In this research, control of tomato root- knot nematode (Meloidogyne incognita) was conducted using tea dust residues at different rates. First, the species and race of nematode were identified by employing diagnostic keys. Then, with 5 replications in complete randomized design. Tea dust residues were used at 9 treatments (0, 5, 10, 15, 20, 25, 30, 35 and 40 g/kg of soil). Statistical analysis on mean treatments rates showed that treatment with 25 g/kg soil economically was effective in growth rates and reduction in gall index.
