Mites (Acari) for Pest Control

Uri Gerson

Mites (Acari) for Pest Control is an extremely comprehensive publication, covering in depth the 34 acarine families that contain mites useful for the control of pest mites and insects, nematodes and weeds. In addition to providing information on each relevant acarine family, the book includes essential information on the introduction, culture and establishment of acarine biocontrol agents, the effects of the host plants, agrochemicals and environmental factors on mites used in biological control and discusses commercial and economic considerations in their use. Mites are now used in various ways for biological control, with a growing number of species being sold commercially throughout the world. The authors of this landmark publication, who have between them a huge wealth of experience working with mites in biological control programs, have put together a book that will for many years be the standard reference on the subject. The book will be of great value to all those working in crop protection and biological control both in research as well as in commercial operations, including acarologists, entomologists, integrated pest management specialists, agricultural and plant scientists. Libraries in all universities and research establishments where these subjects are studied and taught should all have copies on their shelves.

An authoritative resource on the science and technology of the postharvest sector, this book surveys the body of knowledge with an emphasis on the recent advances in the field.

Induced Resistance for Plant Defence

Dale Walters

Plant diseases worldwide are responsible for billions of dollars worth of crop losses every year. With less agrochemicals being used and less new fungicides coming on the market due to environmental concerns, more effort is now being put into the use of genetic potential of plants for pathogen resistance and the development of induced or acquired resistance as an environmentally safe means of disease control. This comprehensive book examines in depth the development and exploitation of induced resistance. Chapters review current knowledge of the agents that can elicit induced resistance, genomics, signalling cascades, mechanisms of defence to pests and pathogens and molecular tools. Further chapters consider the topical application of inducers for disease control, microbial induction of pathogen resistance, transgenic approaches, pathogen population biology, trade offs associated with induced resistance and integration of induced resistance in crop protection. The book concludes with a consideration of socio-economic drivers determining the use of induced resistance, and the future of induced resistance in crop protection.

Pest and Disease Management Handbook

David Alford V.

Pest and Disease Management Handbook updates the 3rd edition of the Pest and Disease Control Handbook (1989). The structure of this important new book differs in several respects, acknowledging the advances that have been made in integrated crop management and the trends towards the more rational use of pesticides. Fully revised and up-to-date, the book commences with a new introductory chapter covering the principles of pest and disease management. Following chapters, each written by acknowledged experts in the field, cover a group of major temperate northern hemisphere crops. As well as comprehensive details of pest and disease management strategies, each chapter also includes a classification scheme for the cited pests and diseases. This important publication is a vital tool for all those involved in the crop protection / agrochemical industry including business managers, entomologists, agricultural scientists, plant pathologists and those studying and teaching BASIS courses. As an important reference guide for undergraduate and postgraduate students studying agricultural sciences, applied entomology and crop protection, copies of the book should be available on the shelves of all research establishments and universities where these subjects are studied and taught. Pest and Disease Management Handbook is published for the British Crop Protection Council (BCPC) by Blackwell Science. BCPC is a registered charity having the principal objective of promoting the development, use and understanding of effective and sustainable crop protection practice. Dr David V Alford, based in Cambridge, UK, is a member of the BCPC board, with many years' experience working as a government entomologist.

Crop Protection and Sustainable Agriculture

Joan Marsh

The increase in the world population and changes in welfare have led to an enormously expanding demand for food. In the industrialized world, food surpluses rather than shortages are a problem together with adverse environmental impacts from the overuse of chemicals and excessive exploitation of agricultural land. In the developing world, food production cannot keep up with population growth and the gap between demand and supply is growing. This book explores the theme of sustainable agricultural development in the developing world, with a particular focus on crop protection. Includes chapters on the ecology of food production, on sustainable agriculture and crop protection methods, on the economics of food production and more.

Economic Trends in U.S Agriculture and Food Systems Since World War II

Milton Hallberg C.

By examining the fluctuations of the agriculture sector over the last 50 years, Economic Trends in US Agriculture and Food Systems Since World War II is able to give its readers a better glimpse at the future of farming. Author Milton C. Hallberg details the past and potential changes in the number of farms and farm size; farm income and expenses and wealth of farm families; and prices received, prices paid, and variability of prices. Through countless graphics and tables, Hallberg clearly presents his case for continued inoovations and beneficial policies. This book is intended to be a resource for students of agriculture but followers of agricultural history will also find it worthwhile reading.

Government Policy and Farmland Markets

Food Waste to Animal Feed

Michael Westendorf L.

The magnitude of the food-waste disposal problem cannot be understated. Utilisation of food waste is of concern to the food processing industry, consumers, environmentalists, and regulators of handling and disposal systems. Food waste is not consistent in quality, is usually high in moisture content, and is only available locally. This book focuses on the challenges of utilising both wet and/or processed food waste. The regulatory environment relating to food waste, the perspective of the end-users, and practical use as animal feed is also discussed. One of the goals of this publication, other than to give a clear explanation of the subject of food waste and its uses as animal feed, is to stimulate a need for research.
