URBAN TREE planting

GAINESVILLE, Fla. – Florida’s urban tree-planting program works well: 93 percent of the trees planted were still alive up to five years after they were planted, a new University of Florida study shows.

UF researchers attribute the high survival rate to the state’s rules for projects funded as part of its Urban and Community Forestry Grants program.

Run by the Florida Forest Service, the program began in 1990 to encourage cities to plant more trees for such benefits as energy savings, air and water quality and higher property values. For the current fiscal year, program officials approved $307,000 in federal money for 20 Florida cities, counties and nonprofits to help support trees.

Under the program, local entities must match the federal grants. And one year after trees are planted, the Florida Forest Service conducts on-site inspections to be sure trees, which are planted on public properties or rights of way, are alive and healthy.

For the study, scientists with UF’s Institute of Food and Agricultural Sciences in 2010 surveyed 2,354 trees planted at 26 sites, including Orlando, Tampa, Ocala, Lakeland and Vero Beach.

Gulf anglers could be entitled to $585 million after the Deepwater Horizon oil spill, UF/IFAS study says

GAINESVILLE, Fla. — Recreational anglers who normally fish in the Gulf of Mexico lost up to $585 million from lost fishing opportunities in the year of the Deepwater Horizon oil spill and could be entitled to compensation, according to a new University of Florida study.

After a disaster such as an oil spill, trustees — which could include federal, state or tribal authorities – often attempt to secure financial compensation from those responsible.

In the Gulf oil spill, those monies would not go back to individual fishermen, but instead might fund ecosystem improvements or to stock more fish in the Gulf on the fishermen’s behalf, said UF food and resource economics professor Sherry Larkin.

In December 2012, BP agreed to pay $2.3 billion to commercial fishermen, seafood boat captains and crew, seafood vessel owners and oyster leaseholders, but trustees have yet to seek compensation on behalf of recreational fishermen.

Lice can be a real head-scratcher

GAINESVILLE, Fla. – With the start of another school year, a University of Florida expert warns of a head-scratching problem ─ lice.

September is Head Lice Prevention Month, and Rebecca Baldwin, a University of Florida entomology assistant professor, says opportunities abound for head lice to spread from person to person, but parents and children can do plenty to prevent or get rid of the bugs.

Schools check for head lice check when students return in the fall, said Baldwin, a faculty member with UF’s Institute of Food and Agricultural Sciences.

Over the summer, many children attend camp, where they share equipment or have sleepovers at which there is head-to-head contact. Children who have picked up lice at summer camp or from sleepovers will begin exhibiting symptoms of an infestation, which include head- and neck- scratching, nits on the hair shafts and seeing live lice.

UF/IFAS study shows flavor trumps health for blueberry buying

GAINESVILLE, Fla. — Taste trumps health benefits for blueberry buyers, sending a strong message that fruit consumers value flavor most, new University of Florida research shows.

About 61 percent of blueberry consumers buy the fruit for its flavor, while 39 percent do so for psychological reasons, according to two national online surveys. By “psychological,” researchers mean those consumers may buy blueberries because they believe the fruit, which contains antioxidants, provides health benefits.

UF horticultural sciences assistant professor Jim Olmstead will use the data as he breeds new types of blueberries. Olmstead uses traditional breeding methods to create blueberry cultivars that have traits consumers want.

“What we’re trying to determine is: What is the consumer’s perception of the ideal blueberry? What should it look, taste and feel like?” said Olmstead, a faculty member with UF’s Institute of Food and Agricultural Sciences.

UF/IFAS study: Strawberry monitoring system could add $1.7 million over 10 years to some farms

GAINESVILLE, Fla. – A University of Florida-developed web tool can bring growers $1.7 million more in net profits over 10 years than a calendar-based fungicide system because it guides growers to spray their crop at optimal times, a new UF study shows.

The Strawberry Advisory System, devised by an Institute of Food and Agricultural Sciences researcher, takes data such as temperature and leaf wetness and tells growers when to spray fungicide to ward off diseases. Growers can use the system by logging onto www.agroclimate.org/tools/strawberry or use the website to sign up for email or text alerts.

Before the system was developed, strawberry farmers traditionally sprayed weekly during the November-to-March growing season. Spraying more often than is needed wastes money and can lead to fungicide resistance, said Natalia Peres, associate professor in plant pathology, who led the system’s development.

Not all strawberry growers use the system, but this research might persuade them to do so, said Tatiana Borisova, an assistant professor in UF/IFAS food and resource economics department.

UF/IFAS study finds simple solution to monitoring major berry pest

Spotted wing drosophila trap in blueberry bushes1

GAINESVILLE, Fla. – Using a yeast-sugar-water mixture, berry growers can easily keep tabs on a pest that causes millions in damage each year in the U.S., a new University of Florida study shows.

Farmers can conduct a test to determine if the spotted wing drosophila is in their field – and if so, how prevalent. They punch holes near the upper rim of a covered plastic cup and pour in a yeast-sugar-water mix to about 1 inch high in the cup.

The liquid mixture lures the pest, and growers add a drop of dishwashing liquid to thicken the bait and keep the bugs from escaping. Growers check the traps once a week to see how many bugs are in them. Knowing the pest population is the first step to controlling the bug, also known as the drosophila suzukii.

The female insect cuts a slit in the fruit’s skin and lays eggs there. The larvae consume strawberries, blueberries, blackberries, raspberries and other thin-skinned fruit, said Oscar Liburd, a UF entomology and nematology professor.

“The drosophila suzukii is the biggest threat to berry production in the United States,” said Liburd, a faculty member at UF’s Institute of Food and Agricultural Sciences.
