Host-Parasite Relationship of Tobacco and Root-knot Nematode, Meloidogyne javanica (Treub) Chitwood, Influenced by Tobacco Mosaic Virus Infection

Studies on the influence of TMV in tobocco having M. javanica infection revealed that TMV influences the host-parasite relationship of M. javanica. The virus-nematode infection complex had marked effect on the host. Higher nematode population was observed in roots and soils of TMV infected tobacco plants. The maximum synergistic interaction between TMV and M. javanica to the tabacco plants occured when both pathogens infect the host simultaneously.
