"It is important that scientists think about and know their history - where they came from, what they have accomplished, and how these may affect the future. Weed scientists, similar to scientists in many technological disciplines, have not sought historical reflection. The technological world asks for results and for progress. Achievement is important not, in general, the road that leads to achievement. What was new yesterday is routine today, and what is described as revolutionary today may be considered antiquated tomorrow. Weed science has been strongly influenced by technology developed by supporting industries, subsequently employed in research and, ultimately, used by farmers and crop growers. The science has focused on results and progress. Scientists have been--and the majority remain--problem solvers whose solutions have evolved as rapidly as have the new weed problems needing solutions. In a more formal sense, weed scientists have been adherents of the instrumental ideology of modern science. That is an analysis of their work, and their orientation reveals the strong emphasis on practical, useful knowledge; on know how. The opposite, and frequently complementary orientation, that has been missing from weed science is an emphasis on contemplative knowledge; that is, knowing why. This book expands on and analyzes how these orientations have affected weed sciences development. Key Features. The first analytical history of weed science to be written. Compares the development of weed science, entomology and plant pathology. Identifies the primary founders of weed science and describes their role"

Insect Pathology is designed for a broad spectrum of readers. Is should be useful to students, lecturers, and researchers requiring information about the principles in insect pathology and the biology of pathogens. It should serve as a resource for specialists to learn about other insect pathogen systems, for generalists to become aware of advances in insect pathology, and for scientists and students, beginning or otherwise, interested in learning about insect pathology.. This book was originally intended to update the 1949 test by E. A. Steinhaus entitled Principles of Insect Pathology. The purpose for this book was twofold: To serve (1) as a text for an insect pathology and/or biological control class and (2) as a comprehensive reference source. Because this book summarizes much of the available information, its usefulness as a textbook for an insect pathology class is apparent. Although the literature citations are extensive, they are far from complete. The literature in insect pathology is voluminous and for the past decade has been expanding at an almost exponential rate. A complete review of the literature is beyond the scope of the book, and an omission of a reference does not preclude its importance. Our citations, however, should serve as a good starting point for those who wish to obtain further information. We have attempted to cover equally all subdisciplines, but shortcomings are unavoidable. For these, we take full responsibility.

Resource Structure of Agriculture: An Economic Analysis focuses on the quantitative economic analysis of the agricultural industry. The book first discusses the theory of resource demand. Topics include decision milieu in agriculture; aggregate demand for an input; and notes on the statistical estimation of the demand function for an input. The text also examines the role of labor in agriculture, including agricultural wages, migration from agriculture, and regional labor supply. The monograph underscores the use of machineries in the agricultural sector. Analysis of post-war demand for power and machinery; early developments in agricultural mechanization; trends in the use of other machinery; and supply conditions for agricultural machinery are discussed. The text also looks at the use of fertilizers and pesticides in the agricultural sector, as well the need to invest in farm buildings. The book examines the demand for resources and supply of agricultural products. Future pattern of resource use and technological change; interactions between demands for different resources; and resource demand and a derived supply elasticity are discussed. The text is a valuable source of data for readers interested in the economic analysis of the agricultural industry.

Understanding the causes and contributing factors leading to outbreaks of food-borne illness associated with contamination of fresh produce continues to be a worldwide challenge for everyone from the growers of fresh-cut produce through the entire production and delivery process. Additionally researchers both at universities and in government agencies are facing an increased challenge to develop means of preventing these foodborne illness occurrences. The premise of this book is that when human pathogen contamination of fresh produce occurs, it is extremely difficult to reduce pathogen levels sufficiently to assure microbiological safety with the currently available technologies. A wiser strategy would be to avoid crop production conditions that result in microbial contamination to start. These critical, problem-oriented chapters have been written by researchers active in the areas of food safety and microbial contamination during production, harvesting, packing and fresh-cut processing of horticultural crops, and were designed to provide methods of contamination avoidance. Coverage includes policy and practices in the US, Mexico and Central America, Europe, and Japan.

Written by a recognized expert and based on his experience in teaching the subject to students with a variety of educational backgrounds, The Science of Grapevines: Anatomy and Physiology is the only book to comprehensively explore the physiology of the grapevine as it occurs around the world.While other books have focused on the vines of specific regions, the globalization of the wine industry and the resulting increase of lands around the world being used for grapevine cultivation have left a gap in information. This book addresses not only the specific issues and concerns of grapevines from regions around the world, but includes important emerging topics such as global climate change, water relations, temperature effect and more. Key Features * Provides global coverage of grapevines, including the regional differences, similarities, challenges and potential changes* Avoids jargon while bringing the reader into this important aspect of the wine industry * Classroom proven by a leading expert in grapevine anatomy
