This book was released on 2019-10-17 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pesticide usage is increasing worldwide and considered among the main factors contributing to the global decline in biodiversity. This Research Topic provides an overview of the state-of-knowledge regarding non-target effects of herbicides, fungicides, insecticides and rodenticides on a variety of ecosystem functions and organisms. Taxa covered in the contributions include algae, amphibians, aquatic fungi, aquatic insects, bats, bumblebees, butterflies, earthworms, enchytraeids, honeybees, plants, rodents and soil microorganisms. The papers also highlight many gaps in our understanding of non-target effects of pesticides and their consequences for biodiversity and functions of various ecosystems. Overall, it became clear that priorities for future work on pesticides and their effects should more focus on investigating or simulating realistic field situations, i.e., multiple applications of pesticides during the growing season including their temporal and spatial interactions with fauna and flora.
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.

Available in PDF, EPUB and Kindle. Book excerpt: The use of pesticide in crop production is inevitable for a hungry world. The majority of world population are hungry, malnourished and hopeless, especially in sub-saharan africa, latin america and asia. For them anything can go for food when it comes to hunger and starvation. The soils in most of these places are impoverished and agricultural output is low. There are many incidences of tropical pests and diseases. All the farmers clamour for improved yield, no matter the means. For them government should not only provide fertilizers and pesticides but highly subsidize or make them free. If increased soil fertility and yield means pouring fertilizer and pesticides to agricultural fields without recourse to rates and soil test, they are ready and free to do so, as little or no regulations are enforced to regulate their use. Nevertheless, if wishes are horses, every developing world farmer will be king. Their wishes are not backed by financial and government power and wherewithal. You see three million farmers competing for 100 bags of fertilizers and 100 liters of pesticide per year with empty pockets. To them the grammar of pesticide in crop production: environmental implications and future challenges are capacity building workshop/seminar grammar where farmers come to wrestle with government and consultant facilitators on breakfast/dinner and envelope money. To them, that is their share of national or international donor cake, because after the workshop there will never be fertilizer or pesticides for their needs. Rather, the facilitators have fulfilled their legal and formal job of pocketing national or foreign donor money into their private bank accounts in the name of bribery and corruption, sometimes including nepotism and all the English in the world.Nevertheless, in developed world who are free from hunger and starvation, in addition to all the agricultural inputs and finance they need for maximum production; they know that all eyes are on them. What they do will make or mare their business. Since the farmers and investors do not want to loose their money as a result of product bycut or seizure and destroy; they operate under the ambient of the law. On the other hand no investor in developed world wants to be idle or engage in unprofitable business. Hence, all hands must be on deck to maintain maximum output and control price at national and international markets. No wonder Meermann et al (1997) lamented that even after 35 years of Rachel Carson publication of "silent spring" with devastating account of the effects of indiscriminate use of agrochemicals, the one sided push for increased output continues. Thus, nature is controlled to this end and reliance on pesticide has not diminished. According to the author, in northern countries, the environmental movement, followed hesitantly by government regulation, has had some impact on stabilizing and perhaps curbing agrochemicals; but in the south, the use of pesticides has increased and chemical companies aggressively expand their markets. However, the search for reliable alternative pest management methods will continue to face farmers, investors and scientists in this century even as pests develop resistance to some available pesticides in midst of transgenic crops. Till that feat food production at extra scale must go on using contaminant level pesticides and avoiding or banning pollutant level pesticides.

Download or read book Health Effects and Pesticide Perception as Determinants of Pesticide Use written by Susmita Dasgupta and published by . This book was released on 2005 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In a recent survey of 820 Boro (winter rice), potato, bean, eggplant, cabbage, sugarcane, and mango farmers in Bangladesh, over 47 percent of farmers were found to be overusing pesticides. With only 4 percent of farmers formally trained in pesticide use or handling, and over 87 percent openly admitting to using little or no protective measures while applying pesticides, overuse is potentially a threatening problem to farmer health as well as the environment. To model pesticide overuse, the authors used a 3-equation, trivariate probit framework, with health effects and misperception of pesticide risk as endogenous dummy variables. Health effects (the first equation) were found to be strictly a function of the amount of pesticides used in production, while misperception of pesticide risk (the second equation) was determined by health impairments from pesticides and the toxicity of chemicals used. Pesticide overuse (the third equation) was significantly determined by variation in income, farm ownership, the toxicity of chemicals used, crop composition, and geographical location. The results highlight the necessity for policymakers to design effective and targeted outreach programs that deal specifically with pesticide risk, safe handling, and averting behavior. Ideally, the approach would be participatory in nature to address key informational gaps, as well as increasing a farmers' awareness retention. The results also point to specific crops and locations experiencing a higher prevalence of overuse-bean and eggplant in general-and overall production in the districts of Chapainawabganj, Chittagong, Comilla, Jessore, Narshingdi, Rajshahi, and Rangpur. Focusing efforts in these crop and geographical areas may have the most measurable effects on pesticide overuse. "--World Bank web site.
