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.
A History of Weed Science in the United States by Robert L Zimdahl Pdf
It is important that scientists think about and know their history - where they came from, what they have accomplished, and how these may affect the future. Weed scientists, similar to scientists in many technological disciplines, have not sought historical reflection. The technological world asks for results and for progress. Achievement is important not, in general, the road that leads to achievement. What was new yesterday is routine today, and what is described as revolutionary today may be considered antiquated tomorrow. Weed science has been strongly influenced by technology developed by supporting industries, subsequently employed in research and, ultimately, used by farmers and crop growers. The science has focused on results and progress. Scientists have been--and the majority remain--problem solvers whose solutions have evolved as rapidly as have the new weed problems needing solutions. In a more formal sense, weed scientists have been adherents of the instrumental ideology of modern science. That is an analysis of their work, and their orientation reveals the strong emphasis on practical, useful knowledge; on know how. The opposite, and frequently complementary orientation, that has been missing from weed science is an emphasis on contemplative knowledge; that is, knowing why. This book expands on and analyzes how these orientations have affected weed science’s development. The first analytical history of weed science to be written Compares the development of weed science, entomology and plant pathology Identifies the primary founders of weed science and describes their role
"The natural histories of eight ordinary plant species transformed into noxious weeds through mostly well-intended human efforts to get rid of them show how lives of people and weeds are entangled in ways that reflect human beliefs and attitudes toward the natural world" --
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.
A wide-ranging scientific and cultural history of weeds that reveals just how interesting and useful these seemingly annoying plants can be. We spray them, pluck them, and bury them under mulch; and we curse their resilience when they spring back into place. To most of us, weeds are a nuisance, not worth the dirt they are growing in. But the fact is weeds are a plant just like any other, and it is only we who designate them as a weed or not, as a plant we will dote over or one we will tear out of the earth with abandon. And as Nina Edwards shows in this history, that designation is constantly changing. Balancing popular history with botanical science, she tells the story of the lowly, but proud, weed. As Edwards shows, the idea of the weed is a slippery one, constantly changing under different needs, fashions, and contexts. In a tightly controlled field of corn, a scarlet poppy is a bright red intruder, but in other parts of the world it is an important cultural symbol, a potent and lucrative pharmaceutical source, or simply a beautiful, lakeside ornament. What we consider a pest—Aristolochia Rotunda, or “fat hen”—was, in Neolithic times, a staple crop, its seeds an important source of nutrition. Sprinkled with personal anecdotes and loads of useful information, Weeds sketches history after history of the fashions and attitudes that have shaped our gardens, showing us that it is just as important what we keep out of them as what we put in, and that just because we despise one species does not mean that there haven’t been others whose very lives have depended on it.
Weeds survive, entombed in the soil, for centuries. They are as persistent and pervasive as myths. They ride out ice ages, agricultural revolutions, global wars. They mark the tracks of human movements across continents as indelibly as languages. Yet to humans they are the scourge of our gardens, saboteurs of our best-laid plans. They rob crops of nourishment, ruin the exquisite visions of garden designers, and make unpleasant and impenetrable hiding places for urban ne'er-do-wells. Weeds can be destructive and troubling, but they can also be beautiful, and they are the prototypes of most of the plants that keep us alive. Humans have grappled with their paradox for thousands of years, and with characteristic verve and lyricism, Richard Mabey uncovers some of the deeper cultural reasons behind the attitudes we have to such a huge section of the plant world.
Handbook of Sustainable Weed Management by Harinder P. Singh,Daizy Rani Batish,Ravinder Kumar Kohli Pdf
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
Invasive Plant Species of the World, 2nd Edition by Ewald Weber Pdf
Since the publication of the first edition of this book in 2003, the status of many important invasive plants around the world has changed dramatically. Species have extended their ranges, new literature has been accumulated, and control methods have been improved. Research on some plant invaders has also focused on the species' ecology and impacts, confirming that invasive plants continue to pose serious threats to species and ecosystems. Given their range expansions and introduction via international trade, these problems will only become more serious in the future. Including colour images of each species, this up-to-date reference guide on the most important plant invaders is an invaluable tool for both researchers and policy makers.
Charles Walters, founder and long-time editor of Acres U.S.A., the monthly journal of eco-agriculture, has revised and expanded his now classic text on the secrets that weeds reveal to us about our soil. For a thorough understanding of the conditions that produce certain weeds, you simply can't find a better source than this one -- certainly not one as entertaining, as full of anecdotes and home-spun common sense.
World Weeds by LeRoy Holm,Jerry Doll,Eric Holm,Juan V. Pancho,James P. Herberger Pdf
Responsible for a high proportion of the world's crop losses, weedstake away food that the world badly needs. They decrease thequality and quantity of vegetable fibers, wool, and hides, andinterfere with fishing, irrigation, hydroelectric power production,and the movement of shipping vessels.
