In a glasshouse pot experiment on the pathogenicity and interactions of Meloidogyne incognita, M. hapla and Pratylenchus brachyurus on 4 cultivars of tobacco, the cultivars 'Hicks' and 'NC 2326' were susceptible to each nematode and 'NC 95' and 'NC 2512' resistant only to M. incognita. Mean heights of susceptible plants were depressed but fresh weight of tops did not differ significantly. Meloidogyne spp. increased fresh weight of susceptible (but not the resistant) roots.
