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. — 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.”
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.
LIVE OAK, Fla. — Do you want to know how to grow plants without soil? More and more, people want to start a hydroponic farming business. To meet that demand, the University of Florida Institute of Food and Agricultural Sciences Extension will host workshops this month to get you going.
This marks the ninth straight year that Extension faculty at the UF/IFAS Suwanee Valley Agricultural Extension Center will host the workshops. If you are interested, you can attend March 13-14 or March 17-18 at the center, 8202 County Road 417, Live Oak, Florida.
“We had great demand for information coming from growers and potential growers,” said center director and UF/IFAS Extension specialist Bob Hochmuth. “Although many growers are diversifying from traditional farming enterprises, I would say most are not coming from a traditional farming background.”

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.
Redbay ambrosia beetles.
GAINESVILLE, Fla. — Using some pleasant-smelling chemicals, avocado growers may soon be able to repel beetles that inject a potentially deadly fungus into their trees, saving fruit and money, University of Florida Institute of Food and Agricultural Sciences researchers say.
When they’re infected with the laurel wilt fungus, redbay trees – a close cousin to the avocado — emit methyl salicylate to repel redbay ambrosia beetles, the very beetles that gave the trees the fungus in the first place, scientists say in a newly published study.
Florida avocados bring a $100 million-a-year impact to Florida’s economy, UF/IFAS economists say. They grow almost entirely in southern Miami-Dade County, but growers have battled the laurel wilt fungus, which can kill redbay and avocado trees, since it arrived in Georgia in 2003.

GAINESVILLE, Fla. — When you bite into a Florida strawberry for Valentine’s Day or National Strawberry Day on Feb. 27, you savor sweetness and juice. That’s what you’ll find in all varieties bred by University of Florida Institute of Food and Agricultural Sciences researchers. The latest, ‘Florida Beauty,’ (U.S. PPAF) lives up to the UF/IFAS tradition.
As National Strawberry Day approaches on Feb. 27, we can look forward to even better-tasting fruit from UF/IFAS breeder Vance Whitaker as he tries to help Florida’s $360-million-a-year industry.
‘Florida Beauty,’ a collaboration between UF/IFAS and an Australian scientist, is in its early stages, said Whitaker, an associate professor of horticultural sciences at the UF/IFAS Gulf Coast Research and Education Center in Balm, Florida.
GAINESVILLE, Fla. — Nearly a century ago, a group of Polk County citrus growers raised about $14,000 to buy land for a research station. Now, the University of Florida Institute of Food and Agricultural Sciences will celebrate the 100th anniversary of the UF/IFAS Citrus Research and Education Center.
In 1917, UF/IFAS established the Citrus REC. Originally, only a few UF/IFAS scientists worked at the Lake Alfred site, then called the Citrus Experiment Station.
Today, the research center employs 250 people and is also home to the scientific research staff of the Florida Department of Citrus. It is the largest facility in the world devoted to a single commodity, citrus.
“The UF/IFAS Citrus REC has a long, proud tradition of outstanding science and outreach, and the faculty there show every day why the quality of work performed for the next 100 years will be as good or better than the first century at the facility,” said Jack Payne, senior vice president for agriculture and natural resources.

GAINESVILLE, Fla. — The University of Florida Institute of Food and Agricultural Sciences is getting the word out on updates to the federal Worker Protection Standard. Changes take effect January 2017.
The Worker Protection Standard is a regulation originally issued by the U.S. Environmental Protection Agency in 1992, and was most recently revised in 2015 and goes into effect this year. This regulation is primarily intended to reduce the risks of illness or injury to workers and handlers resulting from occupational exposures to pesticides used in the production of agricultural plants on agricultural establishments, said Fred Fishel, professor of agronomy and director of the Pesticide Information Office. This includes farms, forests, nurseries and enclosed space production facilities such as greenhouses, he said.
Workers are generally those who perform hand-labor tasks in pesticide-treated crops, such as harvesting, thinning, and pruning. Handlers are usually those that are in direct contact with pesticides such as mixing, loading, or applying pesticides.
GAINESVILLE, Fla. — University of Florida Institute of Food and Agricultural Sciences economists and other experts will explore economic insights helpful for making informed business and policy decisions at the second annual Florida Agricultural Policy Outlook Conference, organized by the UF/IFAS food and resource economics department.
This year’s topics include the innovation economy, food and nutrition policy, agricultural labor, water quality and management and agricultural production policy and trade.
The conference will be held from 9 a.m. to 4:30 p.m. Feb. 9 at the UF/IFAS Gulf Coast Research and Education Center, 14625 County Road 672, Balm, Florida.
“Agriculture is a vital industry for Florida with interesting opportunities and compelling challenges as we move into the future,” said Spiro Stefanou, chair of the UF/IFAS food and resource economics department. “Our goal is to bring industry experts, researchers, policy and business leaders together to discuss the current and emerging challenges related to Florida as an engine of innovation, policy related to food, nutrition and consumer decision making, water quality and management, agricultural labor and the prospects for our fruit and vegetable industry.”
