Wet ‘dry season’ damaged valuable ornamentals

Topic(s): Economics, Extension, IFAS, Landscaping, Lawn & Garden, RECs, Research

GAINESVILLE, Fla. — Florida’s winters are usually dry, but the wet winter of 2015-2016 helped spread pathogens that destroyed ornamental plants in Miami-Dade County. That’s a problem in an area where the industry generated an estimated $998 million annually in sales in 2015, University of Florida Institute of Food and Agricultural Sciences researchers say.

Damage figures are not yet available from the 2015-2016 winter rains, but UF/IFAS scientists have found the pathogens Phytophthora and Pythium caused the most destruction. Rain spreads those pathogens, said Georgina Sanahuja, a post-doctoral researcher at the UF/IFAS Tropical Research and Education Center in Homestead, Florida.

Meteorologists consider Florida’s “dry season” to run from Oct. 1 to March 1 and the rest of the year to be the “wet season.” But last year, the “dry season” wasn’t so dry, because of El Niño, which brought more rain than South Florida has seen since records were kept starting in 1932, a new study published in the journal HortTechnology says.

GAINESVILLE, Fla. — To protect personnel on Southeastern military installations from tickborne diseases, a federal program has awarded a five-year, $2.45 million grant to a team of researchers with the University of Florida Institute of Food and Agricultural Sciences and other institutions. The grant was provided by the federal Strategic Environmental Research and Development Program, an initiative supported by the U.S. Department of Defense, Department of Energy and the Environmental Protection Agency.

The scientists will determine how tick populations are affected by invasive plants, fire and the availability of host animals in specific locations; this information will help the team assess tickborne disease risk under future climate conditions.

Portions of the project based at UF/IFAS will receive more than $700,000 in funding, said Jack Payne, UF senior vice president for agriculture and natural resources. “This project requires an interdisciplinary approach to account for all of the relevant ecological factors that influence the risk of people being exposed to tickborne diseases,” Payne said. “An ideal team of subject-matter experts has come together here, and I’m proud that UF/IFAS is involved.”

Participating faculty represent UF/IFAS, the University of Illinois at Urbana-Champaign and Boston University, Payne said. Field studies will take place on more than a dozen U.S. Department of Defense properties where the lone star tick is found, including sites in six states where the tick co-exists with an invasive plant known as cogongrass — Alabama, Florida, Georgia, Louisiana, Mississippi and South Carolina. Researchers will also assess Midwestern sites where the tick is present but the invasive plant is not.

The team will conduct three years of field work to assess tick populations, white-tailed deer populations, plant communities, plant invasions, and pathogen presence in ticks, said Jackie Burns, UF/IFAS dean for research and director of the Florida Agricultural Experiment Station. Two years of data analysis will follow, she said, with researchers using models to develop disease-exposure risk maps for future time frames and climate conditions, as well as early-warning systems and management guidelines.

Florida peaches pack a punch as a succulent snack

Topic(s): Agriculture, Crops, Extension, Families and Consumers, IFAS, Nutrition, Research

GAINESVILLE, Fla. — Florida peaches make for a succulent snack, say consumers surveyed by a University of Florida Institute of Food and Agricultural Sciences researcher.

That’s encouraging news for Florida producers trying to expand their reach, not only in the Sunshine State but nationally, said Joy Rumble, a UF/IFAS assistant professor of agricultural education and communication.

“I was surprised to see that one of the most common ways people reported eating peaches was as a snack,” Rumble said. “I thought that people would be consuming them as part of a meal such as lunch or in a dish such as cobbler or as a topping, like on yogurt. This finding is encouraging for the Florida peach industry because the Florida peach tends to be smaller than those produced elsewhere. There is an opportunity to position and market the Florida peach as the perfect snack.”

UF/IFAS Global honors three faculty members for international work

Topic(s): Agriculture, Announcements, Departments, Extension, IFAS, Research

GAINESVILLE, Fla. — Taking the charge to bring agricultural solutions to countries far and wide, three faculty members with the University of Florida Institute of Food and Agricultural Sciences have done just that. Thus, they were honored at the third annual UF/IFAS Global forum and awards ceremony in February.

Luke Flory, an assistant professor in the agronomy department, received the UF/IFAS Global International Achievement award for his work on reducing the effects of invasive plants around the world. His research has received international recognition, with invitations to speak at universities and organizations in Asia, Canada and Europe, said Rob Gilbert in a nomination letter.

William Giuliano, a professor and UF/IFAS Extension specialist in the department of wildlife, ecology and conservation, was named a UF/IFAS Global International Fellow. Giuliano secured substantial funding for, established, and now directs the Program for Tropical Ecology and Conservation Science and its associated two field stations in Belize. Also, he established a program to conduct research with and train Belizean scientists, said nominator and colleague Eric Hellgren.

GAINESVILLE, Fla. — Even after an insecticide bait weakens Formosan subterranean termites, a neighboring colony will invade the same area and meet the identical lethal fate, new University of Florida Institute of Food and Agricultural Sciences research shows.

