Book Description
Parasitic weeds of the families Cuscutaceae, Orobanchaceae and Scrophulariaceae are considered to be among the major problems facing agriculture in the Tropics and Subtropics. In the last decades, enormous efforts have been made and success achieved by scientists all over the world in gaining a better understanding of their biology and ecology as well as of control methods. However, no substantial reduction of infestation has been achieved in the past and control strategies specific to the different parasites, crops and farming systems must be further developed or adapted and realised among a wider farming population with suitable extension methods. This `Technical Manual' provides up-to-date methodologies for various aspects of research and extension related to parasitic weed species of the genera Striga, Alectra, Orobanche and Cuscuta. It has the intention to support scientists and extension workers of international and national research and extension institutes and universities, who are either new to the subject or plan to apply further techniques they are not yet familiar with.

Book Description
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.

Book Description
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.

Book Description
This book was written in response to significant recent advances in understanding the mechanisms of parasitism in the Orobanchaceae, and breakthroughs in the control of the parasitic weeds Striga and Orobanche. It consists of 26 contributions by internationally recognized leading scientists. The main book chapters are grouped into two parts: · Part I – The Orobanchaceae and Their Parasitic Mechanisms · Part II – The Weedy Orobanchaceae and Their Control The first part provides cutting-edge information on all key aspects of plant parasitism, such as the structure, development and function of the haustorium; nutrient transfer and the physiology of the parasite-host association; host reaction to parasitic plants; seed production and germination; the strigolactones and host-parasite signaling mechanisms; the parasite genome, phylogenetics, evolution and epigenetics; and ecology. Topics of the second part include: the problem posed by the weedy parasites; population diversity and dynamics; molecular diagnosis of seed banks; and detailed discussion of the various management strategies, including agronomic, chemical and biotechnological approaches, as well as host breeding for resistance, allelopathy and biological control. This book is intended for plant scientists, university lecturers and students, agronomists and weed specialists, breeders and farmers, extension personnel and experts in tropical and subtropical agriculture.

Book Description
Some animals and plants injure or kill millions of people annually, others cause trillions of dollars in property damage and loss. Such harmful species are understandably hated. However, the vast majority of the planet’s millions of species are disliked simply because of how they look and act. This bias is endangering numerous species that play important roles in maintaining both the natural ecosystems and the human economies of the world. In Defense of the World’s Most Despised Species examines the psychological motivations that lead people to make judgments about the attractiveness of species, noting the overwhelming importance of visual cues. It describes in considerable detail the physical and behavioral traits of species that lead us to love or hate them. Full color illustrations throughout present beautiful, charming animals and plants, species that seem loathsome, behavior of people in relation to such divergent species and their characteristics, and numerous explanatory diagrams of relevant biological and psychological phenomena. The aim of this book is to give readers insights into how we humans arrive at biased judgments and to promote the welfare of valuable, albeit sometimes unlovable animals and plants that consequently suffer from discrimination. Many of the ugliest, most disgusting, and feared species, such as vultures, toads, hyenas, sharks, spiders, and even the vast majority of cockroaches, in reality are some of our most valuable friends. Features Theme of the book – human preferences for and against species – is novel, scarcely examined to date. Multidisciplinary analysis, especially psychology, biological conservation science, and ecology, as well as philosophy, agriculture, urban planning, human health, and law. Text is accessible, user-friendly, concise, and well-organized, making numerous complex topics comprehensible, readable not only by specialists, but also by students and the educated layperson. Includes over 2,000 high-quality, entertaining, and informative color figures.

Book Description
Diseases constitute serious biotic constraints to sorghum production within West and Central Africa (WCA). Many of the diseases incited by fungi, bacteria, viruses and nematodes cause significant and economic losses. Further, sorghum production is constrained by water and nutrient stresses. This book describes the various biotic and abiotic constraints limiting sorghum production within WCA. Drawing heavily on research and development activities within the region, the book concentrates on the causal organisms identified, symptoms produced on sorghum and control measures. Various possibilities used in the control of all the diseases are described such as host plant resistance, cultural practices such as sanitation and planting date, and fungicidal use in seed treatment. A chapter of this book focuses on Striga hermonthica, a major root parasite of sorghum and other cereals in West and Central Africa. Methods involved in its control are described and novel approaches e.g. biological control that has recently received significant attention within the sub-region is highlighted. Further, extension approaches to Striga control are discussed. The book intends to contribute to a more meaningful and practical approach to research, development and control of diseases on sorghum in West and Central Africa.
