Better Blood Oranges a Possibility for Florida Growers
Blood oranges teeming with antioxidants and other health benefits may be a shot in the arm for consumers and citrus growers, if the fruit is stored at cool temperatures, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) study shows. But it’s too soon to know if blood oranges are a viable crop for the Florida citrus industry, …
Reduce Fruit Drop From Phytophthora-Induced Brown Rot
By Chris Oswalt During this time of the year, Florida growers should be aware of the potential for the development of citrus brown rot disease. It can infect fruit at color break. If severe, the disease can cause a significant amount of infected fruit to drop. For this reason, groves with a history of brown rot in areas that recently …
KeyPlex Citrus Symposium to Address Fruit Drop
KeyPlex has scheduled a citrus symposium for July 25 at the SEVEN Sebring Raceway Hotel.

Study Looks at Interaction Between OTC and Soil Microbiome
A wealth of observations are being recorded by growers and scientists on the effects of trunk injection of oxytetracycline (OTC). Visually, trees have responded with better canopies. Hopefully, higher yields and quality will continue to follow the applications. But what about below ground? There have been recorded improvements in citrus root mass in treated trees. Sarah Strauss, associate professor of …
Florida Labor Contractor Cited in Orange Harvester Death
A federal workplace safety investigation found a Florida labor contractor could have prevented the fatal illness of a 41-year-old worker who collapsed while harvesting oranges at Alico Farms in December 2023. According to investigators, the incident could have been avoided if the required steps to protect employees from hazards associated with high temperatures were taken. Inspectors with the U.S. Department of Labor’s …
Export Expectations Changed for Moroccan Citrus
Export expectations are the only major changes made in a recent U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS) semi-annual citrus report for Morocco. Production forecasts remain the same as in the agency’s December 2023 annual citrus report.Here’s a look at the export changes: TANGERINES/MANDARINS Tangerine/mandarin export expectations for 2023–24 were revised down to 400,000 metric tons (MT) from …
Heat-Related Illness Toolkit Available
The Southeastern Coastal Center for Agricultural Health and Safety (SCCAHS) and the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) have created an online toolkit to help protect agricultural workers from the summer heat. Last year’s sweltering summer temperatures convinced SCCAHS leadership that additional promotion about heat-related illness education could save lives. Even before the summer ended, the …
Slight Changes in European Citrus Production
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 …
Task Force and Credit Line to Assist Brazil with Greening
Fundecitrus recently announced two efforts aimed at assisting Brazilian growers with citrus greening.

ACP Management in High-Density Plantings
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. …
Seeking a Partner for OTC
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 …
