This retrospective review deals with the sequence of events and research progress on control of stripe rust of wheat and barley in North America. From the discovery of stripe rust in 1915, it documents the early years of stripe rust research, the 20-year hiatus when stripe rust was not considered important and research was almost nonexistent, the short period in the 1950s when stripe rust became prevalent in the central United States, and the severe epidemics in the West in the 1960s and the associated revival and expansion of research. Finally, it covers 1968 to 2001 when the earlier information was consolidated and combined with results of new research to enable prediction and control of stripe rust, especially in the West.
