This sixth edition of Agrios’ Plant Pathology continues to serve as the ultimate reference in the field. This new edition was edited by Professor Richard P. Oliver in collaboration with Profs. Ralph Hückelhoven, Antonio di Pietro, and Emerson Del Ponte providing expertise across the entire field of plant pathology. Individual chapters have been written by leading experts active in both research and practice from around the world. The book retains the structure of the previous editions but adds a new section on the diseases of major crops, including model species. The book has been substantially updated and expanded. The first section summarizes the interaction between plant and pathogen, from the molecule to the population, and describes how diseases are controlled using agronomy, genetics, and chemistry. The second section reflects the massive changes in the phylogenetics of pathogen groups and describes all aspects of pathogenicity by fungi, oomycetes, viruses, bacteria, nematodes, and parasitic plants. The new third section provides a primer on the diseases of 23 major crops and plant groups. Building on the legacy work of the original author George Agrios, this new edition continues to be the most comprehensive resource and textbook that professionals, faculties, and students can consult for well-organized, essential information. Key Features: • Provides an up-to-date introduction to plant pathology for students, researchers, and extension agents • All chapters have been extensively updated; many are entirely new, with many new figures and diagrams • Emphasizes new data emerging from genomic and genetic research on pathogens and hosts.
