Pesticide exposure has long been a cause for concern, and with good reason. Studies have shown that all persons, but especially children, pregnant women, farmers, farmworkers, and the elderly, may experience negative health effects from pesticide exposure. These effects may include acute poisoning, cancer, neurological damage, birth defects, reduced sperm count, suppressed immune systems, and reproductive and developmental harm. This book is a comprehensive examination of pesticide use, pesticide harm, and alternatives to harmful pesticides. Levine highlights the role of farming, because a substantial majority—70 percent or more annually—of pesticides are applied in agricultural uses, thereby making their way into the food chain and into the water supply. More than 20 types of pesticides have been detected in U.S. groundwater, and it is believed that nearly 100 have the potential to invade our municipal water systems. Some level of pesticide contamination has been detected in every state, in both urban and agricultural areas. Outside of agriculture, people are exposed to pesticides primarily in the home. Approximately 90 percent of all households in the nation use pesticides, and the number and concentration of these agents indoors has been shown to be greater than outdoors. Given that Americans now spend nearly 90 percent of each day indoors, this is an issue of real concern. In addition to homes, suburban and rural corporate parks are also affected. Schools are another worrisome venue. In too many of our 110,000 school districts, untrained persons are making critical decisions about the use of pesticides in school buildings and on school grounds. No other book currently examines this issue in such breadth and depth.
Herbicides constitute about 60% of the total pesticides consumed globally. In India, the use of herbicides started initially in tea gardens and picked up in the 1970s, when the high-yielding varieties of rice and wheat were introduced. Presently, 67 herbicides are registered in the country for controlling weeds in crops including cereals, pulses, oilseeds, fibre and tuber crops, and also in the non-crop situations. These chemicals are becoming increasingly popular because of their efficiency and relatively low cost compared with manual or mechanical weeding operations. The contribution of herbicide to total pesticide use, which was only 10-15% during the first decade of the 21st century, has now increased to about 25% with an annual growth rate of 15-20%, which is much higher than insecticides and fungicides. Though the application of herbicides is minimizing yield loss to a great extent, their residues in the food chain and surface and groundwater create some environmental nuisance particularly to non-target organisms. Research on pesticide residues in India was started during 1970s, when such chemicals were introduced on a greater scale along with high-yielding variety seeds, irrigation and chemical fertilizers for increasing food production. However, the herbicide residue research was not given much emphasis until 1990s. The Indian Council of Agricultural Research initiated a national level programme known as All India Coordinated Research Project on Weed Management through the NRC-Weed Science as the main centre along with some centers of ICAR Institutes and state agricultural universities. Over the last two decades, adequate information was generated on estimation, degradation and mitigation of herbicide residues, which were documented in annual reports, bulletins, monographs and scientific articles. However, there was no consolidated compilation of all the available information providing a critical analysis of herbicide residues. Accordingly, an effort has been made in the publication to compile the available information on herbicide residues in India. This is the first report of its kind which presents the findings of herbicide residues and their interactions in the biotic and abiotic environment. There are 16 chapters contributed by the leading herbicide residue scientists, each describing the present status of herbicide use, crops and cropping systems, monitoring, degradation and mitigation, followed by conclusions and future lines of work. This book will be useful to the weed scientists in general and herbicide residue chemists in particular, besides the policy makers, students and all those concerned with the agricultural production in the country.
The importance of understanding the metabolism of agrochemicals in
plants has never been greater. In a world where food safety and
environmental concerns are increasing, knowledge of the metabolic
processes within plants and the terminal residues of agrochemicals
in food crops is invaluable. Written by experts in the agrochemical
industry and academia, Metabolism of Agrochemicals in Plants is the
first text to give systematic coverage of this important topic.
This book presents a comprehensive compilation of registration requirements necessary for authorisation of biological control agents (viruses, bacteria, fungi, active substances of natural origin and semiochemicals) in OECD countries. It also reviews data requirements for invertebrate agents (insect, mites and nematodes) and provides proposals for harmonisation of the regulation process and guidelines for completion of application forms. Based on results of the EU REBECA Policy Support Action, which gathered experts from academia, regulation authorities and industry, risks and benefits of the specific agents were reviewed and proposals for a more balanced registration process elaborated, including recommendations for acceleration of the authorisation process and discussions on trade-off effects and policy impacts. All these aspects are covered in detail in this book, which points the way forward for enhanced utilisation of biological control agents. Content Level Research
Insect pests remain one of the main constraints to food and fiber production worldwide despite farmers deploying a range of techniques to protect their crops. Modern pest control is guided by the principles of integrated pest management (IPM) with pest resistant germplasm being an important part of the foundation. Since 1996, when the first genetically modified (GM) insect-resistant maize variety was commercialized in the USA, the area planted to insect-resistant GM varieties has grown dramatically, representing the fastest adoption rate of any agricultural technology in human history. The goal of our book is to provide an overview on the role insect-resistant GM plants play in different crop systems worldwide. We hope that the book will contribute to a more rational debate about the role GM crops can play in IPM for food and fiber production.
