Histopathological studies revealed that Meloidogyne javanica larvae entered roots by puncturing action of the stylet. The cells adjacent to nematode were severely damaged causing cell congestion. A number of cells had egg masses and sections of larvae. The medullary cells were unequal in size. Giant cells were present with broken cell walls. The pathological symptoms observed in the present findings, especially disruption of cortical tissue ultimately affected plant growth by reducing absorption of water and nutrients.
