We investigate the factors explaining behaviours and attitudes of farmers towards organic practices. Among a wide set of motivational, economic and environmental variables, we focus on those factors related to ethnocentrism of farmers and the importance of local origin labels. We find that ethnocentrism cannot explain neither the present status of farmers (organic vs. conventional) nor their future intentions about the adoption of agricultural methods of production. However, the absence of local origin labels is significantly affecting the choice of conventional farmers who do not convert to organic farming
