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.

Book Description
The strength of this book is that it is written by someone who has spent a lifetime devoted to the science of economic botany. The author has brought together his vast experience in the field in Africa with his studies of arid land plants at the Royal Botanic Gardens, Kew. The result is an informative and reliable text that covers a vast range of topics. It is also firmly based upon the author's research and interest in plant taxonomy and therefore fully acknowledges the importance of correct naming and classification in the field of science of economic botany. The coverage is of economic botany in its broadest sense. I was delighted to find such topics as ecophysiology, plant breeding, the environment and conservation are included in the text. This gives the book a much more comprehensive coverage than most other texts on the subject. I was also glad to see that the book covers the use of various organisms that are no longer considered part of the plant kingdom such as various species of fungi and algae. It is indeed a broad ranging book that will be of use to many people interested in the uses of plants and fungi. Economic botany is once again being given more prominence as a discipline because of its enormous relevance to both conservation and sustainable development. Those people involved in those topics shOUld find this a most useful resource.
