In the last 25 years, attention to the septoria diseases of wheat has intensified. The two pathogens of the septoria group that have the greatest impact on global wheat production are Septoria tritici and Septoria noorum. Annual yield losses worldwide due to both diseases are estimated at about 9 million metric tons. Breeding for resistance has obtained a preeminent place in a number of research and crop improvement programs worldwide. In this introduction, emphasis is placed on summarizing the more pertinent scientific reports for managing the two major septoria pathogens. Research data are interpreted into concepts and procedures. Topics include the biology of the fungi, infection process, collection and handling of infected material, isolation and maintenance of the fungi, inoculum production, artificial inoculation, disease assessment, epidemiology, pathogen specialization, breeding for resistance, and means of cultural and chemical control. Each treatment of a topic or group of alternative methods is followed by the recommendation of one or more preferred techniques or approaches. This information is intended for wheat scientists in developed and developing countries who are unfamiliar with these diseases. [AS]
