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. — Growers are bracing for a cold snap tonight that could cost them thousands of dollars in damage. University of Florida Institute of Food and Agricultural Sciences Extension agents and researchers are here to help.
A hard freeze warning is in effect from 2 a.m. to 9 a.m. Thursday, March 16 for many counties in North Florida, according to the National Weather Service in Jacksonville. Temperatures are predicted to be 24 to 27 degrees during these hours.
UF/IFAS Extension specialists are available to give growers advice for the cold spell. Find your county’s UF/IFAS Extension specialists by clicking here. Then click on your county.

MILTON, Fla. — The seasons are changing and it’s time to enjoy the blooming plants across the state. Families are invited to enjoy the Spring Festival of Flowers on April 7 to 9 in Milton. The University of Florida IFAS Milton Campus and the Pensacola State College are sponsoring the free event.
The festival will be held at the UF/IFAS and Pensacola State College Milton Campus, 5988 Hwy. 90, Building 4900, Milton, Florida 32583. The festival hours are 9 a.m. to 5 p.m. on Friday, 9 a.m. to 4 p.m. on Saturday and Sunday.
The festival will feature arts and crafts, plants, flower and herbs, garden supplies, locally grown vegetables, and great food and music. Educational booths will feature UF/IFAS Extension agents answering questions about plants and flowers, eclectic gardening, good bugs and bad bugs, sprinklers and air layering demonstrations, and experts offering advice and hands-on demonstrations on wildlife for your backyard.
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. — Protecting the water Floridians will need for the 15 million additional residents projected to live here 50 years from now means getting today’s 20 million Floridians to conserve water, a University of Florida Institute of Food and Agricultural Sciences researcher says.
Michael Dukes, a UF/IFAS professor of agricultural and biological engineering, said water conservation will be one of many topics at this year’s UF/IFAS Urban Landscape Conference, scheduled for March 16-17 at the Straughn Center, 2142 Shealy Drive, Gainesville.
UF/IFAS experts will share information on landscaping and the issues that go along with it, such as water, horticulture and human behavior, said Dukes, who also works as director of the UF/IFAS Center for Landscape Conservation and Ecology.
GAINESVILLE, Fla. — With spring around the corner, many homeowners are eyeing their crapemyrtle for a good pruning or topping. But pruning may not be necessary, and take too much off and you could harm the tree, said Gary Knox, a professor of environmental horticulture with the University of Florida Institute of Food and Agricultural Sciences.
Traditionally, crapemyrtles were routinely topped, leaving large branch and stem stubs, Knox said. This practice has been called “crape murder” because most people dislike the winter appearance, but many professionals believe the practice impacts crapemyrtle health and structural integrity, he said.
According to Knox, homeowners and land managers should only prune a crapemyrtle for general safety, health of the tree, or if the tree is growing into a house. “Sometimes the tree will grow into a sidewalk, into the side of a building, or obscure the vision of drivers,” Knox said. “So, there is a time to prune the crapemyrtle, but you must do it carefully. Crapemyrtle may need little or no pruning if planted in full sun away from walkways and roads, and in areas with room for plant growth.”

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. — Asian-Americans in three East Coast states, including Florida, yearn for more of their native vegetables, and those crops can be grown in the East, say two University of Florida Institute of Food and Agricultural Sciences researchers.
Gene McAvoy, a UF/IFAS Extension vegetable specialist, and Shouan Zhang, a UF/IFAS plant pathology associate professor, were among a group of 17 researchers from four land-grant universities who surveyed Asian Americans’ preferences in Asian vegetables. Then the researchers tested the crops in various states to see how well they would grow.
There’s a market for locally grown Asian vegetables, researchers say.
In Florida, Asians account for 2.8 percent – or 557,000 — of the state’s 19.8 million people, according to the U.S. Census Bureau. The population of Asian Americans has jumped by 32 percent from 2000 to 2011, according to the census bureau. Asians are expected to make up about 40 million Americans by 2030. On the East Coast alone, there are 5.8 million Asian Americans in 2014, according to the study.

GAINESVILLE, Fla. — Are you concerned about how your water tastes? Do you want to know how much you use, or whether we’ll have enough water for the next generation? A new University of Florida Institute of Food and Agricultural Sciences website links users with UF/IFAS programs on how to preserve and, perhaps improve the quantity and quality of water in Florida.
Click on http://water.ifas.ufl.edu and find educational resources provided by UF/IFAS, said Kati Migliaccio, a UF/IFAS professor of agricultural and biological engineering, who’s among the people who created the site.
“I think our greatest achievement is providing a website for Florida resident to quickly access answers to their questions or solve their problems concerning water,” Migliaccio said.
