Weed populations in agriculture are a major cause of yield loss. Conventionally, crop rotation and tillage practices limit the number of weed flora. Several chemical herbicides are being applied to control weed growth, but the long-term use of those chemicals does not effectively control weeds, due to the development of resistant germplasms, which cause hazardous effects in living organisms. The global interest in organic farming endorses the alternative way of weed control against chemical herbicides. Recently, biological agents have been added to integrated weed management strategies. Several studies reveal that plant extracts, bacteria, fungi and their products effectively control weed seed germination and growth. The aim of this book is to discuss the current understanding of bioherbicides and strategies to weed control.

Innovative Strategies for Managing Weeds in an Environmentally Protective Manner Successfully meeting the challenge of providing weed control without relying on dangerous chemicals that endanger the ecosystem or human lives, this compendium focuses on management strategies that reduce herbicidal usage, restore ecological balance, and increase food production. It also provides new insights and approaches for weed scientists, agronomists, agriculturists, horticulturists, farmers, and extentionists, as well as teachers and students. In the Handbook of Sustainable Weed Management, experts from Asia, Europe, North America, and Australia organize in one resource information related to weeds and their management from different ecosystems around the world that has been until now been scattered throughout the literature.. The text captures the multifaceted impacts of and approaches to managing weeds from field, farm, landscape, regional, and global perspectives. Generously illustrated with tables and figures, this book not only describes the various techniques for weed management but shows you what methods work best in a given region, or in response to a specific, invasive weed or invaded crop. Covering the full scope of modern weed science the handbook examines different aspects of weed management, including— • Cultural practices • Cover crops • Crop rotation designs • Potential of herbicide resistant crops • Bioherbicides • Allelopathy • Microorganisms • Integrated weed management In spite of advancement in technologies and procedures, weeds continue to pose a major ecological and economical threat to agriculture. Handbook of Sustainable Weed Management takes a broad view of weeds as a part of an agricultural system composed of interacting production, environmental, biological, economic, and social components all working together to find balance. This comprehensive book is a vital addition to the debate over how global weed management is changing in the 21st century. Also available in soft cover

Weeds are the main biological constraint to crop production throughout the year. Uncontrolled weeds could cause 100% yield loss. In Australia, the overall cost of weeds to Australian grain growers was estimated at AU$ 3.3 billion annually. In terms of yield losses, weeds amounted to 2.7 million tonnes of grains at a national level. In the USA, weeds cost US$ 33 billion in lost crop production annually. In India, these costs were estimated to be much higher (US$ 11 billion). These studies from different economies suggest that weeds cause substantial yield and economic loss. Biology and Management of Problematic Weed Species details the biology of key weed species, providing vital information on seed germination and production, as well as factors affecting weed growth. These species include Chenopodium album, Chloris truncata and C. virgate, Conyza bonariensis and C. canadensis, Cyperus rotundus, and many more. This information is crucial for researchers and growers to develop integrated weed management (IWM) strategies. Written by leading experts across the globe, this book is an essential read to plant biologists and ecologists, crop scientists, and students and researchers interested in weed science. Provides detailed information on the biology of different key weed species Covers weed seed germination and emergence Presents the factors affecting weed growth and seed production

Technology is rapidly advancing in all areas of society, including agriculture. In both conventional and organic systems, there is a need to apply technology beyond our current approach to improve the efficiency and economics of management. Weeds, in particular, have been part of cropping systems for centuries often being ranked as the number one production cost. Now, public demand for a sustainably grown product has created economic incentives for producers to improve their practices, yet the development of advanced weed control tools beyond biotech has lagged behind. An opportunity has been created for engineers and weed scientists to pool their knowledge and work together to ‘fill the gap’ in managing weeds in crops. Never before has there been such pressure to produce more with less in order to sustain our economies and environments. This book is the first to provide a radically new approach to weed management that could change cropping systems both now and in the future.
