    Abstract : The long-term use reduces the efficiency of the traditional herbicides. The use of plant-extracted natural substances is an alternative more efficient and less aggressive to the environment. The allelochemicalsallelochemicalsSubject Category: Chemicals and Chemical Groups

    for developing an organic herbicide. One of the major problems in this sense is obtaining botanical material in commercial quantities. Improving the extraction techniques is an important step, once it reduces the amount of botanical material needed. In this survey was tested several methods of aqueous extractions of dried leavesleavesSubject Category: Anatomical and Morphological Structures

    with strong allelopathic properties. The time of extraction is not important for the allelopathic potential of the extracts. On the other hand, when the temperature during extraction was 40 e 60°C, leaded to extracts with stronger allelopathic potential. It is possible to improve the allelopathic potential using the filtered matter more than once.
