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.

A new UF/IFAS study shows growers can use the Strawberry Advisory System, a web-based tool that Peres helped design, to save up to $1.7 million over 10 years in fungicide use.

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.
“The study will help additional producers to realize the benefits,” Borisova said. “Increased adoption of this system can increase the profitability of the strawberry industry in Florida, and it will help producers to stay competitive in the market.”
Ekaterina Vorotnikova, a doctoral student in food and resource economics, worked on the study to identify how much the web tool could increase profits and yield by reducing spraying for anthracnose and botrytis, two of the crop’s deadliest diseases.
Using a 26-acre farm as her average, Vorotnikova took data collected at UF’s Gulf Coast Research and Education Center from 2006-2012 and put it into a 10-year model. She found that using the web tool increased net profit for strawberries with anthracnose by $1.7 million and $890,000 for those with botrytis. The increased profit stemmed mostly from decreased spraying, Borisova said.
Florida is the nation’s second-leading strawberry producer, behind California. Florida’s crop brings in $366 million annually, according to the state Department of Agriculture and Consumer Services.
“Given that world strawberry production was worth about $4.3 billion in 2013, the development and adoption of expert systems for small fruit production operations can benefit millions of farmers worldwide,” Vorotnikova said.
In 2012 and 2013, a UF/IFAS survey found 96 percent of Florida’s strawberry producers said botrytis attacks their crop. Half said they get anthracnose every three to four years, while 40 percent said they get it every year. Fifty-five percent of respondents said they subscribe to text or e-mail alerts about anthracnose and botrytis risk levels from the system, Borisova said.
Traditionally, strawberry growers sprayed their crop with fungicide weekly. But this was not optimal, said John VanSickle, a UF/IFAS food and resource economics professor and a study co-author.
For example, if conditions do not induce diseases, growers sprayed unnecessarily, wasting chemicals and labor and increasing production costs. Second, if weather worsens unexpectedly, farmers might not be able spray. Third, too much fungicide helps build chemical resistance for the disease, VanSickle said.
The study, written by Vorotnikova, Borisova and VanSickle, was published online last month in the journal Agricultural Systems.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
