the residue crop, how the residue was handled (if
at all), and the nutritional status of the previous
crop and subsequent crop all infl uence pathogen
growth and development on the residue (Gilbert
and Woods 2001; Krupinsky and Tanaka 2001).
Interestingly, combine harvesters may contribute
to the dispersal of residue-inhabiting pathogens
by moving pathogen spores from ground level up
into atmospheric wind currents (Friesen et al.,
2001a). Thus, the widespread adoption of reduced
and no-till residue management aids in the
survival, increase, and genetic variability of
potentially damaging residue-inhabiting fungi.
This has caused some shifts and could possibly
cause even greater changes in global wheat
research priorities. Emphasis must be placed on
coupling crop diversifi cation strategies with host
resistance in order to minimize these important
diseases.
