Plant disease management remains an important component of plant pathology and is more complex today than ever before including new innovation in diagnostic kits, the discovery of new modes of action of chemicals with low environmental impact, biological control agents with reliable and persistent activity, as well as the development of new plant varieties with durable disease resistance. This book is a collection of invited lectures given at the 9th International Congress of Plant Pathology (ICPP 2008), held in Torino, August 24-29, 2008 and is part of a series of volumes on Plant Pathology in the 21st Century. It focuses on new developments of disease management and provides an updated overview of the state of the art given by world experts in the different fields of disease management. The different chapters deal with basic aspects of disease management, mechanisms of action of biological control agents, innovation in fungicide application, exploitation of natural compounds and resistance strategies. Moreover, the management of soil-borne diseases and disease management in organic farming are covered.

Pathogen resistance to fungicides has become a challenging problem in the management of crop disease. It has threatened the performance of some highly potent commercial fungicides, resulting in resistance to more than one hundred different active ingredients reported from around the world. This book compiles information on fungicide resistance over the past three decades, beginning with the history of resistance development, then exploring the status, detection and management of resistance in pathogens to different groups of fungicides with diverse case studies from countries including France, India, Italy, Japan and the US. It also discusses the genetics of resistance and the problem of multidrug resistance, before concluding with an overview of the work and initiatives of the Fungicide Resistance Action Committee for managing this problem.An essential resource for researchers and students of plant pathology and mycology, this book is also a useful collection of the present status and future projections of fungicide resistance for extensions workers and pesticide industry personnel.
