The effects of the aqueous extracts of Euphorbia myrsinites (Euphorbiaceae) and Urginea maritima (Liliaceae) on the damage of Meloidogyne inccgnita (Nematoda: Heteroderidae) to tomato plants was evaluated. The trials were conducted in two series in climatized rooms and in greenhouse conditions. The results of both the climatized rooms and greenhouse trials are parallel each other. All dilutions (1:100, 2:100 and 4:100 v v(-1)) of the extracts applied to the soil reduced the root galling caused by M. incognita and enhanced tomato yield compared to an untreated control. Efficacy of the highest concentration (4:100 v v(-1)) of both extracts on the control of M. incognita was similar to the positive chemical control (Oxamyl). The highest concentration of U. maritima was superior to the extracts of E. myrsinites. Aqueous extracts from these two plants reduced the damage of root-knot nematodes.
