Download or read book Soil Microbiology and Sustainable Crop Production written by Geoffrey R. Dixon and published by Springer Science & Business Media. This book was released on 2010-09-08 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils into which crop plants root and from which they obtain essential minerals and water contain huge arrays of microbes. Many have highly beneficial effects on crop growth and productivity, others are pathogens causing diseases and losses to yield and quality, a few microbes offer protection from these pathogenic forms and others have little or no effect. These intimate and often complex inter-relationships are being explored with increasing success providing exciting opportunities for increasing crop yields and quality in sustainable harmony with the populations of beneficial soil microbes and to the detriment of pathogens. This book explores current knowledge for each of these aspects of soil microbiology and indicates where future progress is most likely to aid in increasing crop productivity by means which are environmentally benign and beneficial.
Download or read book Pests of Stored Foodstuffs and their Control written by Dennis S. Hill and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended to serve as an introduction to the pests of stored foodstuffs of all types on a worldwide basis, and as a broad reference text. It is aimed at being complementary to the more detailed and more specific texts that are listed in the References. It does presuppose an adequate basic knowledge of entomology and zoology in the user. The stored products mentioned in the text are commercial products in the widest sense, including all types of plant and animal materials in addition to grain and prepared foodstuffs. Storage is viewed very broadly, from one day on a shelf to several years in a silo, or refrigerated store at -20°C. In many publications the produce surveyed has been restricted to stored grains, because of their obvious importance to human society, and because of the great quantities involved. For many different materials, of both plant and animal origin, there is a shortage of specific information, but it is to be hoped that this situation will gradually be rectified. It should be clearly understood that any reference to animal pests is made in the strict zoological sense, and refers to any members of the Kingdom Animalia. There is a regrettable tendency in some circles to use the term ‘animal’ as being synonymous with ‘mammal’ – a habit to be deplored! There is definite emphasis on animal pests in this text, but micro-organisms are included where relevant.

Download or read book The Fight for Food written by Harold E. Croxall and published by Routledge. This book was released on 2019-07-19 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1984. Without technical Jargon or a mass of confusing statistics, this book describes a wide range of factors influencing agricultural productivity including weather, soil biology and ecology, and human, social, economic and political factors. The ways in which these factors operate and interact with each other to produce the changing circumstances in which farmers take their decisions are discussed. These decisions are the crucial factors in every productivity problem and the authors suggest policy changes which could improve the chances of farmers making the best choices, not only for themselves but for the consumer and the community at large.

