摘要： Allelopathy can be utilized to achieve the sustainable weed management either by using allelochemicals as natural herbicides or through allelopathic interactions. More than 2000 plant species (39 families) exert strong allelopathic effects on plants. The allelochemicals are released from the plants through leaching, volatilization, root exudation and the microbial decomposition of deadplant parts. Allelopathic crops are widely used in crops rotations to controlthe growth of surrounding weeds. Cover crops that contain high level of allelochemicals in residues or living mulches are used to suppress the weedS growth for various lengths of time. Although allelopathy is not a solution for all weed related problems in the field but it may significantly help in reducing the weeds population. This review attempts to discuss these aspects of allelopathy for sustainable weed management.
