Download or read book Weed Biology and Management written by Inderjit and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 550 pages. 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 Environmental Impact of Genetically Modified Crops written by Natalie Ferry and published by CABI. This book was released on 2009 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genetic modification of crops continues to be the subject of intense debate, and opinions are often strongly polarised. Environmental Impact of Genetically Modified Crops addresses the major concerns of scientists, policy makers, environmental lobby groups and the general public regarding this controversial issue, from an editorially neutral standpoint. Included is a chapter by Bruce Tabashnik on the recent discovery of the first documented case of field-evolved resistance to a crop genetically modified to carry the gene for the Bacillus thuringiensis toxin. While the main focus is on environmental impact, food safety issues for both humans and animals are also considered. The book concludes with a discussion on the future of agricultural biotechnology in the context of sustainability, natural resource management and future global population and food supply.

Download or read book Postharvest Pathogens and Disease Management written by P. Narayanasamy and published by John Wiley & Sons. This book was released on 2005-12-07 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: POSTHARVEST PATHOGENS AND DISEASE MANAGEMENT Postharvest diseases caused by microbial pathogens account for millions of dollars in losses of both durable and perishable produce products every year. Moreover, with consumers increasingly demanding minimally processed vegetables and fruits--which can be invaded by human pathogens--there is an imperative need for suitable protective measures to provide pathogen-free commodities that are free from, or contain only acceptable levels of, chemical residues. Providing details of both conventional and modern molecular techniques applicable for the detection, identification, and differentiation of field and storage microbial pathogens, Postharvest Pathogens and Disease Management: * Discusses diseases of both durables and perishables during transit and storage * Provides a basic understanding of the effects of handling and storage practices as well as field conditions and product susceptibility on the development of postharvest diseases * Reveals, as a cautionary note, the potential hazards of mycotoxins with carcinogenic properties that can contaminate fruits and vegetables * Contains detailed information derived from elucidative evidence and disease data in order to explain the infection process and subsequent stages of disease development * Helps readers to avoid conditions that favor disease incidence and spread * Includes real life examples of disease management strategies to help readers develop effective disease management systems suitable for different ecosystems * Emphasizes the importance of integrating several different effective methods in tandem, including the development of cultivars with resistance to postharvest diseases; the selection of suitable analytical methods; and the effective use of biocontrol agents and chemicals * Presents protocols for numerous techniques and basic methods, making the book a distinctive and highly useful teaching and research tool Postharvest Pathogens and Disease Management offers readers insight into the principles and methods of avoiding and managing postharvest diseases of fruit and vegetable products in an efficient, economical, and environmentally feasible manner, allowing producers to sell safer, higher-quality produce to the public and prevent the losses associated with postharvest disease.

Download or read book Developments in Fungal Biology and Applied Mycology written by Tulasi Satyanarayana and published by Springer. This book was released on 2017-12-29 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the developments in important aspects of fungi related to the environment, industrial mycology, microbiology, biotechnology, and agriculture. It discusses at length both basic and applied aspects of fungi and provides up-to-date laboratory-based data. Of the estimated three million species of fungi on Earth, according to Hawksworth and coworkers, more than 100,000 have been described to date. Many fungi produce toxins, organic acids, antibiotics and other secondary metabolites, and are sources of useful biocatalysts such as cellulases, xylanases, proteases and pectinases, to mention a few. They can also cause diseases in animals as well as plants and many are able to break down complex organic molecules such as lignin and pollutants like xenobiotics, petroleum and polycyclic aromatic compounds. Current research on mushrooms focuses on their hypoglycemic, anti-cancer, anti-pathogenic and immunity-enhancing activities. This ready-reference resource on various aspects of fungi is intended for graduate and post-graduate students as well as researchers in life sciences, microbiology, botany, environmental sciences and biotechnology.
