Interpretive Summary:

Technical Abstract: This book chapter briefly summarizes role of allelopathy for weed control in aquatic and wetlands. Plants can interfere with each other through allelopathy or competition for resources. Allelopathy can be used in weed management in several ways including cover crops, smother crops, green manure crops, breeding for allelopathic crop cultivars, mulching and crop residue management. Allelopathic suppression of weeds will not replace synthetic herbicides which are dominant method of weed control in many countries nor will allelopathy be economically competitive with herbicides. However, allelopathy can fit in an integrated weed management strategy very well as a vital component. This approach could reduce the sole dependence of synthetic herbicides for solving many complex weed problems. Best examples could be an aggressive rice cultivar for complimenting weed control in direct seeded rice and plant product reinforced classical bio-control (through weevils) of water hyacinth.
