Two phenylpropanoid and one alkaloid secondary metabolites were isolated identified from culture filtrates of Photorhabdus l. sonorensis strain Caborca. The three showed selective nematicidal and/or nematistatic activities against two important plant parasitic nematodes, the root-knot nematode ( Meloidogyne incognita ) citrus Tylenchulus semipenetrans ).
