Range and severity of a plant disease increased by global warming

14.08.2007
A paper published in the Royal Society journal Interface on 15th August 2007 highlights recent research that predicts that the range and severity of the plant disease phoma stem canker is increased by global warming.

A research team led by Rothamsted Research has used a weather-based model developed to predict the start and severity of epidemics of phoma stem canker, a disease of oilseed rape and other brassicas that causes losses of $900M worldwide, to investigate the consequences of predicted climate change scenarios.

The team of biologists and mathematicians found that warmer winters significantly advanced the date of stem canker appearance in spring and increased the severity of canker before harvest. They also predicted that epidemics will spread north from England to Scotland, where cankers do not currently occur on oilseed rape.

The research was part of programme of work to reduce reliance on use of pesticides in crop protection. "The phoma stem canker forecast model was developed as a tool to help guide fungicide applications timing by farmers and their advisors. We realised we could extend the use of the model by incorporating climate change scenario data to examine how global warming might impact on future epidemics" explained Dr Neal Evans, a Plant Pathologist at Rothamsted Research.

These results provide a stimulus to develop models to predict effects of climate change on other plant diseases, especially in delicately balanced agricultural or natural ecosystems. Such predictions can be used to guide policy and practice in adapting to effects of climate change on food security and wildlife.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
