Glass- house experiment was conducted to test the nematicidal effect of flower extracts of some locally available plants. The flower extracts of five plants are selected for pot treatments to determine efficacy against nematode infection in chickpea var. Avarodhi. The results reveal that the nematicidal efficacy of flower extracts of Calotropis procera were shown highest potential impact against juveniles (J2) of root-knot nematode, Meloidogyne incognita as compared to the tested flower extracts of Tagetes erecta, Lantana camara, Thevetia peruviana and Nerium indicum. However, the extracts of Tagetes erecta, Lantana camara, Thevetia peruviana and Nerium indicum were also significantly reduced the infection in roots as comparision to untreated inoculated control. The plant growth parameters including chlorophyll content and nitrate reductase activity are highly reduced in the untreated inoculated control, while the treated plants are shown the significant improvements in plant growth parameters. The obtained results proved that above tested floral extracts with integrated approach would also be more useful to control nematode infection in economic crops and will be an asset in the clean and pollution free environment.
