T. annulatus was pathogenic to potted sugarcane var. Phil. 56226. Height of sugarcane at 400, 600 and 1000 inoculum level/pot, was significantly lower than the control, by 10.44%, 11.41% and 11.79%, respectively, 20 weeks after inoculation. Top weight reduction at 400, 600 and 1000 inoculum level/pot were 29.99%, 33.48% and 39.29%, respectively, as compared with the control. With 400, 600 and 1000 inoculum levels/pot, fresh root weights were reduced by 46.55%, 47.14% and 48.90%, respectively, as compared with the control. The average nematode population at 50, 100, 200, 400, 600 and 1000 inoculum level/pot increased by 493, 2248, 2616, 5828, 6039 and 7184 or 9.86, 22.48, 13.08, 14.57, 10.06 and 7.18 folds, respectively. The life cycle of T. annulatus on rice seedling in 1% plated sterile water agar was completed in 20-22 days
