Effect of some aromatic leaf extracts on egg hatching of root-knot nematode, Meloidogyne javanica (Treub, 1885) Chitwood, 1949 (Nematoda: Meloidogynidae)
Root-knot nematodes are one of the most important limiting factors affecting plant growth and productivity. Currently, synthetic pesticides are the main chemicals used to control nematodes, but natural products can provide a safer alternative. Nematicidal compounds have been identified in a wide variety of plant species. A research was conducted to evaluate potential of aromatic leaf extracts from Tagetes patula, Eucalyptus globulus, Rosmarinus officinalis, Thymus vulgaris, Mentha piperita and Laurus nobilis, in controlling the hatch of eggs of the root-knot nematode, Meloidogyne javanica. Five concentrations of water soluble leaf extracts from the six plant species were filtered, added to petri dishes and infested with eggs of M. javanica. The best results for all concentration values were obtained with T. patula and E. globulus with no hatching within 48 h. At the end of this period, the control trial value was found to be 44.04 %.
