Now established worldwide as the standard guide to the recognition and understanding of the causes of deterioration in temperate and tropical fruits and vegetables, these two superbly illustrated full-colour volumes deal clearly, concisely and systematically with each of the main diseases and disorders, emphasising those of importance to international trade. Dr Snowdon has designed each volume to be used in two different ways: 1. Full colour photographs and practical text provide the basis for preliminary identification by the owner or surveyor. 2. Using the microscope drawings and references, diagnosis can then be confirmed or modified by a specialist.
