Pathogenicity of Radopholus similis studied on sugarcane var. Co-449 revealed that the damage was maximum at the highest initial inoculum level of 10,000 nematodes per plant and the reduction was highly significant with respect io cane weight (16.07%), leaf weight (54.98%), root weight (65.13%) and root volume (80.02%). A minimum of 100 nematodes/plant in 12,000 cm3 soil was found to be the damage threshold level of R. similis on sugarcane. Reduction in the mass of feeder roots was the most significant effect on the plant.
