The effect of Radopholus similis, Pratylenchus araucensis, Meloidogyne spp., and their interaction was evaluated in seedlings of Musa AAB ‘Dominico Hartón’. The study was conducted in a nursery in Palestina, Caldas department, Colombia. Forty-day-old plantain seedlings were infected separately with 750, 1,500, 2,250 and 3,000 of each species of nematodes/plant. Two experiments were conducted to evaluate the damage of R. similis, P. araucensis, Meloidogyne spp. and the mixture of 750 R. similis + 750 P. araucensis + 750 Meloidogyne spp. compared with the mixture of different proportions (1,500, 2,250 and 3,000 of each species of nematodes). Noninfected plants were included as a control treatment, for a total of 17 treatments in a randomized complete block design with ten replications. Twelve weeks after inoculation, all nematodes, both alone and in combination, reduced (p < 0.05) plantain dry root and shoot weight. In two experiments, R. similis, P. araucensis, and Meloidogyne spp. alone, each with a population density of 3,000, reduced (p < 0.05) root dry weight by 32.5%, 9.5% and 49%, respectively, and decreased (p < 0.05) shoot dry weight by 21.5%, 23%, and 31.5%, respectively, compared to the control. The interaction of nematodes with the lowest population decreased root (33%) and shoot (21%) weight. We conclude that the growth of ‘Dominico Hartón’ seedlings was affected by plant-parasitic nematodes, but the greatest damage occurred with concomitant nematode infection.
