NEMATICIDAL ACTIVITY OF EUDISTOMA VIRIDE TOKIOKA, 1955 Authors: C. Pratheepa And M. Paripooranaselvi*
ABSTRACT
Nematicidal activity refers to the lethal action of a nematicide on specific and vital life
processes within tissues of the nematode. Now-a-days there is great urgency for discovering
new ecofriendly tools for concerning about soil degradation and toxicity of agricultural
chemicals to non-target organisms. The aim of study work was to investigate the nematicidal
activity of the ethanolic extract of Eudistoma viride against root-knot nematode Meloidogyne
incognita. Samples of Eudistoma viride Tokioka, 1955 were collected during the low tide from
the intertidal rocky area of Hare Island. Egg masses of Meloidogyne incognita was isolated
from the root of the Banana tree. The death rate of nematodes was noted on 2 days interval
during the experimental study. Result indicated that the highest concentration of ethanolic
extract of Eudistoma viride treated group has a maximum juvenile mortality (70%) and also
showed nematicidal activity in a dose dependent manner. It was concluded that the ethanolic
extract of Eudistoma viride can be utilized for biocontrol of root knot nematode and this method
of management is cheap, eco-friendly and free from any hazards.