"Handbook of Agricultural Entomology" by Helmut van Emden is a landmark publication for students and practitioners of entomology applied to agriculture and horticulture. It can be used as a reference and as a general textbook. The book opens with a general introduction to entomology and includes coverage of the major insects (and mites) that cause harm to crops, livestock and humans. The important beneficial species are also included. Organisms are described in a classification of insect Orders and Families. The emphasis is on morphological characters of major taxonomic divisions, "spot characters" for the recognition of Families, and the life histories, damage symptoms and economic importance of the various pest species. The book is beautifully illustrated in full colour with more than 400 figures showing both the organisms and the damage caused to plants with diagnostic characters indicated by arrows. Coverage is world-wide and includes much material stemming from the vast personal experience of the author.A companion website with additional resources is available at www.wiley.com/go/vanemden/agriculturalentomology
The Sirex woodwasp, Sirex noctilio, is the most important invasive alien insect pest of Pinus plantations in the Southern Hemisphere. It now also threatens pines in North America. This book brings together the worldwide knowledge of researchers from Universities and Government institutions, as well as forest industry practitioners that have worked on the pest. Importantly, it is the first comprehensive treatment of the subject since S. noctilio was discovered outside its native range around 1900. The book covers all aspects of the biology and management of S. noctilio, including aspects of the insects' taxonomy, general life history, host-plant relationships, population dynamics, chemical ecology and symbiosis with the fungus Amylostereum areolatum. The book also contains a comprehensive synthesis of the history and current status of the pest and worldwide efforts to control it, including biological control, silviculture and quarantine.
Plant based Biotechnology has come to represent a means of mitigating the problems of global food security in the twenty first century. Products and processes in agriculture are increasingly becoming linked to science and cutting edge technology, to enable the engineering of what are in effect, designer plants. One of the most successful, non chemical approaches to pest management and disease control, which seeks a solution in terms of using living organisms to regulate the incidence of pests and and pathogens, providing a `natural control' while still maintaining the biological balance with the ecosystem. This volume, describes the various biological agents used to control insect pests of a variety of crops. Readers may also be interested in Volume 1: Crop diseases, Weeds and Nematodes, published in December 2000, ISBN 0-306-46460-8.
The history of biological control of harmful organisms by mites is marked by outstanding achievements with a few premiere natural enemies. Early works concentrated on the use of predatory mites for the control of synanthropic flies, More recently, the focus has been mostly on mites of the family Phytoseiidae for the control of plant feeding mites. This is an important family of acarine predators of plant pest mites, which are effectively used in agriculture worldwide. Besides the vast knowledge in several species in this family, there are as well many opportunities for biological control, represented in an array of organisms and through the improvement of management techniques, which are constantly explored by researchers worldwide. This has resulted in an increasing interest in predatory mite species within the families Stigmaeidae, Ascidae, Laelapidae, Rhodacaroidea, Macrochelidae, Erythraeidae and Cheyletidae, among others. This book will compile important developments with predatory mite species within these families, which are emerging as important tools for integrated pest management. New developments with predatory insects and pathogenic organisms attacking mites will also be a subject of this book. Finally, the potential and gaps in knowledge in biological control of acarine plant pests will be addressed.
Parasitic weeds of the families Cuscutaceae, Orobanchaceae and Scrophulariaceae are considered to be among the major problems facing agriculture in the Tropics and Subtropics. In the last decades, enormous efforts have been made and success achieved by scientists all over the world in gaining a better understanding of their biology and ecology as well as of control methods. However, no substantial reduction of infestation has been achieved in the past and control strategies specific to the different parasites, crops and farming systems must be further developed or adapted and realised among a wider farming population with suitable extension methods. This `Technical Manual' provides up-to-date methodologies for various aspects of research and extension related to parasitic weed species of the genera Striga, Alectra, Orobanche and Cuscuta. It has the intention to support scientists and extension workers of international and national research and extension institutes and universities, who are either new to the subject or plan to apply further techniques they are not yet familiar with.
As 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.
Advances in biochemical techniques are revolutionizing the study of invertebrate ecology. Their application to pest problems is generating detailed information on the population genetics of pests, pest-predator relationships and interactions between pests and their environment.
