Chemical delivery system site-specific enzyme-activated

Most, if not all, of the compounds mentioned in this volume have arisen through the systematic screening of novel chemicals and the identification of active lead compounds. The subsequent development of more active analogues and suitable formulation/delivery systems illustrates the ingenuity and expertise of the R D chemists/biologists involved in the launch of a new herbicide. While this approach has been eminently successful, there is a view that, ideally, novel compounds should be tailored to fit specific enzyme receptor sites. This aim will be achieved only with improved understanding of the molecular architecture of the site(s) and the molecular requirements for transport into and within the plant. The approach taken in this book should serve to illuminate the problems and possible solutions.
