The effect of grasses on the reaction of Desmodium ovalifolium (accession CIAT 350) to Meloidogyne javanica was measured. The nematode was less pathogenic to the legume in association with 22 of 49 grasses, including accessions of the promising pasture grasses Andropogon gayanus, Brachiaria humidicola, B. mutica, B. ruziziensis, Panicum maximum, and Hemarthria altissima. Roots of these grasses may produce substances that are toxic to M. javanica.
