The updated edition of the classic, fundamental book on weed science
Weed Science provides a detailed examination of the principles of integrated weed management with important details on how chemical herbicides work and should be used. This revised Fourth Edition addresses recent developments affecting weed science. These include the increased use of conservation-tillage systems, environmental concerns about the runoff of agrochemicals, soil conservation, crop biotechnology, resistance of weeds and crops to herbicides, weed control in nonagricultural settings and concerns regarding invasive plants, wetland restoration, and the need for a vastly improved understanding of weed ecology.
Current management practices are covered along with guidance for selecting herbicides and using them effectively. To serve as a more efficient reference, herbicides are cross-listed by chemical and brand name and grouped by mechanism of action and physiological effect rather than chemical structure. In addition, an introduction to organic chemistry has been added to familiarize readers with organic herbicides. Also included are guidelines on weed-control practices for specific crops or situations, such as small grains, row crops, horticultural crops, lawns and turf, range land, brush, and aquatic plant life.
Generously supplemented with 300 drawings, photographs, and tables, Weed Science is an essential book for students taking an introductory course in weed science, as well as a reference for agricultural advisors, county agents, extension specialists, and professionals throughout the agrochemical industry.

Rewritten to increase the emphasis on the use of safe and low environmental impact herbicides. It is a detailed examination of the principles and practices of weed science and weed control through the use of chemical herbicides. Describes the development of new, low toxicity herbicides as well as other, more effective methods of weed control based on greater study of the biology and ecology of weeds. Also provides guidance on weed control practices for specific crops or situations.
The science of weed control has advanced more during the past 50 years than in the previous 100 centuries. In this book, the old reliable weed control methods are integrated with modern chemical techniques. Together, these practices result in more effective and less expensive weed control programs. Weed Science, Third Edition also focuses on the growing interest in the environmental impact and safety of weed control practices and the development of new herbicides of low mammalian toxicity that can be used at very low rates. It features new material on the biology and ecology of weeds and the use of more effective control methods. More details on the use of herbicides are now provided and the common names and trade names of herbicides are cross-indexed in the appendix for quick, easy access. This invaluable work is organized into three sections—Principles, Herbicides, and Practices. The first section deals with the basic concepts underlying material that is presented in the following sections. It also covers such topics as weed biology and ecology, weed management practices, environmental impact and herbicide registration, herbicides and the plant, herbicides and the soil, and the application equipment and formulation. The second section is subdivided into 23 chemical classes of over 120 individual herbicides. It gives their general properties, influences of soil, mode of action, and uses. Other important topics presented include crop or use sites, rate of application, herbicide combinations, and method of application. Finally, the last section covers weed control practices in specific crops, lawn, turf and ornamentals, pastures and rangelands, brush and undesirable tree control, aquatic weed control and total vegetation control. The book also discusses application techniques, control of spray drift, volatility, and similar basic principles in depth. In addition to its use as a textbook in college and university classrooms, this revised Third Edition is an invaluable addition to the reference library of extension specialists, county agents, pesticide advisors, agricultural consultants, herbicide manufacturers, agriculture, and landscape architects.
