GAINESVILLE, Fla. — Low-altitude aerial images can detect laurel wilt, a devastating avocado disease, giving growers an early way to identify diseased trees and perhaps help reduce losses to the $100 million-a-year economic impact avocados provide Florida.
Reza Ehsani, an associate professor in agricultural and biological engineering at the UF/IFAS Citrus Research and Education Center in Lake Alfred, used a multi-spectral camera that distinguishes between laurel wilt-affected trees and healthy ones.
Images taken with the camera from a helicopter have significant implications in the management of this important disease and for the commercial avocado industry in Florida. Ehsani said he expects the Federal Aviation Administration to open U.S. airspace for commercial use of unmanned aerial vehicles, which could be equipped with such cameras, by 2017.
“Ultimately, we think that small UAVs, equipped with the right multi-band camera, can be used for scouting for this disease, which could potentially be very cost-effective,” Ehsani said. “The results of this study will enable growers or service companies that use UAVs to detect this disease at an early stage.”
GAINESVILLE, Fla. — University of Florida Institute of Food and Agricultural Sciences faculty have developed a new app for avocado growers that provides an irrigation schedule so users save an estimated 20 to 50 percent on the water they apply to their orchards.
“Weather changes daily, and the app takes into account these changes in the irrigation schedule it provides,” said Kati Migliaccio, an associate professor in agricultural and biological engineering at UF’s Tropical Research and Education Center in Homestead, Florida.

GAINESVILLE, Fla. — Six University of Florida Institute of Food and Agricultural Sciences faculty members, who are trying to solve global issues like food safety and environmental sustainability, have been named as UF Research Foundation Professors for 2015-18.
The recognition goes to faculty who demonstrate a distinguished record of research and a strong research agenda that’s likely to continue to distinguish them in their fields.
“When I look at the breadth of research exemplified by these talented scientists, I am reminded of the complexity and breadth of the IFAS mission, and how fortunate we are to have people of such high caliber working in a university that places such a high value on research and invests so heavily in the research enterprise,” said Doug Archer, UF/IFAS associate dean of research.

GAINESVILLE, Fla. — While a commercially available cure for crop-killing citrus greening remains elusive, University of Florida researchers have developed a tool to help growers combat the insidious disease: an efficient, inexpensive and easy-to-use sensor that can quickly detect whether a tree has been infected.
That early warning could give growers enough lead time to destroy plagued trees and save the rest. (more …)

GAINESVILLE, Fla. — Ever wonder what that plant is in your yard that seems to be taking over? The University of Florida Institute of Food and Agricultural Sciences has a new website designed to help you figure it out.
Researchers with UF/IFAS’ Center for Aquatic and Invasive Plants spent more than a year developing a searchable website and database to help Floridians assess problem— or just plain puzzling —non-native plants. (more …)

GAINESVILLE, Fla. – Human waste may have a new use: sending NASA spacecraft from the moon back to Earth.
Until now, the waste has been collected to burn up on re-entry. What’s more, like so many other things developed for the space program, the process could well turn up on Earth, said Pratap Pullammanappallil, a University of Florida associate professor of agricultural and biological engineering.
“It could be used on campus or around town, or anywhere, to convert waste into fuel,” Pullammanappallil said.
In 2006, NASA began making plans to build an inhabited facility on the moon’s surface between 2019 and 2024. As part of NASA’s moon-base goal, the agency wanted to reduce the weight of spacecraft retuning to Earth. Historically, waste generated during spaceflight would not be used further. NASA stores it in containers until it’s loaded into space cargo vehicles that burn as they pass back through the Earth’s atmosphere. For future long-term missions, though, it would be impractical to bring all the stored waste back to Earth.

GAINESVILLE, Fla. — A consortium of scientists and researchers, led by the University of Florida, has received the prestigious National Institute of Food and Agriculture’s Partnership Award for Multistate Efforts.
The Southeast Climate Extension project is comprised of 19 researchers from half a dozen universities. They engage agricultural producers and help them implement management strategies to protect crops from weather extremes. In addition, they conduct research aimed at reducing climate and weather risks in agriculture and natural resources in Florida, and cooperate with similar programs through the Southeast Climate Consortium.

GAINESVILLE, Fla. – A strawberry monitoring web system that will soon expand to South Carolina is one of many reasons a University of Florida faculty member has won the Lee M. Hutchins Award from the American Phytopathological Society (APS).
The Hutchins award goes to the author or authors of significant published research on basic or applied aspects of diseases of perennial fruit plants, according to the society’s website.
“APS is probably the most prestigious society worldwide in our field of plant pathology, so I am very honored with the nomination and the award,” said Natalia Peres, an associate professor of plant pathology at the Gulf Coast Research and Education Center in Balm.
UF/IFAS Horticultural Sciences chairman Kevin Folta will advise the Pennsylvania House of Representatives’ Agriculture and Rural Affairs Committee Monday, Oct. 6 on the use of transgenic crops, or GMOs.
The committee will have an informational meeting at 9 a.m. with nationally recognized scientists offering presentations about GMO foods. The legislators are gathering information in advance of debate over a bill that would require labeling of genetically engineered food.
GAINESVILLE, Fla. — A University of Florida scientist has moved one step closer to his goal of eliminating 99.9 percent of peanut allergens by removing 80 percent of them in whole peanuts.
Scientists must eliminate peanut allergens below a certain threshold for patients to be safe, said Wade Yang, an assistant professor in food science and human nutrition and member of UF’s Institute of Food and Agricultural Sciences.
If Yang can cut the allergens from 150 milligrams of protein per peanut to below 1.5 milligrams, 95 percent of those with peanut allergies would be safe. It’s challenging to eliminate all peanut allergens, he said, because doing so may risk destroying peanuts’ texture, color, flavor and nutrition. But he said he’s using novel methods like pulsed light to reach an allergen level that will protect most people.
Yang, whose study is published online in this month’s issue of the journal Food and Bioprocess Technology, cautioned that he has done peanut allergen experiments only in a laboratory setting so far. He hopes to eventually conduct clinical trials on animals and humans.
