Research develops simple 'recipe' for fungus-free horseradish

20.07.2010
In the battle against soil fungi that discolor horseradish roots and can render the entire crop unsellable, University of Illinois researcher Mohammad Babadoost found that subjecting the roots to hot water before planting was most effective in killing the pathogen in propagative root stocks.

The final recipe: submerge in water heated to 47 degrees Centigrade for 20 minutes.

Babadoost was looking for a reliable, non-chemical method to control Verticillium and Fusarium – soil-borne fungi species that cause the internal discoloration of horseradish roots. "The discoloration doesn't affect the taste of the horseradish, but it does affect the color of the processed horseradish sold in glad jars. Consumers expect horseradish to be a light color," said U of I plant pathologist Mohammad Babadoost.

Horseradish producers save root cuttings from their harvest in order to propagate plants in the next season, Babadoost said. "Most of the cuttings are apparently healthy, showing no symptoms, but they are often infected with Verticillium and Fusarium. So, starting horseradish production from pathogen-free cuttings is essential for managing the internal discoloration of roots."

In order to find a treatment, Babadoost experimented with immersing the horseradish root stocks in water at temperatures from 44 to 50 degrees Centigrade for 10, 20 and 30 minutes. Treatments at temperatures lower than 46 degrees Centigrade did not control the pathogens. Treatments at 48 degrees Centigrade or higher affected the germination and vigor of the plant.

"We found that the most effective treatment for control of the pathogens without adverse effects on plant was 47 degrees Centigrade for 20 minutes," Babdoost said.

He said that the beauty of this treatment is that it is a simple, safe, reliable, and cost-effective method. "Hot-water treatment of horseradish roots is simple and can be done using equipment and tools that are readily available to producers and requires no license. It's environmentally safe because no chemicals are used and it's effective," Babadoost said.

Horseradish is an important crop in the Midwest with half of the total commercial horseradish supply of the United States is grown in the Mississippi River Valley near East St. Louis, and horseradish is a high-value cash crop.

Internal discoloration of horseradish roots is the main production problem for horseradish growers. Since the early 1980s, horseradish producers in Illinois have experienced substantial reductions in marketable yield of horseradish as a result of the internal discoloration of roots. Yield losses of up to 100 percent, caused by the internal root discoloration, have frequently occurred in Illinois.

Thermotherapy for Control of Fungal Pathogens in Propagative Rootstocks of Horseradish was published in the April 2010 issue of HortScience. The authors are Anas Eranthodi and Mohammad Babadoost from the University of Illinois and Bernhard Trierweiler from the Max Rubner-Institut in Karlsruhe, Germany.

Funding for the research was provided by the Illinois Department of Agriculture, the North Central Regions, Integrated Pest Management Program, and the American Farmland Trust, US-EPA.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
