GAINESVILLE, Fla. — Looking to save money and water when you irrigate? UF/IFAS scientists have developed an app for that. Want to know what plants to grow in your garden? You guessed it: UF/IFAS has an app for that as well.
UF/IFAS’ so-called “smart irrigation apps” include an urban lawn app that estimates how long you’ll need to water your lawn to meet current plant water demand. It uses a simplified approach for automated irrigation systems. This urban lawn model uses meteorological data to compute a simple, real-time weekly water balance, said Kati Migliaccio, UF/IFAS associate professor in agricultural and biological engineering and lead designer of the app. Find these apps and others at Smartirrigationapps.org.
“The turf app provides a free resource to determine a schedule to apply the right amount of water to landscapes, which is personalized based on user inputs,” Migliaccio said.

GAINESVILLE, Fla. — Walk into a science museum, and you may read the words “paleontology” or “astronomy.”
But you’re not likely to find the word “agriculture” in any science museum, even though many exhibits relate to agricultural content or practices.
Katie Stofer found this gap when she surveyed 29 science museums in cities of all sizes across the U.S., and her findings are published in a new study in the journal Science Education and Civic Engagement.
“Unfortunately, we have effectively separated agriculture from the other sciences,” said Stofer, a UF/IFAS research assistant professor in agricultural education and communication.
GAINESVILLE, Fla. — Farmers, ranchers, landscapers – and everyone in between – are invited to celebrate Agriculture and Gardening Day at the University of Florida’s homecoming football game, Nov. 7.
UF Athletics and UF’s Institute of Food and Agricultural Sciences are hosting the event and offering discounted tickets to all agricultural workers, their families and friends. (more …)
GAINESVILLE, Fla. — Nearly half of Floridians eat more seafood than they did five to 10 years ago, but 40 percent still do not eat the federally recommended dietary intake of seafood, a new UF/IFAS and Florida Sea Grant-funded survey shows.
Floridians also know seafood is good for them, and they like their seafood caught or harvested in the Sunshine State. But many are not sure they’d know Florida seafood if they saw it, and they’re hesitant to pay the higher cost of local seafood.
“We know that eating Florida seafood is important to consumers,” said Florida Sea Grant Agent Bryan Fluech. Consumers want to support fishermen and the local economy, the survey says.
UF/IFAS experts say they can help educate consumers and the seafood industry to close these gaps.
“Specific educational programs could focus on developing a ‘train-the-trainer’ model for restaurant and retail staff,” said Fluech. That’s because most consumers purchase their seafood from restaurants and grocery stores, although they are not confident that they are getting accurate information from these sources. “Such a program would help these workers better address customer questions and needs, while promoting Florida seafood.”

GAINESVILLE, Fla. — Growers in Florida’s $100 million-a-year avocado industry could see a rise in the price of avocados in the short term due to a reduction in domestic production, because of the deadly Laurel Wilt pathogen, a new University of Florida study shows.
But any noticeable price increase probably wouldn’t last because increased imports from the Dominican Republic are likely to temper any price increases.
Edward Evans, a UF/IFAS associate professor in food and resource economics, is quick to note, however, that he conducted his study before the recent discovery of a medfly outbreak in the Dominican Republic. The outbreak led the U.S. Department of Agriculture to restrict imports of green-skin avocados from that country. This avocado is similar to the type produced in the Sunshine State.

GAINESVILLE, Fla. — As a good source of protein, Vitamin A, calcium, iron and fiber, broccoli is so full of nutrients, some call it a “super food.”
It’s also popular at the supermarket, whether it’s grown in America or overseas. But Americans are willing to pay $1 more per pound for U.S. organic broccoli than that from China and Mexico and up to 32 cents more per pound than that grown in Canada.
UF Institute of Food and Agricultural Sciences researchers conducted a national online survey in 2010 in which they posed questions about organic broccoli to 348 participants. They wanted to know the impact of “Country of Origin Labeling” on the price people were willing to pay for organic broccoli.
Foods sold in grocery stores come in packages labeled “organic,” if it applies. The packages also tell the buyer the country where the food was grown — a concept called “Country of Origin Labeling.” But some consumers remain confused about whether the broccoli they’re buying meets U.S. government standards for organic products, said Zhifeng Gao, a UF associate professor of food and resource economics.

