With an investment of $200 million (in Brazilian reals), three citrus research organizations in Brazil have partnered to create a research center in São Paulo to seek solutions to citrus greening. The São Paulo Research Foundation (FAPESP), Fundecitrus and Luiz de Queiroz College of Agriculture at University of São Paulo (ESALQ-USP) agreed on Jan. 12 to establish the Applied Research Center …
Fundecitrus doctoral student Lisseth Bibiana Puentes Figueroa received the Best Paper award in the Agricultural Microbiology category at the XV Brazilian Symposium on Applied Microbiology/VII Latin American Meeting on Applied Microbiology. Figueroa is affiliated with the Graduate Program in Agricultural Microbiology at the Luiz de Queiroz College of Agriculture/University of São Paulo (ESALQ/USP) and is supervised by Fundecitrus researcher Franklin …
The U.S. Department of Agriculture (USDA) recently issued a directive about its research and development priorities. The priorities, which cite citrus greening in item 3, are: 1. INCREASING PROFITABILITY OF FARMERS AND RANCHERS While research to increase productivity has allowed American farmers and ranchers to provide the safest, most abundant and most affordable food and fiber supply, the volatility in …
Fundecitrus recently held an international seminar dedicated to citrus greening. The event had approximately 150 participants and featured experts from China and Brazil. GENOME EDITING Xuefeng Wang, from China’s Southwest University’s Citrus Research Institute, highlighted his interest in building a solid partnership in the area of genome editing. He said his group has already identified promising genes that can contribute …
Fundecitrus’ annual survey of citrus greening incidence shows that in 2025 the disease affected 47.63% of orange trees in the Citrus Belt of São Paulo and the Triângulo/Southwest Minas Gerais region. This represents a 7.4% increase compared to 2024, when the incidence was 44.35%. SLOWER RATE OF INCREASE However, for the second consecutive year, a slowdown in the rate of …
Federal and state agriculture officials have expanded the quarantine for citrus greening in the Perris area of Riverside County in California by 33 square miles. The U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS) in cooperation with the California Department of Food and Agriculture (CDFA) expanded the quarantine. The measure parallels the intrastate quarantine that CDFA established …
According to Fundecitrus, the arrival of budding in orange groves marks a critical period for Brazilian citrus growers. The budding process intensifies with the onset of rain, requiring more rigorous control of the psyllid that feeds on buds and transmits the bacteria that causes citrus greening. The budding period, which runs from July to October in Brazil, accounts for between …
Citrus greening disease has yet to find its footing in Georgia. But that doesn’t mean it can’t or won’t eventually. Mary Sutton, University of Georgia assistant professor and citrus Extension specialist, discussed the ramifications of citrus greening during the recent Southeast Citrus Update in Lyons, Georgia. “If we get greening established here, we’ll start seeing lower and lower production on …
Fundecitrus Executive Director Juliano Ayres and researcher Nelson Wulff visited China recently to learn about strategies to combat citrus greening and to strengthen research partnerships. Their agenda included technical visits and participation in an international symposium on biotechnological innovations aimed at controlling greening. Among the highlights was a visit to the greenhouse of the Chinese Academy of Sciences in Beijing. …
Federal and state agriculture officials recently expanded the areas quarantined for citrus greening disease in California. They expanded the quarantined area in the Coto de Caza area of Orange County by 11 square miles, the Rancho Santa Margarita area of Orange County by 93 square miles, the Perris area of Riverside County by 37 square miles, and the Rancho Cucamonga …
The recent U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS) annual report on Brazilian citrus included updates on citrus greening disease, production and planted area. CITRUS GREENING The report noted that new chemicals and practices have been developed to fight citrus greening, a major cause of recent production declines. Those chemicals and practices include a natural repellent called caryophyllene, …
Pruning is an efficient strategy to improve citrus greening disease management in Brazil’s Citrus Belt, but requires appropriate procedures and attention from the grower, Embrapa and Fundecitrus researchers reported recently. Embrapa researcher Eduardo Girardi said an orange tree could produce normally without the need for pruning “if the orange tree has no restrictions on its growth.” Without growth restrictions, Girardi …
Agriculture officials have expanded the areas quarantined for citrus greening (huanglongbing; HLB), caused by Candidatus Liberibacter asiaticus, in Texas. All of Zapata County has been added to the quarantined areas. The action was taken by the U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS) in cooperation with the Texas Department of Agriculture (TDA). The action was taken …
Lukas Hallman is about to embark on an internship in Switzerland to investigate the vascular system of trees affected by citrus greening. Hallman is in his final year of a Ph.D. program in horticultural sciences at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center. He is under the guidance of Lorenzo …
Fundecitrus says it repudiates recent articles that claim productivity in Brazil’s São Paulo and Minas Gerais citrus belt will be reduced by 60% in the next five years due to citrus greening disease. Fundecitrus says Chilean and Spanish news portals published such reports on Nov. 14. According to Fundecitrus, this information is not valid, nor was it ever provided by …
Citrus greening disease is no longer just a problem in residential trees in Georgia. For the first time last year, citrus greening, also known as huanglongbing or HLB, was observed in commercial plantings in Pierce, Wayne and Grady counties, says Jonathan Oliver, University of Georgia (UGA) assistant professor and small fruits pathologist. Oliver discussed the disease during a citrus meeting …
“Life as a citrus grower is a perilous journey,” says Chip Henry. Among the toughest perils the third-generation Florida grower has endured are the freezes of the 1980s, the threat of losing his land to highway construction, and the scourge of citrus greening. Henry’s story begins with the founding of O.E. McGuire Groves in Apopka by his maternal grandparents in …
It’s not a question of if citrus greening disease will be an issue for North Florida and South Georgia citrus growers, but when will it be. Fred Gmitter, a University of Florida Institute of Food and Agricultural Sciences citrus breeder, believes the disease’s impact in both areas is inevitable. He shared his assessment during a recent Cold Tolerant Citrus Production …
The University of Georgia (UGA) Plant Molecular Diagnostic Lab is a key resource for Georgia citrus growers hoping to stay sustainable. While it is a fee-based service lab for the UGA Department of Plant Pathology, it provides free testing for citrus producers concerned about citrus greening, says Jonathan Oliver, UGA assistant professor and small fruits pathologist. “The diagnostic lab here …
Jonathan Oliver, University of Georgia assistant professor and small fruits pathologist, is concerned about the potential impact of citrus greening disease in Georgia. That’s why he is encouraging Georgia growers to quickly dispose of infected trees if any are found. “Once greening becomes really widespread and established in a lot of our trees, it’s really hard to stop it,” Oliver …
