Abstract
In an extensive survey conducted in Kerala and Karnataka States plant parasitic nematodes belonging to 22 genera have been isolated and identified from the root zone of arecanut. R. similis on inoculation produced lesions, rotting and black tip of roots. Possibility of R. similis as an aggravator in the disease complex is brought out. Recorded wide spread occurrence of R. similis in all soil types in Kerala and Karnataka States. Intercultivation of banana in arecanut gardens favours the multiplication of R. similis. Chances for recovery of R. similis from soil samples around roots harbouring them have been, found to be less than 50 per cent.
