Available in PDF, EPUB and Kindle. Book excerpt: The cyst nematodes are a major group of plant pathogens of economic importance in many countries throughout the world. Considerable yield losses have been attributed to cyst nematodes attacking potatoes, sugar beet, soybean and cereals. Because of the protective cyst that is formed, which encloses the eggs, they pose special problems in their control and also in preventing their distribution in soil from infested areas. There has been much research on many aspects of the biology of cyst nematodes and the large number of publications are testimony to their importance as crop pests and of the interest of nematologists in the group. Nevertheless, they continue to pose problems because of the complexity of their phylogeny and taxonomy and there is still much to be investigated on their biology, particularly with those aspects which relate to improving the effectiveness of control. In many respects the biology of the various cyst nematode species is similar, although with variations due to different interactions with hosts and geographical location. Thus, research on any one species has general applicability and this is particularly so with regard to evaluation of control measures, or to the methodology of soil sampling for the assessment of populations prior to growing crops.

Download or read book Biology Control in Agriculture IPM System written by Marjorie Hoy and published by Elsevier. This book was released on 2012-12-02 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological Control in Agricultural IPM Systems covers the proceedings of the 1984 symposium on Biological Control in Agricultural IPM Systems, held in the Citrus Research and Education Center of the University of Florida at Lake Alfred. The symposium summarizes the status and practical use of biological control in agricultural integrated pest management (IPM) systems in the United States. The book is organized into seven parts encompassing 31 chapters that cover the biological control of arthropods, weeds, plant pathogens, and nematodes. After briefly discussing the status and issues of biological control in IPM, the book deals with the basic principles of IPM programs and their related costs, risks, and benefits in biological control. The text also describes the compatibility of plant resistance with biological control of arthropods and the chemical mediated host or prey selection behaviors of entomophagous insects attacking herbivorous insect pests. It explains the development of microbial insecticides; the genetic improvement of insect pathogens; the use of entomogenous nematodes in cryptic and soil habitats; and the techniques for integrating the influences of natural enemies into models of crop/pest systems. The fourth part of the book focuses on the biological control of weeds. The following part considers the general concepts relating to the unique characteristics of plant diseases affecting aerial plant parts. This part also examines the biological control of soil plant pathogens in IPM systems and the use of soilborne viruses, bacteriocins, and hypovirulent strains of fungi as biological control agents. The concluding parts describe the biological control of nematodes and the status and limits to biological control in selected commodity IPM systems, such as citrus, grapes, alfalfa, cotton, and soybean. Entomologists, plant pathologists, weed scientists, nematologists, toxicologists, and economists will find this book invaluable.

Download or read book Ecologically Based Pest Management written by National Research Council and published by National Academies Press. This book was released on 1996-03-21 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Widespread use of broad-spectrum chemical pesticides has revolutionized pest management. But there is growing concern about environmental contamination and human health risksâ€"and continuing frustration over the ability of pests to develop resistance to pesticides. In Ecologically Based Pest Management, an expert committee advocates the sweeping adoption of ecologically based pest management (EBPM) that promotes both agricultural productivity and a balanced ecosystem. This volume offers a vision and strategies for creating a solid, comprehensive knowledge base to support a pest management system that incorporates ecosystem processes supplemented by a continuum of inputsâ€"biological organisms, products, cultivars, and cultural controls. The result will be safe, profitable, and durable pest management strategies. The book evaluates the feasibility of EBPM and examines how best to move beyond optimal examples into the mainstream of agriculture. The committee stresses the need for information, identifies research priorities in the biological as well as socioeconomic realm, and suggests institutional structures for a multidisciplinary research effort. Ecologically Based Pest Management addresses risk assessment, risk management, and public oversight of EBPM. The volume also overviews the history of pest managementâ€"from the use of sulfur compounds in 1000 B.C. to the emergence of transgenic technology. Ecologically Based Pest Management will be vitally important to the agrichemical industry; policymakers, regulators, and scientists in agriculture and forestry; biologists, researchers, and environmental advocates; and interested growers.
