Weeds hold an enigmatic and sometimes-controversial place in agriculture, where they are generally reviled, grudgingly tolerated, and occasionally admired. In most cases, growers make considerable effort to reduce the negative economic impact of weeds because they compete with crops for resources and hinder field operations, thereby affecting crop productivity and quality, and ultimately the sustainability of agriculture. Weed control in production agriculture is commonly achieved through the integration of chemical, biological, and mechanical management methods. Chemicals (herbicides) usually inhibit the growth and establishment of weed plants by interfering with various physiological and biochemical pathways. Biological methods include crop competition, smother crops, rotation crops, and allelopathy, as well as specific insect predators and plant pathogens. Mechanical methods encompass an array of tools from short handled hoes to sophisticated video-guided robotic machines. Integrating these technologies, in order to relieve the negative impacts of weeds on crop production in a way that allows growers to optimize profits and preserve human health and the environment, is the science of weed management.

This book offers a global perspective on weed science by presenting contributions from an outstanding group of researchers in 12 countries, reviewed by over 50 experts. It discusses technologies, which could relieve the negative impacts of weeds on crop production in a way that allows growers to optimise profits and preserve human health and the environment. These technologies represent the science of weed management. The aim of the book is to provide insight and recent progress in the science of weed research. Articles presenting the novel and critical appraisals of specific topics are included.

"Weeds are rarely considered a priority despite the fact that all active farmers know that the majority of their variable costs and time are devoted to eradicating them. Even most crop losses due to pests can be traced directly back to weeds, which harbor the pests as secondary hosts. In the Molecular Biology of Weed Control, Jonathan Gressel focuses attention upon the tools of molecular biology that can be used effectively in the science of weed control. Always keeping his perspective congruent with that of the working farmer, Gressel explains how weed biologists and ecologists are beginning to use recently developed tools to control intransigent weed species in modern as well as less developed areas of the world. With his usual candor, Gressel evaluates past efforts, while also exploring future prospects for replacing chemical herbicides with genetic engineering, to improve a crop's ability to compete against its feral cousins for light, nutrients, and water. Like much of Gressel's work, this book should be mandatory reading for all agriculturists and plant scientists, so that they employ and encourage what is truly effective and efficient in meeting one of this century's most critical challenges: maximizing agricultural productivity.

Ziska (plant physiology, United States Department of Agriculture) and Dukes (biological sciences, Purdue University) explain in clear terms the functions of weeds in world ecology. From defining a weed, a term that exists only in relation to human needs, to explaining the effects of increased carbon dioxide on the spread of weeds, the authors gather together information from a plethora of scientific monographs and put them into a form understandable to the general reader. They cover the constant battle between food crops and weeds for the nutrients in the soil and methods used by farmers to combat the latter. Ziska and Dukes also discuss the effects of the herbicides used and the problems encountered when people introduce natural predators, such as kudzu, to non-native areas. They note the allergic affect many plants, especially ragweed, have on sensitive people. Lastly, they suggest ways to keep weeds under control while continuing to study them for beneficial properties. Throughout, the authors remind the reader of the interconnectedness of plants, animals and climate.

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.

Refecting what a new generation of conservation biologists is doing and thinking, this vital and far ranging second edition explores where conservation biology is heading. It challenges many conventions of conservation biology by exposing certain weaknesses of widely accepted principles. Combining contributions from both the school and the new breed of conservation biologists, this insightful text focuses primarily on topics the are integral to the daily activities of conservation biologists. Several chapters address ecosystem restoration and biotic invasions as well as the the mechanics of population viability analyses, which are now a routine facet of conservation efforts. A case history approach is implemented throughout the book, with the use of practical real-world examples. Furthermore, an in-depth look at quantitative analyses is presented, allowing for models and mathematical analyses to pinpoint limitations in existing data and guide research toward those aspects of biology that are most likely to be critical to the dynamics of a species or an ecosystem.
