Book Description
American Horticultural Society Book Award Winner: “An essential reference for all who wish to understand the science of the all-powerful weed.” —Better Homes and Gardens “What is a weed,” opined Emerson, “but a plant whose virtues have not yet been discovered?” While that may be a worthy notion in theory, these plants of undiscovered virtue cause endless hours of toil for backyard gardeners. Wherever they take root, weeds compete for resources, and most often win. They also wreak havoc on industry—from agriculture to golf courses to civic landscape projects, vast amounts of money are spent to eradicate these virile and versatile invaders. With so much at stake, reliable information on weeds and their characteristics is crucial. Richard Dickinson and France Royer shed light on this complex world with Weeds of North America. Organized by plant family, this encyclopedic volume features over five hundred species in two-page spreads with images and text identification keys. Species are arranged within family alphabetically by scientific name, and entries include vital information on seed viability and germination requirements. No matter what your philosophy on weeds, this guide provides much-needed background on these intrusive organisms. In the battle with weeds, knowledge truly is power, and Weeds of North America is perfect for gardeners, botanists, nature lovers, or anyone working in the business of weed ecology and control. “Royer’s photographs are almost perversely alluring. . . . How can you not be ensnared by a book populated by prostrate pigweed, tansy ragwort and dog-strangling vine?” —New York Times Book Review

Color photos of over 700 weeds including seeds, seedlings, flowers, and mature plants. Appendix of non-native plants rarely or occasionally naturalized in California. Glossary of botanical terms. Bibliography of some of the most pertinent publications. Index to common names, scientific names, and synonyms. Each entry describes the plant category, family name, common name, and synonyms along with a summary of the important aspects of the plant’s life cycle, size, growth form, impact, method of introduction, and toxicity. You'll also find a description of the seedling, mature plant, roots and underground structures, flowers, fruits and seeds, spikelets and florets, spore-bearing structures, and post senescence characteristics for each entry. Also includes a description of the habitat where each is typically found and distribution in California, other states, and worldwide, along with maximum elevation at which the species is found. Rounding out each entry is a description of the methods of reproduction, seed dispersal, germination requirements and conditions, seed survival and longevity, early establishment characteristics and requirements, cultural practices and management options that have proven effective or ineffective in controlling infestations, and a notation of the species' inclusion on federal or state noxious weed lists.

Book Description
This book might be called a Who's Who among Weeds as it covers 102 of the most common weeds found throughout the United States. Weeds of lawn and yard, weeds that are sometimes used for food, weeds that are the bane of hayfever sufferers, weeds that can ruin cow's milk, poisonous weeds, and even the real desperadoes that can totally overtake a field in one season are all covered. The author, Edwin R. Spencer, was a farmer and biology professor; his text is both a practical and an authoritative guide to weeds, able to speak to nature lovers, farmers, and scientists alike. Pigweed … Dogbane … Carpet Weed … Crab Grass … Wild Garlic … Spiderwort … Chicory … Ragweed … Poison Ivy … Yellow Dock … each weed is listed under its most common name, but since one man's Moneywort is another man's Creeping Jenny, its scientific and alternative common names are also given. Then follows a delightful description of each weed, full of information and good humor as well. Details for controlling the weed are given in this section. To aid in identification each weed is multiply keyed at the front of the text as to its place and season of growth, the type of soil it prefers, and physical characteristics. Even if you know nothing about botany, you will most likely be able to identify your find through these keys or just by flipping through the 102 first-rate illustrations. To the gardener and farmer weeds are something to be hoed out and plowed under, but weeds are also a fascinating group of plants, as this thoroughly readable book will point out. They are the plants you are most likely to come upon in nature jaunts and the ones you are going to have to come to terms with if you do any gardening of your own. "A most fascinating book." — Garden Club of America.

Book Description
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
