Available in PDF, EPUB and Kindle. Book excerpt: Excessive weed growth is one of the most serious problems facing farmers throughout the tropics. There is a need for professionally trained weed scientists to become involved in research at the highest level, where existing technologies can be further developed and new ones generated.

Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Tropical Grassy Weeds written by F. W. G. Baker and published by Cab Publishing. This book was released on 1991 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weeds are the cause of great losses to crop production in the tropics and grassy weeds present a particular problem because of their similarity to cereal crop plants. It is therefore difficult to devise control methods and management practices appropriate for such weeds. This book reviews our current knowledge of this subject and is the outcome of a workshop on integrated control of grassy weeds in tropical subsistence farming systems, held in Nairobi in February 1990. The workshop was organised by CASAFA (Commission on the Application of Science to Agriculture, Forestry and Aquaculture) of the International Council of Scientific Unions. The contents include a general review of grassy weeds, their physiology in tropical agriculture, management by biological and chemical control, integrated weed management, control in tropical cereals, in tropical grasslands and forage crops, in mixed crops and in upland rice, and overviews of grassy weeds in Kenya, the Phillipines and Australia.
