Westcott's Plant Disease is a reference book on diseases which attack plants. Diseases of plants are found on most all plants including trees, shrubs, grasses, forage, fruits, vegetables, garden and greenhouse plants as well as native wild flowers and even weeds. Plant Disease Handbook identifies various types of diseases which are known to invade these plants located throughout North and South America. The recordings include diseases caused by fungi, bacteria, viruses, viroids and nematodes. Causal disease agents are described and illustrated in many cases and diseases and disease control measures are also discussed. A book such as this is never finished since new reports of diseases are continuously reported. This includes new diseases and previously known diseases which occur on both presently recorded plants and on new plants found to be susceptible to diseases. Westcott's Plant Disease provides a reference and guide for identification and control of these plant disease problems.

This text reflects the immense current growth in interest in agroecology and changing approaches to it. While it is acknowledged that the science of ecology should be the basis of agroecological planning, many analysts have out-of-date ideas about contemporary ecology. Ecology has come a long way since the old days of "the balance of nature" and other romantic notions of how ecological systems function. In this context, the new science of complexity has become extremely important in the modern science of ecology. The problem is that it tends to be too mathematical and technical and thus off-putting for the average student of agroecology, especially those new to the subject. Therefore this book seeks to present ideas about ecological complexity with a minimum of formal mathematics. The book's organization consists of an introductory chapter, and a second chapter providing some of the background to basic ecological topics as they are relevant to agroecosystrems (e.g., soil biology and pest control). The core of the book consists of seven chapters on key intersecting themes of ecological complexity, including issues such as spatial patterns, network theory and tipping points, illustrated by examples from agroecology and agricultural systems from around the world.

The Use and Fate of Pesticides in Vegetable-based Agro-ecosystems in Ghana reviews current knowledge on pesticides use in vegetable farming in Ghana and establishes the fate of pesticides in situ in tropical vegetable-based agro-ecosystems as well as their environmental and public health impacts on selected population groups. A field survey showed that vegetable farmers often spray pesticides on prophylactic basis due to lack of information. Although some farmers may be aware of pesticide hazards, adequate protection is hardly taken to minimize risks. About 70% of exposed farmers had a reduction of 30% or more in whole blood acetylcholinesterase activity. About 95% of the farmers interviewed reported symptoms attributable to pesticide exposure. Water, waterbed sediment, and vegetable crops were checked for residues of the pesticides monitored on the farmers fields. Residues detected in water and waterbed sediment indicated that these have come from runoff from vegetable fields and that the measured levels were transient. Pesticide residue levels detected in five vegetable crop types (tomato, cabbage, pepper, onion, and eggplants) were correlated to the minimal risk levels (MRLs) set by the United States Agency for Toxic Substances and Disease Registry (ATSDR). Mean intakes of residues by 22- to 75-year old adult farmers were found to be low and did not seem to be associated with health risk. Data on persistent pesticide residues in farmers breast milk and blood serum indicated the presence of DDTs, dieldrin, HCB, and HCHs. When daily intakes of DDTs and HCHs to infants through breastfeeding were estimated, some farmers accumulated these compounds in breast milk above the threshold for adverse effects, which raise concerns on children health. Evidence was found for persistence of isomers of endosulfan and its sulfate metabolite in tomato cropped soil and plant tissues. However, the residue concentration in tomato fruits decreased to a level below the Codex MRL g

"Authors have made remarkable efforts to balance background with basic-applied research findings enhancing the understanding of the various issues and techniques involved in tomato production, physiology, breeding and genetics...It is a valuable resource of modern knowledge for research academics and graduate students, and also applicable to consultants and managers involved in tomato R&D, such as those in seed and chemical companies." Professor Daniel Leskovar in Chronica Horticulturae Tomatoes are the second most important vegetable crop in the world after potatoes. Originating in South America, they are now grown widely around the world. As the population continues to grow, there is a need to increase yields in the face of such challenges as climate change, threats from pests and diseases and the need to make cultivation more resource-efficient and sustainable. Drawing on an international range of expertise, this collection focuses on ways of improving the cultivation of tomatoes at each step in the value chain, from breeding to post-harvest storage. The book begins by looking at improvements in cultivation techniques, before moving on to review advances in ensuring genetic diversity, understanding of tomato physiology and breeding techniques. The collection concludes by discussing developments in understanding and managing pests and diseases. Achieving sustainable cultivation of tomatoes will be a standard reference for horticultural scientists in universities, government and other research centres and companies involved in tomato cultivation.

‘Fascinating...I’ll never look at a rose in quite the same way again.’ Adrian Tinniswood The rose is bursting with meaning. Over the centuries it has come to represent love and sensuality, deceit, death and the mystical unknown. Today the rose enjoys unrivalled popularity across the globe, ever present at life’s seminal moments. Grown in the Middle East two thousand years ago for its pleasing scent and medicinal properties, it has become one of the most adored flowers across cultures, no longer selected by nature, but by us. The rose is well-versed at enchanting human hearts. From Shakespeare’s sonnets to Bulgaria’s Rose Valley to the thriving rose trade in Africa and the Far East, via museums, high fashion, Victorian England and Belle Epoque France, we meet an astonishing array of species and hybrids of remarkably different provenance. This is the story of a hardy, thorny flower and how, by beauty and charm, it came to seduce the world.

