Fungicide Resistance In Plant Pathogens

This volume offers a comprehensive coverage of the general principles and recent advances in fungicide resistance. It describes the development, mechanisms, monitoring, and management of resistance and covers the most important group of fungicides that have caused resistance on various crops. An historical review of fungicide resistance over the past 40 years sets the scene for up-to-date basic information on mode of action, as well as the genetics, mechanisms, and evolution of resistance. Monitoring for resistance, including the latest developments in molecular diagnostics, moves readers into the practical aspects of resistance management, which is dealt with through a series of case studies outlining fungicide-use strategies on several key crops. The chapters reflect the experience of authors internationally recognised for their significant contributions to fungicide resistance research. The majority of crop diseases are caused by fungal pathogens, and disease control relies heavily on chemically synthesized fungicides. However, modern fungicides often encounter the problem of resistance development in target pathogens. Thus pathogen resistance to fungicides is an important factor that causes loss of yield and quality of crops. It often threatens biosecurity through the decrease of fungicide efficacy in the fields. To manage fungicide resistance successfully will require the promotion of integrated disease management, involving not just chemical fungicides, but also host plant resistance, agronomic factors, and reliable biological control agents where these are available. Well referenced throughout, the book offers a comprehensive account of resistance, which will be useful as a source of material for lecturers and for both industrial and academic scientists involved in fungicide resistance research. It is also a valuable sourcebook for students.

Pathogen resistance to fungicides has become a challenging problem in the managing of crop diseases and has threatened the performance of some highly potent commercial fungicides. Worldwide, resistance to more than one hundred different active ingredients has been reported. This book compiles information on fungicide resistance over the past three decades on the status, development, and processes involved in the build-up of resistance in pathogens to different groups of fungicides, while also suggesting various measures for managing this problem.

"Fungicides are the primary tools used to manage plant diseases, but they are regularly rendered useless by pathogens' ability to develop resistance. The development of resistance to fungicides is arguably the greatest challenge to effectively managing plant diseases. A second obstacle in the development and application of fungicides is the constant change in the chemical landscape, as new chemicals are introduced and others are banned. Fungicide Resistance in North America, Second Edition, is a complete update of the 1988 edition. It describes the current state of fungicide development and management of fungicide resistance in primary pathogens of important agricultural and horticultural crops. Unlike other recently published books on fungicide resistance, this book focuses exclusively on the most significant resistance issues faced by agricultural producers in North America and especially the United States." --Publisher.

This book comprised of three sections that focus various aspects of fungicide usages and its consequences. In the eight-chapter first section, authors discuss implementation of Integrated Plant Disease Management on a wide array of crops grown in different parts of the world: wheat productions in Argentina and in the US; corn, cotton and Eucalyptus productions in Brazil; rice productions in India; peanut productions in the southern US; and pine seedling nurseries in Serbia. The second section is composed of two chapters that explore the possibility of natural products as fungicides. The final section discusses two interesting and important topics on the fungicide-fungus interaction that can influence the implementation of plant disease management practices, fungicide resistance and hormesis.

Plant pathogenic fungi cause devastating damage to crop production worldwide. The growing global population necessitates reduced crop losses to improve food security, and the control of fungal plant pathogens is vital to help maintain food production. Providing a concise and balanced review of fungicides used in crop protection, this book describes the science of fungicide use, selection and resistance within the context of farming situations. Major updates and additions reflecting the emergence of two new classes of fungicides (strobilurins and SDHI) and the increased incidence of fungicide resistance are included in this new edition, which also discusses legislative requirements to reduce fungicide applications, and current trends in fungicide use.
