Preface
In your hands you hold the global sorghum and millet pa-
thology community’s decennial (more or less) summary
of diseases and work in progress. It is not a summary of
all of the work that has ever been done with sorghum and
millet pathology, nor is it a guide to disease identifica-
tion. Instead, it is a considered summary of the current
critical problems and an evaluation of the Community’s
progress since its previous meeting in Harare, Zimbabwe
in 1988. It is the third of these efforts, and both the meet-
ings and the books that have resulted from them have
been important in defining the research agenda for these
crops in the succeeding ten-year interval. The contents of
this volume are based primarily on contributions to the
Third Global Conference on Sorghum and Millet Dis-
eases in Guanajuato, Mexico in September 2000. Indeed,
all but one of the invited talks and all but one of the
working group reports are represented here in some form.
I also solicited some additional chapters that were not
based on any of the presentations to help round out the
volume, and I have included as many contributions as
possible from African scientists who were unable to at-
tend the meeting due to their inability to obtain visas for
travel from the Mexican government.
This volume is somewhat different from its prede-
cessors in that it is not being published by ICRISAT but,
instead, by Iowa State Press, with the goal of expanding
the readership beyond the immediate sorghum and millet
research community. It also is different in that there is FIGURE P-1. Richard A. Frederiksen.
