GAINESVILLE, Fla. — Facial recognition software is no longer a thing of the future. But what if similar technologies could one day help farmers identify pests in the field?
Steve Futch, multi-county citrus agent with the University of Florida Institute of Food and Agricultural Sciences Extension, thinks it’s possible. And thanks to the new UF/IFAS Extension Entrepreneurship Program, he and other UF/IFAS Extension faculty now have more of the tools they need to make their ideas a reality.
“One of the missions of UF/IFAS Extension is to connect Floridians with science-based information that will improve their quality of life. Our relationships with our clientele are always evolving, so we are always reassessing and rethinking how we can better serve our audience,” said Nick Place, dean for UF/IFAS Extension. “Entrepreneurial thinking can help us get out of our comfort zone and approach problems in new and creative ways.”
Jan. 17 to 19, UF/IFAS Extension faculty members from around the state heard presentations from several UF entrepreneurship experts, including Elio Chiarelli, entrepreneurship specialist with the UF/IFAS Center for Leadership. As a doctoral student in the UF department of agricultural education and communication, Chiarelli’s research focused on successful entrepreneurship within agriculture and natural resources.
GAINESVILLE, Fla. — Nearly a century ago, a group of Polk County citrus growers raised about $14,000 to buy land for a research station. Now, the University of Florida Institute of Food and Agricultural Sciences will celebrate the 100th anniversary of the UF/IFAS Citrus Research and Education Center.
In 1917, UF/IFAS established the Citrus REC. Originally, only a few UF/IFAS scientists worked at the Lake Alfred site, then called the Citrus Experiment Station.
Today, the research center employs 250 people and is also home to the scientific research staff of the Florida Department of Citrus. It is the largest facility in the world devoted to a single commodity, citrus.
“The UF/IFAS Citrus REC has a long, proud tradition of outstanding science and outreach, and the faculty there show every day why the quality of work performed for the next 100 years will be as good or better than the first century at the facility,” said Jack Payne, senior vice president for agriculture and natural resources.
FORT PIERCE, Fla. – Rhuanito “Johnny” Soranz Ferrarezi has joined the University of Florida Institute of Food and Agricultural Sciences to lead citrus horticulture research in the world’s premier grapefruit production region.
Ferrarezi brings more than 10 years of experience to his new position as assistant professor of citrus horticulture to the UF/IFAS Indian River Research and Education Center in Fort Pierce. He joins two additional new hires at UF/IFAS IRREC who will work as a team to assist growers as they manage citrus greening, or Huanglongbing (HLB), the industry’s most formidable pathogen.
“Dr. Ferrarezi is capable and exuberant about his work to manage crop production,” said Ronald Cave, UF/IFAS IRREC director. “He has demonstrated a fervent commitment to agriculture in his native Brazil, which is also one of the world’s most productive citrus regions, and we are confident his work in Florida will be significant.”
GAINESVILLE, Fla. — A trio of projects aimed at helping Florida producers cope with the bacterial disease known as citrus greening topped the list of stories shared by the University of Florida Institute of Food and Agricultural Sciences in 2016.
This year marked the beginning of the state’s second decade battling greening disease, which is also known as Huanglongbing or HLB. Other top stories for the year involved invasive organisms causing negative impacts to Florida’s economy and environment, and even the health of its residents.
Here are the top 10 UF/IFAS 2016 stories:

GAINESVILLE, Fla. — Fifteen early career scientists at the University of Florida Institute of Food and Agricultural Scientists have been awarded grants to help solve global issues such as thwarting invasive pests, improving crop varieties, battling citrus greening and preserving our environment.
The faculty members will receive about $50,000 each as part of UF’s Early Career Scientist Seed Fund program to help develop new faculty research, said Jackie Burns, UF/IFAS dean for research. UF/IFAS works with the UF vice president for research on the program.
“This year’s competition was highly competitive, with 25 early career scientists presenting excellent proposals,” Burns said. “After a rigorous review by a panel of UF/IFAS scientists, I am pleased to announce 15 awards. The research projects represented by these awards demonstrate the breadth of UF/IFAS research programs.”
GAINESVILLE, Fla. — A time-lapse polarized imaging system may help citrus growers detect greening before the plant’s leaves show symptoms, which should help growers as they try to fend off the deadly disease, a new University of Florida Institute of Food and Agricultural Sciences study shows.
For the new study, Won Suk “Daniel” Lee and Alireza Pourreza wanted to know how early citrus leaves with greening can be detected while they are pre-symptomatic. So they inoculated plants with the greening disease and put those leaves through a time-lapse imaging system.
There, they found starch in the leaves, an early sign of greening, said Pourreza, a former post-doctoral researcher in the UF/IFAS agricultural and biological engineering department. In their study, UF/IFAS researchers detected greening about one month after they infected the trees, he said.
Timely detection and removal of greening-infected trees are necessary to manage the disease, said Lee, a UF/IFAS agricultural and biological engineering professor and an author on the study.

