Book excerpt: A knowledge of the drift characteristics of herbicides and pesticides released from ground and aerial rigs is important in forestry and agricultural applications so that methods for minimizing damage to downwind systems sensitive to these chamicals can be developed. A field experiment was undertaken on the Hanford Reservation in eastern Washington State during 1975 to study techniques for maximizing herbicide applications from a spray airplane on the intended area and minimizing drift. Several early morning experiments comparing drift characteristics of a fixed with a test application for various nozzle systems and herbicide concentrations were made. The results of these experiments have shown that the initial drift and drift deposit components varied by only a factor of two or so, depending on the production of smaller droplets, as various techniques were used to put the herbicides down from the aircraft. Meteorological conditions become increasingly important at greater downwind distances from the source. Furthermore, drift reduction was most effective under conditions of high relative humidities and cool temperatures. At large distances from the source, ground level drift was higher on stable than on unstable days. Comments on methods for improving the experimental design, and applications of studies such as these to forestry will be made.

Download or read book Environmental Chemistry of Herbicides written by Raj Grover and published by CRC Press. This book was released on 1990-11-21 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is rare among those texts on pesticides in that it covers herbicides exclusively. It presents, in one source, information that is typically scattered. This important publication enables the reader to recommend herbicide use more reliably and efficiently. It also highlights environmental issues relevant to herbicide use in agriculture. The book outlines potential areas of further research. This title is of particular value to weed scientists, environmental chemists and engineers, soil scientists, and those responsible for recommending and/or regulating use of herbicides in agriculture. Focuses On: ? Increasing efficiency of herbicides in agriculture ? Decreasing environmental contamination with herbicides ? Dissipation and transformations in water and sediment ? Nature, transport, and fate of airborne residues ? Absorption and transport in plants ? Transformations in biosphere ? Bioaccumulation and food chain accumulation ? Photochemical transformations ? Bound residues ? Predictability and environmental chemistry

Available in PDF, EPUB and Kindle. Book excerpt: Studies of Adjuvants involve many scientific fields from basic research of the chemistry, through investigations into physiological effects and environmental impact, to mixture formulation and field use. These important areas are illustrated in these two volumes, which are contributions from the First International Symposium on Adjuvants for Agrochemicals, held in Brandon, Manitoba on August 5 to 7, 1986. A total of 200 participants from 19 countries met to discuss their common interest in adjuvant science, technology, and application. It is the editors hope that these volumes will stimulate interest in and promote a better understanding of the chemical, physiological, and agronomic aspects of adjuvants as they relate agrochemicals. In addition, the revisedAdjuvants for Agrochemicals: A Selected Bibliography of World Literature in the English Language will be a valuable resource for agricultural researchers and other users. We hope that adjuvant research will lead to even safer, more efficient, and more economical use of chemicals in agriculture and forestry.

Available in PDF, EPUB and Kindle. Book excerpt: Most people know about the presence and health effects of pesticide residues in the water they drink. However, they may not realize the impact of atmospheric transportation and deposition of pesticides on water quality. Scientific studies of pesticides in various atmospheric matrices (air, rain, snow, aerosols, and fog) provide some of the answers.
