Efecto de extractos acuosos de dos meliaceas sobre Meloidogyne incognita (Nematoda, meloidogynidae)

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.
