FROM THE DIRECTOR'S DESK
What a bustling spring season at IRREC! Our faculty, graduate students and staff are all aflush with a highly successful Florida Citrus show, current research projects, collaborations, professional meetings, rising graduate students, and plans to serve our local industry and global research communities!
Along with our partner organizations, AgNet Media, the USDA-ARS Horiculture Research Laboratory, and the Indian River Citrus League, we pulled off the most successful Florida Citrus Show in history! More than 700 attendees turned out for a 1-day fun, festive, and upbeat tailgate-style trade show. Perfect weather seemed to be a miracle. And a long list of compelling educational presentations was delivered to a full IRREC auditorium and USDA conference room. This year was the first for vegetable production best practices sessions.
I want to recognize IRREC faculty members Dr. Mark Ritenour and Dr. Sandra Guzmán for their diligence to plan a spectacular line-up of speakers for the Vegetable and Citrus Education sessions. In addition, Dr. Guzman’s Smart Irrigation and Hydrology Laboratory team presented an interactive, highly engaging exhibit in the IRREC rotunda and a greenhouse water farming demonstration. Other faculty presented displays of their research activities.
UF/IFAS Senior Vice President of Agriculture and Natural Resources Dr. Scott Angle opened the Florida Citrus Show with “The Next Era in Florida Citrus,” noting new technology and plant breeding techniques that will advance fresh fruit production.
At the event’s midpoint, I had the privilege to induct Dr. Pasco Avery into the Southern Friends of IPM Hall of Fame! Dr. Avery leads biological control research for pest insects from the IRREC Entomopathogenic Fungi Research Laboratory. His role as an insect pathologist has elevated him to a status as a leading expert for biological control with entomopathogenic fungi.
In November, we will welcome Dr. Flavia Zambon to our faculty as Assistant Professor of Production Horticulture of Citrus and Other Tree Crops. Dr. Zambon led our grapefruit research for “The MAC Project,” and will continue the research in her new position. In addition, Dr. Zambon will oversee The Millennium Block, Citrus Under Protective Screens (CUPS), and efforts to identify new tree crops for the Indian River region.
Our faculty members are dazzling. And so too are our graduates. We rejoiced along with Dr. Rossi, who mentored his Ph.D. student John Santiago as he crossed the commencement stage in Gainesville to emerge as Dr. John Michael Santiago!
I will close this letter with encouragement to peruse this IRREC News, 2023 Spring Flush Edition. Although I cannot include in this letter all the accomplishments and important work our faculty, staff and graduate students carry out daily, there is much more to admire. Please enjoy this newsletter in which we showcase our faculty, staff, and graduate students’ work and contributions to agriculture and natural resources.
Thank you for reading.

THE 2023 FLORIDA CITRUS SHOW
Dr. Scott Angle presented "The Next Era in Florida Citrus"
Record attendance, a festival-like vibe, and an inventive menu of freshly prepared tailgate-style foods regaled 2023 Florida Citrus Show attendees on April 13.
“The 2023 Florida Citrus Show was an extraordinary success. Under perfect skies, a record attendance turned out to enjoy a rousing tailgate trade show with delicious food offerings from each vendor. The presentations were informative and well-attended. The positive comments keep rolling in,” said Ronald D. Cave, UF/IFAS Indian River Research and Education Center (IRREC) Director.
“AgNet Media, the UF/IFAS IRREC, the Indian River Citrus League, and the United States Department of Agriculture Agricultural Research Service Horticultural Research Laboratory planned an exemplary event for all in attendance,” Cave said.
Extension Agents Ken Gioeli and Kate Rotindo taught participants how honeybee flavor profiles are linked to the flowers bees are pollinating. For example, honey bee hives placed in orange groves will have a distinctive flavor profile termed "orange blossom" honey.
Honey bees are essential to Florida's agriculture. From vegetable crops to tree crops like citrus, any plant requiring pollination can benefit from honey bees.
Dr. Nicole Quinn's presentation included her work to control the Lebbeck mealybug, a citrus pest.
Dr. Rossi and the Plant Root Biology Laboratory team presented their work with plant root biology for crop tree roots.
