Sixteen species of plant-parasitic nematodes in 11 genera were recovered from 54 samples collected from the rhizosphere of maize in the departments of Cauca and Valle del Cauca, Colombia. Pratylenchus spp. were recovered most frequently from roots and second most frequently, after Helicotylenchus spp., from soil. P. zeae was by far the most common species of the genus recovered; the highest numbers were more than 91,000/g of dry root. H. borinquensis and Paratrichodorus minor were most prominent in the mountainous areas of Cauca but were found infrequently in Cauca del Valle.
