GAINESVILLE, Fla. — Deep in the soil, underneath your pretty trees, shrubs, plants and vegetables, lurks a fungus lethal to all of them. But University of Florida plant pathologist G. Shad Ali has a tiny silver bullet to kill it.
Ali and a team of researchers with UF’s Institute of Food and Agricultural Sciences, along with the University of Central Florida and the New Jersey Institute of Technology, have found that silver nanoparticles produced with an extract of wormwood, can stop several strains of the fungus phytophthora dead in its tracks.
Phytophthora attacks the leaves and roots of more than 400 plants and tree varieties – everything from tomato plants to oak trees – threatening the Florida’s $15 billion-a-year ornamental horticulture industry.
“The silver nanoparticles are extremely effective in eliminating the fungus in all stages of its life cycle,” Ali said. “In addition, it had no adverse effects on plant growth.”

GAINESVILLE, Fla. — The University of Florida will hold a groundbreaking ceremony today for the Field and Fork Food Pantry. The event will take place at 11 a.m. at Newell Drive, west of the Food Science and Human Nutrition building.
The food pantry will offer members of the UF community healthy, nutritious food free of charge, said Anna Prizzia, campus food systems coordinator. Currently, there are plans to offer fresh produce, non-perishable foods, canned goods and toiletries.
The university will grow food at the UF Community Farm to stock coolers with fresh produce, said Jack Payne, UF’s senior vice president for agriculture and natural resources and leader of the Institute of Food and Agricultural Sciences. “We’ll offer student-led classes in cooking, nutrition and budgeting so that we don’t just slake hunger but promote self-sufficiency,” he said. The pantry is scheduled to open by mid-July.

GAINESVILLE, Fla. — A University of Florida scientist will try to figure out how antibiotic-resistant microorganisms get into cattle. Another will study how to get tomatoes and strawberries to retain their flavors and last longer.
The two vastly different questions will be the focus of separate studies led by UF Institute of Food and Agricultural Sciences faculty members. The National Institute of Food and Agriculture, part of the U.S. Department of Agriculture, has awarded KC Jeong $2.19 million to study the cattle antibiotic question. NIFA also has awarded Kevin Folta and Thomas Colquhoun $500,000 to investigate the strawberry/tomato issue.

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. — Faculty from the University of Florida Institute of Food and Agricultural Sciences produce some of the nation’s tastiest fruits and vegetables.
Researchers at UF’s Plant Innovation Center breed new cultivars and conduct research to boost the taste, smell and appearance of Florida fruits, vegetables and foliage. But the PIC does much more, said UF environmental horticulture Professor David Clark.
“The big thing is this: No other university in the country can pull off what we’ve put together here, so we are novel,” Clark said. “We cover the whole supply chain, from the conception of an idea to the realization of a product.”
UF faculty, administrators and friends gathered Monday at the UF president’s house in Gainesville for Flavors of Florida 2015, a premier event showcasing the edible research products of the UF/IFAS Plant Innovation Center. Industry leaders, donors and guests savored the sensations of tasty tomatoes, flavor-filled fruits and other Sunshine State food and drinks while learning more about the impact that UF/IFAS makes for the agriculture industry. This is the second year the event has been held.
GAINESVILLE, Fla. — Florida’s sweetest event for all things honey bee is set for March 6-7, University of Florida officials announced this week.

The event will be held at the UF Whitney Marine Laboratory in Marineland, Fla. (more …)
GAINESVILLE, Fla. — In recent years, computer technology has begun to help agricultural producers solve dilemmas as old as farming itself — predicting future crop yields, supplies and prices — using sophisticated models that account for weather patterns, soil types, crop management practices and other factors.
It’s known as agricultural systems modeling, and next week, experts in this emerging field will converge on the University of Florida campus to discuss their latest findings at two meetings held by the leading professional organization in the field, the Agricultural Model Intercomparison and Improvement Program, or AgMIP.
The first event, held Feb. 23-25, will focus on ways that models can account for the potential effects of global climate change on pest and disease pressures, said Jim Jones, a distinguished professor emeritus with UF’s Institute of Food and Agricultural Sciences and one of AgMIP’s four co-principal investigators.
The second event, held Feb. 25-28, is an AgMIP global annual workshop and will feature a wide-ranging slate of activities related to agricultural systems modeling, including discussions and presentations on climate change, specific crops, economics and computer technology, he said.
AgMIP’s overall mission, Jones said, is to help scientists and producers understand how agricultural production systems should evolve to ensure food security under variable and changing climate conditions, and how modeling can guide efforts to develop more resilient and sustainable farming systems.
GAINESVILLE, Fla. — Researchers at the University of Florida Institute of Food and Agricultural Sciences have been awarded more than $13.4 million for four studies to help fight citrus greening, the devastating disease that threatens Florida’s $10 billion citrus industry.
The projects are funded through the Specialty Crop Initiative Citrus Disease Research and Education (CDRE) program, which is made available through the Agricultural Act of 2014, also known as the Farm Bill.
The following UF/IFAS research projects were funded:
- $4.6 million to develop an environmentally safe, systematic bacteriacide that can be applied with conventional spray or drench technology to reduce or eliminate pathogens in citrus trees. The goal is to recover fruit production in greening-affected orchards.
- $3.4 million to support ways to provide steam-generated treatments as an immediate, short-term solution to sustain productivity in HLB-affected trees, while reducing adverse effects on crop yield and fruit quality.
- $3.3 million to try to develop an HLB-resistant citrus cultivar.
- $2.9 million target the use of field trials in Florida to develop and effective microbial treatment for citrus plants affected by HLB.
- UF/IFAS is also partnering with the University of California-Davis on a $4.6-million grant that focuses on using new approaches to manage the Asian citrus psyllid, will assess the economic benefits of these approaches and will develop new outreach information.

GAINESVILLE, Fla. – For every degree Celsius that the temperature increases, the world loses 6 percent of its wheat crop, according to a new global study led by a University of Florida scientist. That’s one fourth of the annual global wheat trade, which reached 147 million tons in 2013.
Senthold Asseng, a UF professor of agricultural and biological engineering, used a computer model approach to reach the finding of temperature increases and wheat production.
“We started this with wheat, as wheat is one of the world’s most important food crops,” said Asseng, whose team’s study was published online Dec. 22 in the journal Nature Climate Change. “The simulations with the multi-crop models showed that warming is already slowing yield gains, despite observed yield increases in the past, at a majority of wheat-growing locations across the globe.”
