Download or read book Field Guide for the Biological Control of Weeds in the Northwest written by Rachel Winston and published by Government Printing Office. This book was released on 2017-12-13 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide focuses on the most problematic weeds in eastern North America for which there are at least some biocontrol agents established and/or available. Multiple photos and descriptions of each weed included in this guide emphasize key identification traits and plant ecology. For each weed included in this guide, all biocontrol agents released or currently found in North America are described individually. Photos highlighting key identification features and damage are included. The release history, current status, and recommended use of each biocontrol agent are described in detail. Recommendations and current impact often vary between the US and Canada, therefore, the information is presented separately. Includes international code of best practices for classical biological control of weeds.

Download or read book Horse Pasture Management written by Paul H. Sharpe and published by Academic Press. This book was released on 2018-11-09 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Horse Pasture Management begins with coverage of the structure, function and nutritional value of plants, continuing into identification of pasture plants. Management of soil and plants in a pasture is covered next, followed by horse grazing behavior, feed choices of horses, management of grazing horses, and how to calculate how many horses should be grazing relative to land size. Management of hay and silage are included, since year-round grazing is not possible on many horse farms. A number of chapters deal with interactions of a horse farm with the environment and other living things. As an aid in good pasture management, one chapter explains construction and use of fencing and watering systems. Contributions are rounded out with a chapter explaining how the University of Kentucky helps horse farm managers develop their pasture management programs. - The purpose of the book is to help people provide a better life for horses - Provides the basic principles of pasture management for those involved in equine-related fields and study - Covers a variety of strategies for managing the behavior, grouping, environmental, and feeding needs of grazing horses to ensure high levels of welfare and health - Includes information on environmental best practices, plant and soil assessment, and wildlife concerns - Explains pasture-related diseases and toxic plants to be avoided - Includes links to useful resources and existing extension programs

Download or read book Nontarget Effects of Biological Control written by Peter A. Follett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nontarget Effects of Biological Control is the first book of its kind. The environmental safety of biological control has come under scrutiny due to several areas of concerns: the irreversibility of alien introductions, the prevalence of host switching to innocuous native or beneficial species, dispersal of the biocontrol agent to new habitats away from croplands, and the lack of research on the efficacy and impact of biocontrol attempts. The debate has been strongly polarized between conservationists and biological control practitioners. Nontarget Effects of Biological Control proposes that retrospective analyses of systems in place in which nontarget effects are now documented or suspected provide the necessary information for planning and evaluating future releases to reduce risk. The book presents case histories of past biological control introductions from island and continental ecosystems.

Download or read book Biological Control written by Charles Vincent and published by CABI. This book was released on 2007-08-20 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological control, the management of pests by the use of living organisms, has a long history of application to agriculture around the world. However, the effective use of beneficial organisms is constrained by environmental, legal, and economic restrictions, forcing researchers to adopt increasingly multi-disciplinary techniques in order to deploy successful biological control programs. It is this complex process, including the mindset and the social environment of the researcher as well as the science being pursued, that this book seeks to capture. Chapters reveal the experiences of scientists from the initial search for suitable control agents, to their release into ecosystems and finally to the beneficial outcomes which demonstrate the great success of biological control across diverse agro-ecosystems. Drawing together historical perspectives and approaches used in the development of biological control as well as outlining current debates surrounding terminology and differential techniques, Biological Control: A Global Perspective will be a valuable resource.

Download or read book Biological Control written by George E. Heimpel and published by Cambridge University Press. This book was released on 2017-04-03 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological control is the suppression of populations of pests and weeds by living organisms. These organisms can provide important protection from invasive species and protect our environment by reducing the need for pesticides. However, they also pose possible environmental risks, so biological control interventions must be undertaken with great care. This book enhances our understanding of biological control interactions by combining theory and practical application. Using a combination of historical analyses, theoretical models and case studies, with explicit links to invasion biology, the authors cover biological control of insects, weeds, plant pathogens and vertebrate animals. The book reflects increasing recognition of risks over the past 20 years, and incorporates the latest technological advances and theoretical developments. It is ideal for researchers and students of biological control and invasion biology.
