The distribution of F. graminearum and soil zones on the prairies, 1994 to 2008

These maps show locations where F. graminearum has been recovered from FDK based on seed surveys done at the Grain Research Laboratory between 1994 and 2008. In 1994, it was mostly restricted to Manitoba and eastern Saskatchewan. By 2002, it was observed in all areas of the prairies. Most positives are in the black soil zone along the northern boundary of the agricultural area of western Canada. This area has the highest average rainfall. However, the northern areas also have lower temperatures than the southern areas and this may serve to moderate disease levels.

F. graminearum one of four species in Canada that cause FHB and is the most important. F. graminearum had been found mostly in black soil zones, which are also areas of highest precipitation.
