Book Synopsis Pesticide Use in U.S. Agriculture by : Jorge Fernandez-Cornejo
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.

Book Synopsis Surface Water Quality by : Ruth Patrick
Download or read book Surface Water Quality written by Ruth Patrick and published by Princeton University Press. This book was released on 2014-07-14 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressing ecologists, legislators, lawyers, and industrialists alike, Ruth Patrick asks what has been accomplished with the millions of dollars spent on upgrading our surface waters. Has the water improved in spite of the fact that the crayfish, snails, and algae are not those that one would expect to find in natural rivers and estuaries? To evaluate the success of environmental laws over the past two decades, the author examines the aquatic life of river systems in the Delaware Valley, Texas, and Georgia--the only areas in the United States where she found enough biological data to determine trends over time. Although tracing the impact of environmental laws is difficult, Patrick found that for these three water systems the results were generally positive. However, if society as a whole wants effective environmental legislation, organizations must take on a more systematic and orderly approach to data gathering. Patrick argues that in monitoring the waters, one must study protozoa, algae, and worms as well as fish, oysters, and shrimp; one must track amounts of metal as well as low concentrations of oxygen. In proposing options for the future, the author predicts that the cost of such monitoring will be higher than present expenditures, but the cost of lax control will be even greater. Originally published in 1992. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
