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.

Download or read book Pesticide Use in Vegetable Farming written by Bishnu Prasad Paudel and published by LAP Lambert Academic Publishing. This book was released on 2014-03 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical pesticides play a significant role in combating pest problems in agriculture. Increased production and productivity in agriculture in recent years is largely the result of improved crop varieties as well as enhanced use of pesticides, plant nutrients and irrigation. Besides, positive aspects of pesticides use, their adverse effects on environment and human health have been well documented worldwide. The primary aim of this study was to assess the extent of pesticide usage as well as investigate the knowledge and practice regarding pesticide use and health safety among commercial vegetable growers and pesticide traders of Chitwan district, Nepal. A questionnaire survey with 50 commercial vegetable growers and 12 pesticide traders, formal and informal interviews with different stakeholders (extension agencies, NGOs, vegetable marketing cooperatives) and field observations were carried out to gather information about pesticide use, perception of health effects and pest management practices.
Download or read book Regulating Pesticides in Food written by National Research Council and published by National Academies Press. This book was released on 1987-02-01 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concern about health effects from exposure to pesticides in foods is growing as scientists learn more about the toxic properties of pesticides. The Delaney Clause, a provision of the Food, Drug and Cosmetic Act, prohibits tolerances for any pesticide that causes cancer in test animals or in humans if the pesticide concentrates in processed food or feeds. This volume examines the impacts of the Delaney Clause on agricultural innovation and on the public's dietary exposure to potentially carcinogenic pesticide residues. Four regulatory scenarios are described to illustrate the effects of varying approaches to managing oncogenic pesticide residues in food.

Download or read book No Till Intensive Vegetable Culture written by Bryan O'Hara and published by Chelsea Green Publishing. This book was released on 2020-02-21 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: "No-till farming is the new best practice for preventing soil erosion, building soil biology, and providing growing conditions for vibrant, healthy crops. But for organic vegetable farmers and gardeners-and any farmer who wants to avoid herbicide use-the seemingly insurmountable dilemma with no-till has been how to control weeds without cultivating. In this thorough, practical guide, expert organic farmer Bryan O'Hara provide the answers. O'Hara systemically describes the growing methods he developed and perfected during a multi-year transition of his Connecticut certified organic vegetable farm to a no-till system. O'Hara asserts that this flexible, nature-friendly agricultural methodology is critical to vegetable farming success both economically as well as to maintain the health of the soil and the farm ecosystem. His methodology has proven itself over years of cropping on his home farm, Tobacco Road Farm, as well as other farms in his region, often with stunning results in yields, quality, and profitability. In No-Till Intensive Vegetable Culture, O'Hara delves into the techniques he has experimented with and perfected in his 25 years of farming, including making and using compost, culturing and applying indigenous microorganisms to support soil biology, reduced tillage systems, no-till bed preparation techniques, seeding and transplanting methods, irrigation, use of fertilizers (including foliar feeds), pest and disease management, weed control, season extension, and harvest and storage techniques. O'Hara also explores the spiritual understanding of the nuances of the soil and a farm ecosystem and how that influences practical production decisions such as when to plant, water, and fertilize a crop. O'Hara goal is to pass on his knowledge to those who feel the impulse to make their livelihood in harmony with nature, requiring a relatively small land base of a few acres or less and little capital investment in mechanization. Home gardener and large-scale farmers will also find value in his methods. This manual will provides farmers with an advanced agricultural methodology not available in any other single book on organic vegetable production, a methodology that will allow farmers to continue to adapt to meet future challenges"--

