A laboratory experiment revealed that the growth of Parthenium hysterophorus was found restricted by the leaf extracts of Xanthium strumarium. The maximum germination inhibition in Parthenium was recorded in 25% leaf extract of Xanthium Strumarium treatment. Twenty and 25 per cent leaf extract was found to be more potent in reducing the root/shoot length and plant dry weight of Parthenium hysterophorus. A significant reduction was also recorded in seedling vigour and vigour index of Parthenium by the different leaf extract treatment of Xanthium strumarium.
