Nematicidal Activity of Essential Oils from Apiaceae Family Plants of Turkey Against Root Lesion Nematodes

In our study, the nematicidal activity of 12 essential oils from Apiaceae family plants of Turkey against Pratylenchus penetrans, P. thornei and P. neglectus root lesion nematodes were investigated. The study was conducted in vitro conditions and concentration of 1000 ppm of each essential oil was used. The nematicidal effect was found to depending on root lesion nematode species and high nematicidal effect were found P. neglectus species; Coriondrum sativum L., P. thornei species; Ferulago cassia Boiss and P. penetrans Foeniculum vulgare Miller and Anethum graveolens L. Mortality rates depending on essential oil applications varied between 24.3-64.7% in P. neglectus species, 23.7-66.7% in P. penetrans and 33.7-85.0% in P. thornei. In this study, the nematicidal activity were found high that essential oil active ingredients of plants containing linalool, phallendrene and 2,3,6 trimethylbenzaldehyde components while the plants containing anethole and carvone components were medium nematicidal activity and containing caratol and curzerene components showed low. It has been understood that the nematicidal activity of Apiaceae family species against Pratylenchus species are high but variable, therefore, more definite results can be achieved by testing the effectiveness of highly active essential oils using different doses in field conditions.