Practical Drainage is easy to read and presented in a non-technical style generously supported with helpful illustrations. There are three key messages in this book: water moves sideways only slowly through soil--leading to a detailed description of how drains work; the how-and-why of perched water table methods of construction; and sands are different from one another--they must be tested before use in turf root zones. These key messages are preceded by detailed descriptions of how water moves into soils and the effects of compaction on that movement. The final chapters give step-by-step guidelines for calculating drain spacings and depths, based on measurements of the hydraulic conductivity of the soil and its various layers. There are also chapters about how to measure hydraulic conductivity and how to design and install sub-soil drainage systems.

Anyone who observes fruit trees may wonder how or why they behave in specific ways. Some trees grow upright while others have a spreading habit. Some produce many flowers and small immature fruit only to drop most of the fruit later on; others grow more strongly on their sunny side than their shady side. It is common to ascribe such behavior to the tree as a whole and state that trees preferentially "allocate" resources to specific organs. However, this is the wrong approach to understanding tree functioning and behavior. Trees are not in control of what they do. What trees do and how they function is shaped by the individual organs that make up the tree, not by the tree as a whole. The genetic code only indirectly determines the habit, structure and behavior of a tree by defining the behavioral and functional limits of the component organs, tissues and cells. Unlike animals that have a mechanism for collective control of the whole organism - a central nervous system - trees (and plants in general) are more appropriately considered as collections of semi-autonomous organs. These organs are dependent on one another for resources, such as water, energy and nutrients, but control their own destiny. This book presents a clear set of integrative concepts for understanding the overall physiology and growth of temperate deciduous fruit trees. The emphasis is on overarching principles rather than detailed descriptions of tree physiology or differences among the numerous species of fruit trees. Although the focus is on deciduous fruit trees, many aspects apply to evergreen fruit trees and trees that grow naturally in unmanaged situations. Highly relevant for students and researchers in pomology, horticulture and plant sciences, the book is also suitable for practitioners, extension staff, and novice fruit tree growers.

Climate change and increased climate variability in terms of rising temperatures, shifting rainfall patterns, and increasing extreme weather events, such as severe drought and devastating floods, pose a threat to the production of agricultural and horticultural crops a threat this is expected to worsen.

Climate change is already affecting and is likely to increase invasive species, pests, and disease vectors, all adversely affecting agri-horticultural crop productivity. Advances in agricultural knowledge, science, and technology will be required to develop improved crop traits, such as temperature, drought, pest, and salt tolerance. This two-volume set gives readers an understanding of the issues and makes suggestions for ways to mitigate adverse climate change effects on crops.

The focus of Volume 1: The Principles and Applications in Horticultural Science is to identify impacts and suggest appropriate and effective adaptation and mitigation strategies. Volume 2: Impact, Adaptation, and Mitigation focuses on the impact of climate change on horticultural crops and offers ways to adapt practices to mitigate adverse effects. Together, the two volumes offer a diverse selection of chapters that address issues of importance to those in the horticulture industry, researchers, faculty, and others.

Sustainable Horticulture, Volume 2: Food, Health, and Nutrition addresses some of the most important topics facing horticulture around the world today. This volume, part of the two-volume compendium, focuses on research trends in sustainable horticulture that include postharvest management and processed food production from horticulture crops, crop protection and plant health management, and horticulture for human health and nutrition. Global food demand is expected to be double by 2050, while at the same time the production environment and natural resources are continually shrinking and deteriorating due to many complex factors. Horticulture, a major sector of agriculture, is vital to enhancing crop production and productivity in parity with agricultural crops to meet the emerging food demand. Implementing sustainable models of crop production is really an enormous endeavor. Promising technologies and management options are needed to increase productivity to meet the growing food demand despite deteriorating production environments.

Plant breeding practices have improved the livelihoods of millions. Current breeding practices have allowed farmers to produce enough crops to feed growing populations, added significant profits in the grain trade, and minimized the amount of land needed for agricultural production by permitting more intensive use of existing crop lands. This volume reviews the status of the major challenges, approaches, and accomplishments of plant breeding programs from around the world.

This volumeoriginated from the Arnel R. Hallauer International Symposium held in Mexico City in 2003, and represents contributions from an international field of leading plant breeding researchers. The coverage is broad and comprehensive and provides the latest developments affecting grains, trees, fruits, nuts, and forage crops.

"Plant Breeding: The Arnel R. Hallauer International Symposium" is an essential resource for agronomists, horticulturists, and plant biologists.

Thirty years ago, in vitro propagation was a new technique for producing plants, and Lydiane Kyte s Plants from Test Tubes became the standard work on the topic.The new fourth edition has been thoroughly revised and updated to reflect the many advances in science and technology, including the five accepted sequential stages of micropropagation. Ten new plants have been added. This in turn has greatly expanded the already extensive bibliography. Among the new topics that have been introduced or expanded on are embryo culture for breeding, somaclonal variation, anther culture, somatic embryogenesis, cryopreservation, and genetic engineering. More ornamental plant examples are given and many new illustrations provided, including a chronology of discoveries in micropropagation."

Ornamental plants are plants grown for decorative purposes. They include cut flowers, bulbs, potted plants, shrubs and trees for gardening and landscape design. Like other crops, ornamentals face challenges such as biotic and abiotic stresses as well as the need to develop more sustainable, 'climate-smart' methods of cultivation. This collection reviews the rich range of research addressing these challenges. Part 1 discusses advances in understanding plant physiology, genetic diversity and breeding techniques. Chapters cover recent research on how plants respond to abiotic stress, ways of exploiting genetic diversity to improve target traits, advances in both conventional and marker-assisted breeding techniques, as well as their use to produce abiotic stress-resistant varieties. Part 2 surveys advances in cultivation techniques in such areas as nutrition, irrigation, protected cultivation and integrated disease management.
