The Citrus Research and Development Foundation (CRDF) board of directors invited six full proposals on combining other antimicrobials with oxytetracycline hydrochloride (OTC-HCl) during its April meeting. “If growers are going to pay the labor costs for workers to crawl underneath a citrus tree to treat it with OTC-HCl, maybe there are other things that could be mixed with the injection,” …
The Florida Citrus Growers’ Institute, presented by the University of Florida Institute of Food and Agricultural Sciences, was held in Avon Park on April 4. The annual educational event drew a good crowd of growers and allied industry. After nearly two decades of fighting HLB, and more recently fallout from hurricanes, those in attendance expressed a renewed sense of optimism …
By Ute Albrecht Replicated field studies have demonstrated positive effects of oxytetracycline administered by trunk injection to manage HLB. In October 2022, a 24(c) special local need label was approved that allows the use of this technology in Florida, and final clearance was given in January. When practicing trunk injection, it is important to do so properly and to be …
Rectify, AgroSource, Inc.’s 95% oxytetracycline hydrochloride-based tree-injection product, is expected to be available for use against HLB in Florida citrus as early as Feb. 24. The product will be available to growers through existing commercial agricultural product distributors. AgroSource petitioned and received a Special Local Needs (SLN) approval for Rectify by the Florida Department of Agriculture and Consumer Services (FDACS) …
Some Florida citrus growers have recently started oxytetracycline hydrochloride (OTC-HCl) injection into tree trunks to help manage HLB. Other growers are considering it. Researcher Ute Albrecht offered a list of best practices for the product’s use during a Jan. 31 presentation in Immokalee. The presentation was made at the University of Florida Institute of Food and Agricultural Sciences Southwest Florida …
Although trunk injection of oxytetracycline hydrochloride (OTC-HCl) has received much recent press for its promise in managing HLB, there is still no silver bullet for the devastating disease. That was part of plant pathologist Ozgur Batuman’s message at a Dec. 10 seminar addressing HLB and other citrus diseases that may exacerbate HLB’s effects on trees. “There is no single effective …
The Gulf Citrus Growers Association (GCGA) hosted a luncheon on Dec. 7 at the Southwest Florida Research and Education Center featuring a presentation by Tom Johnson, chief executive officer of TJ BioTech. The company is the manufacturer of ReMedium TI, the widely discussed formulation of oxytetracycline hydrochloride (OTC-HCI) that has shown promise as a treatment for HLB. The product is …
Trunk injection of oxytetracycline (OTC) has been proposed as a means to manage HLB in citrus. University of Florida research shows OTC injections increase yield and fruit quality but cause tree injury. TJ BioTech expects to receive EPA registration in late fall of this year for an OTC product that could be injected into trees. Florida citrus industry growers and …
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 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 …
There are many materials that will kill the bacteria (Candidatus Liberibacter asiaticus) that causes HLB. The challenge has been getting these materials to the place where the bacteria lives in citrus trees — the phloem. Some believe trunk injection might do the trick, but it is an expensive and labor-intensive practice that has limited any breakthroughs so far. During the …
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 …
A presentation titled “Trunk Injection: Difficulties and Considerations” is one of the first from the cancelled 2020 Florida Citrus Growers’ Institute to become available online. The annual event was cancelled because of COVID-19. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) is working to make additional presentations that were intended for the Florida Citrus Growers’ Institute available …
Since 2016, federal authorities have allowed Florida citrus growers to spray oxytetracycline solutions on their trees to combat citrus greening disease. A newly published University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) study suggests that the bactericide would be more effective if it were injected into citrus tree trunks, a practice not currently approved under U.S. law. Citrus …
Citrus and specialty crop growers will have a great opportunity this summer to gather, learn and connect at the Citrus & Specialty Crop Expo. The event is set for Aug. 12–13 at the Caloosa Sound Convention Center in Fort Myers. The annual Expo brings together citrus and specialty crop producers for two days focused on practical education and valuable industry …
The Citrus Industry section of the April 2026 issue of Specialty Crop Grower highlights ongoing efforts to strengthen Florida’s citrus sector amid challenges. Articles this month showcase education, nutrient management and variety development. A recap of the Florida Citrus Show details a successful March event in Fort Pierce that combined education with a lively tailgate-style trade show. Growers Daniel Hunt, …
According to Saunders Land’s annual Lay of the Land Market Report, there were 79 Florida citrus land transactions in 2025 totaling 20,352 acres. Pricing ranged from $3,936 to $56,003 per acre.

Growers have always been innovators, testing new production practices in their groves. When you add a disease like HLB, those experiments get ramped up in the effort to seek solutions. A good example of this was a discussion that began last year among growers that ascorbic acid (vitamin C) might be helpful in extending the effectiveness of the oxytetracycline (OTC) …
