Nematodes are major pests of a number of temperate crops and can cause significant economic losses to farmers. This book provides a comprehensive account of such parasites, with chapters focusing on nematode pests of the main crops of importance in agriculture, horticulture and forestry. Eleven chapters thus consider: potatoes, sugar beet, vegetable crops, oilseeds and grain legumes, cereals, grassland and forage crops, forest trees, deciduous fruit and nut trees, soft fruits and grapevines, ornamental and bulb crops, and mushrooms and greenhouse crops. There are also six further chapters on more general issues such as extraction and identification of nematodes, modelling population dynamics and yield losses, molecular aids to diagnosis, use of nematodes in biological control of insects, quarantine, and cellular and molecular approaches to control. Written by leading authorities from the USA, UK, Canada, France, Netherlands, Bolivia, Australia and New Zealand the book overall is a definitive reference work for plant pathologists in general, and nematologists in particular.
