Root dip in the extracts of Datura metel, Ricinus communis and Galium aparinoides significantly reduced infection by Meloidogyne incognita on okra. Soil amendment with these plants had a similar effect. Plant growth improved in both types of treatment. Extracts and soil amendments from G. aparinoides had the greatest inhibitory effect on the number of galls per plant and galling index. The inhibitory effects of the three plants on nematode development were ranked as G. aparinoides more than D. metel more than R. communisthe reverse was true for plant growth. These results indicated the nematicidal significance of the three plants.
