Organic agriculture was Europeanized through two EU regulations which defined and provided financial support for it. In transposing these regulations, member states have had to deal with political aspects of the conflict between mainstream and organic agriculture. A comparison of 13 new (including former socialist states) and old member states illustrates that the level of conflict had an impact only on the level of financial support transposed, while other aspects of transposition were explained by formal institutional preconditions. Low financial support was found in those member states with a high level of conflict or a low value-based level of conflict. Medium financial support was found in one new and one old member state characterized by medium level conflicts. High financial support appeared in three member states characterized by truly low level conflicts in terms of common organic and mainstream agriculture interests.
