This book features four peer-reviewed reviews on the development of fungicide resistance in agriculture. The first chapter examines how pathogens develop resistance to fungicides and reviews the ways to detect and measure resistance. The chapter also discusses mechanisms of resistance, such as target site mutation and oppression and multi-drug resistance. The second chapter builds on research covered in the first chapter and reviews the development of resistance in cereal pathogens, before presenting and evaluating a variety of anti-resistance strategies. Case studies of how data from field trials have helped illustrate the impact of different control strategies are also included. The third chapter provides a detailed overview of the use of fungicides as an effective and economic tool to control plant diseases. The chapter considers the successful development of fungicides, as well as the challenges facing future fungicide development within a more holistic and sustainable system of food production. The final chapter considers the current status of global wheat production, the impact of crop loss on food security and the emergence of the current regulatory environment surrounding pesticides. The current status of the global fungicide market and some of the major issues in its future longevity is also discussed.
