In greenhouse experiments, Pratvlenchus brachyurus (Godfrey 1929) Filipjev and Stekhoven 1941 and Helicotylenchus pseudorobustus (Steiner 1945) Golden 1956 as individual pathogens did not suppress the top growth and root weight of sugarcane. Histological studies of the roots showed damage to cortical and stelar tissues by P. brachyurus and eggs were laid in the metaxylem, while activities of H. pseudorobustus was limited to the cortical tissue. Although, both species are parasitic to sugarcane, only P brachyurus showed pathogenic potential.
