Allelopathic effects of "Calotropis" on different agricultural crops have been well studied. Extracts of plant parts such as root, stem, and leaf affect germination and seedling vigor of many agricultural crops. However, extracts of "Calotropis" failed to produce any detrimental effects on weeds such as "Chenopodium album", "Melilotus alba", "Melilotus indica", "Sphaeranthus indicus", and "Phalaris minor".
