By J. Scott Angle, jangle@ufl.edu, @IFAS_VP The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) is committed to updating nutrient management recommendations for citrus. For the next two months, that means seeking state funding for the research. The UF/IFAS team was crafting a specific proposal to the Legislature as of this writing. It’s at the very top of …
By Megan Dewdney Last summer, I received many calls about algal spot, especially in late June to early July. Algal spot is a disease, caused by the algae Cephaleuros virescens, that occurs mostly on citrus tree limbs. Much of the year it is difficult to see because it is a gray-green color that blends into the color of citrus bark. …
By Lukasz L. Stelinskiand Jawwad A. Qureshi Asian citrus psyllids (ACP) are at the mercy of their host (citrus) for survival. They need flush to lay eggs and for the nymphs to develop. Prior to HLB, the majority of flushing had been fairly predictable and occurred in the early spring and late summer. The occurrence of flush in young trees …
In a Jan. 12 virtual Zoom seminar from Immokalee (dubbed “Zoom’okalee” in the presentation), researcher Ozgur Batuman reviewed old and new approaches to controlling HLB. The seminar was titled “Citrus Disease Trends We Should Heed: HLB, Phytophthora and Leprosis.” Batuman works for the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education Center (SWFREC) …
By Lauren Diepenbrock Managing lebbeck mealybug has become an ongoing challenge in many citrus-growing areas of Florida. This pest expanded into 14 counties from 2019 to fall of 2021 and impacts both commercial and residential citrus. Damage includes distorted fruit and leaves, stem dieback and fruit drop. Loss of young trees can occur under extreme infestation scenarios. In addition to …
As they battle HLB, growers must control costs wherever possible, including by applying pesticides and fertilizer more efficiently. With that in mind, Yiannis Ampatzidis is engaging artificial intelligence (AI) to develop a low-cost, smart tree-crop sprayer that can automatically detect citrus trees, calculate their height and leaf density, and count fruit. That way, growers target their spray more efficiently, so …
By Michael Rogers January marks the season for resolutions: exercising more, eating well and being more organized. But in the research world, resolutions may not be that simple. I don’t think that University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers could be any more “resolved” in finding ways to fight citrus diseases and ways to improve how …
By Tripti Vashisth In a multi-year field trial, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers have seen beneficial effects of gibberellic acid (GA) on Valencia sweet oranges. Monthly application of GA (September to January) on Valencia improved yield on average by 30%, reduced fruit drop and elicited enhanced plant defense response. These benefits are possibly due …
Researchers Mark Ritenour and Sandra Guzmán with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) outline the agenda for the Florida Grower Citrus Show on Jan. 26-27 in Fort Pierce. Ritenour and Guzmán, both of the UF/IFAS Indian River Research and Education Center, will be presenters at the show. Ritenour will discuss maximum residue tolerances for fruit …
By Brad Turner From a family with deep Florida roots, I have over 40 years of experience in commercial citrus production. I learned the industry from the ground up by working in the family groves while studying citrus production at Florida Southern College. I have owned a citrus nursery, my own groves and a citrus caretaking business. I have also …
Lebbeck mealybug, the Bulimulus sporadicus snail and Brevipalpus mite are Florida citrus pests that were discussed at Citrus Expo in August. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Lukasz Stelinski delivered information about the three pests for fellow UF/IFAS entomologist Lauren Diepenbrock. LEBBECK MEALYBUGLebbeck mealybug damages fruit, leaves and stems. The pest causes fruit drop and …
With the new year, Citrus Industry debuts a new look in the January issue! The magazine has been refreshed with a redesign, but readers will still find the same great content they rely upon to produce the best citrus. The January issue features a focus on pest management, with four articles covering this topic. Two of these articles address biological …
Florida’s Citrus Nutrition Box Program that began in the fall of 2019 has shown that regional differences occur around the state with secondary macronutrients and micronutrients. It also showed that manganese and zinc are a concern for almost all areas. Jamie Burrow presented those findings, and numerous others, as part of Citrus Nutrition Day in October at the University of …
By Ruth Borger The week between Christmas and New Year’s is a great time to think about reading, or rereading, a book about Florida citrus or trying out a tasty recipe featuring our favorite fruit. Here are some suggestions that might make it onto your bedside reading table for the new year. Oranges by John McPhee,1966, is considered a classic …
By Ajia Paolillo When we are caught up in the everyday routine of our jobs, it can be easy to forget some essential safety precautions that all agricultural employees should be taking. All agricultural employees could be exposed to pesticides while working in a grove. Proper training is essential to ensure employees understand the risks associated with their jobs and …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers have found that gibberellic acid (GA) applications can improve productivity of HLB-affected Valencia trees. But some growers are concerned that the GA label may not allow that use. Citrus Research and Education Center Director (CREC) Michael Rogers allays that concern. Rogers says some are concerned “because the recommendations that …
A pitch for potentially using the HLB-tolerant Sugar Belle® mandarin hybrid in orange juice (OJ) has been made by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers. A brief presentation titled, “Potential of Using HLB-Tolerant Sugar Belle® in Orange Juice Processing and Effects on Consumer Preference,” is available for viewing. Slides in the presentation indicate that a …
After a year’s postponement because of the COVID-19 pandemic, the University of Florida is hosting the 2022 Flavor Summit – Industry Perspectives on Feb. 22-24.

About four years ago, Fernando Alferez started to test whether citrus trees grown inside protective mesh covers could be kept safe from the HLB-spreading Asian citrus psyllid. New research from Alferez shows that citrus trees grown under individual protective covers (IPCs) show no signs of HLB, also known as citrus greening. Specifically, scientists found that psyllids cannot penetrate the IPCs …