Plants have developed very sophisticated mechanisms to combat pathogens and pestsusingtheleastamountofreservedorgeneratedenergypossible. Theydothis by activating major defense mechanisms after recognition of the organisms that are considered to be detrimental to their survival; therefore they have been able to exist on Earth longer than any other higher organisms. It has been known for the past century that plants carry genetic information for inherited resistance against many pathogenic organisms including fungi, bacteria, and viruses, and that the relationship between pathogenic organisms and hosts plants are rather complex and in some cases time dependent. This genetic information has been the basis for breeding for resistance that has been employed by plant breeders to develop better-yielding disease resistant varieties, some of which are still being cultivated. Single gene resistance is one type of resistance which has been extensively studied by many research groups all around the world using biotechnological methodologies that have been the subject of many books and journal articles; therefore, it is beyond the scope of this book. This type of resistance is very effective, although it can be overcome by the pressure of pathogenic organisms since it depends on interaction of a single elicitor molecule from the pathogen with a single receptor site in the host.
Hazardous and Trace Materials in Soil and Plants: Sources, Effects and Management explores the latest advancements in reducing, avoiding and eliminating soil contaminants that challenge the health and safety of agricultural plants. With a focus on minimizing the production of those hazardous substances, controlling their distribution and ensuring safe utilization, the book explores each contributing area and provides insights toward improved, sustainable and secure production. This is an excellent reference resource on both current research and future directions from laboratory research to field applications. The combined impacts of climate change and industrialization have led to increased and diversified threats to the health of the soil in which our food crops are grown, as well as in the plants themselves. This dual-hazard scenario is increasingly recognized as a threat to not just the environment, but to global food security as agricultural soils contaminated with pollutants alter plant metabolism, thus resulting in reduced crop quality and production quantity.
The major objective of this book is to highlight the significance of phytonematodes in horticulture. Detailed and latest information on major aspects of phytonematodes associated exclusively with horticultural crops, which is the need of the day, is lacking. Hence, the book has been written mainly with the objective of providing its readers, comprehensive information on the advanced aspects related to phytonematodes associated with horticultural crops. It also provides basic information on plant parasitic nematodes since it is required for a better understanding of advanced topics. Several popular topics, information on which is already available in plenty, have been avoided. Thus, book explicates both the essential fundamental and advanced aspects pertaining to nematodes associated with horticultural crops. The book is conveniently divided into 13 chapters, which cover latest information on the major fundamental and advanced aspects related to phytonematodes including the role of phytonematodes in horticultural industry, phylogenetic and evolutionary concepts in nematodes, major phytonematodes associated with horticultural crops and their diagnostic keys, symptoms caused by phytonematodes and disease diagnosis, nematode population threshold levels, crop loss assessment, nematode diseases of horticultural crops and their management, nematode disease complexes, genetics of nematode parasitism, important nematological techniques and nematodes of quarantine importance. An exclusive chapter on novel methods of nematode management has been included mainly to provide the information on the latest molecules and novel modes of managing nematodes attacking horticultural crops. Routine nematode management aspects, information on which is already available, have not been discussed; instead, this topic reflects the changing scenario of future nematode management. Hence, this book can serve as a friendly guide to meet the requirements of the students, teachers and researchers interested in these 'hidden enemies' of the grower, apart from the research and extension personnel working under Public organizations, officials of State departments of Horticulture, Forestry, field workers and all those concerned and working with plant parasitic nematodes. Appropriate diagrams, convincing tables and suitable graphs/illustrations have been furnished at right places. A complete bibliography has also been included.
In recent decades, repeated use of herbicides in the same field has imposed selection for resistance in species that were formerly susceptible. On the other hand, considerable research in the private and public sectors has been directed towards introducing herbicide tolerance into susceptible crop species. The evolution of herbicide resistance, understanding its mechanisms, characterisation of resistant weed biotypes, development of herbicide-tolerant crops and management of resistant weeds are described throughout the 36 chapters of this book. It has been written by leading researchers based on the contributions made at the International Symposium on Weed and Crop Resistance to Herbicides held at Cordoba, Spain. This book will be a good reference source for research scientists and advanced students.
The economic importance of Tortricidae in agriculture and forestry is great: crops and forests in the temperate climatic zones suffer considerable loss due to this lepidopterous family. This volume covers the entire spectrum from taxonomy, morphology and physiology to chemical and biological control. It will provide an opening to the scientifc literature on Tortricidae for scientists in research institutions, universities and experimental stations. The indices include entries for synonyms referring to the species names used in this volume.
