Coker 298, a flue-cured tobacco cultivar resistant to Fusarium wilt and susceptible to Meloidogyne incognita, was grown in a split-root system and inoculated with both Fusarium and root-knot nematodes in various combinations to examine the influence of the nematode on wilt resistance. Only plants inoculated with both pathogens on the same half-root system developed severe wilt symptoms. Thus, M. incognita did not induce a systemic alteration of Coker 298 Fusarium wilt resistance.
