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 …
By Tripti Vashisth Since 2021, a number of Florida growers have adopted the use of gibberellic acid (GA) in their grove management programs. This widespread adoption is due to the fact that GA-treated trees show canopy rejuvenation and reduction in preharvest fruit drop, resulting in improved yields. The research on Valencia shows that the effect of GA improves over time. …
In the latest episode of the All In For Citrus podcast, Tripti Vashisth discusses the citrus flower bud advisory system. The service is provided by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). The advisories on flowering generally start before Thanksgiving and run through the end of February or early March. “The goal of the flower bud …
By Tripti Vashisth, Faisal Shahzad and Jamie Burrow Leaf nutrient analysis is an important part of a successful citrus management program. Good fertilization practices are critical for optimal crop production, especially in HLB conditions. The two main objectives of nutrition management in citrus are 1) optimum and consistent yield and 2) building a strong tree that grows and produces year …
Plant Diagnostic Center Director Raj Singh at the Louisiana State University Agricultural Center (LSA AgCenter) recently addressed two stresses that impact yields in Louisiana citrus — internal dry rot and puffy fruit. INTERNAL DRY ROTMature fruit affected by internal dry rot may look healthy on the outside, but peeling the fruit reveals dry, discolored flesh. This internal dry rot is …
By Ramdas Kanissery Florida citrus growers face weed management problems throughout the year because of conditions that favor rapid weed growth in groves. A weed-free tree row is desired in a citrus grove to minimize weed competition with trees. Hence, chemical weed control using post-emergent, systemic herbicides like glyphosate has become a vital production practice in the Florida citrus industry. …
The second 2022–23 orange crop forecast update for the São Paulo and West-Southwest Minas Gerais citrus belt, published on Dec. 12 by Fundecitrus and its cooperators, is 314.11 million boxes of 40.8 kilograms each. This update indicates that the crop remains within expectations in relation to the projected forecast in September, with an increase of only 20 thousand boxes, which …
The Florida citrus industry has an urgent need for disaster aid in the wake of Hurricanes Ian and Nicole, 17 members of Florida’s congressional delegation advised the U.S. House Committee on Appropriations. In a Dec. 8 letter, the U.S. representatives stated that Hurricane Ian impacts caused an estimated $675.5 million in preliminary damages to the industry. They reported that damage …
The first federal citrus crop forecast to take into account damage from September’s Hurricane Ian dropped Florida’s projected orange crop for 2022–23 to 20 million boxes. That’s 29% below the initial forecast of 28 million boxes in October, 51% less than last season’s final production of 41.05 million boxes and the lowest orange forecast in many decades. Florida’s non-Valencia and …
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 …
By Thomas H. Spreen The timing of Hurricane Ian is not unlike that of Hurricane Irma in September of 2017 in that it struck before the U.S. Department of Agriculture (USDA) crop forecast was released in October, but after the data collection process was already completed for the forecast. Therefore, the USDA forecast will not take Hurricane Ian’s impacts into …
In the search for ways to survive citrus greening, some growers have chosen the citrus under protective screen (CUPS) system as their solution. While CUPS can be costly to construct, it has proven to effectively prevent the deadly disease. But some have asked if the structures would hold up in extreme weather and adequately protect the trees. Hurricane Ian helped …
In the latest All In For Citrus podcast, Christopher Vincent, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor of tree ecophysiology, discussed a project he is working on in the wake of this season’s hurricanes. He has been tasked to work with growers to survey damage after the storms, specifically how winds harmed groves. Hurricane Ian …
The Citrus Research and Field Trial (CRAFT) Foundation has extended the deadline for CRAFT Cycle Four to Dec. 31 at 5 p.m. It made the extension in response to multiple requests. The foundation recognized that many Florida citrus growers have had to shift their focus and time for the past couple of months to deal with hurricane recovery. GROWER INCENTIVESCRAFT …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) recently received a large grant from the U.S. Department of Agriculture National Institute of Food and Agriculture (NIFA). Michael Rogers provides details of the $16.5 million grant during the November All In For Citrus podcast. Rogers is the director of the UF/IFAS Citrus Research and Education Center in Lake …
When Hurricane Nicole formed off Florida’s east coast, citrus growers held their collective breath after the beating they took in late September from Hurricane Ian. Nicole made landfall just south of Vero Beach on Nov. 10. Winds near hurricane strength were recorded at multiple weather stations as Nicole came ashore, including 75 miles per hour (mph) in Port St. John and …
By Megan Dewdney The story of citrus canker in Florida is unfortunately linked to hurricanes. Canker spreads far and wide with the aid of the storms. Not only can the heavy rains and high winds move the bacterium among locations, but the winds cause wounds in the canopy. Ragged leaves, scoring of leaf surfaces, thorn scratches on branches and more …
What may be the closest thing yet to a timely silver bullet for HLB was discussed Oct. 26 at Lake Alfred’s Citrus Research and Education Center. Josh Steinbronn, director of research and development at TJ BioTech, said trunk injection of his company’s ReMedium TI oxytetracycline product suppresses Candidatus Liberibacter asiaticus (CLas), the causal agent of HLB. He added that injection …
Total Florida citrus crop and tree losses from Hurricane Ian are estimated to be from $417 million to $675 million by the Florida Department of Agriculture and Consumer Services (FDACS). FDACS’ Hurricane Ian’s Preliminary Estimates of Damage to Florida Agriculture report echoed a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) preliminary assessment of $147 million to $304 …
Florida citrus likely suffered production losses ranging from $147 million to $304 million due to Hurricane Ian, according to the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). The preliminary assessment was issued Oct. 17 by the UF/IFAS Food and Resource Economics Department. “This estimate only accounts for production losses, or changes in expected revenues for the current …
