Aqueous extracts of Medicago denticulata, Melilotus indica and Chenopodium album at 5%, 7.5% and 10% significantly reduced plant population of Phalaris minor under laboratory and shade house conditions, thus, indicating the inhibitory role of allelo-chemicals from these weeds. Under laboratory conditions, seed germination and relative germination ratio of Phalaris minor was affected more than wheat with highest reduction in germination under aqueous extract of Melilotus indica, followed by Chenopodium album. 7.5% came to be the best concentration that significantly reduced Phalaris minor germination and optimally maintained wheat population. In tray experiment under shade house conditions, reduction in germination was recorded more under 10% concentration and combined application of weed aqueous extracts. Highest reduction was observed under combined application of Medicago denticulata (10%) + Melilotus indica (10%) + Chenopodium album (10%) that led to only 42.33% emergence in comparison to 85.68% emergence under control. Hence, these weed aqueous extracts can be used as potential herbicides for future weed management programmes as these are natural plant products, easily biodegradable and eco-friendly.
