Description
Summary:Organic amendments and botanical extracts are considered as some of the eco-friendly alternatives to chemical pesticide in suppressing plant pathogenic nematodes (PPN). Root-knot nematode (RKN) is the most important group of PPN distributed globally causing both qualitative and quantitative damage to many crops. Vermicompost and biogas digestate (BD) are two forms of organic amendments reported to have potential to limit RKN infestation. Likewise, marigold (Tagates spp.) and cabbage (Brassica oleracea) are two widely studied botanicals having shown their potential to control RKN. However, there was not much in vitro research related to organic amendments and botanicals targeting a particular species of RKN to observe their nematicidal effect. An in vitro experiment was undertaken to evaluate the effect of these organic amendments and botanical extracts at different concentrations (10.0%, 25.0%, 50.0% and 100.0%) on the hatching and mortality of Meloidogyne javanica at different time spans. Mortality of J2 and inhibition of hatching of egg mass of M. javanica differed significantly (p
