Available in PDF, EPUB and Kindle. Book excerpt: There is growing concern among scientists, farmers and the general public that pesticides are being applied ever more widely but with less and less discretion. This book brings together a range of experts to discuss how crop protection chemicals can be used more rationally, so as to maximise benefits in yield and quality while minimising environmental and economic costs. The book is based on the ninth Long Ashton Symposium and is organised into four sections. The first, environment, examines to what extent current pesticide use is affecting the environment and human welfare, and what changes in practice are justified. The second, application, assesses progress in performance and safety in the use of pesticides, while the next section, resistance, looks at problems and shortcomings arising from the appearance of resistant strains of pests, and considers strategies for surmounting these difficulties. The final section, forecast and pest management, asks whether existing methods of assessing risks are acceptable and seeks ways of rending decision making in crop protection more rational.

Available in PDF, EPUB and Kindle. Book excerpt: This monumental work by the world's preeminent authority on Arctic floras--the first comprehensive, up-to-date botanic manual for this region--is the product of the author's more than forty years of study of circumpolar floras. The book describes and illustrates all flowering plants and vascular cryptograms known to occur in Alaska, the Yukon, the Mackenzie District, and the eastern extremity of Siberia. Some 1,974 taxa, belonging to 1,559 species, occur in this region; all are described. For 1,735 of these, the book provides detailed description, nomenclature, plant drawing, and range maps. In each case, one map gives distribution in the Alaskan region; a second, on circumpolar projection, gives worldwide range. This volume is the first major flora to assemble such comprehensive range data and to provide such maps. An analytic key to all species described is provided for each genus, and there is an artificial key to families. An Introduction describes the past and present climatic, geologic, and ecologic character of the regions covered, the history of botanical collection in these regions, and the book's treatment of botanical and taxonomic details; and lists the plants of neighboring regions likely to occur. Glossary, plant authors' list, bibliography, and indexes are provided. The superb drawings were prepared by Dagny Tande-Lid, and eight pages of illustration in color are included.

This book was released on 2002 with total page 583 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the biological control programmes in Canada since 1981. The book includes three chapters on the relationships of invasive species, pesticides and taxonomy to biological control, and contains sections on insects and mites (55 chapters, including crop pests, forest pests, public health pests and livestock pests), weeds (25 chapters), and pathogens (19 chapters). Some emphasis is given on pathogens and nematodes either as targets for control or as biological control agents acting directly as hyperparasites or pathogens, or indirectly as antagonists competing successfully for the same resources as the target pest. Appendices provide details of noteworthy publications on biological control from 1981-2000 and Canadian suppliers of biological control organisms .

Available in PDF, EPUB and Kindle. Book excerpt: Biological control of weeds has been practised for over 100 years and Australia has been a leader in this weed management technique. The classical example of control of prickly pears in Australia by the cactus moth Cactoblastis cactorum, which was imported from the Americas, helped to set the future for biocontrol of weeds in many countries. Since then there have been many projects using Classical Biological Control to manage numerous weed species, many of which have been successful. Importantly, there have been no serious negative non-target impacts – the technique, when practised as it is in Australia, is safe and environmentally friendly. Economic assessments have shown that biocontrol of weeds in Australia has provided exceedingly high benefit-to-cost ratios. This book reviews biological control of weeds in Australia to 2011, covering over 90 weed species and a multitude of biological control agents and potential agents. Each chapter has been written by practising biological control of weeds researchers and provides details of the weed, the history of its biological control, exploration for agents, potential agents studied and agents released and the outcomes of those releases. Many weeds were successfully controlled, some were not, many projects are still underway, some have just begun, however all are reported in detail in this book. Biological Control of Weeds in Australia will provide invaluable information for biological control researchers in Australia and elsewhere. Agents used in Australia could be of immense value to other countries that suffer from the same weeds as Australia. The studies reported here provide direction to future research and provide examples and knowledge for researchers and students.

Book excerpt: A much-needed new study on plant galls growths on plants formed of plant tissue that are caused by other organisms. Most naturalists have come across oak apples, robin s pincushions, marble galls and witches brooms, a few of the more familiar examples of the strange growths that are plant galls. They are beautiful, often bizarre and colourful, and amazingly diverse in structure and in the organisms which cause them. They have been known since ancient times and have attracted superstitions and folk customs. Both the ancient Greeks and the Chinese used them in herbal medicine, and until well into the nineteenth century, they had a variety of commercial uses: important for dyeing cloth, tanning leather and for making ink. Knowledge of gall types increased during the late nineteenth century and throughout the twentieth century as more species were described and their structure became more clearly understood, and yet even today, little is known about the mechanisms that cause gall formation as well as the life cycles of the organisms that initiate gall growth. Since most galls do not cause any economic damage to crop plants, research funding has traditionally been sparse in this area. However, the insect cycles and gall structures are amazing examples of the complexity of nature. Margaret Redfern explores these fascinating complexities in this latest New Naturalist volume, providing much-needed insight into the variety of galls of different types caused by a wide range of organisms including fungi, insects and mites. She discusses the ecology of galls more generally and focuses on communities of organisms within galls, the evolution and distribution of galls, as well as human and historical perspectives."

Our understanding of the ecological and evolutionary processes underlying these effects has until now been limited, and experimental methods are sometimes lacking.This book presents the key papers form the first International Organization for Biological Control global symposium, held in Montpellier, France in October 1999. It addresses the issues and concerns involved in biological control, and assesses the current status of evaluation of the ecologicaleffects.

Available in PDF, EPUB and Kindle. Book excerpt: Undesirable invasive plants are infesting public and private lands in this country at an alarming rate. These nonnative species destroy native habitats, threaten endangered plants and animals, interfere with recreation and transportation, and cause economic losses as land values and productivity decline. Various methods are used to suppress invasive plants, from herbicides to burning to cultivation. Classic biological control--in which selected host-specific, plant-attacking insects, mites, nematodes, and pathogens are introduced from the invasive plant's native lands--provides an additional tool for land managers to reduce invasive plant populations. In this volume, leading experts review the discipline of biological control of invasive terrestrial and aquatic plants. Topics addressed include the ecology and economics of biological control, monitoring, non-target impacts, a Code of Best Practices, and the processes of identifying, introducing, distributing, and maintaining biological control agents. In addition to chapters on the theory and practice of biological control, this book provides information about 39 target plants in the continental United States and 94 agents, including their origin, biology, habitat, impacts, and distribution. More than 300 color photographs help identify the plants and agents. The book concludes with information about invasive plants that are targeted for biological control in the future. An invaluable reference for land managers, natural resource and weed control specialists, and students of natural resource management, Biological Control of Invasive Plants in the United States provides practical, science-based information needed for understanding andusing biological control as part of an integrated invasive-plant management strategy.
