Fundecitrus has launched Evaluate Psyllid, a tool that will help citrus growers choose insecticides to manage the pest that spreads citrus greening disease. Evaluate Psyllid will make available the results of insecticide efficacy experiments on field psyllid populations in different regions of Brazil’s citrus belt. The insecticide efficacy data will be constantly updated as experiments are carried out. It will …
Bill Lennon is working with researchers to learn more about survivor trees that are standing up to HLB. Bill Lennon is a fifth-generation citrus grower who can recall the industry’s glory days when Central Florida had hundreds of thousands of citrus acres before the 1980s freezes pushed production southward in the state. But he’s remained dedicated to the area, managing …

They are also expanding three existing quarantine areas for citrus canker in Brazoria, Fort Bend, Galveston and Harris counties. The U.S. Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS) and the Texas Department of Agriculture …
The citrus industry has found footing in Georgia and needs continued support as this promising industry marches toward the future. Events like the Georgia Citrus Association annual meeting on Feb. 27 at the University of Georgia Tifton Campus Conference Center provided information tailored to protecting growers’ investments. “One of the things we wanted to do differently this year is remind …
The Texas citrus industry has faced numerous challenges in recent years, including Hurricane Hanna in 2020, winter storm Uri in early 2021 and droughts in both 2022 and 2023. After Uri, Texas grapefruit production was at about 1.6 million boxes for the 2021–22 season, down 33% from the previous year. Orange production was about 400,000 boxes, down 62%. Juan Anciso, Texas …
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 …
Production in the cold-hardy citrus region is still in its infancy. Growers and industry leaders need events like the Citrus Health Forum to obtain the necessary information to help this young industry continue to flourish. The latest forum took place at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) North Florida Research and Education Center in Quincy …
You’ve probably heard the term CRISPR in recent years. It is a relatively new breakthrough in science that has applications in human health and even in the fight against HLB. Nian Wang, a professor of microbiology and cell science with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), has been on the forefront of CRISPR research. Here …
Jake Price, University of Georgia county Extension coordinator, recently reported on the factors that influence cold hardiness of citrus. Excerpts follow: VARIETY The most obvious factor is the variety of citrus. In order of cold hardiness, the three main classes of citrus are mandarins, sweet oranges and grapefruit. Acid types of citrus such as lemons and limes are the least …
Global lemon/lime production in 2023–24 is forecast up 225,000 tons from the prior year to 10 million tons, the U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS) reported. Higher production in the European Union, South Africa and Turkey more than offsets lower production in Mexico and the United States. Here are the regional lemon/lime forecasts for 2023–24: Turkey production …
Studies with psyllid pheromones show that the insect’s behavior is altered when it is infected by the HLB-causing bacterium Candidatus Liberibacter (CLas). This makes it difficult to produce a commercial psyllid-control product based on the insect pheromone, Brazil’s Fundecitrus has concluded. “The sexual pheromone is an attractant produced by the female of the species, which promotes behavioral changes in male …
The U.S. Department of Agriculture (USDA) is allocating more than $5 million to Florida for plant-health protection. The funding is part of a nationwide effort to strengthen the country’s infrastructure for pest detection, surveillance and mitigation, as well as protect the U.S. nursery system. Through the authority of the Plant Protection Act (PPA) Section 7721, USDA is providing more than …

The California Farm Bureau and its partners have received $5 million from the California Department of Food and Agriculture (CDFA) to implement climate-smart farming practices in citrus groves in 11 counties. The project, part of CDFA’s Healthy Soils Block Grant Pilot Program, will focus on hedgerow planting, carbon sequestration and soil management practices. All of those practices create a safe …
By Frank Giles and Maegan Beatty As growers deployed their first application of oxytetracycline (OTC) via trunk-injection this summer, expectations were high but tempered by the fact the therapy is not expected to turn the massive HLB ship around in just one season. By this fall, after the seasonal cooldown, growers were still reporting generally positive signs from the treatments. …
By Tripti Vashisth Canopy health of HLB-affected citrus has been directly related to disease severity, fruit drop and overall fruit production. Some success has been found with the use of certain plant growth regulators (PGRs) such as gibberellic acid (GA) and 2,4-dichlorophenoxyacetic acid (2,4-D) to achieve healthier trees with reduced fruit drop and increased production. HLB MANAGEMENT Application of these …
By Frank Giles The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has established itself as a leader in new technological frontiers like artificial intelligence (AI). In fact, the school has the 15th most powerful computer in the world. The HiPerGator, as the computer is called, will assist in AI development and on many other technological fronts. Another …
California’s Citrus Research and Field Trials (CA-CRaFT) program is now accepting Cycle 2 applications from commercial growers. This initiative aims to showcase the efficacy of additional control measures against the Asian citrus psyllid (ACP). ACP is the carrier of the Candidatus Liberibacter asiaticus bacterium causing huanglongbing (HLB) disease in citrus. For Cycle 2, applications will be accepted until program capacity …
According to the U.S. Department of Agriculture’s Foreign Agricultural Service (USDA FAS), Brazilian orange and orange juice production are both forecast to decline in 2023–24 compared to the prior year.
