Despite the continuing effort to develop more environmentally friendly alternatives, traditional herbicides continue to be the major weapon against weeds in North America. The contribution made by herbicides to modern crop production in North America is spectacular and in order for effective development of new, safer agrochemicals to be formulated, it is essential for researchers to understand how these compounds work in plants and their surrounding environment. Although herbicides may be marketed internationally under different trade names in different countries, they are often generically identical. Hence the information drawn together in this book will be of interest on both sides of the Atlantic. This volume aims to provide an 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 and includes many specially prepared illustrations.