Download or read book Pesticide Use in U S Agriculture written by Jorge Fernandez-Cornejo and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pesticide use has changed considerably over the past five decades. Rapid growth characterized the first 20 years, ending in 1981. The total quantity of pesticides applied to the 21 crops analyzed grew from 196 million pounds of pesticide active ingredients in 1960 to 632 million pounds in 1981. Improvements in the types and modes of action of active ingredients applied along with small annual fluctuations resulted in a slight downward trend in pesticide use to 516 million pounds in 2008. These changes were driven by economic factors that determined crop and input prices and were influenced by pest pressures, environmental and weather conditions, crop acreages, agricultural practices (including adoption of genetically engineered crops), access to land-grant extension personnel and crop consultants, the cost-effectiveness of pesticides and other practices in protecting crop yields and quality, technological innovations in pest management systems/practices, and environmental and health regulations. Emerging pest management policy issues include the development of glyphosate-resistant weed populations associated with the large increase in glyphosate use since the late 1990s, the development of Bt-resistant western corn rootworm in some areas, and the arrival of invasive or exotic pest species, such as soybean aphid and soybean rust, which can influence pesticide use patterns and the development of Integrated Pest Management programs.
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 Effects of Pesticide Exposure on Honey Bee Health written by Stephanie Parreira and published by . This book was released on 2016 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Honey bees (Apis mellifera) are responsible for approximately $17 billion in crop production per year in the United States, and are arguably the most important pollinators in the nation. The future of crop pollination and production is threatened by widespread national honey bee colony losses, which have averaged approximately 30% per year over the past decade. Many factors contribute to colony mortality, but the particular impacts of pesticides are still poorly understood. Here, we investigated the impacts of pesticides under conditions that have not been examined in previous research. Our research focused on the effects of an interaction between the neonicotinoid imidacloprid and the fungicide chlorothalonil, and effects of exposure through multiple routes. To understand the potential impacts of pesticide interactions, we exposed whole colonies to imidacloprid, chlorothalonil, or combination of both chemicals through a pollen diet for one month. We found that many of our response variables were unaffected by our treatments, and that outliers influenced the outcome of several analyses. Brood area and prophenoloxidase activity were significantly affected by different treatments when outliers were excluded, although these differences were no longer significant after the multiple comparisons confidence interval adjustment. Similarly, the number of non-pollen foragers returning to the colonies was affected by the interaction between imidacloprid and time, chlorothalonil and time, and both chemicals and time, when outliers were removed. The interactions indicated that seven weeks after the end of the exposure period, both imidacloprid and chlorothalonil reduced the number of non-pollen foragers returning to the colonies. Imidacloprid and chlorothalonil also reduced the number of total foragers returning to the colonies overall. Our results indicate that colonies may be affected by pesticide exposure long after the exposure period, and that bees exposed to pesticides early in life may be detrimentally affected by that exposure at later stages. To determine whether pesticide exposure through multiple routes has a greater effect on bees than single-route exposure, we conducted a laboratory experiment in which we exposed bees to imidacloprid through pollen diet, sugar syrup, or both routes. We found that exposure through sugar syrup increased the midgut proteolytic enzyme activity overall, as well as glucose oxidase activity after four weeks of exposure. Exposure through sugar syrup, as well as exposure through both routes, increased glucose oxidase activity when outliers were included and excluded from the analysis, respectively. Mortality differed significantly between bees exposed to imidacloprid through sugar syrup and those exposed through both matrices, but none of the treatments were significantly different from the control group. We also found that bees in different treatment groups consumed different amounts of sugar syrup and pollen. Our results indicate the importance of conducting laboratory experiments that better reflect field-realistic pesticide exposure by both incorporating effects over a longer period of exposure, and exposure through multiple routes. In summary, our results provide new knowledge and insights on how pesticides impact long-term colony health. Future research must thoroughly examine statistical procedures, outliers, and statistical power, and must also determine interactions between pesticides and pathogens under different conditions, such as different types of pesticide application, honey bee subspecies, nutritional conditions, season, etc. Discerning the variability in results when these conditions vary will provide a fuller understanding of the true impacts of pesticides on colony health.
