 ABSTRACT

The need for alternatives to nematicides has stimulated research focusing on sustainable and eco-friendly management of plant parasitic nematodes. All the concentrations of the aqueous extracts from fresh leaves of Datura stramonium (20% w/v) caused the mortality of second stage juveniles of Meloidogyne javanicawhereas the more mortality occurred in 1:5 concentration and the least in 1:80 concentration. Juvenile mortality decreased with an increase in the dilution of all the extracts. As an increase in exposure time, juvenile mortality was also increased. Potted soil application of Trichoderma viride @ 20 g/kg of soil was significantly effective against M. javanica and to improve growth parameters of okra. This study also revealed that Azadirachta indica leaves @ 30 g/kg of soil in pots when incorporated, improves the plant growth and reduced the M. javanica infestation in okra. Moreover, D. stramonium,A. indica and T. viride can be used as an alternative in eco-friendly management of root-knot nematode.

Key words:Meloidogyne javanica, Trichoderma viride, Datura stramonium, Azadirachta indica, Eco-friendly management
