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.
Integrating New Technologies for Striga Control

Witchweeds (Striga species) decimate agriculture in much of Africa and parts of Asia, attacking the major cereal grains and legumes, and halving the already very low yields of subsistence farmers. Several years of research have provided promising technologies, based on the fundamental biology of the parasite?host associations, for dealing with this scourge. However, there is an apparent realization that these technologies will fail because highly successful weeds such as Striga evolve resistance to all types of controls unless proven methods are integrated with each other for a more sustainable solution.Integration is often an anathema to basic scientists who typically deal with single variables and solutions. However, key leaders in the development of the new knowledge-based control strategies, already in the field and under development, recently joined forces to develop strategies and projects in order to integrate the technologies in a symposium in Ethiopia in November 2006. The encouraging results are described in this peer-reviewed book, authored by leaders in the field who have been supplying the basic biology, genetics, biochemistry, and molecular information that have offered insights and generated technologies in how to deal with Striga.

Plant Hormones: Biosynthesis and Mechanisms of Action is based on research funded by the Chinese government's National Natural Science Foundation of China (NSFC). This book brings a fresh understanding of hormone biology, particularly molecular mechanisms driving plant hormone actions. With growing understanding of hormone biology comes new outlooks on how mankind values and utilizes the built-in potential of plants for improvement of crops in an environmentally friendly and sustainable manner. This book is a comprehensive description of all major plant hormones: how they are synthesized and catabolized; how they are perceived by plant cells; how they trigger signal transduction; how they regulate gene expression; how they regulate plant growth, development and defense responses; and how we measure plant hormones. This is an exciting time for researchers interested in plant hormones. Plants rely on a diverse set of small molecule hormones to regulate every aspect of their biological processes including development, growth, and adaptation. Since the discovery of the first plant hormone auxin, hormones have always been the frontiers of plant biology. Although the physiological functions of most plant hormones have been studied for decades, the last 15 to 20 years have seen a dramatic progress in our understanding of the molecular mechanisms of hormone actions. The publication of the whole genome sequences of the model systems of Arabidopsis and rice, together with the advent of multidisciplinary approaches has opened the door to successful experimentation on plant hormone actions. - Offers a comprehensive description of all major plant hormones including the recently discovered strigolactones and several peptide hormones - Contains a chapter describing how plant hormones regulate stem cells - Offers a fresh understanding of hormone biology, particularly molecular mechanisms driving plant hormone actions - Discusses the built-in potential of plants for improvement of crops in an environmentally friendly and sustainable manner

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.

Invasions of non-native plants into forests of the Southern United States continue to go unchecked and only partially un-monitored. These infestations increasingly erode forest productivity, hindering forest use and management activities, and degrading diversity and wildlife habitat. Often called non-native, exotic, non-indigenous, alien, or noxious weeds, they occur as trees, shrubs, vines, grasses, ferns, and forbs. This guide provides information on accurate identification of the 56 non-native plants and groups that are currently invading the forests of the 13 Southern States. In additin, it lists other non-native plants of growing concern. Illustrations. This is a print on demand edition of an important, hard-to-find publication.

Parasitic flowering plants are strikingly impressive and beautiful and hold many surprises of both general and scientific interest. Parasites also have great influence on the quality of human life when attacking crop plants. Some parasites have since early times appealed to our imagination and have been part of religious or folkloristic events and used as gifts to royalties. This beautifully illustrated book covers all parasitic families and most of the genera. It also discusses the establishment of the parasite, the structure and function of the nutrient absorption organ (haustorium), and how the parasites are pollinated and dispersed as well as their ecology, hosts, and evolution. The book is written in a mostly non-technical language and is provided with a glossary and explanatory boxes. For additional information about this book, including some sample photographs, as well as a list of corrections that have been incorporated in the 2011 reprint, please visit the author's web site. Parasitic Flowering Plants was nominated by The Council on Botanical and Horticultural Libraries for the 2010 Annual Award for a Significant Work in Botanical or Horticular Literature, in the category ‘Technical Interest’.
