Abstract:
Studies were carried out to determine the nematicidal effect of Artemisia scoparia, Thymus vulgaris, and Parthenium hysterophorus on Meloidogyne incognita on sunflower by use of aqueous and acetone extracts of leaves and roots. Plant growth parameters of sunflower were significantly enhanced with the application of aqueous and acetone extracts of effective concentrations of leaves and roots of A. scoparia, T. vulgaris and P. hysterophorus. Growth of tested plant including shoot, root length, dry weight of shoot and root were significantly high in aqueous extracts of Thymus leaf and root extract. All the treatments of acetone extracts, Thymus and Artimisia root were effective in enhancing growth parameters of sunflower. The population of Meloidogyne incognita in soil and root, 100 days after inoculation showed significant reduction of nematode population in both extracts of Thymus leaf and root.
