200 g of soil, collected from each of two contiguous horizons (0-10 and 11-20 cm) sampled in areas with relatively poorly growing sugarcane crop in eight plots totalling over 810 ha, were washed, and the number and genera of phytophagous nematodes present were recorded. Roots of sugarcane and of weeds on the plots were also examined after washing with water and then staining in acid fuchsin lactophenol (0'1 %). The 15 genera of nematodes identified included three potential virus transmitters and two endoparasites-Meloidogyne and Pratylenchus spp. Seven species of dicotyledonous weeds were hosts of Meloidogyne spp. and had stubby root end-growths similar to those found on the sugarcane roots, the cause of which is unknown.
