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.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
