Although there are reports in the literature of root-knot nematodes (Meloidogyne spp.) occurring in association with noni (Morinda citrifolia L.), a plant that helps in the prevention and cure of some human diseases, there are no reports of a nematological survey in the crop in Brazil in commercial areas. The aim of this work was to carry out a survey of phytonematodes associated with noni in commercial plantations in Espírito Santo state, Brazil. The soil and root samples were collected on properties in the counties of Colatina and São Roque do Canaã, the main producers in the upland region of Espírito Santo. The presence of M. javanica was identified in all samples using the technique of esterase isoenzyme electrophoresis. This is the first report of this pathosystem in Espírito Santo State.
