News for citrus growers around the globe
The U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS) projected a slight decrease in European orange production in 2023–24 and a slight increase in orange juice (OJ) and grapefruit production. ORANGES The USDA FAS semi-annual report projects 2023–24 EU orange production at 5.475 million metric tons (MMT), down from the already short prior-year crop of 5.58 MMT. Orange production …
Fundecitrus recently announced two efforts aimed at assisting Brazilian growers with citrus greening. A São Paulo task force will include a focus on the disease, and a credit line will be available for growers with greening in their orchards. In addition to greening, the public/private task force will address development of biofertilizer and biological research, studies to increase productivity in …
Jake Price, University of Georgia (UGA) county Extension coordinator, recently wrote the following article about irrigation and fertility for Georgia citrus: I don’t think it has rained since my last blog! Make sure to check your irrigation to make sure it’s working properly. In the research plot, it is very common for the microjets to be stopped up or not spraying properly. …
Sarah Strauss, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) soil microbiologist, joined the June All In For Citrus podcast episode to discuss her research on the interaction of oxytetracycline (OTC) currently being injected into citrus trees and the soil microbiome. She noted that OTC does change the soil microbial community. The good news is that the changes …
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 …
A recent update of Millennium Block research at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center in Fort Pierce indicates the 5,500 trees in the project are yielding promising results. The four trials within the Millennium Block aim to unlock the genetic potential of new scion and rootstock hybrids never tested …
The U.S. Department of Agriculture Natural Resources Conservation Service (USDA NRCS) and The Nature Conservancy (TNC) in Florida have purchased a conservation easement at G Road Grove, a citrus grove and tree nursery in Florida panther habitat. G Road Grove expands the protected area within the Florida Panther Dispersal Zone, a 30,000-acre corridor in Hendry and Glades counties. The …
The incidence of citrus greening disease (HLB) in Brazil’s Citrus Belt of São Paulo and Triângulo/Southwest Mineiro rose from 24.42% in 2022 to 38.06% in 2023, according to Fundecitrus. The association’s annual survey indicates the disease increasingly demands more effective and collaborative measures. At a session of Brazil’s Expocitrus in June, Fundecitrus researcher Marcelo Miranda discussed the development of greening …
In the fall of 2022, five University of Florida researchers investigated Florida residents’ attitudes on HLB and Asian citrus psyllids (ACP) using online surveys over a 9-month period. The results of the study, Residents’ contribution to Asian citrus psyllid and citrus greening management in Florida residential habitats, was recently published in the Journal of Integrated Pest Management. Authors Romain Exilien, …
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, …
Tanishka Balaji Aglave of Valrico, Florida, received the $10,000 H. Robert Horvitz Prize for Fundamental Research for her investigation into a natural alternative treatment against citrus greening disease (known as huanglongbing, or HLB). Aglave, a 15-year-old who attends Strawberry Crest High School and grew up on a citrus farm, injected the trunks of infected citrus trees with an extract from …
The U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS) recently increased its 2023–24 production forecasts for Turkish tangerines, lemons and grapefruit. TANGERINES Overall tangerine production is forecast to increase 55% to 2.88 million metric tons (MMT) due to favorable spring rains and temperature conditions during blossoming in March 2023. Tangerines are the most produced citrus fruit in Türkiye, with …
A study by researchers from the Guangdong Academy of Agricultural Sciences and South China Agricultural University sheds light on the genetic mechanisms that can defend against Asian citrus psyllid (ACP) infestation. ACP is the vector for HLB, the most devastating disease of citrus. The study was published in Horticulture Research on April 1. It unveils the roles of two cytochrome …
A coalition of states, including Florida and Georgia, recently joined a lawsuit filed by the Southeastern Legal Foundation (SLF) challenging the U.S. Department of Labor (DOL) Farmworker Protection Rule. DOL announced the final rule in late April, saying it would strengthen protections for farmworkers in the H-2A program. The Farmworker Protection Rule will become effective June 28, 2024. SLF is …
The conversation in Florida citrus continues to center around trunk injection of oxytetracycline (OTC). The July issue of Citrus Industry magazine presents the latest information on the OTC topic. OTC product labels require a one-year pause in application after two years of use. This requirement was put in place to prevent pathogen resistance to the product. Florida growers who have …
The U.S. Department of Agriculture Agricultural Research Service (USDA-ARS) citrus scion breeding program recently rediscovered several noteworthy grapefruit cultivars at the A.H.
