Stem Rust of Wheat: From Ancient Enemy to Modern Foe takes a historical look at the significance of major aspects of research on stem rust of wheat in the 20th Century. The exploration of plant pathology's response to stem rust can serve as a case study for assessing how plant pathology developed and functioned in its first full century. Just as the work on Puccinia graminis f. sp. tritici by legendary plant pathology figures, including Anton De Bary and E. C. Stakman, has already advanced the understanding and appreciation of plant diseases, the historical research in this book will provide plant pathologists, plant breeders, mycologists, agronomists, historians, students, teachers and other scientists with insight into the work on stem rust of wheat in the 20th century and its impact on plant pathology's past and future.
