Plant Pathology presents information and advances in plant pathology including disease induction and development and disease resistance and control. This book is organized into two major parts encompassing 14 chapters that focus on diseases, pathogenicity, and pathogen variability. The first part of the book deals with general considerations of disease, the disease cycle, parasitism and pathogenicity, and the variability in pathogens. This is followed by a presentation of the mechanisms by which pathogens cause disease and plants resist disease. Core chapters focus on the effects of pathogen-produced enzymes, toxins, growth regulators, and polysaccharides on the structural organization and on the basic physiological processes of photosynthesis, translocation, and respiration. The chapters also discuss the defense mechanisms of the plant. Moreover, this book explains the genetics of host-parasite interaction, effects of environment on disease development, and control. The second part of the book deals with the infectious diseases caused by fungi, bacteria, parasitic higher plants, viruses, and nematodes. This part also looks into the noninfectious diseases caused by environmental factors. The diseases caused by each type of pathogen are discussed comprehensively as a group and are subsequently discussed individually in detail. This book includes diagrams of cycles for each disease to create visual images for better understanding of the disease and message retention. This book is ideal for students with introductory course in plant pathology.
In the much anticipated 3rd edition of Grape Pest Management, more than 70 research scientists, cooperative extension advisors and specialists, growers, and pest control advisers have consolidated the latest scientific studies and research into one handy reference. The result is a comprehensive, easy-to-read pest management tool. The new edition, the first in over a decade, includes several new invasive species that are now major pests. It also reflects an improved understanding among researchers, farmers, and growers about the biology of pests. With nine expansive chapters, helpful, colorful photos throughout, here’s more of what you’ll find: •Diagnostic techniques for identifying vineyard problems •Detailed descriptions of more than a dozen diseases •Comprehensive, illustrated listings of insect and mite pests,including the recently emerging glassy winged sharpshooter and Virginia creeper leaf-hopper •Regional calendars of events for viticultural management •Up-to-date strategies for vegetation management
"There is nothing in the world like this book. It should be in every library and on the bookshelves of all those interested in cacti. The book will be an important resource for plant physiology, agronomy, and horticulture classes at both the undergraduate and graduate level."—Bruce Smith, Brigham Young University "Cacti: Biology and Uses is a landmark publication of one of the world's most unique group of plants. Park Nobel, a leading authority on succulent plants, has assembled a collection of contributions that spans a wide range of issues extending from basic systematics, anatomy, physiology and ecology to considerations of conservation and human uses of this diverse group of plants. This nicely-produced and well-illustrated volume provides a resource that will be of great use to a wide range of scientists, practitioners, and enthusiasts of this plant group."—Harold Mooney, Paul S. Achilles Professor of Environmental Biology, Stanford University
Food security has been and always will be a human concern. Food security has always been fragile, threatened by a variety of factors including plant disease epidemics. Several plant disease epidemics of the past lead to questions like: What happened? How did people deal with these epidemics? What were the social and political consequences? This volume deals with such questions in six selected chapters. Chapter 1 discusses black stem rust of wheat in antiquity, and how its epidemics were perceived by the ancients. Chapter 2 reconstructs a forgotten epidemic of yellow stripe rust, 1846, on rye, a staple food in Continental Europe. Chapter 3 describes the epidemics of potato late blight in Continental Europe, 1844-46, that caused the Continental Famine and - in the longer reach - contributed to the European revolutions of 1848. Chapter 4 studies the impact of plant disease on the food situation in the neutral Netherlands during World War I. Chapter 5 looks at belligerent Germany during World War I, ravaged by plant disease. Chapter 6 treats the problem of under-rating and over-estimating the effect of plant diseases on the course of history: the effects of ergot on political events in Russia, 1722, and in France, 1779, of black stem rust on wheat on the Russian Famine, 1932/3, and of rice brown spot on the Bengal Famine, 1943. This publication is of interest to plant pathologists, historians, economists and sociologists, interested in history, and with a focus on food.

Excerpt from Howrah The deep channel alternates from left to right and vice cersa according to the windings of the river, except where deflected by the large tributaries which debouch into it at the southern limit of this district. Proceeding from Howrah Bridge, the deep channel runs on the Calcutta side in the Calcutta Reach past the Fort and Kidderpore to Garden Reach. At Rajganj, Opposite Hangman Point, it crosses over to the Howrah Side, and follows the Sankrail Reach as far as Melancholy (menikhali) Point. It then zigzags from left to right at each bend.

The California Naturalist Handbook provides a fun, science-based introduction to California’s natural history with an emphasis on observation, discovery, communication, stewardship and conservation. It is a hands-on guide to learning about the natural environment of California. Subjects covered include California natural history and geology, native plants and animals, California’s freshwater resources and ecosystems, forest and rangeland resources, conservation biology, and the effects of global warming on California’s natural communities. The Handbook also discusses how to create and use a field notebook, natural resource interpretation, citizen science, and collaborative conservation and serves as the primary text for the California Naturalist Program.
