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While it is acknowledged that the science of ecology should be the basis of agroecological planning, many analysts have out-of-date ideas about contemporary ecology.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

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.

"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.

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.

Soilborne microbial plant pathogens including oomycetes, fungi, bacteria and viruses cause several economically important destructive diseases and the symptoms of infection can be recognized only after the pathogen has invaded many tissues primarily vascular tissues of susceptible plants. This condition places formidable challenges in investigating different aspects of host-microbial pathogen interactions. Early detection of infection and precise identification, differentiation, and quantification of the microbial plant pathogens in plants, soil and water sources are essential requirements for development of effective tactics to reduce the incidence and spread of the diseases caused by them. As the microbial plant pathogens differ in their virulence and sensitivity to the environment and chemicals applied, it is imperative to assess the extent of variability in the concerned pathogens. This first volume of a two-volume set introduces disease-causing microorganisms including oomycetes, fungi, bacteria, and viruses found in soils. It focuses on the biology, detection, and identification of soilborne bacterial, fungal, and viral plant pathogens. This volume discusses various techniques based on biological, immunological and genetic properties of the pathogens indicating their advantages and limitations for selecting the appropriate technique to fulfill the requirements. Features: Presents techniques useful for detection, identification, quantification of microbial plant pathogens in plants, soil, and irrigation water from waterbodies. Highlights subversive activities of viruses, resulting in the breakdown of host defense systems. Discusses RNA silencing in infected plants by viruses and posttranscriptional gene silencing (PTGS) functioning as an endogenous mechanism in plants against virus infection. Presents information on methods of assessment of genetic variability and sensitivity of microbial plant pathogens to chemicals and adverse environmental conditions.

Crop disease management strategies revolve around the principles of exclusion, eradication and immunization. Cultural practices are aimed at preventing or reducing the accumulation of pathogen population (inoculum). Development of cultivars with genetic resistance by transgressing resistance gene(s) through traditional breeding procedures or biotechnological techniques is the most effective and acceptable strategy, as it is environment-friendly and does not need any additional cost to the grower. Assessment of different grades of resistance of cultivars or genotypes to soilborne microbial pathogens has been possible by quantifying pathogen populations or their DNA contents in the test plants by applying biological and molecular methods. This second volume of a two-volume set focuses on the soilborne microbial plant pathogens and the diseases caused by them. The book provides information on ecology and epidemiology of soilborne microbial plant pathogens and various strategies applicable for effective management of diseases. Chapters cover exclusion and prevention strategies; improvement of host plant resistance; biological management; application of chemicals; and integration of these disease management strategies. Features Discusses various aspects of soilborne microbial plant pathogens to develop effective methods of managing diseases. Presents information on epidemiology and ecology of soilborne microbial plant pathogens. Facilitates the application of management strategies alone or in combination with others for effective suppression of disease development. Features information on application of biotic and abiotic biological control agents (BCAs) to suppress pathogen development either by directly acting on the pathogen(s) or indirectly by enhancing host resistance to the pathogens. Employs biotic and abiotic biocontrol agents either to replace or reduce the use of chemicals is an achievable approach for managing the soilborne microbial pathogens.

Soil has a versatile role in supporting the development of a wide range of organisms, including plants and microorganisms. Soilborne pathogens and root diseases are the primary limiting factor in many crops and tend to be very difficult to control. This first volume of a two-volume set introduces disease-causing microorganisms including oomycetes, fungi, bacteria, and viruses found in soils.
