Interaction between the endomycorrhizal fungus Glomus fasciculatum and the root-knot nematode, meloidogyne incognita on tomato

The interaction between Glomus fasciculatum and Meloidogyne incognita in tomato was studied in two phases under greenhouse conditions. In the first phase, two locally adopted tomato varieties Pusa Ruby and Pusa Early Dwarf were evaluated for VAM susceptibility. Pusa Ruby variety was found to be more susceptible to G. fasciculatum. VAM colonisation was found to reducethe root-knot infestation. Application of VA-mycorrhiza first followed by nematodes resulted ingreater reductionin nematode infestation than the simultaneous inoculation or nematode first followed by mycorrhiza.
