Development of Meloidogyne incognita Inhibited by Digtaria decumbens cv. Pangola

Population densities of the root-knot nematode, Meloidogyne incognita, were lower after 90 days in soil planted to digitgrass (Digitaria decumbens cv. Pangola) than in soil left fallow or planted to tomato. Roots of tomato seedlings interplanted with Pangola digitgrass were less galled than were roots of tomato seedlings planted alone. Fewer second stage larvae invaded roots of Pangola digitgrass than tomato and those that entered the grass roots failed to develop beyond the late second stage.