The research finding is key for a pest that accounts for much of the $32 billion annual cost caused by subterranean termites worldwide.

“The good news for a homeowner is that as soon as the colony is weakened by baits, the neighboring colony would immediately invade its tunneling system, discover the baits and consume them,” said UF/IFAS entomology professor Nan-Yao Su, co-author of the study. “This always results in the elimination of the invading colony. The results showed that as long as the baits are still present in the bait stations, they will continue to intercept and eliminate incoming colonies.”

UF researcher: Online tool helps make neighborhoods more bird-friendly

GAINESVILLE, Fla. — When it comes to urban planning, sometimes a bird in hand is not worth two in the bush. Researchers with the University of Florida Institute of Food and Agricultural Sciences have created an online tool to help planners strategically conserve forest fragments and tree canopy that will attract more birds and enhance future biodiversity.

The Building for Birds web tool predicts how the distribution of trees and tree patches in a new development will impact resident and migrating bird habitat. Users can test different arrangements to see how they can optimize habitat for different development scenarios.

“When planners do sustainable development, they usually consider factors such as water, energy or transportation. With this tool, they can also consider biodiversity and show good diligence and stewardship,” said Mark Hostetler, professor of wildlife ecology and conservation who developed the web tool with UF graduate student Jan-Michael Archer.

It’s often not possible to include large swaths of undeveloped land in new developments, so the challenge is knowing how to make the most of the habitat that can be retained, Hostetler said.

‘Gloom’ and doom when these insects are on hot, dry red maple trees

Topic(s): Economics, Entomology and Nematology, Environment, Extension, Forestry, Green Living, IFAS, Landscaping, Pests, Research

GAINESVILLE, Fla. — They are known as gloomy scales, and these insects can make a red maple tree’s life downright dreary. This is because the arthropods feed and thrive on them, especially in warm and dry urban landscapes, a University of Florida Institute of Food and Agricultural Sciences researcher says.

Melanaspis tenebricosa, or gloomy scale insects, reproduce more, especially when the trees they live on are under the stress of heat and drought, according to new study led by UF/IFAS entomology assistant professor Adam Dale.

Dale’s new research is important as residents and urban landscapers decide when and where to plant red maple trees, which are native and widely distributed in North America from Florida to Canada and whose canopy helps cool urban areas.

GAINESVILLE, Fla. — As we head into allergy season, you may feel less likely to grab a hanky and sneeze. That’s because new University of Florida Institute of Food and Agricultural Sciences research shows a probiotic combination might help reduce hay fever symptoms, if it’s taken during allergy season.

Many published studies have shown a probiotic’s ability to regulate the body’s immune response to allergies, but not all of the probiotics show a benefit, UF/IFAS researchers say.

“Not all probiotics work for allergies. This one did,” said Jennifer Dennis, a doctoral student in the UF/IFAS food science and human nutrition department and first author on the latest study.

GAINESVILLE, Fla. — How about grapefruit as a dessert or snack? That is how many South Koreans, especially younger ones, view the fruit. Therefore, Florida grapefruit growers may want to expand their shipments to that Asian nation, University of Florida Institute of Food and Agricultural Sciences researchers say.

UF/IFAS researchers are doing a series of surveys for the Florida Department of Citrus, comparing the consumer behavior and market potential for grapefruit in the U.S., Europe and Asia. In the latest study, Yan Heng, a postdoctoral researcher in the UF/IFAS food and resources economics department, conducted an online poll of 992 South Korean female shoppers over 20 years old.

She found South Korea may be a growing market for U.S. grapefruit. Furthermore, South Korean consumers generally consider U.S. products as high quality, so U.S. growers would have a chance to profit by selling with a premium, Heng said.

“We really look at this study and South Korea as information to see if we can increase younger consumers in other countries,” said Lisa House, a UF/IFAS professor of food and resource economics and a study co-author. In addition to eating grapefruit, South Koreans also use grapefruit in beer, tea and ice cream, so marketing opportunities abound.

GAINESVILLE, Fla. — An endangered species of magnolia that only grows in the Florida Panhandle has been named the 2017 plant of the year by the Garden Club of America.

The timing couldn’t be better, says Gary Knox, professor of environmental horticulture with the University of Florida Institute of Food and Agricultural Sciences.

For the last three years, Knox and a team of researchers at the UF/IFAS North Florida Research and Education Center in Quincy, Florida, have been studying the Ashe magnolia to try to figure out why it’s so rare and how it may be conserved.

Ashe magnolias are grown commercially as landscaping plants, and their large flowers and leaves make them popular among gardeners. The white and purple blossoms are the size of dinner plates, and the leaves grow up to two feet long. “This is what we call a ‘charismatic’ plant,” Knox said.

Knox hopes the Garden Club of America’s declaration will help spread awareness about the plight of Ashe magnolias in the wild. According to the Garden Club of America’s web site, “the award is given to an outstanding native plant which is underutilized but possesses superior ornamental and ecological attributes. The goal is to encourage the propagation and planting of these plants in our gardens and the landscape.”
