ABSTRACT
During the last few
decades, researchers have been in the search for environmental friendly ways to
cope with agricultural pests, instead of using chemical pesticides. The use of
essential oils has a high potential to become an alternative control strategy
against plant parasitic nematodes. This study was conducted to determine the
toxicity of 10 essential oils (Artemisia
absinthium, Citrus bergamia, Eucalyptus citriodora, Hypericum perforatum, Lavandula
officinalis, Mentha arvensis, Ocimum basilicum, Piper
nigrum, Thymus serpyllum and Zingiber officinale)
against the second stage juveniles of the root-knot nematode Meloidogyne
incognita. The aqueous solutions of these essential oils have been applied
to the second stage juveniles in three different concentrations (1%, 3% and 5%) at four
different application time
intervals (12, 24, 48 and 72 h).
The interactions between the variables have been examined with repeated measure
analysis of variance (ANOVA). This showed that the interactions of essential
oil-time and essential oil-concentration were statistically significant, and it
is concluded that L. officinalis, A. absinthium, P. nigrum, C. bergamia and M. arvensis have the most toxic effect in all concentrations and
times, respectively.
