We investigated the allelopathic effects of A. philoxeroides stem on E. crassipes and found reduction in plant height (32 to 61 %), number of leaves (13 to 38 %), number of branches (20 to 43%) and fresh weight (63 to 73 %). The E. crassipes plants got dried in cisterns treated with A. philoxeroides. The allelochemicals present in A. philoxeroides plants were inhibitory to water hyacinth. The allelopathic leachate of A. philoxeroides caused maximum decrease in growth of E. crassipes, due to presence of alkaloids and phenols. In control, there were no detrimental effects on growth of E. crassipes.
