics …
Many growers in recent years have used bactericides in an effort to reduce HLB infection in their groves. University of Florida Institute of Food and Agricultural Sciences researcher Kirsten Pelz-Stelinski reports on use of bactericides to reduce both the bacteria that causes HLB and the psyllids that spread it. In greenhouse studies, she reports, bactericides appeared to offer “some reduction” …
A University of Florida Institute of Food and Agricultural Sciences researcher reports on an experiment to see if treating trees with heat would enhance the uptake of a bactericide commonly used for HLB. “We treated trees that were not HLB infected, so this wasn’t looking at the efficacy of heat treatment against HLB,” says scientist Christopher Vincent, who works at …
By Harold Browning Column sponsored by the Citrus Research and Development Foundation Use of bactericides to reduce disease levels in infected trees continues to be a topic of debate in Florida citrus. Now in the second season of grower use, many growers are continuing to use the three products containing oxytetracycline or streptomycin within their seasonal spray programs. The Citrus …
