This book provides the most comprehensive and up-to-date review of research on vegetable plants associated with root-galls disease caused by root-knot nematodes (RKNs), Meloidogyne spp. Vegetables retain a key position in cultural cuisines and their consumption worldwide due to rich sources of micronutrients, including vitamins, minerals and antioxidants, but root galls disease of these crops caused by RKNs steals both quantity and quality from production. The field of plant nematology has experienced exponential growth over the past decade, and these RKNs are now known as widely damaging obligate plant parasites of vegetable plants. Advances are being made in understanding their biology, parasitism in the root system, giant cell development, root gall formation, chemical signalling, root-knot disease complexes, and management systems. This compilation provides an invaluable resource for studying root-galls disease of vegetable plants to those readers associated with plant nematology, plant pathology, plant protection, and agricultural science, including researchers, teachers, advanced undergraduates and graduate students, and even agricultural extension agents and farmers.
