Some plant extracts that have toxic effects to nematodes might be used as an alternative control method of plant parasitic nematodes.For this purpose; two different preparation types (cold and hot) of extracts of Viscum album, Rosmarinus officinalis, Circium arvense, Myrtus communis, Ocimum basilicum, Capsella bursa-pastoris, Melisa officinalis, Taraxacum officinale, Matricaria chamomilla, Chelidonium majus, Humulus lupulus, Mentha pulegium were searched the effects on Meloidogyne arenaria Neal, 1889 (Tylenchida: Meloidogynidae) in petri and pot experiments.Cold extracts were exhibited lower egg hatching and higher juvenile mortality than hot extracts except R. officinalis.Cold extract of C. arvense was completely inhibited egg hatching.The pot experiment conducted in a completely randomized block design with four replications on greenhouse condition at 27 ±2°C.Cold extract of V. album had the lowest root galling on tomato by followed hot extract of M. communis and C. bursa-pastoris.The most effective cold extract was M. pulegium and hot extract was H. lupulus on nematode reproduction.The highest stem length, root weight, fresh and dry stem weight were recorded by the treatment with cold extracts of T. officinale and R. officinalis, hot extracts of O. basilicum and V. album, respectively.
