MAREGGIANI, Graciela; ZAMUNER, Norma  e  ANGAROLA, Gisella. Efecto de extractos acuosos de dos meliaceas sobre Meloidogyne incognita (Nematoda, meloidogynidae). Rev. latinoam. quím [online]. 2010, vol.38, n.1, pp. 68-73. ISSN 0370-5943.

The bioactivity of six aqueous extracts 10% and 30% (P/V), containing terpenoids from Melia azedarachand Trichilia glauca (Meliaceae) in their chemical constitution, was evaluated against the pest Meloidogyne incognita (Nematoda, Meloidogynidae). Results show that the natural products assayed had a good nematicidal activity, because they had moderate lethal effects (mortality: 23-46.2%, depending upon treatment). These data show that the interesting properties of both Meliaceae could be used in orchard nematode management, in replacement of synthetic nematicides.
