The Florida Citrus Show marked another successful event in March in Fort Pierce. The show provided attendees with a fun, informative day to learn about citrus and specialty crops while engaging with exhibitors during the tailgate-style trade show. CRAFT UPDATE Citrus Research and Field Trial (CRAFT) programs have been very popular with growers and have incentivized new citrus plantings across …
By Jawwad A. Qureshi Natural enemies are the beneficial organisms that control insect and mite pests. Citrus trees produce most of their young shoots (flush) for the year in spring and will continue to produce more in summer and fall. Arthropod activity has already started in citrus groves. For example, overwintering Asian citrus psyllid (ACP) adults have started reproducing. Other …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research found that supplemental nutrition mitigates HLB symptoms and improves fruit quality and shelf-life of Sugar Belle and Tango mandarins. Faisal Shahzad, Tripti Vashisth, Mark Ritenour and Jeffrey Brecht, all with UF/IFAS, authored an article in the Journal of the American Society for Horticultural Science about the research. The article …
In the March episode of the All In For Citrus podcast, Tripti Vashisth, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center assistant director, discusses demands that the recent freeze and ongoing drought have been putting on trees. Both factors heighten the importance of irrigation and fertilization. Vashisth notes the freeze knocked a lot …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus breeders and geneticists Fred Gmitter and Jude Grosser recently received the rare Citrus Research and Education Center (CREC) Resident Professorship Award. The award has only been bestowed four other times in CREC’s 109-year history. The award recognizes careers that have brought distinction to the CREC through outstanding programs, important …
By Davie Kadyampakeni, Alisheikh Atta and Muhammad Shahid Micronutrients are those nutrients not required in large quantities but are important for improved tree performance. In the era of huanglongbing (HLB), micronutrients such as manganese (Mn), zinc (Zn), boron (B), iron (Fe) and copper (Cu) have become very critical for optimal tree management. For example, B is known to help the …
By Davie Kadyampakeni, Jonas Pereira de Souza Junior, Edilaine Istéfani Franklin Traspadini, Shankar Shrestha and Alisheikh Atta Integrated nutrient management is critical for improved and sustainable citrus production. Typical practices include split fertilization applications, the use of leguminous cover crops and the incorporation of soil amendments. This article discusses the importance of using novel blends, including macronutrients and micronutrients, as …
The Citrus Industry section of the April 2026 issue of Specialty Crop Grower highlights ongoing efforts to strengthen Florida’s citrus sector amid challenges. Articles this month showcase education, nutrient management and variety development. A recap of the Florida Citrus Show details a successful March event in Fort Pierce that combined education with a lively tailgate-style trade show. Growers Daniel Hunt, …
By Muhammad A. Shahid, KeAndre Leaks, Davie Kadyampakeni and Carlos Aucique-Perez Postfreeze citrus tree management requires patience and careful observation rather than immediate intervention. Damage to the vascular system (cambium, xylem and phloem) may take months to fully appear. Trees can initially flush in spring but later decline if internal tissues are too compromised. A reliable assessment of survival should …
The Citrus Research and Development Foundation (CRDF) board of directors held a lengthy discussion about the upcoming merger with the Citrus Research and Field Trial (CRAFT) Foundation during its March meeting. Then the board considered research projects and funded four of them. A project by Hailing Jin of the University of California Riverside will test trees in Florida which contain …
The March All In For Citrus podcast previews a couple of events coming in April and May that growers will want to mark on their calendars. Michael Rogers, director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC), discusses the Florida Citrus Growers’ Institute scheduled for April 14 at South Florida …
By Lauren Diepenbrock Citrus under protective screen (CUPS) has provided growers with a profitable method for producing fresh fruit in Florida. Growers who have implemented this system have noted quality fruit production and reduced inputs. However, when changes are imposed to the production environment, they are also imposed to the invertebrate pest complex, which can be either beneficial or detrimental …
Growers have always been innovators, testing new production practices in their groves. When you add a disease like HLB, those experiments get ramped up in the effort to seek solutions. A good example of this was a discussion that began last year among growers that ascorbic acid (vitamin C) might be helpful in extending the effectiveness of the oxytetracycline (OTC) …
Edwin A. Gutierrez-Rodriguez and Jonael Bosques, both with University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Extension, recently explained why patience is an important post-freeze tree management strategy. Following are highlights from the article they wrote. After Florida’s recent freeze event, a common question citrus growers were asking was: “What should I do to recover the trees?” The …
By Peter Chaires There are presently two groups of University of Florida (UF) citrus varieties, licensed to Florida citrus nurseries via New Varieties Development & Management Corp. (NVDMC), the licensing designee of the Florida Department of Citrus. These include: GROUP ONE Get more details on group one in the February 2025 Citrus Nursery Source article. GROUP TWO Find more information …
Florida citrus producers have long used copper as a way to protect against citrus canker. However, it’s time for growers to have other options. That’s a message shared by Ozgur Batuman, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor and citrus pathologist at the Southwest Florida Research and Education Center in Immokalee. He spoke on this …
By Tripti Vashisth, Abhishek Neupane and Taylor Livingston Florida citrus trees are under pressure from huanglongbing (HLB). The disease weakens root systems, reducing the tree’s ability to take up water and nutrients. Compounding this issue, most Florida groves sit on sandy soils with very little organic matter. These soils drain quickly, struggle to hold nutrients and allow both water and …
By Tripti Vashisth and Prudhvi Vulchi Plant growth regulators (PGRs) have become an important management tool for Florida citrus growers facing the challenges of huanglongbing (HLB). HLB disrupts the tree’s hormonal balance by reducing growth-promoting hormones like cytokinin and gibberellins and increasing stress-related hormones. This imbalance weakens carbohydrate transport, reduces sink strength and accelerates canopy decline. PGRs can help restore …
In a recent virtual presentation, entomologist Jawwad Qureshi discussed monitoring and control measures for citrus pests in trees under individual protective covers (IPCs) and in citrus under protective screen (CUPS). Qureshi is an associate professor at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education Center in Immokalee. MONITORING METHODS Qureshi’s noted that …
