Weeds are problematic both in agricultural and non-agricultural areas so that they potentially cause economic losses. Weed interference in crops also date back to the beginning of agriculture and they have been able to persist, in spite of long term control operations. They are able to adapt and survive in the environment due to their specific characteristics. Thus, to control weeds efficiently knowledge of weed biology, in particular their survival mechanisms, ecological responses and interactions, is of important value in weed management systems. "Weeds and their Ecological Functions" provides information on weeds functional behaviours in their cultivations including weed seed dormancy, germination and seedling emergence, examples of beneficial and detrimental interactions between weeds and other organisms, weed behaviours in perennial crops and response of weeds to cover crops. This information is useful for students and weed scientists to analyse some of the functional behaviour of weeds and to develop integrated weed management systems.

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.

This book presents principles and practices for ecologically based weed management in a wide range of temperate and tropical farming systems. Special attention is given to the evolutionary challenges that weeds pose and the roles that farmers can play in the development of new weed-management strategies.

This book, first published in 2005, addresses food-mediated interactions, focusing on how plants employ foods to recruit arthropod 'bodyguards' as a protection against herbivores.

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.

Weed Biology and Climate Change will provide a synthesis of what is known regarding the probable impact of environmental change on weed biology. Chapters will look at impacts of weed biology on agriculture, invasive species that limit ecological diversity and weeds that serve as health risks. In addition it looks at current weed management strategies and how they will be affected by global climate change. The book covers an increasingly important area in plant science, crop science and ecological research, and will be essential reading for anyone exploring the biological impacts of a changing environment.

The Wild Wisdom of Weeds is the only book on foraging and edible weeds to focus on the thirteen weeds found all over the world, each of which represents a complete food source and extensive medical pharmacy and first-aid kit. More than just a field guide to wild edibles, it is a global plan for human survival. When Katrina Blair was eleven she had a life-changing experience where wild plants spoke to her, beckoning her to become a champion of their cause. Since then she has spent months on end taking walkabouts in the wild, eating nothing but what she forages, and has become a wild-foods advocate, community activist, gardener, and chef, teaching and presenting internationally about foraging and the healthful lifestyle it promotes. Katrina Blair’s philosophy in The Wild Wisdom of Weeds is sobering, realistic, and ultimately optimistic. If we can open our eyes to see the wisdom found in these weeds right under our noses, instead of trying to eradicate an “invasive,” we will achieve true food security. The Wild Wisdom of Weeds is about healing ourselves both in body and in spirit, in an age where technology, commodity agriculture, and processed foods dictate the terms of our intelligence. But if we can become familiar with these thirteen edible survival weeds found all over the world, we will never go hungry, and we will become closer to our own wild human instincts—all the while enjoying the freshest, wildest, and most nutritious food there is. For free! The thirteen plants found growing in every region across the world are: dandelion, mallow, purslane, plantain, thistle, amaranth, dock, mustard, grass, chickweed, clover, lambsquarter, and knotweed. These special plants contribute to the regeneration of the earth while supporting the survival of our human species; they grow everywhere where human civilization exists, from the hottest deserts to the Arctic Circle, following the path of human disturbance. Indeed, the more humans disturb the earth and put our food supply at risk, the more these thirteen plants proliferate. It’s a survival plan for the ages. Including over one hundred unique recipes, Katrina Blair’s book teaches us how to prepare these wild plants from root to seed in soups, salads, slaws, crackers, pestos, seed breads, and seed butters; cereals, green powders, sauerkrauts, smoothies, and milks; first-aid concoctions such as tinctures, teas, salves, and soothers; self-care/beauty products including shampoo, mouthwash, toothpaste (and brush), face masks; and a lot more. Whether readers are based at home or traveling, this book aims to empower individuals to maintain a state of optimal health with minimal cost and effort.
