Biology and Management of Problematic Crop Weed Species by Bhagirath Chauhan Pdf

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

Weed Research by Paul E. Hatcher,Robert J. Froud-Williams Pdf

This book presents the most up-to-date and comprehensive guide to the current and potential future state of weed science and research. Weeds have a huge effect on the world by reducing crop yield and quality, delaying or interfering with harvesting, interfering with animal feeding (including poisoning), reducing animal health and preventing water flow. They are common across the world and cost billions of dollars’ worth of crop losses year on year, as well as billions of dollars in the annual expense of controlling them. An understanding of weeds is vital to their proper management and control, without which the reduction in crop yields that they would cause could lead to mass starvation across the globe. Topics covered include weed biology and ecology, control of weeds and particular issues faced in their control. Authored and edited by internationally renowned scientists in the field all of whom are actively involved in European Weed Research Society working groups, this succinct overview covers all the relevant aspects of the science of weeds. Weed Research: Expanding Horizons is the perfect resource for botanists, horticultural scientists, agronomists, weed scientists, plant protection specialists and agrochemical company personnel.

Weed Biology and Management by Inderjit Pdf

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.

Weeds and Their Ecological Functions by Alireza Taab Pdf

Weeds are problematic both in agricultural and nonagricultural areas so that they potentially cause economic losses. Weed interference in crops also date back to the beginning of agriculture and they have been able to persist, in spite of long term control operations. They are able to adapt and survive in the environment due to their specific characteristics. Thus, to control weeds efficiently knowledge of weed biology, in particular their survival mechanisms, ecological responses and interactions, is of important value in weed management systems. "Weeds and their Ecological Functions" provides information on weeds functional behaviors in their cultivations including weed seed dormancy, germination and seedling emergence, examples of beneficial and detrimental interactions between weeds and other organisms, weed behaviors in perennial crops and response of weeds to cover crops. This information is useful for students and weed scientists to analyze some of the functional behavior of weeds and to develop integrated weed management systems. Nowadays, there is a remarkable variability in environmental factors like temperature and precipitation because of climate changes around the globe. Weed and crop growth are substantially influenced by changes in the environment. Therefore, increased knowledge is needed to develop predictive tools to quantify the consequences of the changes. Moreover, weed control in the early stage of growth is of high importance. Factors regulating seedling emergence characteristics of the weeds in the field need to be well understood. The aspects of the seed dormancy system such as the effect of maternal environmental factors on primary dormancy, dormancy induction and dynamics, germinability and seedling emergence characteristics of weeds, are reviewed and discussed. Discussion is provided on the possible ecological and agricultural implications of weed seed ecophysiology. In addition, examples of seedling emergence behavior of summer and winter annual weed species are presented. Information is provided on the presence of some weeds in perennial crops that are not always harmful. Some weeds especially those characterized as perennial or invasive are highly competitive and could cause problems to the crops. However, the presence of some other weeds should be clearly reconsidered regarding their utility as cover species and their beneficial impacts. Such an approach could certainly maintain and enhance the profitability of sustainable agricultural systems like organic or low input agriculture. Cover cropping is a technique to improve soil fertility and to ensure yield stability. An overview is given on cover cropping typologies and their significance in different agricultural contexts, including their effects on physical and chemical soil characteristics, as well on the biocenotic components of the agroecosystems. The main characteristics of the better-suited species for cover cropping purposes are also reported. There are possible interactions between weeds and other organisms in the environment. To understand the role of weeds in agroecosystems, weed interactions with other biotic compartments including nematodes, plant pathogens, arthropod communities, and a crop are also presented.
