In vitro study on the nematicidal effect of different plant extracts on Pratylenchus penetrans and Meloidogyne chitwoodi

Abstract

The purpose of this in vitro study was to evaluate the nematicidal effect of different glucosinolates and other secondary metabolites extracted from several plant species on the plant-parasitic nematodes Pratylenchus penetrans and Meloidogyne chitwoodi. Glucosinolate extracts from 16 species of genera Brassica, seven Lolium species and one species of Lupinus were used to investigate their nematicidal effect in vitro. From the tested extracts, the one obtained from Brassica juncea (oriental) showed the most promising results, controlling both nematode species. Lupinus sp. also showed positive results when tested against P. penetrans.

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

“…The effect of plant extracts and essential oils in controlling plant-parasitic nematodes is well documented (D'Addabbo et al 2020). However, few studies have been published on the control of M. chitwoodi using plant extracts (Golec 2019). The study focused on the effects of aqueous extracts on the control of Meloidogyne chitwoodi, one of the most widespread root-knot nematodes that infects numerous crops worldwide.…”
