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.”

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.

UF/IFAS expert has five tips for keeping your beach clean this summer

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.

Blueberries’ health benefits better than many perceive

Blueberry bush.

GAINESVILLE, Fla. — Consumers know some of the benefits blueberries provide, but they’re less aware of the advantages of reverting aging, improving vision and memory, a new University of Florida study shows.

Shuyang Qu, a doctoral student in agricultural education and communication at the University of Florida Institute of Food and Agricultural Sciences, led the study. Joining Qu were Joy Rumble, a UF/IFAS assistant professor of agricultural education and communication, and Tori Bradley, a master’s student in the UF/IFAS food and resource economics department. Rumble’s Florida Specialty Crop grant gave the opportunity to examine consumers’ knowledge of blueberry health benefits.

Qu and her colleagues wanted to determine how much consumers know about blueberry health benefits and see if there’s a knowledge gap with blueberry health benefits among demographic groups. Using their findings, they will identify promotional opportunities for Florida blueberries.

Researchers surveyed more than 2,000 people in 31 states – mostly on the East Coast and in the Midwest – to see what they know about the health benefits of blueberries. Most were aware of the benefits of blueberries in warding off cancer and lowering the risk of heart disease. The UF/IFAS study also found that low-income populations tend to know less about blueberry health benefits.

UF/IFAS expert: Whitefly species likely to cause growers problems

WHITEFLY 052516

GAINESVILLE, Fla. — A University of Florida Institute of Food and Agricultural Sciences expert predicts the Q-biotype whitefly discovered in April in Palm Beach County will likely cause problems for growers.

The Q-biotype whitefly – not to be confused with the B-biotype, which came to Florida in the mid-1980s – is now being seen outside greenhouses and nurseries and poses a threat to ornamental plants and agricultural crops. After the B-biotype was found in Florida in the 1980s, scientists saw big increases in the diversity and frequency of whitefly-transmitted viruses in many Florida crops, said Jane Polston, a UF/IFAS plant pathology professor. Crops like beans, tomato, watermelon and squash were hit hard by these viruses after the appearance of the B biotype.

“This Q-biotype is a pest that damages crops and resists many of the insecticides that are effective on the B-biotype, the whitefly that is common in many ornamental and vegetable crops,” Polston said. “And like other whiteflies, it is capable of transmitting viruses from one plant to another.”
