Mycotoxins continue to be a very serious threat to human health and a major concern for those entrusted with regulatingthesafetyoffoodandfoodproducts.Infectionofcerealsandothercrops, notablegrapevine, byFusarium, Aspergillus andPenicillium are a world-wide problem and recent epidemics in Europe, the USA and Canada have focused attention on this problem. A previous Special Issue of the European Journal of Plant Pathology (108 (7) 2003) was concerned with the nature of these toxins and the fungi that can produce them. The aim of this publication is to review the environmental factors that in?uence the success of these fungi as pathogens and as organisms affecting stored products, and to discuss how these factors can also in?uence the amounts of toxin that accumulate. These reviews were originally presented at a Workshop of the EU COST Action 835 entitled 'Agriculturally Important Toxigenic Fungi' (Chairperson Antonio Logrieco, Bari, Italy), held in East Malling, UK at the Horticultural Research International in September 2002. We hope the information provided will stimulate scientists world-wide to assess the risk of toxins accumulating in plants under a range of environmental conditions and that this will provide an insight into how the accumulation of these toxins can be kept to a minimum.

This collection features four peer-reviewed literature reviews discussing fungal diseases of apples. The first chapter discusses the main pre- and postharvest pathogens affecting apple production. The chapter also reviews recent advances in biological, chemical and cultural forms of disease management to optimise production, maintain fruit quality and enhance sustainability. The second chapter reviews the epidemiology of apple scab. The chapter explores the role of host resistance, as well as techniques to manage apple scab and minimise crop losses, including fungicide application and the use of biocontrol agents. The third chapter reviews preharvest fungal and bacterial diseases as well as viruses of tree fruit. It looks at advances in technology for pathogen detection as well as methods of integrated disease management, including biological and cultural control. The final chapter reviews the development of apple varieties that are resistant to a number of important diseases, including apple scab, powdery mildew, fire blight, nectria canker and Marssonina apple blotch. The chapter also considers the use of DNA-based selection techniques for developing resistance and the mechanisms on which resistance depends.

"In conclusion, this extremely comprehensive, accurate and useful volume of reviews in the Burleigh Dodds series is recommended as an important reference for professionals and students alike." ISHS - Chronica Horticulturae This collection reviews advances in understanding and managing key diseases and insect pests of tree fruit. Part 1 summarises current research on what causes key fungal diseases (apple scab, powdery mildew, apple canker and brown rot) as well as viral diseases (apple mosaic virus and plum pox). Building on this foundation, Part 2 discusses integrated fruit disease management techniques such as improved surveillance, breeding disease-resistant varieties, improved fungicide application as well as the use of biocontrol agents. The second half of the book focuses on the ecology of major insect pests (aphids, tortricid moths, mites and spotted wing drosophila). The final part of the book reviews ways of improving integrated pest management (IPM) techniques for tree fruit, from monitoring and forecasting to agronomic practices to methods of biological control and optimisation of insecticide use. With its distinguished editors and expert team of chapter authors, this will be a standard reference on understanding and managing key diseases and insect pests of tree fruit.