International concern in scientific, industrial, and governmental communities of xenobiotics in foods and in both abiotic and biotic environments over traces has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published research papers and progress reports, and archival documentations. These three international publications are inte grated and scheduled to provide the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamina tion and toxicology. This series is reserved exclusively for the diversified litera ture on "toxic" chemicals in our food, our feeds, our homes, recreational and working surroundings, our domestic animals, our wildlife and ourselves. Tre mendous efforts worldwide have been mobilized to evaluate the nature, pres ence, magnitude, fate, and toxicology of the chemicals loosed upon the earth. Among the sequelae of this broad new emphasis is an undeniable need for an articulated set of authoritative publications, where one can find the latest impor tant world literature produced by these emerging areas of science together with documentation of pertinent ancillary legislation. Research directors and legislative or administrative advisers do not have the time to scan the escalating number of technical publications that may contain articles important to current responsibility. Rather, these individuals need the background provided by detailed reviews and the assurance that the latest infor mation is made available to them, all with minimal literature searching."
This two-volume book presents an up-to-date account of armored
scale insects (Homoptera: Diaspididas), a family of highly
specialized insects, many of which are important agricultural
pests. Being sedentary, colonial and rather cryptic, many species
have invaded new countries with important host plants. This has
made them prime targets for biological control by natural enemies.
In spite of the extensive attention given by research workers to aphids no comprehensive review has been published covering all aspects of aphid biology. A few small books exist on certain aspects of nomenclature, ecology, physiology and natural enemies. Aphid biology is studied by many specialists, all representing their own area of interest, therefore the only way to present this comprehensive review is by the multi-author approach. This three-volume work is compiled in a similar way to the first books in the series World Crop Pests: Spider Mites. The volumes contain contributions by more than 40 authors. In this first volume an account is given on morphology and systematics, anatomy, genetics, life cycles, ways of life, reproduction and polymorphism and interaction with the environment. These topics are followed by an in-depth study of evolution of aphids, especially in connection with the evolution of plants. In addition processes governing the development of population structure and speciation are elicited.
This book aims to assess, evaluate and critically analyze the methods that are currently available for a judicious pest management in durable food. It presents and analyzes a vast amount of methods that are already in use in "real world" industrial applications. After the phase-out of methyl bromide, but also the withdrawal of several insecticides and the continuously updated food safety regulations, there is a significant knowledge gap on the use of risk-reduced, ecologically-compatible control methods that can be used with success against stored-product insect species and related arthropods. The importance of integrated pest management (IPM) is growing, but the concept as practiced for stored products might differ from IPM as historically developed for field crops. This book discusses a wide variety of control strategies used for stored product management and describes some of the IPM components. The editors included chemical and non-chemical methods, as both are essential in IPM. They set the scene for more information regarding emerging issues in stored product protection, such as emerging, alien and invasive species as threats for global food security, as well as the importance of stored-product arthropods for human health. Finally, the analysis of the economics of stored product protection is presented, from theory to practice.
Weeds hold an enigmatic and sometimes-controversial place in agriculture, where they are generally reviled, grudgingly tolerated, and occasionally admired. In most cases, growers make considerable effort to reduce the negative economic impact of weeds because they compete with crops for resources and hinder field operations, thereby affecting crop productivity and quality, and ultimately the sustainability of agriculture. Weed control in production agriculture is commonly achieved through the integration of chemical, biological, and mechanical management methods. Chemicals (herbicides) usually inhibit the growth and establishment of weed plants by interfering with various physiological and biochemical pathways. Biological methods include crop competition, smother crops, rotation crops, and allelopathy, as well as specific insect predators and plant pathogens. Mechanical methods encompass an array of tools from short handled hoes to sophisticated video-guided robotic machines. Integrating these technologies, in order to relieve the negative impacts of weeds on crop production in a way that allows growers to optimize profits and preserve human health and the environment, is the science of weed management.
The development of pesticide resistance in arthropod pests, plant pathogens and weeds can be viewed and studied from two contrasting perspectives. At a fundamental level, resistance provides an almost ideal example of adaptation to withstand severe environmental stress. Population geneticists, biochemists and, most recently, molecular biologists have cast considerable light on the nature of this adaptation in diverse taxonomic groups, and on factors determining its selection and spread within and between populations. Unlike most evolutionary phenomena, however, resistance is also of immediate practical and economic significance. Not only has the number of resistant species continued to increase inexorably, but there has been an alarming increase in the severity and extent of some resistance problems. Cases of organisms resisting virtually all available pesticides are by no means uncommon, and pose a formidable challenge in view of present difficulties in discovering and developing novel chemicals. Although most occurrences of resistance were initially monofactorial, resistance now frequently involves a suite of coexisting mechanisms that protect organisms against the same or different pesticide groups, and may even predispose them to resist new, as yet unused chemicals. |
