Herbicides are of great importance in weed management and are one of the most widely used pesticide groups for weed control across the globe. Concerns around the residual effects of these intensively used chemicals are equally widespread. Offering a new direction for research that focuses on herbicide behavior and its impacts on the environment, this book covers the use of radioisotopes in weed research and the detoxification of herbicides. Applying technological advances in radiation detection, Radioisotopes in Weed Research explains how isotopic techniques can be used to identify degradation products and trace the fate of herbicides applied to crop plants. This book provides essential information on the historical use and recent advances of radioisotopes in weed research. It demonstrates the potential these methods offer the field of weed science in gaining a better understanding of the behavior of herbicides in plants and soil and working to ensure the continuous, effective, and safe use of herbicides, minimizing harmful impacts on ecosystems. Features: Explains the radiometric method with studies of radiolabelled herbicides and includes case studies as examples Describes radiometric methods to study the behavior of herbicides in soil from transport and transformation to retention Elucidates the absorption, translocation, and metabolism studies of herbicides in plants Authored by a team of leading scientists, this book is written for professors, researchers, extensionists, graduate and undergraduate students, rural producers, and other professionals involved in weed science.

The Symposium on the Use of Isotopes in Weed Research was convened jointly by the Food and Agriculture Organization of the United Nations and the International Atomic Energy Agency, and was held in Vienna at the Headquarters of IAEA from 25 to 29 October 1965. It provided an occasion for the exchange of information on recent advances in the subject. Additionally it gave an opportunity for investigators who had not used isotopes in their research to assess the potentialities and applications of this technique. Isotopes have already been extensively used in weed research, particularly for studying the comparative absorption of herbicides by different plant species and the movement and distribution of the herbicide within the plant. Radioisotopes have proved of particular value in these studies through the ability of autoradiographic techniques to detect even the trace amounts involved. The mode of action of herbicides has also been quite widely studied through the use of isotopes. It is probably a general rule that the practical selective herbicidal nature of a chemical compound is usually known some time before the actual metabolic mode of action is traced. Nevertheless the mode of action is of great importance, as its study may lead to the development of other herbicides; isotope techniques may be expected to play an increasing role here. Weed control is a continuing world agriculture problem of serious dimensions and there is constant effort both to develop and utilize herbicides. As part of the general widespread concern over the residual effects of chemicals applied to crop plants, the study of herbicide residues in plants and soil, and the detoxification of herbicides, has become essential. For these studies isotopic techniques can be usefully used to identify degradation products and trace the ultimate fate of the herbicide. Such studies are of growing importance. Features of the Symposium were the two informal seminars, which were actively supported and resulted in lively discussions. These seminars provided opportunities for very free exchange of experience and views, enabling participants to define present problems and to discuss useful areas of isotope application. The complete proceedings emphasize the wide scope of isotopes in herbicide and weed research.
