Abstract

Management of phytoparasitic nematodes with plant products has been supported in favour of the increasedawareness of environmental hazards affecting both flora and fauna associated with pesticides. A glasshouseexperiment was conducted to control the effect of root knot nematode, Meloidogyne incognita on the plantgrowth parameters of chickpea, Cicer arietinum L. var. “Avarodhi”, a highly proteinaceous crop by thedifferent concentrations of leaf extract of Persian lilac, Melia azedarach. Results revealed that the plantstreated with higher concentrations of leaf extracts of M. azedarach showed the least impact of M. incognita ascompared to the other concentrations. Plants inoculated alone with the 1000 second stage juveniles (J2) of M.incognita showed highest reduction in plant growth parameters of shoot and root length (cm), fresh and dryweight (g), number of flowers and pods, total chlorophyll content and nitrate reductase activity with increasedroot knot index. Plants treated with lower concentrations of leaf extract also showed significant control overthe reduction in plant growth parameters. These treatments also reduce the root knot index to a significantlevel. These studies may go a long way and act as a biocontrol agent and will be an asset in the clean andpollution free environment