GAINESVILLE, Fla. — Citrus grower James Shinn remembers days when he and his workers would rush out as early as 5 p.m. to turn water pumps on to irrigate his crops. “We had no idea when the temperature would drop, so we had to get out there early and get the water going.”
Now, researchers with the University of Florida Institute of Food and Agricultural Sciences are helping state growers save millions of dollars via a tool to gauge weather in agricultural areas.
The Florida Automated Weather Network (FAWN), was started in 1998 to provide weather decision-making data in agricultural regions, said Rick Lusher, director of FAWN. While all National Weather Service tools are located at airports, FAWN stations are located in agricultural areas, he said.
“We estimate that if farmers use FAWN tools to determine when to irrigate their crops, they can save millions of dollars and millions of gallons of water,” Lusher said.

GAINESVILLE, Fla. — A chemical treatment known as a bactericide could help preserve citrus trees from the potentially deadly and costly greening disease, a new University of Florida Institute of Food and Agricultural Sciences study shows.
Citrus is estimated as a $10.9 billion-a-year industry in Florida and the finding could be key to helping the state’s citrus growers and its economy. Citrus greening has cost Florida $3.6 billion in economic damage since it was first discovered in 2005, according to previous UF/IFAS studies. It is projected that more than 80 percent of citrus trees have been infected by greening.
Nian Wang, a UF/IFAS associate professor of microbiology and cell science, led the latest study, which found that when a bactericide – in this case, oxytetracycline — is injected into the trunk of greening-infected citrus trees, it helps keep the trees alive by thwarting greening, also known as Huanglongbing, or HLB.
GAINESVILLE, Fla. — The University of Florida Institute of Food and Agricultural Sciences has added another soldier in its battle against citrus greening by hiring world-renowned entomologist Bryony Bonning. She has been named Eminent Scholar with tenure in the UF/IFAS entomology and nematology department.
Currently, Bonning is a professor of entomology at Iowa State University and director of the National Science Foundation Center for Arthropod Management Technologies, where she oversees cutting-edge research on insect physiology and pathology, and biotechnology. Bonning is a recognized authority in the development of new technologies for insect pest management, and a fellow of the Entomological Society of America and the American Association for the Advancement of Science.
“Dr. Bonning brings an outstanding record of accomplishment and cooperation, and we are confident she will work tirelessly to develop solutions for citrus pest management,” said Blair Siegfried, chair of the UF/IFAS entomology and nematology department. “Her combined experience and achievements make her ideally suited and deserving of the position.”
GAINESVILLE, Fla. — In their quest to develop higher quality mandarins, University of Florida Institute of Food and Agricultural Sciences researchers are zeroing in on the traits that will help them breed the best fruit.
Last year, they released the mandarin cultivar currently known as ‘7-6-27,’ which UF/IFAS researchers say is soaring with interest, and with more than 100,000 trees already ordered.
In a newly published study, Fred Gmitter, a UF/IFAS horticultural sciences professor, and his colleagues, including doctoral student Yuan Yu, found genetic markers for fruit quality traits that will be useful in future cultivar-breeding efforts.
Scientists wanted to know whether, for example, genetic markers – or “signposts,” as Gmitter calls them — for qualitative and quantitative traits in one group of mandarins lined up with these traits in other mandarins. Qualitative traits would be such things as peel or flesh color, while quantitative traits would include weight, size or shape.
