  • COST 817 - Population studies of airborne pathogens on cereals as a means of improving strategies for disease control : Integrated control of cereal mildews and rusts: Towards coordination of research across Europe


In COST Action 817, improved strategies for the integrated use of host resistance genes and fungicides to control pathogens which are spread by wind throughout Europe are developed. The emphasis is put on major pathogens, such as the powdery mildews and rusts of barley and wheat.
To achieve these goals, a detailed knowledge of pathogen populations across Europe is required. Questions that need to be addressed are, among others: the mode of dispersal of the fungal spores; the kind of selection forces influencing the pathogen populations; the way in which these selection forces could be changed through the strategic use of resistance genes and fungicides; the frequency of mutations and sexual recombination in the pathogen and how these mechanisms influence the appearance of new pathotypes; and how molecular markers can be used to improve our understanding of the genetics of host plant resistance and of pathogen virulence, aggressiveness and fungicide sensitivity.
