    • Abstract


      Thirteen leaves, 4 oilcake extracts and 4 root exudates were tested against rootknot nematode,Meloidogyne incognita to study their effect on egg hatch and larval mortality. Aqueous leaf extracts ofDatura stramonium, Parthenium hysterophorus andTagetes erecta and oilcake extracts of karanj and neem were the most potent treatments and they not only inhibited egg hatch but also killed the larvae significantly. The root exudates ofBrassica campestris andTagetes erecta also killed the second stage larvae ofMeloidogyne incognita.
