“GAINESVILLE, Fla. — As consumers increasingly desire local food, opinion leaders can encourage others to eat healthier food and, in doing so, improve the local economy, according to new University of Florida Food and Agricultural Sciences research.
“Opinion leaders” are those who influence others via the respect they earn from those around them, said Alexa Lamm, associate director of the UF Center for Public Issues Education (PIE Center) and the leader of this research.
“Opinion leaders could be critical in bridging the gap between locally grown food and consumers. That’s important because local food sales totaled $6.1 million in 2012, up $1.3 million in four years, according to the U.S. Department of Agriculture. But another study showed only 7.8 percent of U.S. farms targeted local consumers.

GAINESVILLE, Fla. — University of Florida Institute of Food and Agricultural Sciences faculty are on the front lines in the battle against the zika virus, as entomologists study the ability of at least two mosquito species to transmit the virus and ways of reducing pesticide resistance.
They’re also teaching people statewide about how to prevent spreading zika.
As of Aug. 18, 510 American residents had contracted the virus. Florida has 479 zika cases, according to the state health department; 35 people in Florida have contracted zika via local transmission, meaning they didn’t bring it back from overseas.
Scientists at the UF/IFAS Florida Medical Entomology Laboratory in Vero Beach, Florida, have made Zika a top priority. The virus is most likely transmitted by Aedes aegypti – the yellow fever mosquito – and Aedes albopictus – the Asian tiger mosquito.
In February, when the virus started making international news, Roxanne Connelly, a professor of medical entomology and UF/IFAS Extension specialist at the FMEL, put on a statewide zika webinar to tell Extension faculty the do’s and don’ts of trying to contain zika. One of her key messages – that still holds true — was to get rid of standing water and containers that could get water in them because those are mosquito breeding grounds. The other key element was to wear repellant with DEET.
These days, Connelly is working with other UF/IFAS Extension entomologists such as Faith Oi, the Florida Department of Agriculture and Consumer Services and mosquito control districts on zika educational workshops and school newsletters throughout Florida.
LIVE OAK, Fla. — Robert Hochmuth remembers about 30 years ago when researchers with the University of Florida Institute of Food and Agricultural Sciences Suwanee Valley Agricultural Extension Center showed watermelon growers how to use transplants instead of direct seeding. UF/IFAS Extension agents encouraged growers to use plastic mulch instead of bare ground planting, and to switch from overhead to drip irrigation.
“We wanted to help them adopt best management practices that would decrease the use of water, fertilizer and fuel,” said Hochmuth, UF/IFAS Extension center director and regional specialized agent. “In the end, they have not only seen their crop yields increase, but have also helped the environment and reduced the use of resources.”
Over the past 30 years, virtually all Suwannee Valley watermelon growers—about 40—have reduced the use of water, fuel and fertilizer, and improved efficiency by switching to best management practices introduced by UF/IFAS Extension agents, Hochmuth said.
“Nearly one-third of all Florida watermelons are grown in the Suwannee Valley,” said Kevin Athearn, regional specialized agent and co-leader of the watermelon industry study. “So, we wanted to help growers improve the way they grow produce and increase their market share. While most growers started experimenting with plastic much during the 1990s, all had fully transitioned by 2000.”
The results have been astounding.
Growers who participated in a 2016 UF/IFAS survey reported a 50 percent to 80 percent reduction in water use per acre, with the average being 67 percent, Hochmuth said. The growers are saving as much in fuel costs, and 15 percent to 30 percent reduction in applied nitrogen, he said.
GAINESVILLE, Fla. — Apparently, it’s more convenient to Florida residents to save water while brushing their teeth than to cut back on lawn irrigation, according to a new University of Florida Institute of Food and Agricultural Sciences Extension report.
Alexa Lamm, a UF/IFAS assistant professor of agricultural education and communication and Extension specialist, surveyed 932 people deemed to be high-water users in Orlando, Tampa/Sarasota and Miami/Fort Lauderdale.
Respondents were asked how often they engage in water-related behaviors. Among the results, 68 percent saved water when brushing their teeth, but only 29 percent reduced irrigating their lawns in the summer, according to the document, http://bit.ly/2bjQGSm.
To put this data into context, about 50 percent of Floridians’ daily water use is for outdoor purposes, such as landscape irrigation, according to the South Florida Water Management District. The 50 percent figure is 20 percent more than the national average, according to the U.S. Environmental Protection Agency.
GAINESVILLE, Fla. — University of Florida Institute of Food and Agricultural Sciences researchers have introduced a program to help Florida growers maximize the use of nutrients and fertilizers while minimizing the impact on the environment. The results are less fertilizer use and improved crops.
The Four RIGHT (4Rs) program helps growers use the right fertilizer in the right place, at the right time, using the right methods, said Kelly Morgan, state Best Management Practices (BMP) coordinator and UF/IFAS professor of soil and water sciences.
“Fertilizers or nutrients are required in most crop production systems in Florida. While all soils in Florida can supply nutrients for crop production, nutrients may not always be available in adequate amounts for economical crop production,” said Morgan, who is based at the UF/IFAS Southwest Florida Research and Education Center in Immokalee, Florida. “Supplying needed nutrients for crop production involves attention to four major fertilization factors: the right source, right rate, right placement and right timing. Attention to these factors will provide adequate nutrition for crop production while minimizing the risk of loss of nutrients to the environment.”

GAINESVILLE, Fla. — If a city plants trees near a residential area, most homeowners value the likely subsequent boost to their property values, a new University of Florida Institute of Food and Agricultural Sciences study shows.
And they’re willing to pay an average of $7 more per month in taxes for public trees planted in their city.
In the UF/IFAS study, 1,052 surveyed Florida homeowners said they’d like the trees on their land to provide shade and to be healthy, but they’d prefer an increase of $1,600 in their home’s value.
Residents were separated into two surveys. One asked them to consider a hypothetical home improvement project to better the trees on their property, while the other asked a similar referendum question regarding a city program that would increase their utility tax to increase urban forests in public areas near their homes. There were 526 responses to each survey.
PENSACOLA, Fla. — The morning of Aug. 6, snorkelers began combing the waters of Big Lagoon, an inlet southwest of Pensacola, in search of scallops. The week before, another group had done the same at various points along the Santa Rosa Sound. However, neither was interested in harvesting the shellfish, a pastime now prohibited due to the decline in scallop populations off Florida’s Gulf Coast over the last few decades.
These snorkelers are volunteer citizen scientists in the Great Scallop Search, a program co-sponsored by the University of Florida Institute of Food and Agricultural Sciences Extension, Florida Sea Grant, the U.S. National Park Service and the Florida Fish and Wildlife Conservation Commission (FWC).
The volunteers’ task was to count and record the scallops they found on the sea floor. “This data will go to FWC and help officials understand the scallop population in the Pensacola Bay system,” said Rick O’Connor, Sea Grant agent with UF/IFAS Extension Escambia County and co-organizer of the program.
“Knowing how many scallops are there will inform any future efforts by FWC to reseed the area and try to bring the population back,” O’Connor said.
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.
GAINESVILLE, Fla. — You’re heading to college for the first time or returning to campus, and you decide with your parents to get a credit card in your name. A University of Florida Institute of Food and Agricultural Sciences financial expert says you can use credit wisely by sticking to a few key points.
The two biggest mistakes college students make with credit cards are taking on too much debt and failing to make payments even if your credit card bill comes with a low amount due, said Michael Gutter, associate professor of family financial planning and associate dean for UF/IFAS Extension.
