Importance of allelopathy?

Allelopathy is an interference mechanism based on any direct or indirect effect (primarily inhibitory) by one plant on another through the release of chemicals that escape int…o the environment (Aldrich and Kremer 1997).    This phenomenon is involved in a wide fields of application:    + weed management by the use of mulch or cover crops, especially for those practicing direct drilling.    + Possibility of biological herbicides and insecticides.    + Opportunity of use of crops having stimulatory allelopathic effect in crop rotation, such the case of rapeseed on barley (Oueslati and Ben-Hammouda, 2006).    + For the adversely effect of allelopathy (inhibition of germination, growth and development), it influences choice of rotations, by choosing crops with low allelopathic/inhibitory effect as precedent and the most tolerant ones as following crops.
