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. — 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.”
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.
JAY, Fla. — Do you know where your grits come from? Now, you can buy locally grown grits and cornmeal, and even visit the farm where the corn is grown.
The University of Florida IFAS West Florida Research and Education Center near Jay, Florida, is selling grits and cornmeal from corn grown and ground on its farm. The Gator Grind products are processed at the UF/IFAS West Florida REC and packaged for consumers there.
“We grow the corn, harvest it, put in the grain bin, clean it and grind it in a stone grist mill,” said Wes Wood, center director. “Visitors can come out to the UF/IFAS West Florida REC for one of our field days and see how grits and cornmeal are produced.”
Faculty at the UF/IFAS West Florida REC have been researching corn for decades, Wood said. These scientists conduct trials to determine the best corn varieties for the region, along with optimization of management variables such as soil fertility and pest control, he said.
“We conduct research that helps farmers grow the best crop possible under Florida Panhandle conditions,” Wood said.

GAINESVILLE, Fla. — A University of Florida Institute of Food and Agricultural Sciences entomologist will use a $200,000 grant from the Florida Department of Health to improve tests for the detection of Zika virus.
In 2016, Florida saw 1,272 cases of Zika, which is usually associated with mild symptoms, although severe symptoms may also occur, including Guillain-Barré syndrome and birth defects in babies, according to the U.S. Centers for Disease Control and Prevention. Of those, 256 were locally acquired. So far this year, four more cases have been reported, all travel-related.
Barry Alto, a UF/IFAS assistant professor of medical entomology, said scientists need better diagnostic tools to detect Zika virus to meet challenges to public health. He is working with collaborator Steven Benner at Firebird Biomolecular Sciences LLC to develop methods they hope should take about an hour – far less time than current testing methods. Existing methods require specialized equipment and highly trained personnel, so samples must be transported to specialized laboratory facilities to perform the tests.

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. — A plant always makes for a nice gesture on Valentine’s Day, and University of Florida Institute of Food and Agricultural Sciences researchers are breeding flora that may emit alluring aromas to your sweetheart.
Zhanao Deng, a professor of environmental horticulture at the UF/IFAS Gulf Coast Research and Education Center in Balm, Florida, breeds gerbera daisy cultivars that are resistant to powdery mildew, the most destructive fungal disease for this type of flower.
Deng and his team have released several gerbera daisy cultivars, and some of them performed well in industry trials in Georgia, Ohio and Texas.
The research doesn’t stop there as Deng and his lab are breeding more lines for the future. Meanwhile, they are sequencing the gerbera daisy’s genes, developing DNA-based molecular markers, and trying to find and engineer the gene or genes that control resistance to the powdery mildew.
GAINESVILLE, Fla. — Two UF/IFAS College of Agricultural and Life Sciences alumni, a producer who worked with UF/IFAS Extension and UF/IFAS Research and a contributor to the UF/IFAS School of Forest Resources and Conservation will be inducted into the Florida Agricultural Hall of Fame in February.
Florida Agriculture Commissioner Adam Putnam and the Florida Agricultural Hall of Fame Foundation have announced the four honorees. Each was born and raised on a Florida farm, and each has made outstanding contributions to Florida’s agriculture industry and mentored future leaders in the field. The UF/IFAS-related inductees are:
- W. Bernard Lester, 78, was born in Havana, Florida. Lester graduated from UF CALS with bachelor’s and master’s degrees in agricultural economics, earning the latter degree in 1962. He earned a doctorate in agricultural economics from Texas A&M University.Lester returned to Florida and began his career as a research economist with the Florida Department of Citrus. He was eventually promoted to executive director in 1979. In 1986, he took a position with Alico, Inc. Board of Directors until 2005. During this time, he joined the Gulf Citrus Growers Association and was actively involved in all aspects of the association’s mission.“Bernie Lester has been a tireless advocate on behalf of Florida agriculture for more than four decades,” John Hoblick, president of the Florida Farm Bureau, wrote as part of his letter in support of Lester. “His knowledge of production agriculture and his excellent skills in leadership positions are recognized by anyone works with him…”
