Preliminary report of plant parasitic nematodes associated with important crops in Trinidad.

A survey was undertaken to investigate the plant parasitic nematodes associated with important crops in Trinidad. A total of 214 soil and root samples from 29 plant species contained mixed populations of 23 plant nematode genera. The average number of nematodes per 200 ml soil plus 10 gm root sample ranged from 336 to 15,580 with an overall average of 3,060. The most common plant nematode genera were Aphelenchus, Pratylenchus, Helicotylenchus, Meloidogyne, Rotylenchulus, Tylenchus and Tylenchorhynchus. The plant nematode species identified were also listed.
