Detection of stem rust race TTKSK (Ug99) from
Uganda in 1998/99 highlighted not only the extremely
high vulnerability of the global wheat crop to stem
rust but also a lack of adequate global systems to
monitor such a threat. Progress in the development
and expansion of the Global Cereal Rust Monitoring
System (GCRMS) is described. The current situation
regarding the Ug99 lineage of races is outlined and
the potential for expansion into important wheat areas
is considered. The GCRMS has successfully tracked
the spread and changes that are occurring within the
Ug99 lineage and is now well positioned to detect
and monitor future changes. The distribution of Ug99
variants possessing combined virulence to Sr31 and
Sr24 is expanding rapidly and future spread outside
of Africa is highly likely. Efficient and effective data
management is now being achieved via the Wheat
Rust Toolbox platform, with an expanding range of
dynamic information products being delivered to endusers.
Application of new technologies may increase
the efficiency of the GCRMS, with mobile devices,
molecular diagnostics and remote sensing all seen to
have potential application in the medium to longterm.
Expansion of the global capacity for race analysis
is seen to be critical and integration of the Global
Rust Reference Centre into the stem rust monitoring
network is seen as a positive development. The current
acute situation with severe epidemics of stripe rust
in many countries indicates a clear need for more
effective global monitoring systems and early warning
for this pathogen. The existing GCRMS for stem rust is
seen as a good foundation for this to occur.
