The effect of crude aqueous extract of different parts of Adhatoda vasica i.e. fresh leaves, inflorescence and bark on egg hatching and juvenile mortality of Meloidogyne incognita was studied in vitro. Fresh plant material was used to prepare the extracts. Observations were taken after 24, 48 and 72h. Leaf and inflorescence extract were found to be most effective on inhibition of egg hatching after 48h whereas bark extract was found to be less effective. 100% juvenile mortality was observed with undiluted crude aqueous leaf extract whereas inflorescence and bark extract exhibited only 86.66% and 52.66% mortality respectively after 48h.The preliminary phytochemical screening was done to show the presence of secondary metabolites in crude aqueous extract of Adhatoda vasica. https://www.biotech-asia.org/vol6no2/adhatoda-vasica-as-a-potential-nematicidal-source-against-root-knot-meloidogyne-incognita/