GAINESVILLE, Fla. — As the University of Florida prepares to embark on the 2015-16 academic year, the College of Agricultural and Life Sciences offers several courses and majors that reflect how the institution adapts to industry and stakeholder needs.
The courses and majors aren’t brand new for this fall. They evolved during the past few years. But they reflect the growing menu of courses and majors offered to the more than 3,700 undergraduate students expected to enroll at UF CALS this fall.
Just to name a few of the relatively new majors and course offerings, UF CALS offers a major in marine sciences that leads to a bachelor’s degree, a new undergraduate certificate titled “Challenge 2050: Global Leadership and Change” from the Challenge 2050 Project and three new majors offered in the Food Science and Human Nutrition Department that were previously specializations under one major – Food Science and Human Nutrition.

GAINESVILLE, Fla. — Muscadine grape seed oil supplies a form of Vitamin E, giving scientists another clue to reducing obesity, a new University of Florida study shows.
The oil may help mitigate the formation of new fat cells because it produces tocotrienol, an unsaturated form of Vitamin E, said Marty Marshall, a UF professor of food science and human nutrition.
“Thus, consuming foods made with muscadine grape seed oil could curtail weight gain by reducing obesity,” Marshall said.
Muscadine grape seed oil would be a valuable addition to the market of edible oils because it is a unique source of tocotrienol in addition to being a good source of mono- and polyunsaturated fatty acids, Marshall said. In addition, scientists anticipate that muscadine grape seed oils fortified with additional tocotrienol from underutilized muscadine varieties could be developed to help stem obesity.
Before this study, scientists attributed most tocotrienol benefits to red palm and rice bran oil. In fact, recent studies have shown that rice bran oil helps lower cholesterol. With the new findings, muscadine grape seed oil could be considered a superior source of tocotrienol, said Marshall, a faculty member at UF’s Institute of Food and Agricultural Sciences.
GAINESVILLE, Fla. — Wet wood treated with the pesticide chromated copper arsenate (CCA) loses arsenic three times more than dry wood; so if it rains, you can expect more arsenic on your wood deck surface, a new University of Florida study shows.
That may pose a potential danger to anyone who plays or walks on the deck, and that most often means children or pets, said Julia “Ky” Gress, a doctoral student in soil and water sciences at the UF Institute of Food and Agricultural Sciences.
Gress led an experiment in which she and her colleagues used standard wipe methods to collect arsenic from the surface of wood from a 25-year-old South Florida deck. Although the CCA-wood came from only one deck, it is representative of wood decks constructed before 2004, Gress said.
Before wiping the wood, researchers put water on it, then wiped it to see how much arsenic was present. They then cleaned different pieces of the decking with either tap water or a bleach-water solution, followed by pressure washing.
Results showed water alone caused three times more arsenic to form on the surface of wet wood than dry wood, and the use of bleach caused formation of chromate, another carcinogen. They also found that these chemicals remained on the wood surface for an hour after it was cleaned.
GAINESVILLE, Fla. — A University of Florida Institute of Food and Agricultural Sciences researcher has identified the protein that the liver uses to load iron, thereby opening the door to potential strategies to treat “iron overload” disorders.
One form of these genetic disorders is hereditary hemochromatosis. Not everyone who inherits the gene will get the disease, but those who do so inherit the defective gene from both parents. Hereditary hemochromatosis is found most often in people of Northern European descent.
Over several years, those with the disorder will see excess iron get into the liver, heart, pancreas, joints and pituitary gland, leading to health problems such as cirrhosis of the liver, liver cancer, diabetes, heart disease and joint disease. People with the disease can get their blood drawn routinely to get rid of the excess iron.
“For 150 years, we did not know how iron got taken up by the liver — how it got in there,” said Mitchell Knutson, a UF associate professor in food science and human nutrition. “We knew there was a protein that took it up into to the liver. But nobody knew what that protein was. It’s such a fundamental question, and people just didn’t know the answer.”
