Book Description
Nature has gone feral. How can we re-attune ourselves to the new nature? A field guide can help. Human action has transformed our planet and ushered in a new geological epoch—the Anthropocene. The effects are global in scope, but take shape within distinct social and ecological "patches," discontinuous regions within which the key actors may not be human, but the plants, animals, fungi, viruses, plastics, and chemicals creating our new world. Field Guide to the Patchy Anthropocene takes stock of our current planetary crisis, leading readers through a series of sites, thought experiments, and genre-stretching descriptive practices to nurture a revitalized natural history. Field guides teach us how to notice, name, and so better appreciate more-than-human worlds. They hone our powers of observation and teach us to see the world anew. Field-based observations and place-based knowledge cultivation—getting up-close and personal with patchy dynamics—are vital to truly grapple with the ecological challenges and the historical conjunctures that are bringing us to multiple catastrophic tipping points. How has commercial agriculture runoff given rise to comb jellies in the Black Sea? What role did the Atlantic slave trade play in the worldwide spread of virus-carrying mosquitoes? How did the green revolution transform the brown planthopper into a superpredator in Philippine rice fields? Questions like these open up new ways of understanding, and ways of living through, the epoch that human activity has ushered in. This Field Guide shifts attention away from knowledge extractive practices of globalization to encourage skilled observers of many stripes to pursue their commitments to place, social justice, and multispecies community. It is through attention to the beings, places, ecologies, and histories of the Anthropocene that we can reignite curiosity, wonder, and care for our damaged planet.

Book Description
Pest and Disease Management Handbook updates the 3rd edition of the Pest and Disease Control Handbook (1989). The structure of this important new book differs in several respects, acknowledging the advances that have been made in integrated crop management and the trends towards the more rational use of pesticides. Fully revised and up-to-date, the book commences with a new introductory chapter covering the principles of pest and disease management. Following chapters, each written by acknowledged experts in the field, cover a group of major temperate northern hemisphere crops. As well as comprehensive details of pest and disease management strategies, each chapter also includes a classification scheme for the cited pests and diseases. This important publication is a vital tool for all those involved in the crop protection / agrochemical industry including business managers, entomologists, agricultural scientists, plant pathologists and those studying and teaching BASIS courses. As an important reference guide for undergraduate and postgraduate students studying agricultural sciences, applied entomology and crop protection, copies of the book should be available on the shelves of all research establishments and universities where these subjects are studied and taught. Pest and Disease Management Handbook is published for the British Crop Protection Council (BCPC) by Blackwell Science. BCPC is a registered charity having the principal objective of promoting the development, use and understanding of effective and sustainable crop protection practice. Dr David V Alford, based in Cambridge, UK, is a member of the BCPC board, with many years' experience working as a government entomologist.

Book Description
Nutrient imbalance in soils is an emerging threat to sustainable agriculture: intensive cultivation, use of poor quality groundwater, depletion of soil organic matter and excessive use of fertilizers are major reasons for poor soil fertility worldwide. This necessitates correct diagnosis of plant nutrient deficiencies to avoid further use of pesticides in cases where pests or pathogens that are not in fact the cause of poor crop health. Richly illustrated with 600 colour photographs, this book is a visual field identification guide for symptoms of most common nutrient deficiencies in field crops, covering all their stages of occurrence. Detailed descriptions and suggested for management practices are given with each entry.
