By Ariel Singerman Citrus greening (HLB) has significantly impacted the Florida citrus industry. The disease has caused tree health, yield and fruit quality to decrease significantly over time. In 2022–23, due to the combined impact of HLB, Hurricane Ian and a freeze in December 2022, the statewide average yield for both Valencia and non-Valencia oranges was estimated to be approximately …
By Christopher Vincent, Yu Wang and Nabil Killiny Mild shade reduces stress, increases growth and yield, and may improve pest management under huanglongbing (HLB). It reduces high temperature and water stresses. Shade also may reduce HLB transmission by making trees less visible to Asian citrus psyllids (ACP). Shaded trees have less ACP, and shade appears to reduce the severity of …
Federal and state agriculture officials in late September established Oriental fruit fly (OFF) quarantines in Sacramento, San Bernardino and Riverside counties in California. The actions were taken by the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (USDA APHIS) and the California Department of Food and Agriculture (CDFA) following OFF detections in those areas. The new quarantines come …
By Ute Albrecht The German scientist Paul Ehrlich pioneered the research for “magic bullets” — chemicals that could kill a microorganism but did not harm the patient. He also coined the term “chemotherapy” and paved the way for developing synthetic drugs. The first synthetic antibiotic (the first sulfa-type antibiotic) to successfully treat human bacterial diseases without major side effects was …
Due to major problems with pests and diseases, Brazilian producers have adopted alternative practices, such as dense planting, Fundecitrus’ Citricultor magazine recently reported. These practices reduce costs, increase yield and achieve a faster return on investment. As a result of this trend, new production practices are needed to improve management, including the frequent pruning of trees, which is essential in …

The initial 2023–24 California navel orange forecast is 74 million cartons. This is up 1% from the previous year, the California Department of Food and Agriculture (CDFA) reported. The forecast is based on the results of the 2023–24 navel orange objective measurement survey, which was conducted from June 19 to Sept. 1, 2023. Estimated fruit set per tree, fruit diameter, …
By Ute Albrecht and Leigh Archer Trunk injection is an alternative technique for applying crop protection materials. This technology has now been approved to deliver oxytetracycline (OTC) for huanglongbing (HLB) management in Florida. Injections cause injury, and best practices need to be established to minimize injection-induced tree damage. University of Florida Institute of Food and Agricultural Sciences researchers (UF/IFAS) injected …
On Sept. 20, Georgia Agriculture Commissioner Tyler Harper announced, in coordination with the U.S. Department of Agriculture (USDA) and the University of Georgia (UGA), the discovery and destruction of a second yellow-legged hornet’s nest on Wilmington Island near Savannah. The yellow-legged hornet is a non-native species that, if allowed to establish in the United States, could threaten honey production, native …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center breeding program has released three new scion cultivars in the last year. These cultivars provide opportunities for diverse segments of the Florida citrus industry, including nurseries catering to the home landscape marketplace. The new releases demonstrate the value of a broad-based breeding program to …
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 …
The 2023–24 California forecast for Tango and W. Murcott Afourer mandarins is 21 million 40-pound cartons, the California Department of Food and Agriculture (CDFA) recently reported. This forecast is based on the results of the 2023–24 mandarin objective measurement survey, which was conducted from July 1 to Sept. 1, 2023.

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 …
By Ozgur Batuman Plant virus diseases are unusually difficult to manage if introduced into new production sites. Citrus-infecting viruses, particularly those spread by insect vectors, are no exception to this. Florida is regularly challenged by a barrage of invasive pests and pathogen species that could devastate the citrus industry. Viruses causing citrus leprosis and citrus yellow vein clearing diseases are …
Using the plant growth regulators (PGRs) gibberellic acid (GA), 2,4-D and cytokinin in combination can maximize the benefit for HLB-affected trees, researcher Tripti Vashisth reported recently. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor of citrus horticulture and production works at the Citrus Research and Education Center in Lake Alfred. She discussed the benefits of …
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.
