Available in PDF, EPUB and Kindle. Book excerpt: Healthy seeds and propagules are the basic requirement for producing good grains, fruits and vegetables needed for human survival and perpetuation. Dispersal of microbial plant pathogens via seeds and propagules has assumed more importance than other modes of dispersal, as infected seeds and propagules have the potential to become the primary sources of carrying pathogen inoculum for subsequent crops. Several diseases transmitted through seeds and propagules have been shown to have the potential to damage economies as a result of huge quantitative and qualitative losses in numerous crops. Hence, it is essential to rapidly detect, identify and differentiate the microbial plant pathogens present in seeds and propagules precisely and reliably, using sensitive techniques. Microbial Plant Pathogens: Detection and Management in Seeds and Propagules provides a comprehensive resource on seed-borne and propagule-borne pathogens. Information on the biology of microbial pathogens, including genetic diversity, infection process and survival mechanisms of pathogens and epidemiology of diseases caused by them, are discussed critically and in detail to highlight weak links in the life cycles of the pathogens. Development of effective disease management systems, based on the principles of exclusion and eradication of pathogens and immunization of crop plants to enhance the levels of resistance of cultivars to diseases, has been effective to keep the pathogens at bay. The need for production of disease-free seeds/propagules has been emphasized to prevent the carryover of the inoculum to the next crop or introduction of the pathogens to other locations. Effectiveness of adopting simple cultural practices and development of cultivars resistant to diseases through traditional breeding methods or biotechnological approach have resulted in reducing the pathogen inoculum and disease incidence. Although application of different chemicals may reduce the disease incidence effectively, biological management of crop diseases, employing potential biological control agents have to be preferred to preserve the agroecosystems. Greater efforts have to be made to integrate compatible strategies to enhance the effectiveness of diseases management systems. Protocols appended at the end of relevant chapters form a unique feature of this book to enable the researchers to fine-tune their projects. This 2 volume set provides comprehensive and updated information about the economically-important groups of microbial plant pathogens carried by seed and propagules. Graduate students, researchers and teachers of plant pathology, plant protection, microbiology, plant breeding and genetics, agriculture and horticulture, as well as certification and quarantine personnel will find the information presented in this book useful.

Available in PDF, EPUB and Kindle. Book excerpt: Plant Disease, Volume I: How Disease is Managed is part of a five-volume treatise that discusses the sociology of plant pathology. This volume discusses the great variety of techniques for the diagnosis of plant disease; crop destruction; and theory behind the art of disease management. It also explores topics on how society is constraining the possibilities for management; management of diseases through changing the environment; biological control of plant diseases; weed management through pathogens; and the epidemiologic and genetic concepts of managing host genes. Subsequent chapter presents the management of plant disease with chemicals and some examples of diseases that benefit man and even a few that benefit plants. This book also describes the organization and operation of society-supported disease management activities, as well as important advisory services provided by the industry. This volume concludes with proposals for the education of the practitioners of plant pathology. This work is intended for the advanced researcher in plant pathology to broaden his views, stimulate his thinking, and help to synthesize ideas.

Book excerpt: "This research quarterly, or Iowa State College Journal of Science, has been authorized and established for several distinct purposes as follows : First, to furnish a medium for the prompt publication of the results of research. Experience has shown that many of the technical and scientific journals are at present overcrowded, and it is frequently impossible to secure publication of an article for many months or even a year or more after acceptance. Second, to give opportunity for the publication of preliminary notes. Third, to afford space for the publication of some articles of greater length than can usually be accepted by special journals. Fourth, to give a publication channel to such results of workers on the research staffs as are scarcely long enough to warrant publication as separate bulletins. Fifth, to provide for the prompt publication of certain of the doctoral dissertations. The Journal has come into being as the result of the studies and recommendations of a committee acting for the Iowa State College Chapter of the Society of the Sigma Xi, and for the Osborne Research Club. It is to be trusted that in form, content and scope the publication will reach the high standards set by its proponents."--page [2], Volume 1, number 1 (October 1926).
