An artificial intelligence (AI) model developed by researchers in China has shown promise for detecting HLB in leaves before visible symptoms appear. The technology could eventually give citrus growers another tool for earlier disease detection and more targeted grove monitoring. The study combined three types of information: standard color photographs, hyperspectral imaging and measurements of leaf chlorophyll content. The researchers …
Even with AI-enabled and autonomous machines, orchard work still requires human knowledge, researchers at the University of California, Davis (UC Davis) determined. Their conclusion was based on a study of 16 fruit tree operations in California and Washington over three years. What changes is how the work gets done. The study, drawing on 165 in-depth interviews with workers and growers, …
The U.S. Department of Agriculture (USDA) announced Oct. 19 that it will make one-time payments to farmers this harvest season to provide relief during temporary market disruptions and increased input costs. The $8 billion available for payments provided through the Harvest Fuel Relief program is authorized under the Commodity Credit Corporation Charter Act and will be administered by USDA’s Farm …
Producers of fresh Florida citrus south and east of the Suwanee River have until Nov. 9 to vote on the continuation of Federal Marketing Order 905, Citrus Administrative Committee (CAC) Manager Peter Chaires reported. “This is an important vote and one that we hope you will take very seriously,” Chaires said. The U.S. Department of Agriculture (USDA) would consider termination …
Researchers have identified a naturally occurring citrus root bacterium that produces a compound capable of suppressing the bacterium associated with huanglongbing (HLB) disease. This offers a potential new avenue for disease management. A research study examined whether bacteria living naturally on and within citrus plants could help fight Candidatus Liberibacter asiaticus (CLas), the bacterium associated with HLB. Using an automated …
Citrus under protective screen (CUPS) provides citrus growers with a way to overcome the challenges of huanglongbing (HLB) disease. While grapefruit is the predominant variety grown in CUPS, research is underway to expand the varieties grown under screen. That’s one of the remaining CUPS research hurdles for Arnold Schumann, professor of soil fertility and water quality at the University of …
By John M. Chater Huanglongbing (HLB) has changed the citrus landscape in Florida in many ways. One important consideration is rootstock selection. HLB affects the growth rate of a citrus tree substantially. Trees grow at a much slower rate on average compared to healthy trees. In the citrus under protected screen (CUPS) environment, trees can grow faster than a healthy …
Huanglongbing (HLB), shifting consumer preferences and rising production costs are reshaping the citrus juice industry. These challenges are making fruit quality and efficient use of available crops increasingly important, a new research review reports. The researchers identify HLB as a major challenge for juice production. The disease reduces tree health, increases fruit drop and lowers yields. It can also change …
University of Georgia Professor Liang Dong is developing sensor technologies designed to detect drought, disease and insect pressure before signs of plant stress are visible. The goal is to help farmers make faster, more informed management decisions. Dong is the Georgia Research Alliance (GRA) eminent scholar in precision agriculture and also serves as associate director for research at the Institute …
Controlled-release fertilizers (CRFs) may help improve leaf nutrition in citrus trees affected by huanglongbing (HLB), but choosing the right fertilizer program is critical to maintaining yields, according to new research. A University of Florida Institute of Food and Agricultural Sciences study compared two CRF programs with a conventional fertilizer program in mature Valencia sweet orange trees growing in Florida’s sandy …
Researchers have identified two emerging bacterial species on Rangpur limes in Brazil, highlighting the importance of food-safety practices when citrus is grown near livestock or poultry operations. The researchers investigated three bacterial strains recovered during screening of lactic acid bacteria from Rangpur limes. One strain was identified as Escherichia albertii and two as Kosakonia cowanii. The researchers used biochemical testing, …
Sponsored Content The world today is experiencing significant geopolitical turmoil. For the Florida citrus industry, one important question is how to turn this uncertainty into an opportunity. While the United States is certainly not immune to global challenges, our country remains in a relatively strong position compared to many others. The United States has become the world’s largest producer of …
The U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS) announced on Oct. 7 the establishment of a West Indian fruit fly quarantine in Port Isabel, Cameron County, Texas. APHIS took the action in cooperation with the Texas Department of Agriculture (TDA). The action parallels the quarantine established by TDA on Aug. 21. APHIS is taking this action …
A new study suggests that tackling both the bacterium responsible for huanglongbing (HLB) and the tree’s own response to infection may offer a better path for managing the disease. A report on the research — “Combating citrus greening disease by simultaneously targeting the pathogen and callose-mediated phloem occlusion” — examines how the disease disrupts the movement of sugars through citrus …
By Lauren Diepenbrock Fall in Florida is not generally a time for insect, mite and other invertebrate pest populations to decline rapidly. In Florida citrus, we often see the opposite of this. MITES In the hot, dry end of summer and early fall, mite populations often soar, requiring management to prevent excessive damage to fruits. See The Florida Citrus Production …
Citrus growers and researchers know that oxytetracycline (OTC) trunk injection can reduce the amount of the bacterium associated with huanglongbing (HLB) disease and improve fruit production and juice quality. However, new research shows the treatment also causes changes in microbial functions around citrus roots. Researchers conducted a field study in a commercial Southwest Florida orchard containing 8-year-old Valencia sweet orange …
In 2025, high school student Tanishka Aglave regaled the Highlands County Citrus Growers Association (HCCGA) annual meeting with a discussion of her prize-winning investigation into a natural alternative treatment for HLB. Instead of using the standard HLB treatment oxytetracycline (OTC) as a trunk injection, she injected HLB-infected trees with an extract from the Indian curry leaf plant. She reported that …
University of California, Riverside (UCR) citrus researcher Mikeal Roose is among 23 honorees across the University of California (UC) campuses who recently received UC Regents Innovation Awards. Roose is credited with co-developing the seedless Tango mandarin. The awards recognize UC faculty members whose research has real-world impact. Roose was among 11 honored in the Distinguished Lifetime Achievement Award category for …
Blood oranges are an enticing option to help cold-hardy citrus producers diversify their crop portfolio. Muhammad Shahid, assistant professor of horticulture at the University of Florida Institute of Food and Agricultural Sciences, is researching the crop at the North Florida Research and Education Center in Quincy. Nothing has deterred him from recommending it to growers in North Florida, South Georgia …
Florida Department of Citrus (FDOC) staff and members of the FDOC’s marketing agency recently presented plans for the November 2026 to February 2027 gift fruit shipping season. Their plan is called the Florida Citrus Gifting Campaign. The marketing plan was presented during a virtual meeting of the Florida Citrus Commission’s (FCC) Florida Gift Fruit Shippers Advisory Council. The 2026–27 gift …
