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.
