Abstract

Six endophytic fungal isolates (Fusarium spp.) were chosen from our collection and investigated for their ability to enhance of tomato toward activity of root-knot nematode Meloidogyne incognita in greenhouse experiments in Vietnam. When the root system of tomatoes were pre-inoculated with the four endophytes, the Meloidogyne incognita was reduced significantly 29-56% the number of root galls and 34-56% the number of egg masses six weeks after nematode inoculation, respectively. Induction of induced systemic resistance of M. incognita in tomato roots by the same endophytic fungi was tested. Depending on the isolate, the number of galls decreased between 29-44% and the number of egg masses reduced 37-42% in treated tomatoes with endophytic isolates when compared to those un-treated without fungi. This is the first time that systemic resistance induced by a fungal endophyte has been investigated in tomato in Vietnam.
