Book Description
For each of the important weed species we have attempted in these pages to present a summary of the world distribution, the known biology, and the agricultural importance. A line drawing and a description is included for each species, as well as a list of common names used in the countries where the weed is troublesome.

Book Description
In 1990, while Vince Smith was working as a senior keeper at Chester Zoo, a newborn chimpanzee in his care was abandoned by her mother. Named Sophie, the baby chimp was taken home and hand-reared by Vince and his wife. Six months later another new baby arrived: Oliver, their son.

Book Description
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. In order to recognize thetrue magnitude of the weed problem, and to be better equipped todesign effective weed control methods, it is vital to identify andlearn as much as possible about the many different species of thisdestructive agricultural predator. The culmination of four decades of global research, World Weedspresents comprehensive and up-to-date information on over 100weeds--addressing recent changes in such areas as crop tillagemethods, herbicide use, and agricultural runoff. This monumentalwork, featuring a wealth of original data from the authors,provides extensive coverage of the known biology of each species.Each entry contains a full botanical description, plus importantdetails on habitat requirements and distribution, seed production,ecology, physiology, crop impact, and more. Generously suppliedwith dozens of unique illustrations and species distribution mapscovering over 100 countries, this definitive resource boasts anextensive multilingual index of common names, and a massivebibliography with over 3,000 references to facilitate furtherreading and research. World Weeds is a truly masterful referencethat will be celebrated by weed and crop scientists, botanists, andothers for years to come.

Book Description
Weeds are the main biological constraint to crop production throughout the year. Uncontrolled weeds could cause 100% yield loss. In Australia, the overall cost of weeds to Australian grain growers was estimated at AU$ 3.3 billion annually. In terms of yield losses, weeds amounted to 2.7 million tonnes of grains at a national level. In the USA, weeds cost US$ 33 billion in lost crop production annually. In India, these costs were estimated to be much higher (US$ 11 billion). These studies from different economies suggest that weeds cause substantial yield and economic loss. Biology and Management of Problematic Weed Species details the biology of key weed species, providing vital information on seed germination and production, as well as factors affecting weed growth. These species include Chenopodium album, Chloris truncata and C. virgate, Conyza bonariensis and C. canadensis, Cyperus rotundus, and many more. This information is crucial for researchers and growers to develop integrated weed management (IWM) strategies. Written by leading experts across the globe, this book is an essential read to plant biologists and ecologists, crop scientists, and students and researchers interested in weed science. - Provides detailed information on the biology of different key weed species - Covers weed seed germination and emergence - Presents the factors affecting weed growth and seed production

Book Description
Here is a vital new source of "need-to-know" information for cotton industry professionals. Unlike other references that focus solely on growing the crop, this book also emphasizes the cotton industry as a whole, and includes material on the nature of cotton fibers and their processing; cotton standards and classification; and marketing strategies.

Book Description
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.
