Effect of plant essential oils on the mortality of Ditylenchus dipsaci (Kühn, 1857) nematode under in vitro conditions

With the need to obtain new methods protect seed material from Ditylenchus dipsaci (KĂźhn, 1857) nematodes, a study was conducted evaluate nematicidal effects of several plants' essential oils on mortality D. dipsaci. Tests were performed under in vitro conditions; concentration 2 000 ppm tested, nematodes added into diluted oils, and numbers living/dead scored after 4 24 h. The results show significant effect plant mortality, with highest efficacy found for oil Cinnamomum cassia ((L.) J. Presl), 100% observed even
