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.

Herbicides are one of the most widely used groups of pesticides worldwide for controlling weedy species in agricultural and non-crop settings. Due to the extensive use of herbicides and their value in weed management, herbicide research remains crucial for ensuring continued effective use of herbicides while minimizing detrimental effects to ecosystems. Presently, a wide range of research continues to focus on the physiology of herbicide action, the environmental impact of herbicides, and safety. The authors of Herbicides, Physiology of Action, and Safety cover multiple topics concerning current valuable herbicide research.

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.

Over the past 50 years, triazines have made a great impact on agriculture and world hunger by assisting in the development of new farming methods, providing greater farming and land use capabilities, and increasing crop yields. Triazines are registered in over 80 countries and save billions of dollars a year. The Triazine Herbicides is the one book that presents a comprehensive view of the total science and agriculture of these chemicals. With emphasis on how the chemicals are studied and developed, reviewed, and used at the agricultural level this book provides valuable insight into the benefits of triazine herbicides for sustainable agriculture. - Presents previously unpublished information on the discovery, development and marketing of herbicides - Includes a vital section on the origin, use, economics and fate of triazine herbicides - Covers benefits of triazines in corn and sorghum, sugarcane, citrus, fruit and nut crops - Establishes best management practice and environmental benefits of use in conservation tillage

Over the past 30 years one alarming trend is the emergence of plant species resistant to agrochemicals (e.g. insecticides, herbicides, fungicides). Considering the fact that these pesticides are crucial to human health and to food, feed and fiber production, impressive research was carried out during the last decade to understand the mechanisms of resistance development. This volume reviews the latest results and examines the implications of these findings for delaying or avoiding resistance in plants to agrochemicals.

The effects of artificial (and natural) pesticides on organisms other than the target organisms and on the environment in general have become increasingly important in recent years. This has been accentuated by the concerns over the damage these products can do to human health. This book considers pesticides from their fundamental properties as selective control agents. In the first part of this book, the mechanisms of action and basis of selectivity are considered for herbicides including plant growth regulators, fungicides, insecticides, vertebrate control agents and the dose rates required to achieve the desired effects. The second part of the book uses these factors to address environmental and health concerns about pesticides. Key features include descriptions of modern pesticides, modern risk assessments for both environment and public health, and a final comparative chapter on relative risk analysis of pesticides.

In recent decades, repeated use of herbicides in the same field has imposed selection for resistance in species that were formerly susceptible. On the other hand, considerable research in the private and public sectors has been directed towards introducing herbicide tolerance into susceptible crop species. The evolution of herbicide resistance, understanding its mechanisms, characterisation of resistant weed biotypes, development of herbicide-tolerant crops and management of resistant weeds are described throughout the 36 chapters of this book. It has been written by leading researchers based on the contributions made at the International Symposium on Weed and Crop Resistance to Herbicides held at Córdoba, Spain. This book will be a good reference source for research scientists and advanced students.
