Description

Crop Safeners for Herbicides aims to discuss the issue of chemical manipulation of crop tolerance to herbicides. This book resulted from a symposium titled ""Chemical Manipulation of Crop Tolerance to Herbicides"". Several chapters included herein are added contributions from experts outside of the symposium. The book not only serves as reference for the knowledge of the agronomic uses, development, chemistry, and mechanisms of action herbicide safeners, but it also assesses the impact of safeners all around the world. It also presents a discussion on alternative approaches that increases herbicide selectivity and explores future trends. Comprised of 16 chapters and divided into four parts, the book starts with a section on the development and uses of herbicide safeners. The text also offers a critical and extensive review of academic and industrial perspectives in the development of herbicide safeners in different parts of the world. Part 2 of this book starts with an overview of the physiological, biochemical, and molecular aspects of the mechanisms, and then further delves in to the prevalent mechanisms of action of selected classes of herbicide safeners. The third part of this book provides data on the potential use of alternative approaches for the manipulation of crop tolerance to herbicides. The last part is a summary of the progress and prospects of the topic of crop safening against herbicide injury. The book serves as an important resource for students and professionals interested in the field of agriculture, agronomy, pest research, weed science, and plant pathology and physiology.
