DOWNLOAD EBOOKWhile many books are available on biological control, this is the only book to detail the application of molecular biology to control of pests and diseases. Each chapter deals with a different pathogen and the application of new molecular biological techniques to the biocontrol of the pathogen. This new reference presents the most comprehensive list of organisms available. Internationally respected experts discuss viruses, bacteria, fungi, nematodes, protozoa, weeds, and insects. Types of control methods are described, and techniques commonly used in molecular biology to identify the etiological agents, diagnose diseases, and develop control methods are reviewed.

DOWNLOAD EBOOKPrevent agricultural loss with natural disease controls that don’t harm the environment—or the people who live in it Despite the worldwide use of chemicals and pesticides to control the devastating effects of plant disease, the international agribusiness market still suffers extensive economic losses each year. Biological Control of Plant Diseases offers natural alternatives to the synthetic fungicides, pesticides, herbicides, and insecticides that have not only failed to stop pests and pathogens, but have raised serious safety and environmental concerns. The world’s leading plant pathologists examine the use of antagonistic microorganisms, inherent resistance, and natural fungicides for plant protection that’s safe, economical, and effective. Biological Control of Plant Diseases presents up-to-date research findings on disease management to provide you with a single-source reference text for developing a sustainable ecosystem that doesn’t depend on harmful and unhealthy agrochemicals. This unique book acts as a catalyst for change, presenting fresh ideas and innovative strategies for finding meaningful solutions to the problems of disease control. Contributors working in the areas of plant protection, microbiology, plant pathology, biotechnology, ecology, and food safety examine topics that include the application of plant tissue culture, competitive root colonization, mycorrhiza in biocontrol, microbial siderophores, antagonism, and genetic regulation. Topics addressed in Biological Control of Plant Diseases include: soil-borne pathogens rhizobacteria organic acids white rot Trichoderma and Agrobacterium phyllosphere manure-based microbes gray mold disease major fungal diseases mycoparasitism microbial chitinases and much more Biological Control of Plant Diseases is an invaluable reference resource for extension scientists and academics working in botany, biology, entomology, ecology, agriculture, horticulture, plant pathology, and the environmental sciences.

DOWNLOAD EBOOKBased on a series of regional meetings on university campuses with officials from the national security community and academic research institutions, this report identifies specific actions that should be taken to maintain a thriving scientific research environment in an era of heightened security concerns. Actions include maintaining the open exchange of scientific information, fostering a productive environment for international scholars in the U.S., reexamining federal definitions of sensitive but unclassified research, and reviewing policies on deemed export controls. The federal government should establish a standing entity, preferably a Science and Security Commission, that would review policies regarding the exchange of information and the participation of foreign-born scientists and students in research.

DOWNLOAD EBOOKSeptoria leaf blotch has been the major disease of wheat in Britain and much of the rest of Europe. It has been reported that the disease causes serious yield losses to range from 31 to 53%. Mycosphaerella graminicola (anamorph: Septoria tritici) is the pathogen which causes Septoria leaf blotch. The disease can be controlled by various methods such as cultural practices, chemical control, using resistant varieties and biological control. In plant pathology, the term biological control leads to the introduction of microbial antagonists or host specific pathogens to suppress diseases and populations of one or more plant pathogens. This study investigated the microbial community on and within wheat leaves which can suppress Septoria leaf blotch by reducing the inoculum level of the causative pathogen M. graminicola. Plate count and DGGE analysis techniques were used to assess the microbial community. The changes in the microbial populations of healthy, senescent and M. graminicola infected i.e. diseased wheat leaves were investigated in vitro on agar plates using plate colony count method. It was found that method was successful in assessing both bacterial and fungal population sizes showing distinct colonies. DGGE is a rapid method which can analyze large number of samples simultaneously. The bands appearing in DGGE profile represent different species present in the microbial population. The DGGE technique was successfully used in this study to assess bacterial community. Bioinformatics tools have also played a vital role in this study for identifying bacterial and fungal species. A total of five bacterial species and five fungal species were identified by bioinformatics tools. The antagonistic abilities of identified bacterial and fungal species were tested against a Septoria isolate in vitro on dual culture PDA plates. Four microorganisms (Fusarium sp., Verticillium sp., Penicillium sp., Sporobolomyces sp. and Microbotryum sp.) in the dual cultures vary in their colony length, width, ratio of length and width and distance bwtween them. But after statistical analysis all the values are insignificant observations of dual culture plates indicated that the microorganisms might inhibit Septoria by competing for space. These microorganisms after testing might be good candidates for further in vivo testing of Septoria inhibition. A thorough knowledge of wheat leaf microbial communities is required for further use of biocontrol in the future.

DOWNLOAD EBOOKThe potential misuse of advances in life sciences research is raising concerns about national security threats. Dual Use Research of Concern in the Life Sciences: Current Issues and Controversies examines the U.S. strategy for reducing biosecurity risks in life sciences research and considers mechanisms that would allow researchers to manage the dissemination of the results of research while mitigating the potential for harm to national security.

DOWNLOAD EBOOKThe biological ways in which diseases of plants, caused by pathogenic microbes can be controlled without the use of chemical pesticides is the subject of this book. The basis of biocontrol (in microbiology, ecology, and plant pathology) is described and many examples of control measures in commercial use or development are given. There is increasing interest in biocontrol from the general public, environmentalists and the major world agrochemical companies, and this easily read text presents recent developments in the subject. The book provides the necessary references and literature citations to allow a more detailed investigation of particular diseases or control systems to be made. This is an important book that will be especially helpful to graduate and undergraduate students in botany, biology, microbiology, plant pathology, agriculture, horticulture, crop science and related courses.

DOWNLOAD EBOOKAs well as examining successful biological control programmes this book analyses why the majority of attempts fail. Off-target and other negative effects of biological control are also dealt with. Chapters contributed by leading international researchers and practitioners in all areas of biological control afford the book a breadth of coverage and depth of analysis not possible with a single author volume. Combined with the use of other experts to review chapters and editorial oversight to ensure thematic integrity of the volume, this book provides the most authoritative analysis of biological control published. Key aspects addressed include how success may be measured, how successful biological control has been to date and how may it be made more successful in the future. With extensive use of contemporary examples, photographs, figures and tables this book will be invaluable to advanced undergraduate and postgraduate students as well as being a `must' for all involved in making biological control successful.
