Plant-parasitic nematodes are recognized as one of the greatest threats to crops throughout the world. Nematodes alone or in combination with other soil microorganisms have been found to attack almost every part of the plant including roots, stems, leaves, fruits and seeds. Although worldwide recognition of nematodes as important casual agents of plant diseases did not occur until the middle of this century, nematodes were studied more than 100 years earlier.
