With the trunk-injection season winding down in Florida groves, growers anxiously await to see positive results in HLB-infected trees. Two oxytetracycline (OTC) products have been approved for use in Florida citrus as HLB treatments. A third OTC formulation expects Environmental Protection Agency approval soon.
Trunk-injection treatments are the focus of the latest All In For Citrus podcast. Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center in Lake Alfred, joins Ute Albrecht, UF/IFAS associate professor of plant physiology, for an in-depth conversation about OTC injections. They discuss what was learned as the first application was made in groves.
Albrecht noted that OTC trunk injection is among the most significant breakthroughs in HLB research since the disease was confirmed in Florida nearly two decades ago. She has been a leading UF/IFAS researcher on OTC usage in citrus. Albrecht said if results in commercial groves mirror that of research trials, the industry could see some significant improvements in tree health and production.
While it is still too early to know for sure, she said there are some encouraging reports that trees are responding. But it will likely be after next season’s harvest before it is fully known just how beneficial the OTC treatments have been.
The podcast takes a deep dive into previous research, best application practices and what’s next when it comes to trunk-injection therapies. While Rogers and Albrecht acknowledge OTC therapy is not the silver bullet, it hopefully serves as a significant bridge to help growers remain viable until a long-term solution is found.
