Effect of some plant extracts on Meloidogyne arenaria Neal, 1889 (Tylenchida: Meloidogynidae) and tomato

Abstract

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.

Nematicidal activity of various aqueous extracts against root-knot nematodes (Meloidogyne chitwoodi)

“…The plant roots were evaluated according to the 0-5 gall index (Hartman & Sasser 1985). Additionally, the fresh and dry weights of roots and plant height were measured according to Aydınlı & Mennan (2014).…”

“…In order to overcome these problems, it is crucial to adopt effective and environmentally friendly methods to control nematodes (Nolling & Becker 1994). One such practice would be the use of plant extracts that have nematicidal properties (Aydınlı & Mennan 2014). The flowers, shoots, and leaves of Nerium oleander L. have been shown to have nematicidal effects on Meloidogyne javanica (Treub 1885;Chitwood 1949;Moosavi 2012).…”

Efficacy of hazelnut (Corylus avellana L.) dried husk extract and dried husk compost against root-knot nematodes (Meloidogyne spp.) on tomato

“…(2007) pointed out that aqueous extracts of neem cake (5% dose) and neem leave (1.5%) decreased the female invasion in the roots at approximately 30 % lower and the gall index to 12 fold lower on tomato agains M. javanica, respectively. Aydınlı and Mennan (2014) used the aqueous extracts diffrent plants against M. arenaria and observed the lowest gall index (5.0) on the roots of tomato exposured by Viscum album cold extract.…”

Bazı baharat ekstraktlarının Meloidogyne arenaria (Neal, 1889) Chitwood, 1949 (Tylenchida: Meloidogynidae)’ya karşı nematisidal potansiyellerinin araştırılması

“…Spices obtained by drying various plant parts such as roots, leaves and seeds, may be toxic to nematodes. Many studies show that extracts and oils derived from spice plants have negative effects on nematodes by inhibiting egg hatching, causing second-stage juvenile (J2) immobility, or being lethal (Oka et al, 2000;Ibrahim et al, 2006;Abbas et al, 2009;Aydınlı & Mennan, 2014;Youssef et al, 2015;El-Nagdi Wafaa et al, 2017). Therefore, in this study, the nematicidal potential of aqueous extracts from 13 spices plants for management of the root-knot nematode Meloidogyne arenaria (Neal, 1889) Chitwood, 1949 was investigated in the laboratory and in pot experiments.…”
