While it remains to be seen if trunk injection of oxytetracycline hydrochloride (OTC-HCl) is a game changer in the fight against HLB, it certainly has intensified the conversation about the potential for antimicrobial treatments. There are literally hundreds of materials that might be effective at reducing the HLB bacteria in trees, but it has been a slow process to screen …
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 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). Two new OTC-HCl products, ReMedium TI and Rectify, were registered this season for use as an HLB treatment in Florida citrus. While some growers are taking a wait-and-see approach to trunk …
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,” …
Lukasz Stelinski for years has promoted saving money on HLB control by spraying for Asian citrus psyllids (ACP) only when their populations reach a certain threshold. The University of Florida Institute of Food and Agricultural Sciences professor still promotes that concept, but with a slightly new twist. TRUNK INJECTION SHOWING PROMISEIn a virtual seminar on April 25, Stelinski advised growers …
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 …
The Citrus Research and Development Foundation (CRDF) board of directors convened its March meeting with a busy agenda, addressing fast-moving current events. Discussion focused on newly approved oxytetracycline hydrochloride (OTC-HCl) trunk-injection products currently being applied in groves. The board funded a project to measure the impact of OTC-HCI applications on the Asian citrus psyllid (ACP). Specifically, the study will determine …
Growers have been deploying several new therapies aimed at improving the health of HLB-infected citrus in recent years. Plant growth regulators like gibberellic acid, 2,4-D and brassinosteroids have demonstrated the ability to improve tree health and help in fruit retention. More recently, direct delivery of oxytetracycline hydrochloride (OTC-HCl) via trunk injection has been approved for use in groves. There is …
At the latest Citrus Research and Development Foundation (CRDF) board of directors meeting, funding was approved for a project by Robert Turgeon. He is a professor of plant biology at Cornell University. “Dr. Turgeon is considered by some to be the world’s foremost expert on phloem physiology. If his project succeeds, it could solve our problem with HLB,” CRDF chief …
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 …
The Citrus Research and Development Foundation (CRDF) kicked off the year with its monthly board meeting in January. The board invited three researchers who had submitted pre-proposals to submit full proposals during the meeting. One proposal will study if the ingestion of oxytetracycline hydrochloride (OTC-HCl) will minimize the amount of Candidatus Liberibacter asiaticus (CLas) in the gut of “hot” (or …
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 …
