The California Department of Food and Agriculture (CDFA) has declared a quarantine in Ventura County following the detection of the citrus disease huanglongbing (HLB), or citrus greening, in two citrus trees on one residential property in the city of Santa Paula. These detections are the first HLB-positive trees in Ventura County. CDFA is working with the U.S. Department of Agriculture …
Egyptian citrus could be on the way to the U.S. market after a request was made to the U.S. Department of Agriculture (USDA). A pest risk assessment has been drafted by USDA’s Animal and Plant Health Inspection Service (APHIS). Jim Cranney, president of the California Citrus Quality Council (CCQC), said the assessment is for fresh oranges and tangerines, which would …
In the nearly two decades that huanglongbing (HLB) has plagued Florida citrus groves, about $1 billion has been spent in the search for solutions. A lot of great scientists in Florida and around the world have worked on the problem, and a silver bullet, if there is one to be found, has been elusive. Researchers, along with growers, have developed …
Trunk injection of oxytetracycline (OTC) is giving growers hope for the future of the Florida citrus industry. Many are optimistic the new therapy will help improve both fruit quality and quantity. The key will be whether fruit holds on the trees until harvest time. The October issue of Citrus Industry magazine provides the latest information on OTC trunk injection from …
One of the overlooked casualties of tropical storms and hurricanes is field research conducted by scientists at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Research on new varieties, plant treatments and other practices can be upended in a day by a violent storm. That happened to some of Christopher Vincent’s research. The UF/IFAS assistant professor of …
By Frank Giles and Tacy Callies The Citrus & Specialty Crop Expo hosted two citrus educational sessions during the Aug. 16–17 event held at the Florida State Fairgrounds in Tampa. The sessions included both long-term research aimed at delivering trees resistant to HLB as well as what growers can do today to help mitigate the effects of the disease in …
By Peter Chaires Each year, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus breeding teams provide opportunities for interested parties to sample fruit from new and recent selections. This is a great opportunity to remain current on research results. Participation from growers, processors, packers, marketers and fruit enthusiasts is desired. Shoppers in produce departments represent a …
Citrus researcher Nian Wang has been appointed to the Graves Eminent Scholar Chair in Biotechnology at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Wang is a professor of microbiology and cell science at the Citrus Research and Education Center (CREC). He was appointed to the chair because of his work to develop a tree resistant to …
By Tacy Callies Before they were married, Nate and Anna Jameson vowed they would one day farm for themselves. They met while attending the University of Florida. Nate graduated with a Bachelor of Science in ag operations management, while Anna earned her degree in animal science. After graduation, Anna worked for Lykes Meat Group and Nate for Ben Hill Griffin …
The first update of the 2023–24 orange crop forecast for the São Paulo and West-Southwest Minas Gerais citrus belt confirmed the initial May forecast of 309.34 million boxes. Fundecitrus announced the update on Sept. 11. The forecast for Hamlin, Westin and Rubi varieties was increased 3.5% to 58.09 million boxes. Other early-season varieties climbed 1.6% to 18.51 million boxes. The …
In August, Horticulture Research published a paper titled An endolysin gene from Candidatus Liberibacter asiaticus confers dual resistance to huanglongbing and citrus canker. Researchers found that an endolysin encoded by the Candidatus Liberibacter asiaticus (CLas) prophage has dual resistance to huanglongbing (HLB) and citrus canker. A prophage is the genetic material of a bacteriophage, and a bacteriophage is a virus …
Argentine fresh orange and tangerine production will decline in 2022–23 compared to the prior season, the U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS) forecast recently. Fresh orange production is forecast at 623,000 metric tons (MT), down from 830,000 MT the prior season. Fresh tangerine production is projected to decrease to 285,000 MT, down from 380,000 MT the prior …
Brazil’s São Paulo and Minas Gerais citrus belt has gone through four low orange production cycles in a row, the Brazilian Association of Citrus Exporters (CitrusBR) pointed out in a recent report on orange juice processing. The association noted that orange production in Brazil’s citrus belt totaled 269 million boxes in the 2020–21 season, 263 million boxes in 2021–22, 314 …
The secretary of agriculture and supply of the state of São Paulo, Brazil, in partnership with Fundecitrus, has launched a campaign to replace plants that are hosts for the HLB-spreading psyllid. HLB disease is also known as citrus greening. The campaign, called Plant This Idea, aims to replace citrus and myrtle plants with fruitful and ornamental plants in rural backyards …
The U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS) recently estimated that world citrus production is down for oranges, mandarins, orange juice (OJ), grapefruit and lemons/limes. For all categories, production will be lower in 2022–23 than in the prior year. OJGlobal OJ production for 2022–23 is estimated 9% lower to 1.5 million metric tons (MMT). Production is down due …
U.S. Department of Agriculture Agricultural Research Service (USDA ARS) scientists have discovered a way to augment a citrus tree’s natural resistance to pathogens, including HLB. The scientists are in the Crop Improvement and Genetics Research (CIGR) unit in Albany, California. According to James Thomson, a geneticist at CIGR, by incorporating receptors that can recognize pathogens, scientists are able to activate …
Citrus Australia has urged the federal government to repeal its proposed Biosecurity Protection Levy. Announced under the government’s 2023–24 budget, the levy will apply to Australian producers of agricultural, forestry and fishery products starting July 1, 2024. The levy has been set at a rate equivalent to 10% of the 2020–21 industry-led agricultural levies. This is estimated to increase receipts …
Global orange production for 2022-23 is estimated by the U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS) at 47.8 million metric tons (MMT), 5% less than the prior year. Lower production in the European Union, Turkey and the United States is only partially offset by a larger crop in Egypt. U.S. production is estimated to drop by over a …
By Megan Dewdney To make informed management decisions, growers need to know about and understand the findings from huanglongbing (HLB) research that are currently available. However, the delivery of research results to growers is often fragmented, and results can be difficult to find. Furthermore, what information and conclusions are available to growers from projects or scientific journals can be highly …
By Jawwad 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) or citrus greening disease. ACP, the vector of the pathogen responsible for causing HLB in citrus, needs young shoots to develop and reproduce. The frequent availability of viable shoots in young trees …
