Available in PDF, EPUB and Kindle. Book excerpt: The need for designers and users of pesticide application equipment to balance the risk of off-target contamination with high product efficacies when using the minimum dose of active ingredient has led to the requirement for more data defining the performance of such equipment. Measurements of the droplet size distribution in sprays from conventional nozzles has shown acceptable levels of consistency between data obtained with different measuring systems enabling such sprays to be classified providing that systems are calibrated with agreed reference nozzles. For sprays with air inclusions different measuring systems have been shown to give comparable and consistent results, and there is now a need to fully integrate such sprays into a revised classification scheme. Temperature of both spray liquid and the surrounding air have been shown to influence droplet size distribution measurements. It is therefore proposed that measurement protocols specify a maximum difference in temperature between the spray liquid and surrounding air of 5°C. For boom sprayers it is not possible to predict accurately the risk of drift from droplet size measurements alone because of the complex detrainment mechanisms involved. It is proposed that standardized wind tunnel procedures be defined that enable the relative risk of drift from different nozzle designs to be quantified. In the future it is likely that more of the information relating to application system performance will be delivered pre-programmed in the units control system or as part of a decision support system.

Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Weed Science provides an introduction to the basic principles of weed science for undergraduate courses. It discusses several aspects of weed biology and control, and traces the history of herbicide development. The book begins with an introduction to weeds, covering their definition, characteristics, harmful aspects, and the cost of weed control. This is followed chapters on weed classification, the uses of weeds, weed biology, weed ecology, allelopathy, the significance of plant competition, weed management and control methods, and biological weed control. Later chapters deal with herbicidesthe most important weed control tools and the ones with the greatest potential for untoward effects. Students of weed science must understand herbicides and the factors governing their use as well as the potential for misuse. These chapters discuss chemical weed control, the properties and uses of herbicides, factors affecting herbicide performance, herbicide application, herbicide formulation, ecological impact of herbicides, pesticide registration and legislation, weed management systems, and the future of weed science.

This book was released on 2000-11-02 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although chemical pesticides safeguard crops and improve farm productivity, they are increasingly feared for their potentially dangerous residues and their effects on ecosystems. The Future Role of Pesticides explores the role of chemical pesticides in the decade ahead and identifies the most promising opportunities for increasing the benefits and reducing the risks of pesticide use. The committee recommends R&D, program, and policy initiatives for federal agriculture authorities and other stakeholders in the public and private sectors. This book presents clear overviews of key factors in chemical pesticide use, including: Advances in genetic engineering not only of pest-resistant crops but also of pests themselves. Problems in pesticide useâ€"concerns about the health of agricultural workers, the ability of pests to develop resistance, issues of public perception, and more. Impending shifts in agricultureâ€"globalization of the economy, biological "invasions" of organisms, rising sensitivity toward cross-border environmental issues, and other trends. With a model and working examples, this book offers guidance on how to assess various pest control strategies available to today's agriculturist.

Download or read book Pesticides in the Diets of Infants and Children written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the pesticides applied to food crops in this country are present in foods and may pose risks to human health. Current regulations are intended to protect the health of the general population by controlling pesticide use. This book explores whether the present regulatory approaches adequately protect infants and children, who may differ from adults in susceptibility and in dietary exposures to pesticide residues. The committee focuses on four major areas: Susceptibility: Are children more susceptible or less susceptible than adults to the effects of dietary exposure to pesticides? Exposure: What foods do infants and children eat, and which pesticides and how much of them are present in those foods? Is the current information on consumption and residues adequate to estimate exposure? Toxicity: Are toxicity tests in laboratory animals adequate to predict toxicity in human infants and children? Do the extent and type of toxicity of some chemicals vary by species and by age? Assessing risk: How is dietary exposure to pesticide residues associated with response? How can laboratory data on lifetime exposures of animals be used to derive meaningful estimates of risk to children? Does risk accumulate more rapidly during the early years of life? This book will be of interest to policymakers, administrators of research in the public and private sectors, toxicologists, pediatricians and other health professionals, and the pesticide industry.

Available in PDF, EPUB and Kindle. Book excerpt: Worldwide concern in scientific, industrial, and governmental com munities over traces of toxic chemicals in foodstuffs and in both abiotic and biotic environments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published progress reports, and archival documentations. These three publications are integrated and scheduled to provide in international communication the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamination and toxicology. Until now there has been no journal or other publication series reserved exclusively for the diversified literature on "toxic" chemicals in our foods, our feeds, our geographical surroundings, our domestic animals, our wild life, and ourselves. Around the world immense efforts and many talents have been mobilized to technical and other evaluations of natures, locales, magnitudes, fates, and toxicology of the persisting residues of these chemicals loosed upon the world. Among the sequelae of this broad new emphasis has been an inescapable need for an articulated set of authorita tive publications where one could expect to find the latest important world literature produced by this emerging area of science together with documentation of pertinent ancillary legislation.
Download or read book Agrochemical Environmental Fate State of the Art written by Marguerite L. Leng and published by CRC Press. This book was released on 1995-04-28 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accurate risk assessment is critical to pesticide regulation. This authoritative reference provides an exhaustive evaluation of current agrochemical environmental fate studies, a critical review of current EPA pesticide assessment guidelines, and a wide variety of environmental simulation models. Divided into four sections, this well-organized book provides a wealth of data and information vital to anyone involved in environmental exposure assessment, groundwater, surface water, and water contamination, pesticide regulation, and environmental simulation modeling. At your fingertips, you will have the latest information on the development of meaningful environmental fate data and how this information will result in accurate assessment of potential environmental and human hazards. The inadequacy of current regulatory guidelines and the resulting nonscientific assessment of agrochemical environmental fate are discussed in detail. A wide variety of environmental fate studies are included to demonstrate the current use of data to assess environmental fate and potential hazards associated with agrochemical use. Finally, ten chapters discuss the use of computer models that have been developed for analyzing and integrating data from a variety of environmental fate studies on agrochemicals used under various field conditions.
