Sponsored Content Q: There have been questions about the effectiveness of ReMedium TI® injections on early varieties like Hamlins. What have you seen from the data collected this past season? Tom Johnson: The early varieties respond well to ReMedium TI® injection. We received data from a grower that had three separate blocks of Hamlins. Each block was about 70 acres. …
Sponsored Content In this special series, Tom Johnson, owner of TJ BioTech, tackles questions about optimizing trunk-injection applications to treat HLB. Q: Are there any advantages or disadvantages to making a ReMedium TI® Injection in the rootstock or the scion? Tom Johnson: To start, agronomically there is really no difference in a ReMedium TI® injection into the rootstock or the …
Florida growers are well into their second application of oxytetracycline (OTC) trunk injection as the 2023–24 season winds down. The results of the first application made last year are becoming somewhat clearer, but there’s still more to observe and learn about trunk injection. Ute Albrecht, associate professor of plant physiology with the University of Florida Institute of Food and Agricultural …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professors Ute Albrecht, Ozgur Batuman and Megan Dewdney recently wrote Suggested Use Pattern of Injectable Antimicrobials for Huanglongbing (HLB) Management (April 2024). They emphasized that the document is not an official UF/IFAS recommendation but is based on the labels for antimicrobial products ReMedium and Rectify. Some key suggestions in …
The Gulf Citrus Growers Association recently hosted a grower panel at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education Center in Immokalee to discuss experiences and results of trunk injection of oxytetracycline (OTC) to treat HLB. Participating in the panel were Ron English, Florida’s Natural Growers/Ranch 1; David Wheeler, Wheeler Farms; and …

By Frank Giles and Maegan Beatty As growers deployed their first application of oxytetracycline (OTC) via trunk-injection this summer, expectations were high but tempered by the fact the therapy is not expected to turn the massive HLB ship around in just one season. By this fall, after the seasonal cooldown, growers were still reporting generally positive signs from the treatments. …
Some Florida citrus growers decided to start slowly with trunk injection of oxytetracycline (OTC), treating only a small portion of their acreage. Others took a wait-and-see approach, hoping to learn from their peers’ experiences. But Wheeler Farms went all in, treating 100% of their trees with trunk injection. “What we were doing was not working, so we needed to try …
Growers have concluded their first round of injecting their citrus trees with oxytetracycline (OTC) and now are anxiously awaiting the results. So far, trees seem to be responding with larger leaves and fruit, but fruit retention will tell the story if the treatment is moving the needle against HLB. For many years, there was a perception among growers that if …
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 …
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 …
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 …
The Citrus Research and Development Foundation (CRDF) recently issued a report describing some of its projects testing the injection of oxytetracycline (OTC) into trees as an HLB treatment. 1. Lukasz Stelinski and Kirsten Pelz-Stelinski, both of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), are measuring the impact of OTC injection on the Asian citrus psyllid (ACP) …
Alico, Inc. began treating citrus trees in January 2023 with an oxytetracycline (OTC) product via trunk injection as a citrus greening therapy. “Through June 30, 2023, we have treated over 35% of our trees with OTC, which is expected to mitigate some of the impacts of citrus greening and is expected to decrease the rate of fruit drop, as well …
By Frank Giles During the Florida Citrus Industry Annual Conference, Ute Albrecht, a plant physiologist with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), provided an update on her research on the use of oxytetracycline hydrochloride (OTC-HCl) to treat HLB. She began her presentation with some history of OTC-HCl. The compound has been in use since the …
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.

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 …
The Peace River Valley Citrus Growers Association (PRVCGA) hosted growers and industry members on National Orange Juice Day to discuss early experiences with trunk injection of oxytetracycline hydrochloride (OTC-HCl).
