This pathotype information tool, developed by the University of Aarhus Denmark, displays the changing frequency of yellow rust pathotypes in analysed samples. Selection of any specific combination of country(s) or year(s) is possible. Any new data incorporated into the underlying database will automatically be displayed on the graphs.

NB: Only selective yellow rust pathotype data were available for some countries. Hence these graphs do not represent absolute yellow rust pathotype frequencies at the country level.
