Crop Safeners of Herbicides: Development, Uses, and Mechanisms of Action.

Crop Safeners for Herbicides: Development, Uses, and Mechanisms of Action. Edited by Kriton K. Hatzios and Robert E. Hoagland (Academic Press, 1250 Sixth Avenue, San Diego, CA 92101, 1989, xiv + 400 pp. US $69.95. Progress from both the academic and industrial perspectives in the safening of crops from the action of herbicides is described in the 16 chapters comprising this book. Background to the topic and examples of the successful field application of chemical safeners are presented in the two chapters of Part I. The next part consisting of eight chapters concerns the mechanism of action of herbicide safeners. Then, alternative approaches to the manipulation of crop tolerance to herbicides, such as the use of activated charcoal and other adsorbents, controlled released formulations of herbicides, prosafeners and microbial safeners, are discussed in the five chapters of Part III. The final chapter reviews progress, cites areas that need to be investigated and discusses prospects for safeners. An appendix, which provides chemical names corresponding to the common names for herbicides and safeners mentioned in the text, and an index complete the book.

Each chapter ends with a compilation of references and a brief summary and discussion section in which the authors highlight specific areas requiring further study. As often is the case for multiauthored books, there is some repetition. For example, safeners for the thiocarbamate and the chloroacetanilide herbicideds are discussed in several chapters. This reflects the rather limited number of practical applications to date of chemical safeners for protection of crops against herbicide injury.

This book appears to be directed much more to weed scientists, agronomists, plant biochemists and physiologists than to chemists although those with responsibilities in the herbicide area should certainly find it of interest. In general, it should serve as a valuable source of information concerning the chemical enhancement of herbicide selectivity and should motivate future research in this area. Information obtained from the study of herbicide safeners may also be applicable to the protection of plants from other toxic substances in the environment. A.N. Starratt, FCIC Agriculture Canada