Robin Loftin and her team from AgNet Media led a highly successful Florida Citrus Show for the first time.
According to officials with AgNet Media, more than 700 attended The Florida Citrus Show (FCS). And while most visitors hailed from Florida, about 12 registrants reside in California and Georgia. The show attracted four internationals: one from Angola, others from Japan, Ireland, and Brazil.
The FCS tradition is a focus on citrus production. And with Florida’s diverse offerings of high-value specialty crops, show leaders added vegetable educational sessions to this year’s line-up.
Vegetable production topics included pest management for nematodes, area-wide whitefly management, and a new invasive species—Thrips parvispinus.
Scott Adkins, plant pathologist with the United States Department of Agriculture Agricultural Research Service Horticultural Research Laboratory (USDA-ARS), presented a live demonstration with canines that successfully identified virus-infected plants by smell. Adkins’ presentation, “What’s new in vegetable viruses and detector dogs,” provides producers with a method to detect and curtail plant disease in commercial production operations.
Just before noon, aromas of meats sizzling on barbeque grills, stewing seafood dishes, and simmering swamp cabbage swirled about the tented trade show. OmniLytics associates prepared succulent, farm-raised pink shrimp cocktails in clear, martini-size holders. From the many sumptuous tapas, show attendees selected Southern Citrus Nurseries’ vegetable spring rolls for the top tail-gate cuisine offering. But the entire lunch innovation was a success, said Cave.
The tailgate luncheon was extended to two hours and was immensely popular with attendees.
UF/IFAS IRREC professors Mark Ritenour and Sandra Guzmán organized the show’s Citrus Section Educational Sessions. “We enjoyed the opportunity to showcase the tireless work of UF/IFAS researchers and extension programs in supporting Florida’s signature crop,” Guzmán said.
UF/IFAS IRREC Citrus Horticulture News
Citrus horticulture expert selected for UF/IFAS Indian River District horticulture position
A scientist with a career invested in Florida citrus production will join the research team from the heart of Florida’s renowned grapefruit production region.
A native of Brazil’s famous citrus production region, São Paulo State, Flavia Zambon is the selected candidate for the IRREC assistant professor of production. In announcing Zambon’s new IRREC appointment, to begin in November, Ronald D. Cave, IRREC director, said Zambon is the strongest candidate for the position owing to her many years of experience with citrus research in all of Florida’s citrus production regions.
Dr. Zambon presents The MAC Project in this video that celebrates International Postdoctoral Week
Citrus australia visits the millennium block
Dr. Mark Ritenour and Dr. Lorenzo Rossi hosted members of Citrus Australia, a professional trade organization that serves citrus growers in Australia and New Zealand.
Citrus Australia members interests are current research to manage two citrus diseases: canker and citrus greening. After a question-and-answer session that included Dr. Salman Al-Shami, an IRREC postdoctoral research associate, Tom James, IRREC biological scientist, and Mac Hossain, Agricultural Research Assistant, the visitors requested a tour of the UF/IFAS-IRREC Millennium Block, an active research grove of more than 5,500 grapefruit, orange, and mandarin trees.
Tom James explained to the Australian citrus growers that while some trees appear to be thriving, the research must continue for three more years to gather reliable data for the industry.
The IRREC Millennium Block was first planted in 2019. The trees have entered their fruit-bearing years.
IRREC researchers explained how growers manage HLB and canker in their operations.
The group asked about the impact of HLB and canker on production operations along the Indian River District and about pest control and plant nutrition related to these diseases. In particular, they were interested in promising research to control the Asian citrus psyllid.
The IRREC researchers also introduced the group to screenhouses that exclude the psyllid from trees growing inside. The research is called Citrus Under Protective Screens, or CUPS. IRREC researchers explained that it is possible to produce high quality citrus inside a CUPS model, but that mites and higher temperatures are problematic in this scenario. Hurricanes and high winds are also a concern with CUPS.
findings from the millennium block and the mac project
Citrus growers in Florida’s “River” production region along the Indian River Lagoon develop unsurpassed flavor and texture in a fresh grapefruit product coveted worldwide.
Growers in the area have watched the industry they love steadily decline in the last two decades. They await scientific results from two active research projects involving more than 39,000 trees, expected to reveal which new varieties will tolerate pressure from the most serious citrus disease worldwide.