This book was released on 2008-11-01 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Use and Fate of Pesticides in Vegetable-based Agro-ecosystems in Ghana reviews current knowledge on pesticides use in vegetable farming in Ghana and establishes the fate of pesticides in situ in tropical vegetable-based agro-ecosystems as well as their environmental and public health impacts on selected population groups. A field survey showed that vegetable farmers often spray pesticides on prophylactic basis due to lack of information. Although some farmers may be aware of pesticide hazards, adequate protection is hardly taken to minimize risks. About 70% of exposed farmers had a reduction of 30% or more in whole blood acetylcholinesterase activity. About 95% of the farmers interviewed reported symptoms attributable to pesticide exposure. Water, waterbed sediment, and vegetable crops were checked for residues of the pesticides monitored on the farmers’ fields. Residues detected in water and waterbed sediment indicated that these have come from runoff from vegetable fields and that the measured levels were transient. Pesticide residue levels detected in five vegetable crop types (tomato, cabbage, pepper, onion, and eggplants) were correlated to the minimal risk levels (MRLs) set by the United States Agency for Toxic Substances and Disease Registry (ATSDR). Mean intakes of residues by 22- to 75-year old adult farmers were found to be low and did not seem to be associated with health risk. Data on persistent pesticide residues in farmers’ breast milk and blood serum indicated the presence of DDTs, dieldrin, HCB, and HCHs. When daily intakes of DDTs and HCHs to infants through breastfeeding were estimated, some farmers accumulated these compounds in breast milk above the threshold for adverse effects, which raise concerns on children health. Evidence was found for persistence of isomers of endosulfan and its sulfate metabolite in tomato cropped soil and plant tissues. However, the residue concentration in tomato fruits decreased to a level below the Codex MRL given a two-week pre-harvest interval during which no application of the chemical is done. The publication concludes that successful action to reduce the negative impact of pesticides requires sustained, low cost, and well-targeted training interventions. Students and scientists in the fields of environmental chemistry and/or science, farmers, agricultural extension officers and environmental and health regulatory agencies will find this book very useful.

Book excerpt: Since the 1960s, the world's population has more than doubled and agricultural production per person has increased by a third. Yet this growth in production has masked enormous hidden costs arising from widespread pesticide use - massive ecological damage and high incidences of farmer poisoning and chronic health effects. Whereas once the risks involved with pesticide use were judged to be outweighed by the potential benefits, increasingly the external costs of pesticides, to environments and human health, are being seen as unacceptable. In response to this trend, recent years have seen millions of farmers in communities around the world reduce their use of harmful pesticides and develop cheaper and safer alternatives. The Pesticide Detox explores the potential for the phasing-out of hazardous pesticides and the phasing-in of cost effective alternatives already available on the market. This book makes clear that it is time to start the pesticide detox and to move towards a more sustainable agriculture.
Download or read book Plant Soil and Microbes written by Khalid Rehman Hakeem and published by Springer. This book was released on 2016-03-01 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interactions between the plant, soil and microbes are complex in nature. Events may be antagonistic, mutualistic or synergistic, depending upon the types of microorganisms and their association with the plant and soil in question. Multi-trophic tactics can therefore be employed to nourish plants in various habitats and growth conditions. Understanding the mechanisms of these interactions is thus highly desired in order to utilize the knowledge in an ecofriendly and sustainable way. This holistic approach to crop improvement may not only resolve the upcoming food security issues, but also make the environment greener by reducing the chemical inputs. Plant, soil and microbe, Volume 1: Implications in Crop Science, along with the forthcoming Volume 2: Mechanisms and Molecular Interactions, provide detailed accounts of the exquisite and delicate balance between the three critical components of agronomy. Specifically, these two titles focus on the basis of nutrient exchange between the microorganisms and the host plants, the mechanism of disease protection and the recent molecular details emerged from studying this multi-tropic interaction. Together they aim to provide a solid foundation for the students, teachers, and researchers interested in soil microbiology, plant pathology, ecology and agronomy.

Book excerpt: Rodale was founded on the belief that organic gardening is the key to better health both for us and for the planet, and never has this message been more urgent. Now, with Organic Manifesto, Maria Rodale, chairman of Rodale, sheds new light on the state of 21st century farming. She examines the unholy alliances that have formed between the chemical companies that produce fertilizer and genetically altered seeds, the agricultural educational system that is virtually subsidized by those same companies, and the government agencies in thrall to powerful lobbyists, all of which perpetuate dangerous farming practices and deliberate misconceptions about organic farming and foods. Interviews with government officials, doctors, scientists, and farmers from coast to coast bolster her position that chemical-free farming may be the single most effective tool we have to protect our environment and, even more important, our health.
