Sponsored Content In this special series, Tom Johnson, owner of TJ BioTech, tackles questions about optimizing trunk-injection applications to treat HLB. Q: Some are suggesting that oxytetracycline injections may be creating tree injury due to low pH. What have you learned about this from your ongoing research? Tom Johnson: A substantial amount of research has been conducted by TJ BioTech …
Alico, Inc.’s Citrus Division harvested more fruit in the three months and nine months ended June 30 than during the same periods in the prior fiscal year. Harvests for the three-month and nine-month periods were approximately 0.8 million and 3.1 million boxes, respectively, compared to 0.4 million boxes and 2.7 million boxes, respectively, in the prior fiscal year. POUND SOLIDS AND …
Citrus Australia has assured Australian consumers they will continue to have consistent access to orange juice made from locally grown fruit. Adverse growing conditions and the spread of the huanglongbing (HLB) disease have reduced orange production in Brazil, Florida and several other key citrus-growing regions around the world. This has created a global shortage of orange juice concentrate, prompting media …
By Davie Kadyampakeni, Muhammad Shahid and Alisheikh Atta Current citrus nutrient guidelines are based on studies of healthy citrus trees conducted in the pre-huanglongbing (HLB) era. These guidelines may no longer be valid for the present situation where 100% of mature citrus trees in Florida are HLB-affected. Scientists at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) …
By Mongi Zekri Foliar fertilizer application is certainly not a new concept to the citrus industry. For over six decades, foliar fertilization has been recommended to correct zinc, manganese, boron, copper and magnesium deficiencies in citrus. It is now common knowledge in agriculture that properly nourished crops may tolerate insect pests and diseases. Traditionally, citrus growers try to achieve optimum …
South Africa’s orange and orange juice (OJ) production are projected to increase in 2023–24 compared to the prior year, the U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS) reported recently. ORANGES Orange production for 2023–24 is forecast to increase to 1.69 million metric tons (MMT), from 1.63 MMT the prior year. The South African area planted in oranges is …
The U.S. Department of Agriculture Animal and Plant Health Inspection Service (USDA/APHIS) in June established a host list of regulated articles for the Queensland fruit fly (QFF). The pest, which has been found in California, is native to Australia and is not endemic to the United States. QFF attacks more than 120 plant species, including numerous commercial varieties of fruits …
The U.S. Department of Agriculture National Agricultural Statistics Service (USDA NASS) issued its final citrus forecast for the 2023–24 season on July 10. FLORIDA The Florida all-orange forecast rose 1% from the June forecast to 17.96 million boxes. That exceeds 2022–23 production of 15.82 million boxes but is far below 2021–22 production of 41.2 million boxes. Non-Valencia orange production is …
This spring, the seventh International Research Conference on Huanglongbing (IRCHLB) was held in Riverside, California. The inaugural event was held in 2008 and funded by a grant from the U.S. Department of Agriculture (USDA) National Institute of Food and Agriculture. USDA researcher Tim Gottwald and University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) professor Jim Graham founded the …
Blood oranges teeming with antioxidants and other health benefits may be a shot in the arm for consumers and citrus growers, if the fruit is stored at cool temperatures, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) study shows. But it’s too soon to know if blood oranges are a viable crop for the Florida citrus industry, …
A wealth of observations are being recorded by growers and scientists on the effects of trunk injection of oxytetracycline (OTC). Visually, trees have responded with better canopies. Hopefully, higher yields and quality will continue to follow the applications. But what about below ground? There have been recorded improvements in citrus root mass in treated trees. Sarah Strauss, associate professor of …
By Jawwad Qureshi The Asian citrus psyllid (ACP, Figure 1) is the vector of huanglongbing (HLB) disease associated with the phloem-limited bacterium Candidatus Liberibacter asiaticus. Infected trees start to decline and produce poor-quality fruit, which drops prematurely. Consequently, citrus production has decreased dramatically since the advent of HLB in Florida in 2005. There is no cure for the disease yet. …
Few would dispute that the approval of oxytetracycline (OTC) for use as a trunk-injection therapy to treat HLB is one of the biggest breakthroughs in the nearly two decades of fighting the disease. Most Florida citrus growers believe the therapy has been a net positive and they are committed to continuing the treatment. However, there’s a stipulation in the labels …
The U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS) has reduced its 2023–24 production forecasts for Argentine oranges and tangerines by 44% and 30%, respectively, since the last forecasts. The 2023–24 crops are now expected to be 650,000 metric tons (MT) of oranges and 280,000 MT of tangerines. The decrease in production is due to a combination of factors, …
The pros of using interstocks for HLB management seemed to outweigh the cons, based on a presentation horticulturist Manjul Dutt made at this spring’s Florida Citrus Growers’ Institute. Dutt is a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor. An interstock is a graft of a citrus selection that can be used as a bridge between …
Jianhua Mo, a research entomologist with Australia’s New South Wales Department of Primary Industries (NSW DPI) authored an article about the release of parasitic wasps for the control of citrus gall wasps (CGW). Edited excerpts follow: CGW is a pest of major concern in the southern citrus-growing regions of the Riverina, Sunraysia and Riverland. With the exception of the adult …
The June 11 federal citrus crop forecast for 2023-24 shows mostly slight changes for all Florida varieties and no production changes in other states. ORANGES The Florida all-orange forecast rose less than 1% from May, or 60,000 boxes, to 17.86 million boxes. That exceeds 2022-23 production of 15.82 million boxes but is far below 2021-22 production of 41.2 million boxes. …
By Ute Albrecht, Bo Meyering, Carol Tardivo, Gabriel Pugina and Kim D. Bowman The approaching hurricane season poses the question of why strong winds cause some citrus trees to topple over while others remain firm in the ground. Grove location, grove topography and soil type are factors that influence a tree’s ability to withstand tropical-force winds. The tree’s root structure …
The conditions for the interstate movement of citrus nursery stock and packinghouse procedures for citrus fruit from sweet orange scab (SOS) quarantined areas in California were recently revised. The actions were taken by the U.S. Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS). The actions update the “APHIS-Approved Packing House Procedures for Elsinoë australis, Causal Agent of …
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 …
