Book Description
Weeds are variously defined as plants growing where they are not wanted, plants that interfere with human activity. Weeds affect everyone in the world by reducing crop yield and quality, delaying or interfering with harvesting, interfering with animal feeding, reducing animal health, preventing water flow, as plant parasites, etc. It is estimated that those problems cause $ billions worth of crop losses annually and the global cost of controlling weeds also runs into many $ billions every year. Atlas of Weed Mapping presents an introductory overview on the occurrence of the most common weeds of the world. The book notably includes: Description of cropping practices and explanations for the global distribution of weeds Invasive plant mapping Aquatics and wetland plants with histological plant details Theoretical and practical aspects of weed mapping Aspects on the documentation of herbicide resistance Biodiversity, rare weeds and the dominance of the most common weeds Fully illustrated with more than 800 coloured figures and a number of tables, this new characterisation of anthropogenic vegetation will be interesting for readers of a great number of disciplines such as agriculture, botany, ecology, geobotany and plant community research. More than a hundred experts have contributed data to this unique compilation.

Book Description
Erstmals wird hier die Fulle der englischsprachigen Athiopienliteratur geordnet dargeboten. In 100 Sections fuhrt der Autor alle fur die wissenschaftliche Beschaftigung mit Athiopien wichtigen Buch- und Zeitschriftenbeitrage zum Beispiel zur "Historyof Research", "Archaeology", "Religion", aber auch Fragen der "Sociology", "Agriculture", "Zoology" und "Medical Sciences" auf. Wie im Falle der deutschsprachigen Literatur ("Bibliographia Aethiopica: Die athiopienkundliche Literatur des deutschsprachigenRaumes" = Aethiopistische Forschungen 9 [1982]) berucksichtigt der Autor auch alle ihm zuganglichen Besprechungen, womit bei einer Aufnahme von mehr als 24.000 Titeln eine Art "Bibliographic Enzyclopedia" entstanden ist.

Book Description
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.
