This pathotype information tool, developed by the University of Aarhus Denmark, displays the changing frequency of Ug99 lineage 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: For simplicity, any non Ug99 lineage pathotypes have been assigned into an “Others” category. In addition, only selective stem rust pathotype data were available for some countries. Hence these graphs do not represent absolute stem rust pathotype frequencies at the country level.
