GAINESVILLE, Fla. — Brenda Rogers has been named director of the University of Florida Institute of Food and Agricultural Sciences Extension south central district. This district encompasses 11 Florida counties in southwestern Florida, from Pasco County in the north down to Collier County in the south.

Rogers grew up in Manatee County, where her father was a third-generation dairy farmer and she was a member of her local 4-H club. This upbringing instilled a love of the land and the life it represents, she said, and gave her firsthand experience with the region’s people and the challenges they face.

“We are extremely pleased to have Brenda serving as our district Extension director for the south central district,” said Nick Place, dean and director of UF/IFAS Extension. “She has an outstanding background as a former Extension faculty member, county Extension director and former county department director, all highly aligned with this position. Moreover, she has a tremendous view of the many opportunities facing Extension and ideas on how we can best get there. We are very excited to have her as a key member of our statewide leadership team for UF/IFAS Extension.”

GAINESVILLE, Fla. — With citrus growers trying to save their groves in the wake of the deadly greening disease, a University of Florida Institute of Food and Agricultural Sciences researcher has found a new technique that could help growers answer a vexing question – why so much fruit is dropping to the ground prematurely.

If we know why fruit is dropping, we can better figure out what caused it to drop – factors such as temperature, wind, humidity, rainfall, citrus greening or other factors, said Wonsuk “Daniel” Lee, a UF/IFAS professor of agricultural and biological engineering.

While there is no known cure for greening, it’s important to know its locations and how much damage the disease caused at those sites so growers can mitigate the disease, a new study led by Lee says.

One indicator of the severity of damage is the number of dropped fruit. The other is how much the fruit has decayed once on the ground.

AUGUSTINE, Fla. — During Florida’s wet summers, your backyard or patio area can easily become a breeding area for container mosquitoes, said Jim DeValerio, a University of Florida Institute of Food and Agricultural Sciences Extension horticulture agent. Though there are no reports that mosquitoes are transmitting the Zika virus in Florida, residents should still take measures to prevent mosquitoes from living and breeding in their home landscapes, he said.

Here are DeValerio’s five tips homeowners can use to reduce mosquitoes on their properties.

GAINESVILLE, Fla. — Of all the invasive plants in Florida’s waterways, hydrilla costs the most to contain — $66 million over a seven-year period, a University of Florida Institute of Food and Agricultural Sciences researcher says.

But UF/IFAS researchers are finding new ways to use less chemical treatment, and thus less money, to manage hydrilla.

From 2008 to 2015, state and federal water resource managers spent about $125 million to control invasive aquatic plants, according to an April Extension document co-written by Lyn Gettys, a UF/IFAS assistant professor of agronomy and aquatic weed specialist. You can find the document here: http://bit.ly/28UsGoh.

Of that $125 million, about $66 million goes to control hydrilla, according to the Florida Fish and Wildlife Conservation Commission.

ST. AUGUSTINE, Fla. — Maia McGuire was leading middle-schoolers on a local beach clean-up when she noticed a cluster of deflated balloons on the sand. It’s not unusual to find balloons on the beach, McGuire said, but these were different: Each balloon was printed with the name of a nursing home in Texas.

“Those balloons were probably the weirdest thing I’ve found on one of our beaches,” McGuire said. However, this discovery made it clear that, while beach clean-ups are often done by locals, keeping beaches clean is everyone’s responsibility, she said. That’s because, in the environment, trash travels, and one person’s trash can easily become another person’s clean-up hundreds of miles away.

McGuire works in St. Johns and Flagler counties as a University of Florida Institute of Food and Agricultural Sciences Extension Sea Grant agent. Part of her job is to help the community keep its beaches and oceans clean. You can do your part this summer by following these five tips.

GAINESVILLE, Fla. — Jim Davis is studying hard for his public health pest control license exam. In the past, getting this license wouldn’t be a usual part of his job. But with the recent public concern about the mosquito-borne Zika virus, expertise in mosquito control could soon be the norm for many University of Florida Institute of Food and Agricultural Sciences Extension faculty like Davis.

Davis and several others have already signed up for the UF/IFAS Extension Zika Challenge, a new program that helps Extension faculty become public health pest control license (PHPC) holders. Faculty will use this training and other outreach strategies to educate their communities about mosquito control.

Ken Gioeli, a UF/IFAS Extension St. Lucie County agent, wondered if other Extension agents would benefit from this training after he got his own PHPC license. The Zika Challenge grew out of discussions Gioeli had with Anita Neal, director for UF/IFAS Extension’s south district, and Roxanne Connelly, a professor and Extension specialist at the UF/IFAS Florida Medical Entomology Laboratory in Vero Beach, Florida. Gioeli and Connelly designed the program.

UF/IFAS, Pinellas Sheriff’s office create urban farms in Pinellas County

GAINESVILLE, Fla.— Residents in a county on Florida’s Gulf Coast are getting the help they need to access healthier foods via a collaboration between the University of Florida Institute of Food and Agricultural Sciences Extension and the Pinellas Sheriff’s Police Athletic League. The two entities have teamed up to create an urban farm in Pinellas County.

Urban farms promote an abundance of food for people in need while raising awareness of health and wellness. “It is an opportunity to teach families and children the values of nutrition and establish a level of commerce for produce distribution,” said Mark Trujillo, a public health regional specialist for UF/IFAS Family Nutrition Program.

Trujillo introduced the executive director of the Pinellas Sheriff’s PAL, Neil Brickfield, to an empty U-Pick farm in Lealman, Florida, Pinellas County. After discovering the potential that the farm had to help the county, Brickfield then began to work with UF/IFAS to identify the needs of the farm and community.

Because Lealman, Florida is considered a food desert, the idea of an urban farm was essential for the area, Trujillo said. According to Brickfield, the citizens in Lealman are more than a mile from a local grocery store. “So, the urban farm is an opportunity for people to have fresh produce readily available,” Brickfield said.

UF survey shows most Floridians want to know more about genetically modified foods

Topic(s): Agriculture, Crops, Families and Consumers, Food Safety, IFAS, New Technology, Nutrition, Research

GAINESVILLE, Fla. — While almost half of Floridians acknowledge buying genetically modified foods, a recent survey by the Center for Public Issues Education in Agriculture and Natural Resources at the University of Florida reveals that most people want to know much more about those foods.

“The study shows that Floridians believe they don’t know much about genetically modified foods and their benefits,” said Joy Rumble, assistant professor in agricultural education and communication at the UF Institute of Food and Agricultural Sciences. “Many people are favorable to supporting research, and they think it’s essential that government support it. Floridians see a place for GM foods, but they do have hesitations.”

The PIE Center surveyed 500 Floridians on their perceptions of genetically modified foods. Respondents were largely unsure about the potential benefits of genetically modified food, with more than 40 percent neither agreeing nor disagreeing that food technology such as GMOs allows people to live longer or better lives.
