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. …
The only change in the Feb. 8 citrus crop forecast from the U.S. Department of Agriculture’s National Agricultural Statistics Service (USDA NASS) was a 700,000-box reduction in Florida non-Valencia oranges compared to the January forecast. That reduced the expected 2023–24 Florida non-Valencia crop to 6.8 million boxes and the total Florida orange crop to 19.8 million boxes. The percentage reductions …
By Frank Giles The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has established itself as a leader in new technological frontiers like artificial intelligence (AI). In fact, the school has the 15th most powerful computer in the world. The HiPerGator, as the computer is called, will assist in AI development and on many other technological fronts. Another …
The effort to help huanglongbing (HLB)-impacted citrus trees has taken another step forward. A University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) study examined the relationship between fertilization, root health and fruit yield. Researchers focused on Valencia orange trees with HLB. Associate Professor Davie Kadyampakeni led the effort at the UF/IFAS Citrus Research and Education Center. The study, …
The quest for long-term solutions to HLB is well underway. Technology like CRISPR is being developed to introduce tolerance or resistance to HLB. Conventional breeding also is seeking rootstocks and varieties that can resist the disease. In the meantime, growers are reminded to utilize available tools that help trees remain productive in an HLB environment. During the August Citrus & …
Australian orange juice (OJ) production in 2023–24 is forecast at 15,400 metric tons (MT) by the U.S. Department of Agriculture’s Foreign Agricultural Service (USDA FAS). That’s a decrease of 4% from the 2022–23 estimate of 16,100 MT. Higher production and improved fruit quality for fresh oranges is anticipated in 2023–24, resulting in a lower volume of rejected fruit channeled toward …
In the Jan. 12 citrus forecast from the U.S. Department of Agriculture’s National Agricultural Statistics Service (USDA NASS), Florida’s citrus crop estimates were unchanged from December, but other citrus-producing states saw changes. CALIFORNIA UPS AND DOWNSThe California forecast for oranges increased for both Valencias and non-Valencias. The Valencia crop rose from 7.5 million boxes to 7.8 million boxes. Non-Valencias increased …
By Randall P. Niedz, Guilherme Locatelli, Nick Larson, Lorenzo Rossi, Ellen Cochrane and Michelle Heck Scientists at the U.S. Department of Agriculture-Agricultural Research Service (USDA-ARS) developed an idea to bypass lab assays and test molecules directly in the field for their ability to solve HLB. As part of a USDA National Institute of Food and Agriculture (NIFA) grant (number 2020-70029-33176), …
By Davie Kadyampakeni Huanglongbing (HLB) is a citrus disease that affects the growth of the fibrous roots of citrus trees. This means that HLB-affected trees may have reduced root volume, which impacts water uptake. A greenhouse study was conducted from October 2019 to July 2021 at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and …
John Chater has been on the job now for two years, working with growers to evaluate variety performance in field trials. In the latest All In For Citrus podcast episode, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor discusses his work, including grower collaboration to study new varieties in real-world environments. Chater also talks about …
Egyptian orange production in 2023–24 is projected to increase 2.7% from the prior season to 3.7 million metric tons (MMT), the U.S. Department of Agriculture’s Foreign Agricultural Service (USDA FAS) reported. The increase in production is attributed to optimal weather conditions and temperatures during flowering of the trees, which increased fruit set and production. Oranges are the major citrus crop …
By Jawwad A. Qureshi, Lauren Diepenbrock and Davie Kadyampakeni Protecting citrus trees from the Asian citrus psyllid (ACP) is critical to reducing the spread and severity of huanglongbing (HLB) disease. The frequent availability of viable shoots in young trees is attractive to psyllid colonization, feeding and oviposition events. UV-metalized reflective mulches reflect ultraviolet light, which is disturbing for some insects …
By Tom Spreen The Florida citrus industry has experienced a difficult stretch of years since the record crop year of 2003–04, when over 240 million 90-pound boxes of oranges were produced. INDUSTRY DECLINEIn 2004, multiple hurricanes crisscrossed the Florida peninsula. They were the first hurricanes to hit the citrus-producing area of Florida since Hurricane Dora in 1964. The hurricanes themselves …
As recently as five years ago, Florida citrus growers did not routinely put individual protective covers (IPCs) on their trees as part of their grove management. Now, the mesh IPCs cover at least 1 million trees on about 17,000 acres, mostly thanks to experimentation by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher Fernando Alferez. IPCs keep …
The updated forecast for the 2023–24 orange crop in Brazil’s citrus belt is 307.22 million boxes of 40.8 kilograms each. That’s a reduction of 2.12 million boxes, or 0.7%, from the September forecast of 309.34 million boxes. The update was issued Dec. 11 by Fundecitrus in cooperation with its partners. The forecast, by varieties, is: IMPACTS ON FRUIT SIZE In …
In the Dec. 8 citrus forecast from the U.S. Department of Agriculture’s National Agricultural Statistics Service (USDA NASS), Florida’s grapefruit and tangerine/tangelo production estimates increased. The all-grapefruit forecast for Florida leaped 26% compared to the season’s initial forecast in October. The state’s tangerine and tangelo forecast climbed 10%. All other variety forecasts in the citrus-producing states — Arizona, California, Florida …
Alico Citrus, a division of Alico, Inc., harvested less than half its citrus in the fiscal year ending Sept. 30, 2023 as it did in the prior year. The decline was largely the result of impacts from Hurricane Ian in September 2022. Alico has approximately 49,000 citrus acres in seven Florida counties. The company reported on Dec. 6 that it …
The fresh-market orange crop in the United States rose 2% in 2022–23 compared to the prior year, to 1.44 million tons, the U.S. Department of Agriculture’s Economic Research Service reported this fall. The increase was due to larger navel orange and early/midseason crops in California and Texas. FRESH FRUIT PRICES FALL With increased supply, grower prices for fresh oranges were …
By Davie Kadyampakeni, Lorenzo Rossi and Alan Wright Huanglongbing (HLB) disease lowers tree performance by reducing water and nutrient uptake as a result of root loss. HLB-affected trees have a fibrous root loss of about 30% to 80%, which increases as disease symptoms develop in the canopy. Investigating optimal nutrient concentrations in citrus roots thus improves the understanding of HLB …
The U.S. Department of Agriculture National Agricultural Statistics Service’s (USDA/NASS) final estimates for the 2022–23 season show U.S. citrus production reaching 4.9 million tons, down 12% from 2021–22. This marks the lowest combined production levels for U.S. citrus in at least 50 years. The U.S. citrus crop was valued at $2.6 billion in 2022–23, 13.5% below the prior year’s value. …
