Paperback. Condizione: New. This specially curated collection features four reviews of current and key research on fusarium in cereal crops.The first chapter describes how progress can be built over current agricultural practices in integrated pest management plans. It also addresses the disease cycle of Fusarium head blight, host-pathogen interactions, genetic resistance, the role of mycotoxins, as well as the impact of the disease on yields and loss of crop quality.The second chapter reviews current research on the main fungal diseases affecting barley, as well as what we know about the mechanisms of barley genetic resistance to fungal pathogens. It features detailed discussions on biotrophic foliar diseases such as stem rust and powdery mildew and necrotrophic diseases such as spot blotch and Fusarium head blight.The third chapter reviews control measures for Fusarium head blight, wheat blast and powdery mildew, including the development of resistant cultivars. 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. It also features discussions on the current status of the global fungicide market.…

Paperback. Condizione: New. 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.…
