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.

New UF/IFAS scientist brings latest technology to battle against invasive species

Topic(s): Agriculture, Announcements, Crops, Departments, IFAS, Invasive Species, Pests

FORT PIERCE, Fla.— Carey Minteer, a research professor with expertise in the use of biological controls to manage invasive plants, has joined the University of Florida Institute of Food and Agricultural Sciences. Florida has the most invasive species in the country, with 28 ports of entry, including seaports, airports and train stations.

Minteer, who is also an expert in geographic information systems, is based at the UF/IFAS Indian River Research and Education Center in Fort Pierce, Florida. She is collaborating with professor James Cuda, UF/IFAS Extension agent Ken Gioeli and other scientists to fight the state’s most noxious weeds, including the Brazilian peppertree, one of Florida’s most widespread invasive plants.

“Dr. Minteer has demonstrated effectiveness in investigating the biological control of invasive weeds in the central U.S.A. and Florida,” said Ronald Cave, UF/IFAS Indian River REC interim director. “Her expertise in biological control is strengthened with her knowledge of sophisticated mapping technology for spatial analysis of large infestations, thereby bringing a new dimension of research capability to the laboratory.”

Kakkar joins UF/IFAS Extension as invasive insect specialist

Topic(s): Agriculture, Announcements, Biocontrols, Crops, Environment, Extension, IFAS, Invasive Species, Pests

FORT PIERCE, Fla. – Garima Kakkar is joining the University of Florida Institute of Food and Agricultural Sciences to help the state fight invasive pests. Kakkar, an expert in invasive insects, is a UF/IFAS Extension St. Lucie County Multicounty Agent.

Kakkar has a diverse range of experience in managing pest insects, and will now serve growers in the world’s premier citrus production region with the latest research findings. Her most recent assignment was working as a postdoctoral research associate for UF/IFAS, along with both UF and the U.S. Department of Agriculture in studies of an invasive whitefly, thrips vectors and a pepper whitefly.

“Dr. Kakkar has been synergistically blending research and practical information to create effective tools for the citrus and fruit crops industry,” said Ed Skvarch, director of UF/IFAS Extension St. Lucie County. “She believes that a channelized production system requires an Extension agent who is more than a liaison between different groups, researchers, growers or industry. Her goal is to develop programs that take research to the fields and industry, for the betterment of our agricultural production systems.”

Since taking her new position, Kakkar has focused on worker protection standards training, and she is organizing soil nutrition programs, developed in conjunction with the UF/IFAS Southwest Florida Research and Education Center in Immokalee, Florida, Skvarch said.

UF/IFAS researcher: Cats, dogs teaming up is best way to keep rodents away

Topic(s): Agriculture, Crops, Environment, Extension, IFAS, Research

GAINESVILLE, Fla. — Cats and dogs may be longtime enemies, but when teamed up, they keep rodents away, a University of Florida Institute of Food and Agricultural Sciences researcher says.

That’s good news for farmers trying to keep rodents from eating their crops and for homeowners trying to keep the nuisances at bay and from spoiling food and potentially spreading disease, said Robert McCleery, a UF/IFAS associate professor of wildlife ecology and conservation.

McCleery, working as part of an international team of researchers found that the combination of dogs and cats reduced rodents from foraging in and around homes and storage buildings. However, dogs or cats by themselves usually won’t help rid your farm or dwelling of pest rodents.

Not all rodents are pests, McCleery said. For example, scientists consider squirrels, beavers and cotton rats helpful to generally be helpful to the environment. In this study, scientists studied the pest rodent, which lives in your house or eats your crops and is usually not native to the area where it is found, he said.

GAINESVILLE, Fla. — Facial recognition software is no longer a thing of the future. But what if similar technologies could one day help farmers identify pests in the field?

Steve Futch, multi-county citrus agent with the University of Florida Institute of Food and Agricultural Sciences Extension, thinks it’s possible. And thanks to the new UF/IFAS Extension Entrepreneurship Program, he and other UF/IFAS Extension faculty now have more of the tools they need to make their ideas a reality.

“One of the missions of UF/IFAS Extension is to connect Floridians with science-based information that will improve their quality of life. Our relationships with our clientele are always evolving, so we are always reassessing and rethinking how we can better serve our audience,” said Nick Place, dean for UF/IFAS Extension. “Entrepreneurial thinking can help us get out of our comfort zone and approach problems in new and creative ways.”

Jan. 17 to 19, UF/IFAS Extension faculty members from around the state heard presentations from several UF entrepreneurship experts, including Elio Chiarelli, entrepreneurship specialist with the UF/IFAS Center for Leadership. As a doctoral student in the UF department of agricultural education and communication, Chiarelli’s research focused on successful entrepreneurship within agriculture and natural resources.

UF/IFAS Citrus REC starts centennial celebration

Topic(s): Agriculture, Announcements, Citrus, Crops, Cultivars, Economics, Extension, IFAS, New Technology, Pests, RECs, Research

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. — Some consumers crave tastier tomatoes than those they buy at the supermarket, so a University of Florida Institute of Food and Agricultural Sciences researcher led a global team of scientists that found chemical combinations for better flavor.

In a study published today in the journal Science, Harry Klee, a UF/IFAS professor of horticultural sciences, led an international research team that included scientists from China, Israel and Spain. Researchers identified chemicals that contribute to tomato flavor.

Step one was to find out which of the hundreds of chemicals in a tomato contribute the most to taste.

Then, Klee said, they asked, “what’s wrong with the modern tomatoes?” They lack sufficient sugars and volatile chemicals critical to better flavor. Those traits have been lost during the past 50 years because breeders have not had the tools to routinely screen for flavor, Klee said.
