Molecular Biology of Weed Control by Jonathan Gressel Pdf

"Weeds are rarely considered a priority despite the fact that all active farmers know that the majority of their variable costs and time are devoted to eradicating them. Even most crop losses due to pests can be traced directly back to weeds, which harbor the pests as secondary hosts. In the Molecular Biology of Weed Control, Jonathan Gressel focuses attention upon the tools of molecular biology that can be used effectively in the science of weed control. Always keeping his perspective congruent with that of the working farmer, Gressel explains how weed biologists and ecologists are beginning to use recently developed tools to control intransigent weed species in modern as well as less developed areas of the world. With his usual candor, Gressel evaluates past efforts, while also exploring future prospects for replacing chemical herbicides with genetic engineering, to improve a crop's ability to compete against its feral cousins for light, nutrients, and water. Like much of Gressel's work, this book should be mandatory reading for all agriculturists and plant scientists, so that they employ and encourage what is truly effective and efficient in meeting one of this century's most critical challenges: maximizing agricultural productivity.

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.

Herbicide Activity by R. Michael Roe,James Dale Burton,Ronald J. Kuhr Pdf

Developments in the understanding of herbicide activity and toxicology have expanded tremendously in the past fifteen years. Research on the mechanism of action of most major classes of herbicide chemistry has provided scientists with excellent insight into enzyme targets. More recently, developments in molecular biology have provided information about herbicide action at the genetic level. Less well understood are the toxicological aspects of herbicide activity that culminate in plant injury or death. Toxicology, Biochemistry and Molecular Biology of Herbicide Activity is a review of the recent literature on most of the major classes of herbicide chemistry in commercial use. The chapters include information about different aspects of herbicide activity related to photosynthesis, inhibition of amino acid biosynthesis, disruption of cell division and microtubule assembly, activity of phytohormone (auxin) mimics, inhibition of fatty acid biosynthesis and some developments in the understanding of herbicide resistance.

Molecular Mechanisms of Herbicide Selectivity by D. E. Hathway Pdf

Because plants of different species vary in the way in which they take up, transport, and metabolize chemicals in the soil, selective herbicides can be synthesized. This book examines those aspects of plant physiology, principally in crop plants, which can be affected by herbicides; the possibilities that are offered by recombinant DNA technology for developing resistance to herbicides; and methods for exploiting or preventing acquired tolerance. The author also covers recent work on ultra-selective mycoherbicides and the use of allelochemicals as herbicide substitutes.

Weed and Pest Control by Ilias S. Travlos,Dimitrios Bilalis,Demosthenis Chachalis Pdf

In this book, current research is presented no the study of weed and pest control with a special focus on molecular biology, agronomic practices and environmental impact. Topics discussed include integrated weed management in winter cereals; control of Orobanche spp. in terms of molecular aspects and agronomic practices; alien plant species invading rare and protected habitats; "belowground" seedbank processes as alternative non-chemical options for weed control; glyphosate-resistant volunteer maize (Zea mays L.) and its impact and management; the case of several Fabaceae weeds in terms of their tolerance to glyphosate and its mechanisms; the case of the invasive pest Phyllocnistis citrella and some proposed control strategies; pollen provisioning for the conservation of omnivorous phytoseiids: an integrated approach for pest control in protected cropping systems, vineyards and orchards; aphidophagous ladybird beetles as biological control agents and the use of Bacillus spp. as a biocontrol agent. By means of the above mentioned chapters, it is shown how management of several noxious weeds and pests should be achieved, relies on the several achievements of molecular biology and minimises the negative environmental effects of a sole and non-orthologic chemical control. Integrated management of weeds and pests gives the opportunity to significantly reduce the use of pesticides by utilising a variety of methods, including cultural, biological and structural strategies to control a multitude of weed and pest problems, and keep them from becoming a problem.

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

Non-Chemical Weed Control by Khawar Jabran,Bhagirath S. Chauhan Pdf

Non-Chemical Weed Control is the first book to present an overview of plant crop protection against non-food plants using non-chemical means. Plants growing wild—particularly unwanted plants found in cultivated ground to the exclusion of the desired crop—have been treated with herbicides and chemical treatments in the past. As concern over environmental, food and consumer safety increases, research has turned to alternatives, including the use of cover crops, thermal treatments and biotechnology to reduce and eliminate unwanted plants. This book provides insight into existing and emerging alternative crop protection methods and includes lessons learned from past methodologies. As crop production resources decline while consumer concerns over safety increase, the effective control of weeds is imperative to insure the maximum possible levels of soil, sunlight and nutrients reach the crop plants. Allows reader to identify the most appropriate solution based on their individual use or case Provides researchers, students and growers with current concepts regarding the use of modern, environment-friendly weed control techniques Presents methods of weed management—an important part of integrated weed management in the future Exploits the knowledge gained from past sustainable weed management efforts

Biological Approaches for Controlling Weeds by Ramalingam Radhakrishnan Pdf

Weed populations in agriculture are a major cause of yield loss. Conventionally, crop rotation and tillage practices limit the number of weed flora. Several chemical herbicides are being applied to control weed growth, but the long-term use of those chemicals does not effectively control weeds, due to the development of resistant germplasms, which cause hazardous effects in living organisms. The global interest in organic farming endorses the alternative way of weed control against chemical herbicides. Recently, biological agents have been added to integrated weed management strategies. Several studies reveal that plant extracts, bacteria, fungi and their products effectively control weed seed germination and growth. The aim of this book is to discuss the current understanding of bioherbicides and strategies to weed control.
