Molecular Mechanisms Of Herbicide Selectivity

Because plants of different species vary in the way in which they take up, transport, and metabolize chemicals in the soil, selective herbicides can be synthesized. This book examines those aspects of plant physiology, principally in crop plants, which can be affected by herbicides; the possibilities that are offered by recombinant DNA technology for developing resistance to herbicides; and methods for exploiting or preventing acquired tolerance. The author also covers recent work on ultra-selective mycoherbicides and the use of allelochemicals as herbicide substitutes.

Herbicides and their Mechanisms of Action highlights issues in herbicide selectivity. Developed with the input of authors from both academia and industry, this volume delivers a comprehensive and up-to-date treatment of the operation of the selectivity mechanisms of herbicides. Even more, the book discusses real-world effects of herbicides, and the results herbicides bring to bear on the environment. The authors emphasize applied aspects of the subject and concentrate on the developments of the last decade, making the book both practical and timely. With the wide variety of herbicides now available for the selective control of weed growth, it is imperative that scientists acquire a detailed understanding of the scientific bases of these herbicides. Indeed, the most recently developed herbicides work by inhibiting the enzyme systems of specific herbs, thereby retarding the growth of those herbs. For maximum effectiveness it becomes crucial that the active ingredients of these herbicides be efficiently delivered on the desired targets. Providing a state-of-the-art appraisal of this important subject, Herbicides and their Mechanisms of Action is the ideal resource for virtually all researchers and professionals involved in the development, administration, and regulation of herbicides.

Herbicide Resistance in Weeds and Crops is a collection of papers presented at the 11th Long Ashton International Symposium in September 1989. The said symposium is held to study about the increasing incidence of herbicide-resistant weeds and the consideration of the production of herbicide-resistant crops. The book includes studies that suggest the delay and prevention of herbicide resistance; the gravity of the infestation of different herbicide-resistant weed; the management of herbicide resistance; and the mechanisms of herbicide tolerance. Also covered in the book are the improvement of different herbicides, as well as the prospective development of genetically engineered herbicide-resistant plants. Botanists, biochemists, and farmers would greatly benefit from the text, especially those who would like to explore and study the phenomenon.

Herbicides make a spectacular contribution to modern crop production. Yet, for the development of more effective and safer agrochemicals, it is essential to understand how these compounds work in plants and their surroundings. This expanded and fully revised second edition of Herbicides and Plant Physiology provides a comprehensive and up-to-date account of how modern herbicides interact with target plants, and how they are used to manage crop production. In addition, the text: Provides a current account of the importance of weeds to crop yield and quality; Describes how new herbicides are discovered and developed; Examines precise sites of herbicide action and mechanisms of herbicide selectivity and resistance; Reviews commercial and biotechnological applications, including genetically engineered herbicide resistance in crops; Suggests new areas for future herbicide development; Includes many specially prepared illustrations. As a summary of diverse research information, this second edition of Herbicides and Plant Physiology is a valuable reference for students and researchers in plant physiology, crop production/protection, plant biochemistry, biotechnology and agriculture. All libraries in universities, agricultural colleges and research establishments where these subjects are studied and taught will need copies of this excellent book on their shelves.

Herbicides are one of the most widely used groups of pesticides worldwide for controlling weedy species in agricultural and non-crop settings. Due to the extensive use of herbicides and their value in weed management, herbicide research remains crucial for ensuring continued effective use of herbicides while minimizing detrimental effects to ecosystems. Presently, a wide range of research continues to focus on the physiology of herbicide action, the environmental impact of herbicides, and safety. The authors of Herbicides, Physiology of Action, and Safety cover multiple topics concerning current valuable herbicide research.

This volume contains two sections: Mechanisms of herbicidal action (chapters 1-4) and Mode of action of selected herbicides on controlling diseased, weed growth and productivity and/or growth and development of field crops (chapters 5-10). Topics by chapters are: molecular mechanism of action, immunosensors , laboratory studies, molecular modeling, weed resistance, community response, use of herbicides in biotech culture, gene flow, herbicides and risk, herbicides persistence. These recurring themes reinforce my view, held over a very long time, that experience with one crop or problem can sometimes be relevant, often to an unexpected extent, to an apparently dissimilar situation in a different crop. I hope that readers interested in herbicides and pesticides will be satisfied with all the chapters in the book as its content might be of interest and value to them in the future.
