Weeds hold an enigmatic and sometimes controversial place in agriculture, where they are generally reviled, grudgingly tolerated, and occasionally admired. Weeds affect crop productivity and quality, and ultimately the sustainability of agriculture. This makes them an important object of scientific study. 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. The topics of ecology (i), management of invasive plants (ii), evolutionary biology of foxtail species (iii), the benefits of weeds (iv), ecological and physiological aspects of weed/crop competition and chemical control (v), aquatic weed management and characteristics of weed management

Biological control of plant diseases and plant pathogens is of great significance in forestry and agriculture.

Biological invasions are one of the major threats to our native biodiversity. The magnitude of biodiversity losses, land degradation and productivity losses of managed and natural ecosystems due to invasive species is enormous. The ecological and environmental aspects of non-native invasive plants are of great importance to (i) understand ecological principles involved in the management of invasives, (ii) design management strategies, (iii) find effective management solutions for some of the worst invaders, and (iv) frame policies and regulations. The objectives of this book are to discuss (i) ecological approaches needed to design effective management strategies, (ii) recent progress in management methods and tools, (iii) success and failure of management efforts for some of the worst invaders, and (iv) restoration and conservation of invaded land. In an effort to achieve these objectives, contributing authors have strived to provide up-to-date information on the management of non-native invasives. Chapters included in the book are peer-reviewed by international experts working in the area. Readers will get a unique perspective on ecological aspects of the management of invasives. The book will be useful to graduate students, researchers, managers and policy makers involved in the management of exotic invasives.

Allelochemicals play a great role in managed and natural ecosystems. Apart from plant growth, allelochemicals also may influence nutrient dynamics, mycorrhizae, soil chemical characteristics, and microbial ecology. Synergistic action of various factors may better explain plant growth and distribution in natural systems. The book emphasizes the role of allelochemicals in shaping the structure of plant communities in a broader ecological perspective. The book addresses the following questions: (1) How do allelochemicals influence different components of the ecosystem in terms of shaping community structure? (2) Why is it difficult to demonstrate interference by allelochemicals (i.e., allelopathy) in a natural system in its entirety? Despite a large amount of existing literature on allelopathy, why are ecologists still skeptical about the existence of allelopathy in nature? (3) Why are there only scarce data on aquatic ecosystems? (4) What role do allelochemicals play in microbial ecology?.....

In spite of a large amount of existing literature on allelopathy, why are ecologists still sceptical about the existence of allelopathy in nature? (3) Why are there only scarce data on aquatic ecosystems? (4) What role do allelochemicals play in microbial ecology? And how does altered soil microbial ecology influence community structure and fate of allelochemicals?(5) What role do allelochemicals play in nutrient dynamics in terms of final influence on plant growth and distribution? (6) How do abiotic and biotic factors of an ecosystem influence the functioning of allelochemicals? (7) What are the main pitfalls in presentation, analysis and interpretation of allelochemical data?