Download or read book Plant Pathology V3 written by James G. Horsfall and published by Elsevier. This book was released on 2012-12-02 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Pathology: An Advanced Treatise, Volume III: The Diseased Population Epidemics and Control deals with the epidemics of the diseased population of plants and their forecasting and control. The book highlights the public health implications of plant pathology, giving major consideration to inoculum production, dispersal, and control. This volume is organized into 14 chapters and begins with an overview of populations of inoculum and the consequences of cultivation, emphasizing the inoculum potential. The next chapters focus on the autonomous dispersal of plant pathogens through the soil, seeds, or plant parts; the inoculum dispersal by animals, humans, air, and water; and the factors and processes that trigger an epidemic. The book also introduces the reader to the physical, chemical, and biological aspects of the performance of fungicides on plants and in soil, and then concludes by discussing the genetics of disease resistance and problems associated with plant breeding. This book is a valuable resource for those who are interested in a theoretical treatment of plant pathology and in the broad ecological relationships among organisms, as well as for research workers and advanced students of applied biology.
Download or read book Agricultural and Industrial Applications Environmental Interactions written by Dewayne Torgeson and published by Elsevier. This book was released on 2012-12-02 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fungicides, Volume I: Agricultural and Industrial Applications, Environmental Interactions discusses the application, use, and environmental interactions of fungicides. This book is organized into 15 chapters that cover the commercial development of fungicide and the organism's interaction with the environment. After discussing the history of fungicides, the book presents data on world fungicide usage and how this usage is influenced by epidemiology. It then describes procedures and approaches for commercial fungicide development; practical tests and laboratory techniques for agricultural fungicide toxicity; and significance of fungicide formulation that is determined by a variety of factors, including cost and biological efficiency. The following chapters discuss technological evolution, both in chemical fungicides and in the machinery for their application for soil and seed treatment. The application of foliar and postharvest fungicides and the use of other fungicides as industrial and wood preservatives is also tackled. The last four chapters are concerned with the various interactions between fungicides and the environment which may cause them to be more or less effective. The book will be useful to researchers, advanced students, and professional workers in the fungicide field of study who are concerned with the synthesis and development of better fungicides or their mode of action.
Download or read book Advisory Work in Crop Pest and Disease Management written by Josef Palti and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advisory work, by its very nature, is an intermediary between the re search worker and those who apply the results of his research. The challenge of advisory work is to devise means of and find pathways for transmitting research results to the user, overcome the reluctance of the latter to change, and often combine novel ideas with well-estab lished traditions. Nowhere is this challenge greater than in farming. This is especially true in developing countries, where the gap in the educational level between research workers and farmers may be ex tremely wide. Moreover, village-level advisers are often overburdened with non-professional functions and are not sufficiently backed up by well-trained professional advisers. Thus, in many of these countries there is a serious discrepancy between the knowledge available and that needed and actually applied on the farm. Advisory work in crop protection is no exception, but profits to some extent from two facts: (1) because of the potentially catastrophic nature of pest attack, governments often operate a supervisory crop protection service, the staff of which may be able to dispense some pest control advice; and (2) the staff of pesticide distributors tends to fill, at least in part, the need for advice on how to fight pests and dis eases with chemicals.
Download or read book Plant Disease An Advanced Treatise written by James G. Horsfall and published by Elsevier. This book was released on 2012-12-02 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Disease, Volume I: How Disease is Managed is part of a five-volume treatise that discusses the sociology of plant pathology. This volume discusses the great variety of techniques for the diagnosis of plant disease; crop destruction; and theory behind the art of disease management. It also explores topics on how society is constraining the possibilities for management; management of diseases through changing the environment; biological control of plant diseases; weed management through pathogens; and the epidemiologic and genetic concepts of managing host genes. Subsequent chapter presents the management of plant disease with chemicals and some examples of diseases that benefit man and even a few that benefit plants. This book also describes the organization and operation of society-supported disease management activities, as well as important advisory services provided by the industry. This volume concludes with proposals for the education of the practitioners of plant pathology. This work is intended for the advanced researcher in plant pathology to broaden his views, stimulate his thinking, and help to synthesize ideas.

Download or read book A History of Pesticides written by Graham A Matthews and published by CABI. This book was released on 2018-09-14 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this fascinating book, Graham Matthews takes the reader through the history of the development and use of chemicals for control of pests, weeds, and vectors of disease. Prior to 1900 only a few chemicals had been employed as pesticides but in the early 1940s, as the Second World War raged, the insecticide DDT and the herbicide 2-4-D were developed. These changed everything. Since then, farmers have been using a growing list of insecticides, herbicides and fungicides to protect their crops. Their use has undoubtedly led to significant gains in agricultural production and reduction in disease transmission, but also to major problems: health concerns for both users of pesticides and the general public, the emergence of resistance in pest populations, and environmental problems. The book examines the development of legislation designed to control and restrict the use of pesticides, the emergence of Integrated Pest Management (IPM) and the use of biological control agents as part of policy to protect the environment and encourage the sustainable use of pesticides. Finally, the use of new technologies in pest control are discussed including the use of genetic modification, targeted pesticide application and use of drones, alongside basic requirements for IPM such as crop rotations, close seasons and adoption of plant varieties with resistance to pests and diseases.
