Plant allelopathy is one of the modes of interaction between receptor and donor plants and may exert either positive effects (e.g., for agricultural management, such as weed control, crop protection, or crop re-establishment) or negative effects (e.g., Cited by: The presence of determined species of weeds, such as purple nutsedge (Cyperus rotundus) and itchgrass (Rottboellia exaltata), mainly in high population densities, may depreciate the market value of the holding, or even jeopardize the dealing of partnership contracts in the infected areas.

The aqueous extracts of C. rotundus revealed allelopathic potentialities on germination of seeds and growth of two vegetable parts (root and aerial part) of all tested species, except on germination of L.

The other important ways may include intercropping of a crop possessing an allelopathic potential with a crop without allelopathic activity [e.g., intercropping of sorghum (Sorghum bicolor (L.) Moench) in cotton (Gossypium hirsutum L.)], including a crop possessing an allelopathic activity in a crop rotation, use of residues from an Cited by: 5.
