Satureja montana and Ruta graveolens essential oils were added to plant/nematode co-cultures.
Essential oils nematotoxicity and phytotoxicity was assessed at 0.5 μl/ml culture medium.
Pinus pinaster shoots and P. pinaster with Bursaphelenchus xylophilus co-cultures were the test systems.
S. montana essential oil showed phytotoxicity, inducing in vitro shoot chlorosis and drooping.
R. graveolens essential oil induced no detectable morphological changes.
