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

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.

Weeds are successful plants, but on their own terms. Looking at weeds from an ecological viewpoint, emphasising the way in which one species interacts with others, the authors show that weeds are questionable mainly in that they are out-of-place.

Offering much new information on the subject, this volume discusses the problems of weed control in sugarcane against the background of world-wide cultivation, with emphasis on Taiwan's intensive pattern of crop farming. After a brief botanical description of sugarcane and its cultivation in relation to weed control, the weeds themselves are studied. Chemical control of weeds, problems of crop tolerance and responses of weed species to chemicals are examined. Techniques for evaluating new herbicides, research and practices of chemical weed control in the leading industries of the world, and the application of techniques and equipment are all described in detail. The author has served the Taiwan sugar industry for more than 30 years and many of his techniques and approaches have been adopted by industries in other countries. To his own extensive experience, he has added a large amount of information published in recent years to compile this treatise which is both a contribution to the field of weed science, and a valuable practical manual for agronomists in general.

Satisfying consumer needs through the production of healthy and nutritious agricultural products is a substantial challenge facing modern agriculture. However, agricultural production should be carried out with care for plant health, biological safety of products, and environmental safety while minimizing the risks to human health. Therefore, the implementation of agricultural practices while respecting these principles is very important for improving the quantity and quality of crops. Additionally, ecosystems have been altered as a result of human activities and climate change, resulting in the reduction of biodiversity and creation of new niches where pests can thrive. This is of particular importance in 2020, as the United Nations General Assembly declared this year as the International Year of Plant Health (IYPH), with “protecting plants, protecting life” as a leading subject. This Special Issue promotes the subject of plant health and emphasize the importance of preventing the spread of pests, including weeds, which cause substantial economic losses. Research articles cover topics related to the biology and harmfulness of weeds, particularly in connection with crop health, segetal weed communities and their biodiversity, and integrated methods of weed control. For this Special Issue, we welcome all types of articles, including original research, opinions, and reviews.

This volume addresses recent developments in weed science. These developments include conservation agriculture and conservation tillage, climate change, environmental concerns about the runoff of agrochemicals, resistance of weeds and crops to herbicides, and the need for a vastly improved understanding of weed ecology and herbicide use. The book provides details on harnessing knowledge of weed ecology to improve weed management in different crops and presents information on opportunities in weed management in different crops. Current management practices are also covered, along with guidance for selecting herbicides and using them effectively. Written by experts in the field and supplemented with instructive illustrations and tables, Recent Advances in Weed Management is an essential reference for agricultural specialists and researchers, government agents, extension specialists, and professionals throughout the agrochemical industry, as well as a foundation for advanced students taking courses in weed science.
