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.
