A review of the most important areas of the biochemistry of herbicide action. The introductory chapter begins with the field of herbicide discovery, followed by chapters dealing with the herbicidal inhibition of photosynthesis, carotenoid biosynthesis, lipid biosynthesis, and amino acid biosynthesis. The metabolism of herbicides is discussed with particular reference to the formation of toxic components from non-toxic chemicals, and also the inactivation of toxic chemicals as a basis for selectivity. The final chapters are concerned with mechanisms of herbicide resistance in plants and the possibility of transferring resistance to susceptible crops. A glossary of the most important herbicidal chemicals mentioned in the text is included.

Herbicides are part of modern agricultural production systems and therefore contribute significantly to the economy of agricultural products. At the same time, herbicides are potent and specific inhibitors of plant metabolism and may therefore be used as valuable tools in basic plant physiological research. A well-known example is the photosynthesis-inhibiting herbicide diuron, known to plant physiologists as DCMU, which has become one of the essentials in modern photosynthesis research. Similarly, knowledge in other areas of plant metabolism may be advanced by the use of herbicides as specific inhibitors. This book describes the effects of herbicides on the metabolism of higher plants from the viewpoint of the plant physiologist. The material of this book is therefore, as far as possible, divided into areas of metabolism. This book intends (1) to present the reader with current knowledge and views in the area of herbicide modes of action and (2) to promote the future use of herbicides as metabolic inhibitors in plant physiological research to the advantage of both, the pesticide and the plant sciences.

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.

This important publication provides a comprehensive summary of data and information on the metabolism and chemical degradation of agrochemicals in soils, plants and animals. Part 1, Herbicides and Plant Growth Regulators, and Part 2, Insecticides and Fungicides, together provide a major bibliography, as each entry is fully referenced. Contents include metabolic products, pathways and mechanisms, together with useful details on physico-chemical properties and mode of action. Both parts are organised by class of chemical for easy reference. There are separate entries for each pesticide, covering most commercially available chemicals in use today. In addition, an overview of the metabolism of each major class provides the reader with an informed summary of key similarities and significant differences between individual chemicals. Information is based primarily on literature from the past 40 years of research, together with some important, previously unpublished work provided by the agrochemical companies. Presented in a systematic, easy-to-read style, with extensive indexing to facilitate the rapid location of required information and the comparison of related compounds, Metabolic Pathways of Agrochemicals is an invaluable reference for chemists, biochemists and biologists working in the discovery, development and registration of agrochemicals, as well as scientists in related areas such as design and mode of action of pharmaceuticals.

The use of herbicides is increasing rapidly year by year. 2,4-Dichlorophenoxyacetic acid (2,4-D) is the most widely used of the herbicides offered on the market. Although 2,4-D was one of the first selective herbicides discovered and has been investigated by many workers over the years, there are still many questions concerning its metabolism. Hydroxylated derivatives have been found in some microorganisms and plants . This might be expected as hydroxylation is a prime method of detoxication in biological systems. 2,4-D has been found to be hydroxylated predominantly in the 5-position. However, 4- hydroxy-2,3- and 4-hydroxy-2,5-dichlorophenoxyacetic acids have been identified in some cases. This is interesting as it involves much more elaborate mechanisms than hydroxylation in a vacant position. The formation of these hydroxy acids requires a chlorine shift to one of the meta positions and hydroxylation in the para position. The object of this work is to determine whether hydroxylated derivatives are formed by excised roots from 2,4-D or related herbicides. Some workers have also found muconic acids and gamma-lactones as succeeding stages in the metabolism of these herbicides. This would follow from an oxidative degradation of the ring structure. The lactones found are of interest from the public health standpoint. The gamma-lactones isolated contain double bonds in the even numbered positions and compounds of this type have been found to be carcinogenic. If these compounds appear in any appreciable amounts and are not very transitory in nature, the use of the herbicides involved might require reevaluation by regulating organizations.

Developments in the understanding of herbicide activity and toxicology have expanded tremendously in the past fifteen years. Research on the mechanism of action of most major classes of herbicide chemistry has provided scientists with excellent insight into enzyme targets. More recently, developments in molecular biology have provided information about herbicide action at the genetic level. Less well understood are the toxicological aspects of herbicide activity that culminate in plant injury or death. Toxicology, Biochemistry and Molecular Biology of Herbicide Activity is a review of the recent literature on most of the major classes of herbicide chemistry in commercial use. The chapters include information about different aspects of herbicide activity related to photosynthesis, inhibition of amino acid biosynthesis, disruption of cell division and microtubule assembly, activity of phytohormone (auxin) mimics, inhibition of fatty acid biosynthesis and some developments in the understanding of herbicide resistance.

The development of chemicals to selectively control the growth of weeds has been a fascinating success story which has unfolded largely during the last four decades. The dramatic growth of herbicide research that followed the wartime discoveries of the auxin-type herbicides (phenoxyalkanoic acids) resulted in a whole range of compounds and mixtures which are used to eliminate broad-or narrow-leaved weeds from agricultural, horticul tural, or forestry crops. Today, the safe use of this armament of compounds requires our understanding of their mode of action, metabolism, and environmental persistence. The most recently developed herbicides are highly effective inhibitors of specific enzyme systems, and formulation may be an important factor determining their efficient delivery at specific target sites. In this book, the major target sites of herbicide action are discussed in Chapters 1-5, with particular reference to photosynthesis; amino acid, lipid, and carotenoid synthesis; and other primary target sites. The effects of synergists or antagonists as modifiers of herbicide action are described in Chapter 6. The importance of efficient target site delivery as a fundamental factor in herbicide activity and selectivity is generally recognized. Delivery of a potentially lethal dose of active ingredient may depend on a whole range of factors including the efficiency of application, retention, absorption, translocation, immobilization, and detoxification. These aspects are con sidered in the remaining chapters, with particular reference to the pathways and mechanisms involved in the uptake, translocation, and metabolism of soil-and foliage-applied herbicides.
