Abstract
Extensive surveys of arecanut growing areas of Kerala, Karnataka and Tamil Nadu were conducted during 1976 to 1980. A total of 822 each of soil and root samples were collected from healthy and Yellow Leaf Disease affected arecanut gardens. Twenty eight genera of plant parasitic nematodes were isolated from the root zone of arecanut. The burrowing nematode, Radopholus similis was obtained from maximum number of root samples. Rotylenchulus reniformis, Helicotylenchus dihystera, Hemicriconemoides mangiferae, Caloosia longicaudata and Hoplolaimus seinhorsti were the most widely distributed ectoparasitic forms in the soil samples of arecanut growing areas in South India.
