Book Description
Oilseed rape is a major arable crop in both Europe and North America. It is attacked by unique complexes of insect pests still largely controlled through the application of chemical insecticides. Crop management systems for the future must combine sustainability with environmental acceptability to satisfy both social and economic demands. This book, in its 17 chapters each led by a world expert, reviews research progress towards developing integrated pest management systems for the crop that enhance conservation biocontrol. This approach is particularly timely because of the development in Europe of insecticide resistance in the pollen beetle, a major pest of the crop. The past decade has seen considerable progress in our knowledge of the parasitoids and predators that contribute to biocontrol, of their distribution patterns, and their behavioural ecology, both within and without the crop. There is potential for natural enemy conservation through modification of within-field crop husbandry practices, as well as, on the landscape scale, through habitat manipulation to encourage vegetational diversity. This book will prove invaluable as a text for researchers, university teachers, graduate scientists, extension workers and growers involved in integrated pest management.

Book Description
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.

Book Description
Agricultural production is related to physical constrains, which may not always be overcomed by technology. However, under the same conditions, it is possible to see well-managed farms consistently making greater profits than similarly structured, neighboring farms. For each abiotical condition, it is well-known there is a difference between the potential and observed yields, which is usually high and often could be reduced through more appropriate management techniques. In this book, we have a selection of agricultural problems encountered in different regions of the world which were addressed using creative solution, offering new approaches for well-known techniques and new tools for old problems.

Book Description
This book deals with the various aspects viz., the disease, geographical distribution, symptoms on different hosts, host range, yield losses, and disease assessment method, while detailed description on pathogen include taxonomic position, phylogeny, variability, sporulation, perpetuation, and spore germination, host-parasite interactions in the form of seed infection, disease cycle, process of infection, and pathogenesis, epidemiology, forecasting, fine structures, biochemical changes, and phytotoxins, host defence mechanism, techniques to study host-parasite relationships, and management practices including cultural, chemical, biological control practices, and deployment of host resistance. The last section deals with gaps in our understanding, and knowledge about management of these diseases, techniques for the diagnosis of disease and offer suggestions for future research priorities. Each aspect has been vividly illustrated with photographs, histograms, figures, tables, electron micrographs for stimulating, effective and easy reading and understanding. We are sure that this comprehensive encyclopaedic treatise on "Alternaria diseases of crucifers” will be of immense use to the researchers, teachers, students and all others who are interested in the diagnosis and management of Alternaria diseases of crucifers world over. Four species of Alternaria are wide spread and most devastating on cruciferous oil yielding crops, vegetables, forage crops, ornamental plants, and numerous weeds all over the world. The damage to the plants is in the form of infections on seed in the soil during sowing, on seedlings during emergence and growth, on stem, leaves, inflorescence, pods and finally to the seed causing yield losses in seed quantity and quality.

Book Description
The book covers the latest development in the biosciences field covering key topics in crop improvement including ‘omic approaches to improving sustainable crop production, advancement in marker technology, strategies in genetic manipulation, crop quality and sustainability and plant microbe interaction detailing on proven technologies to address critical issue for agricultural sustainability which are beneficial for researchers and students. The book also includes aspects of preserving crops after harvest as this is a key factor in promoting sustainable crop quality in terms of addressing waste, choosing the appropriate packaging and moving crops through the food and industrial supply chain. An important strategy to overcome the challenges in providing food for the world population in a sustainable manner is through concerted efforts by crop scientists to embrace new technologies in increasing yield, quality and improving food safety while minimizing adverse environmental impact of the agricultural activities. Most of the proven molecular and genetic technologies in crop science have been tested and verified in model plants such as Arabidopsis and tomato. The technologies, when deployed on various plant species of importance for human nutrition and industrial applications, including cereals, vegetables, fruits, herbs, fibre and oil crops, face many challenges, not only due to their longer life cycle but many other physiological and environmental factors affecting yield and quality of plant products. Furthermore, major impacts on crop production due to catastrophic diseases and global climate change needs urgent and innovative solutions. Therefore a systematic approach, employing various leading-edge technologies that enable the functional elucidation of key pathway genes via ‘omics tools, genome wide association with desired phenotypes and development of cost effective and practicable molecular tools for selection, is vital. The International Conference on Crop Improvement was held to address these and other pressing issues. This volume summarizes the keynote presentations from the meeting and highlights addition discussions that are critical to crop improvement in a challenging time.

Book Description
Disease Resistance in Plants, Second Edition, looks at genetic, epidemiologic, biochemical, and biometric principles for developing new cultivars possessing genetic resistance to diseases. It examines the nature of disease resistance and resistance genes, and it highlights the importance of stabilizing selection, sugar, biotrophy, and necrotrophy to obtain the greatest possible yields. Organized into 17 chapters, this volume begins with an overview of disease resistance in plants and the ways to develop disease-resistant variants. It then discusses unspecific resistance; the resistance gene paradox; susceptibility and resistance within narrow host taxa; phenotypic variation and gene numbers in host plants; discontinuous variation and cytoplasmic inheritance; and experimental difficulties in partitioning variance. The reader is also introduced to epistasis and the structure of virulence in pathogens; the notion of physiological race; how the pathogen adapts to the host; mutation in the pathogen from avirulence to virulence; horizontal and vertical resistance to disease and its epidemiological effects; and the link between protein polymorphism and vertical resistance. In addition, the book discusses genes for susceptibility in the host versus genes for avirulence (or virulence) in the pathogen; sink-induced loss of resistance; high-sugar disease processes and biotrophy; slow rusting of cereal crops; plant resistance against endemic disease; and the accumulation of resistance genes in heterogeneous host populations. This book will be useful to plant pathologists and plant breeders.
