Download or read book Herbicide Contamination of Surface Runoff Waters written by John O. Evans and published by . This book was released on 1973 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field and laboratory studies of the movement of herbicides were conducted to determine their potential as contaminants in irrigation return flow. Special emphasis was given to the use of herbicides for vegetation control along ditches, canals and watersheds where high dosages are required to control the excessive growth of grasses and broadleaved weeds. The following herbicides have been studies: substituted urea (diuron), triazines (summitol and atrazine), phenoxyacetic acid (2, 4-D and 2, 4, 5-T) and a substituted pyridine (picloram). The greatest tendency for transport of herbicides in water coming in contact with soils occurs during the initial storms following spray application. If the intensity of the initial precipitation is not sufficient to cause movement across the soil, the danger of herbicide movement is essentially eliminated. The highest concentratoins (ppm) of herbicide observed in surface waters were 1.8, 0.5, 4.2 and 2.7 for diuron, summitol, 2, 4-D, 2, 4, 5-T and picloram, respectively. These levels were observed immediately below treated areas receiving the higher recommended dosages of the herbicides. All herbicide concentrations dropped below the limit of detection within a few hundred meters below the sprayed areas. Presumably, soil filtration, adsorption and dilution are primarily responsible for the loss of herbicides from water.
Download or read book Environmental Chemistry of Herbicides written by Raj Grover and published by CRC Press. This book was released on 1988-03-31 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference book deals with the physico-chemical principles and processes controlling the behavior of herbicides in the soil environ-ment and gives a concise, critical account of techniques associ-ated with each subject matter. It summarizes and tabulates data on herbicides by class or group and provides predictive modeling of their behavior with validation of the models from field data. The in-formation makes the reader fully aware of environmental issues rel-evant to herbicide use in agriculture, and allows more reliable and efficient recommendation of herbicide uses. Summaries and con-clusions suggesting gaps in information and potential areas of fu-ture research are also featured. The text is designed for weed sci-entists, environmental chemists and engineers, soil scientists, and those who are responsible for recommending as well as regulating the use of herbicides in agriculture. Soil Aspects Covered Include: ? Adsorption and bioavailability ? Diffusion and mass flow ? Transport in surface run-off ? Evaporation ? Dissipation ? Transformations

Available in PDF, EPUB and Kindle. Book excerpt: This publication comes with computer software and presents a comprehensive simulation model designed to predict the hydrologic response, including potential for surface and groundwater contamination, of alternative crop-management systems. It simulates crop development and the movement of water, nutrients and pesticides over and through the root zone for a representative unit area of an agricultural field over multiple years. The model allows simulation of a wide spectrum of management practices and scenarios with special features such as the rapid transport of surface-applied chemicals through macropores to deeper depths and the preferential transport of chemicals within the soil matrix via mobile-immobile zones. The transfer of surface-applied chemicals (pesticides in particular) to runoff water is also an important component.
Download or read book The Triazine Herbicides written by Janis Mc Farland Ph.D. and published by Elsevier. This book was released on 2011-08-19 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past 50 years, triazines have made a great impact on agriculture and world hunger by assisting in the development of new farming methods, providing greater farming and land use capabilities, and increasing crop yields. Triazines are registered in over 80 countries and save billions of dollars a year. The Triazine Herbicides is the one book that presents a comprehensive view of the total science and agriculture of these chemicals. With emphasis on how the chemicals are studied and developed, reviewed, and used at the agricultural level this book provides valuable insight into the benefits of triazine herbicides for sustainable agriculture. - Presents previously unpublished information on the discovery, development and marketing of herbicides - Includes a vital section on the origin, use, economics and fate of triazine herbicides - Covers benefits of triazines in corn and sorghum, sugarcane, citrus, fruit and nut crops - Establishes best management practice and environmental benefits of use in conservation tillage
