In case of multi-pathogenic infection on host plant inter-pathogenic competition for food and survival are very much expected. In order to study the effect of early establishment of either of the two test pathogen i.e root knot nematode Meloidogyne incognita (Kofoid and White) Chitwood and root rot fungus Fusarium solani (Mart.)Sacc. on plant growth characters, nematode multiplication and root rotting, chilli seedlings (variety “Japani longi”) were inoculated with these pathogens individually and in their various combinations of simultaneous, pre and post inoculations. Simultaneous (Mi+Fs) and sequential inoculation of M. incognita 15 days prior to F. solani showed synergistic interaction and caused greater reduction in plant growth parameters as compare to damage caused by either of the pathogen alone. However multiplication of nematode and number of galls/root system were reduced significantly as compared to individual inoculations .Intensity of root rot was increased in presence of M. incognita as compared to when F. solani was inoculated alone.
