Post symposium information

The Second European Allelopathy Symposium, "Allelopathy from understanding to application", was held June 3-5, 2004 in Pulawy,Poland.
The integral part of the Symposium was a workshop on "Fate and toxicity of allelochemicals (natural plant toxins) in relation to environment and consumer" (FATEALLCHEM) - work programme Quality of Life, contract no. QLK5-CT-2001-01967. The sponsor of the meeting was the Polish Ministry of Science and Information Technology. The guest of the Symposium was Mr. Jo Ottenheim, representative of the European Commission.

The 78 scientists from 11 European countries and from Australia, Canada, Mexico, Japan and the USA who attended the meeting discussed the latest achievements and new directions in allelopathy research. In the 8 thematic sessions they have delivered 45 lectures and presented 32 posters.

Abstracts have been published in the Proceedings of the Second European Allelopathy Symposium, "Allelopathy from understanding to application" and FATEALLCHEM WORKSHOP "Fate and toxicity of allelochemicals (natural plant toxins) in relation to environment and consumer" They are also available on the vebpage The full text article will be published in the special issue of Allelopathy Journal.
