Abstract
Root-knot nematodes (Meloidogyne incognita) often occur together with the wilt fungus (Fusarium oxysporum f. lycopersici) on tomato in a plant disease complex. An interaction between the plant and the nematode may transform a genetically resistant host plant into one that is susceptible to the wilt-fungus and which subsequently develops wilt symptoms. Bridging and grafting experiments indicate that a factor emanating from this nematode-plant interaction is translocated considerable distances to the upper foliage across a resistant scion. Disease indices based on chlorosis of the foliage and on propagule counts from stem exudates showed primarily distal rather than proximal translocation of the factor.
