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