Fundamentals of Weed Science, Fifth Edition, provides the latest information on this constantly advancing area of study. Placing weed management in the largest context of weed research and science, the book presents the latest advances in the role, control and potential uses of weed plants. From the emergence and genetic foundation of weeds, to the latest means of control and environmental impact, the book uses an ecological framework to explore the role of responsible and effective weed control in agriculture. In addition, users will find discussions of related areas where research is needed for additional understanding. Explored topics include the roles of culture, economics and politics in weed management, all areas that enable scientists and students to further understand the larger effects on society. - Winner of a 2019 The William Holmes McGuffey Longevity Award (College) (Texty) from the Textbook Association of America - Completely revised with 35% new content - Contains expanded coverage of ethnobotany, the specific identity and role of invasive weed species, organic agriculture, and herbicide resistance in GM crops - Includes an emphasis on herbicide resistance and molecular biology, both of which have come to dominate weed science research - Covers all traditional aspects of weed science as well as current research - Provides broad coverage, including relevant related subjects like weed ecology and weed population genetics

Fundamentals of Weed Science provides an introduction to the basic principles of weed science for undergraduate courses. It discusses several aspects of weed biology and control, and traces the history of herbicide development. The book begins with an introduction to weeds, covering their definition, characteristics, harmful aspects, and the cost of weed control. This is followed chapters on weed classification, the uses of weeds, weed biology, weed ecology, allelopathy, the significance of plant competition, weed management and control methods, and biological weed control. Later chapters deal with herbicidesthe most important weed control tools and the ones with the greatest potential for untoward effects. Students of weed science must understand herbicides and the factors governing their use as well as the potential for misuse. These chapters discuss chemical weed control, the properties and uses of herbicides, factors affecting herbicide performance, herbicide application, herbicide formulation, ecological impact of herbicides, pesticide registration and legislation, weed management systems, and the future of weed science.

Chemical Ecology contains a series of lectures presented in the fall of 1968 at State University of New York College of Forestry at Syracuse University. This book is composed of 11 chapters that deal with the salient facts and theories that are encompassed by chemical ecology and the possible application of fundamental research in this area to pressing problems of ecological importance. After briefly describing the distribution pattern of microorganisms in the soil, this book goes on exploring the coordination and regulation of sexual processes between cells and between individuals in lower and higher plants. These topics are followed by discussions on the aspects of the chemical environment; the diverse associations between insects and their host plants; the self-defense mechanisms of plants against insect predation; and the chemical communication systems within animal species. The subsequent chapters examine the chemical defense and ecology in arthropods and fish. The concluding chapters consider the biochemistry of terpenoid and steroid metabolism and the chemical aspects of juvenile and steroidal molting hormone interactions. This book will be of value to chemical ecologists and researchers and biochemists.

Plant Physiology, Volume VA: Analysis of Growth: Behavior of Plants and their Organs describes the main events of growth as seen through the behavior of plants and their organs at an organismal level. This book discusses the quantitative interpretation of growth; the effects of environmental factors; the treatment of tropism; and the effects of many exogenous growth-regulating compounds. Organized into five chapters, the book initially describes mathematically the plant growth mechanisms as they relate to the factors that determine morphogenesis. The text also discusses methods for assessing the effects of external conditions and of age on certain important physiological aspects of plant growth. The subsequent chapter deals with phyllotaxis as a selected aspect of the interpretation of growth and form. The third chapter describes various phototropically and geotropically sensitive systems impinge upon on plant growth. This chapter also covers some reversible nastic movements of organs and the tactic movements of free swimming cells. The next chapter deals with relations between the chemical structure of synthetic compounds and their biological action. The last chapter focuses on the modulation of growth and development by features of the environment and also upon experimental manipulation and under controlled conditions of growth. This volume is an invaluable resource for plant biologists, physiologists, and researchers.

With a claim to be the first work to document in detail the history of allelopathy, Willis’s text provides an account of the concept of allelopathy as it has occurred through the course of botanical literature from the earliest recorded writings to the modern era. A great deal of information is presented here in a consolidated and accessible form for the first time. The book offers a unique insight into the historical factors which have influenced the popularity of allelopathy.