The citrus tree disease is called huanglongbing, or HLB, or citrus greening. It has cost Florida millions in fruit sales that once supported the economy with jobs for its citizens. It has hit hard an industry that so many consider a birthright and a career shared by generations of families and their communities.
40,000 trees included in two field experiments. But among the nearly 40,000 trees researched in two trials—hope also grows. Some trees are expected to stand against the disease, tolerate it, thrive, and produce market-ready fresh fruit.
To usher in National Invasive Species Awareness Week, scientists in Florida—the epicenter of invasive plant and insect infestations hosted Matthew Thomas, a leader who was hired to head the more than 120 researchers working with invasive species statewide.
Thomas directs the UF/IFAS Invasion Science Research Institute, the university’s young and rising force to investigate, control and monitor surroundings rife with invasive organisms.
"I was really excited to see the Norman C. Hayslip Biological Research and Containment Laboratory. I used to do a lot of hands-on work in biocontrol. In the last 15 years my research has moved away from biocontrol, but I am still working in pest control, although in a slightly different way. It was interesting for me to come back to biocontrol and see a containment facility–to see a diversity of projects and the diversity of agents evaluated and screened inside isolation," said Dr. Thomas.
"I met graduate students who are really energized and enthusiastic to develop biocontrol solutions. It was great to see an infrastructure that really allows that—there are very few well-regulated, well-maintained quarantine facilities to bring in exotic natural enemies. It’s a hugely valuable resource for the state and beyond—for the country." --- Dr. Matthew Thomas
Dr. Ritenour said the tour was excellent as Syngenta tour guides led the group through interior research labs, greenhouses and fields. Syngenta representatives explained how they run through "initial selection," or screening for compounds used in agrochemicals. Those tasks are carried out in Europe. But many field experiments are conducted at the local laboratory. Dr. Ritenour added that researchers in the laboratory are able to expedite research in the Vero Beach laboratory owing to yearlong warm weather.
Another point of interest during the tour was that Syngenta collaborates with pest control companies and raises roaches and ants for use in the experiments.
The Quinn Biological control Research laboratory
UF/IFAS Researchers and local Extension invite nursery, citrus growers and master gardeners to a Lebbeck mealybug diagnostic kit demo
Florida citrus and nursery growers need to develop proactive management plans for Lebbeck mealybug, an invasive pest that can cost the fruit and ornamental industries thousands of dollars in damages to fruit trees and landscaping plants.
A team of research scientists is working to prevent such scenarios with an early diagnostic kit to identify the invasive mealybug on trees and nursery plants. The insect is hard to detect and identify during its early life stage because it is so tiny that it is often concealed in small crevices in plants.
Dr. Lance Osborne collaborates with Dr. Quinn and Diepenbrock on research and a grant to distribute the Lebbeck mealybug to nursery growers and master gardeners.
Collaborator Dr. Lauren Diepenbrock assists participants as they identify a Lebbeck mealybug
Research collaborator Dr. Muhammad "Zee" Ahmed presents on the Lebbeck mealybug.
Workshop participants extract Lebbeck mealybugs from nursery citrus trees and use the diagnostic kit solution to get a positive identification.
If the kit solution turns green when applied to crushed mealybug, the participants gain a positive identification of the Lebbeck mealybug.

The Rossi Plant Root Biology Laboratory
Most of the world’s olives grow in southern European countries, such as Spain and Italy.
In the United States, California has more than 30,000 acres dedicated to the commodity. But Florida may be the next agricultural region for small-scale commercial olive production.
Lorenzo Rossi, a native Italian who immersed himself early in life in olive production and the culture that surrounds rural Tuscany, believes the evergreen tree with oblong, sage-colored leaves may be a good prospect for Florida growers.
Robert Gilbert, UF/IFAS dean for research, and Andra Johnson, UF/IFAS dean for Extension, recently approved a nearly $70,000 grant for Rossi’s research proposal, “Evaluating olive (Olea europaea L.) as a new cash crop for Florida.” In addition to the UF grant, The Florida Olive Council will support the project with $5,000.
